Cost to Finish a Basement: Price Per Square Foot (2026)

The cost to finish a basement commonly runs an illustrative $30 to $75 per square foot depending on the finish level, and basement finishing cost is quoted that way for a reason: the per-foot figure travels between sizes better than any total. That per-square-foot range puts a typical mid-range 1,000 square foot basement around $40,000 to $50,000 before you add a bathroom, while a basic finish with simple materials lands lower and a high-end space with plumbing and custom work climbs well above.

That single range hides a lot, because a basement is not just an empty room waiting for paint. It is a below-grade space with its own rules about moisture, egress, and ceiling height, and the choices you make about those things move the number as much as the flooring you pick. This cost file walks through what finishing a basement includes, the illustrative price per square foot and by size, what a bathroom adds, the moisture and code work that has to come first, and the honest tradeoff between doing it yourself and hiring it out. You can sketch your own basement and watch the figure move with the basement cost calculator on this page, which turns your square footage, finish level, and bathroom decision into a live cost band as you read.

What it costs to finish a basement

The honest headline is that the cost to finish a basement depends far more on the finish level and the plumbing than on the square footage alone, but a working range helps. A basic finish, meaning framed and insulated walls, drywall, simple flooring, a ceiling, and basic lighting, commonly lands nearer the low end of the illustrative $30 to $75 per square foot band. A mid-range finish with better materials, more electrical, and perhaps a defined layout of rooms sits in the middle. A high-end finish with a bathroom, a wet bar, upgraded flooring, and custom features runs toward the top and beyond.

It helps to separate two things people blur together. There is the base finish, meaning the work that turns raw concrete and studs into a comfortable, code-compliant room, and there are the add-ons, meaning the bathroom, the kitchenette, the built-ins, and the upgrades that each price as their own project. A great deal of the confusion about basement cost comes from comparing a bare rec room to a full lower-level suite as if they were the same job. They are not, and the rest of this cost file keeps them separate so the numbers make sense.

What finishing a basement actually includes

Before pricing anything, it helps to see everything a finish touches, because a basement is closer to building a small home than to painting a room. A complete finish commonly includes most or all of the following.

• Framing. Building the stud walls that define the rooms and hold the drywall, usually set slightly off the foundation wall.
• Insulation. Insulating the walls, and sometimes the rim joists, to keep the space comfortable and control condensation.
• Drywall. Hanging, taping, and finishing the walls and often the ceiling, then priming for paint.
• Flooring. Installing a floor rated for below-grade use, commonly luxury vinyl plank, engineered product, tile, or carpet over a proper underlayment.
• Electrical. Adding circuits, outlets, switches, and lighting to code, which in a finished basement is a substantial amount of work.
• Egress. Adding or enlarging a code-compliant egress window and well if the basement will have a bedroom or, in many areas, any habitable space.
• Ceiling. Installing a drywall or drop ceiling while preserving access to the systems that run overhead.
• Permits and inspections. Pulling the permits and passing the inspections that make the space legal habitable square footage.

Seen as a list, the reason a basement costs what it does becomes clear. You are not finishing one surface, you are building framing, systems, and finishes across an entire floor of the house, each with its own materials and labor. Skipping items on that list does not usually save money so much as it moves the project out of the category of a real, permitted finish.

Cost to finish a basement per square foot

Per square foot is the way most homeowners first think about basement cost, and the illustrative range is roughly $30 to $75 per square foot for the base finish, before a bathroom. A basic finish tends to sit near $30 to $45, a mid-range one near $45 to $70, and a high-end one from $70 up, sometimes well past it once premium materials and custom work enter the picture. The number reflects everything on the list above spread across the floor area.

A caution about per-foot math: it is a useful sanity check, not a quote. A small basement carries fixed costs, such as a bathroom, a mechanical room to work around, and permit fees, that do not shrink with the floor area, so a small space often costs more per foot than a large one. A cut-up basement with support posts, a furnace, ductwork, and awkward corners costs more per foot to frame and finish than a large open rectangle. Use the per-foot figure to get in the right ballpark, then adjust for the shape and obstacles of your actual space. Our broader cost file on what it costs to hire a contractor explains why the labor underneath these per-foot numbers varies so much by region.

Average cost to finish a basement

The average cost to finish a basement is commonly cited in the illustrative range of about $20,000 to $60,000, with many mid-range projects clustering somewhere near $40,000 to $50,000. That is a wide band, and the width is the honest part, because the word “basement” covers everything from a single open room with laminate flooring to a full lower level with a bathroom, a bedroom, a media room, and a bar.

The average is worth exactly one thing: framing the conversation. It tells you that a finished basement is a five-figure project rather than a weekend job, and that a quote of a few thousand dollars almost certainly leaves out something real. Beyond that, the average cannot see your basement, your region, your moisture situation, or your plans, so it should never stand in for a quote. The most useful move is to treat the average as a starting altitude, then use the size, finish, and bathroom details in the sections below to land on a figure that fits your own space. Run your numbers through the job cost estimator to get a personalized illustrative range rather than a national one.

What shapes a finished basement price

A finished basement price is not one number, it is the sum of choices, and the same phrase can describe very different projects for two different homeowners. When someone asks about the finish basement cost for their home, the honest answer starts with the finish level, because a basic open rec room and a full lower-level suite with a bathroom sit at opposite ends of the same range. The illustrative $30 to $75 per square foot band exists precisely because the finished basement price stretches that far depending on the materials, the layout, and the systems involved.

Two levers move the finished basement price more than any other. The first is the plumbing decision, since a bathroom is priced as its own job and can add a rough $8,000 to $20,000 regardless of the room’s size. The second is the condition of the raw space, because moisture work, an egress window cut into the foundation, or a raised subfloor to gain ceiling height all add to the finish basement cost before a single wall goes up. The cost to finish basement space that is already dry, tall, and roughed in for plumbing sits far below the cost for one that needs all three fixed first. Price the base finish by area, then add each system as its own line, and the finished basement price stops feeling like a mystery and starts looking like the reasonable sum of the choices you actually made.

Cost to finish a basement by size

Because so much of the finish is priced by area, the total scales with the size of the basement, and seeing the shape makes it concrete. The bars below apply an illustrative mid-range rate to three common sizes, plus a 1,000 square foot basement with a bathroom added, so the pattern rather than the exact dollars is the point.

The lesson in the bars is that size sets the base and the bathroom bends it. A 1,000 square foot basement with a bathroom can cost more than a larger basement without one, because the plumbing is a fixed job that does not care how big the room is. That is why budgeting by square foot alone misleads, and why the smart approach is to price the base finish by area and then add the bathroom, the bar, and any other systems as their own lines on top.

Cost to finish a 1,000 sq ft basement

A 1,000 square foot basement is the most common size homeowners ask about, so it is worth its own answer. Finishing one commonly costs an illustrative $30,000 to $75,000, with a typical mid-range project landing around $40,000 to $50,000 before a bathroom. At the low end sits a basic finish: framed and insulated walls, drywall, a simple ceiling, luxury vinyl plank flooring, and basic lighting across one or two open rooms. At the high end sits a fully built-out lower level with premium flooring, recessed lighting throughout, multiple defined rooms, and upgraded finishes.

Where your own 1,000 square foot job lands depends on a few levers. The finish level is the biggest, since premium materials and more complex layouts add up across the whole floor. The condition of the space matters next: a dry, tall, already-roughed-in basement finishes cheaply, while one that needs moisture work, an egress window cut into the foundation, or a raised subfloor to gain height costs more before a single wall goes up. And a bathroom, covered next, sits on top of all of it. The way to turn this range into a number is to define your finish level and your bathroom decision, then price them separately.

Cost to finish a basement with a bathroom

Adding a bathroom is the single choice most likely to swing a basement budget, and it deserves careful thought. The illustrative add is commonly in the rough range of $8,000 to $20,000 on top of the base finish, and the spread is almost entirely about plumbing. A basement sits below the home’s main drain line, so wastewater often cannot simply flow downhill to the sewer the way it does upstairs. Getting drainage, venting, and supply lines to a below-grade bathroom is a genuine plumbing project, not a fixture swap.

The cost hinges on one question: how does the waste get out? If the builder roughed in plumbing when the house was built, meaning the drain and supply stubs are already there, adding the bathroom is far cheaper and lands near the bottom of that range. If there is no rough-in, the options each carry a cost. Cutting the concrete slab to run new drainage and tie into the main line is the most thorough and often the most expensive route. A sewage ejector pit or an upflush macerating system can move waste up to the main line without cutting as much concrete, at a different cost and with its own tradeoffs. Because these paths differ so much, a basement bathroom is the line item to price first and price carefully, ideally with a plumber who has seen the space.

Cost to finish a basement with a kitchenette or wet bar

After a bathroom, the add-on that moves the cost to finish a basement most is a kitchenette or a wet bar, and for the same underlying reason: water. A simple wet bar with a sink means a supply line, a drain, and a vent reaching a spot that was never plumbed, plus cabinets, a countertop, an outlet or two on the right circuit, and often a small under-counter refrigerator. Illustratively that is a several-thousand-dollar add on top of the base finish when the plumbing path is easy, and considerably more when it is not.

A full kitchenette raises the stakes again. Add a range or a cooktop and you are into ventilation, a dedicated circuit, and possibly gas; add a dishwasher and you are into a second drain connection; add real cabinetry and countertops and you are buying a scaled-down kitchen at kitchen prices per foot. This is worth pricing against our kitchen remodel cost file rather than against the basement’s per-square-foot band, because it behaves like a kitchen, not like a rec room.

The below-grade wrinkle that catches people is drainage height. A basement floor commonly sits below the main sewer line, so a new sink or dishwasher drain may need a pump rather than gravity, which is an extra piece of equipment, an extra electrical connection, and an extra thing to maintain. If the basement was roughed in for plumbing when the house was built, the whole add gets much cheaper, so the first question to ask is where the existing stubs are. There is also a code and appraisal dimension: in some jurisdictions a basement with a full cooking setup and its own entrance starts to look like a second dwelling unit on paper, which brings a different permit path. Confirm the rules locally before you commit to a range rather than a microwave, and price the bar or kitchenette as its own line in the basement cost calculator rather than folding it into the finish level.

Moisture and waterproofing come first

This is the section homeowners most often wish they had read sooner. A basement is below grade, surrounded by soil that holds water, and controlling moisture is not an optional upgrade, it is the prerequisite that everything else depends on. Finishing over a basement that takes on water or stays damp is how brand-new drywall grows mold, new flooring buckles, and a $45,000 project has to be torn out and done again. The cheapest waterproofing is the kind you do before the walls go up.

Before framing, the space should be dry and stay dry. That can mean grading soil away from the foundation and extending downspouts so water drains away from the house, sealing visible cracks, addressing any history of seepage, and in some cases installing an interior drainage system or a sump pump. It also means controlling humidity, since a basement can be dry of liquid water and still be humid enough to cause problems, which is why many finished basements run a dehumidifier. None of this is glamorous and some of it is invisible once the walls are closed, but it is the foundation the whole finish sits on. Spend here first, verify the space stays dry through a wet season if you can, and only then start building. Skipping this step to save money is the classic basement regret.

The egress window requirement

Egress is a safety and code item that surprises many first-time basement finishers, and it belongs in the budget from the start. An egress window is a window large enough for a person to climb out of in an emergency, and for a firefighter to climb in, set at a code-specified size and height with a window well if it is below grade. In most areas, any basement bedroom is required to have one, and many jurisdictions require egress for other habitable spaces as well.

The reason egress matters to the budget is that adding one to an existing basement is not trivial. If a large enough opening does not already exist, cutting one into a poured concrete or block foundation, installing the window and a proper well, and doing it without compromising the structure is a real job with a real cost. Homeowners sometimes try to avoid it by calling a below-grade sleeping room something else on paper, which is exactly the kind of shortcut that creates problems at sale time and, more importantly, defeats the safety purpose of the requirement. If your basement plan includes a bedroom, price the egress window as a required line, confirm your local rules with the building department, and treat it as non-negotiable rather than optional.

Ceiling height and what code expects

Ceiling height is a physical constraint that can shape or even limit a basement finish, and it is worth checking before you fall in love with a plan. Building codes commonly set a minimum finished ceiling height for habitable basement space, and a finished ceiling is lower than the raw one because framing, drywall, and flooring all eat into the clearance. Ductwork, beams, and pipes that hang below the joists lower it further in spots.

If your basement has generous height, this is a non-issue and you have room to run a drywall ceiling and cover the systems cleanly. If it is tight, the finish gets more complicated and sometimes more expensive. Options include a drop ceiling that preserves access but consumes some height, boxing in or rerouting low-hanging ducts and pipes, or, in extreme cases, lowering the floor, which is a major structural undertaking that can dwarf the rest of the budget. Most finishes never need anything that drastic, but every basement finish has to reckon with the height it has. Measure early, check your local minimum, and design the ceiling and any soffits around the clearance you actually have rather than the one you wish you had.

Permits and inspections

Finishing a basement almost always requires a permit, and that is a feature, not a burden. You are creating habitable living space and typically adding electrical, sometimes plumbing, and often an egress window, all of which are inspected because getting them wrong is dangerous. The permit and inspection process is what confirms the wiring is safe, the egress is adequate, and the space is legal square footage that will not become a problem later.

Skipping the permit can look cheaper and faster, and it is a false economy. Unpermitted finished space can surface when you sell, can create insurance complications if something goes wrong, and can force expensive rework if a later inspection finds it. It also skips the safety checks that protect the people living in the space. Permit costs vary by area and are usually a modest share of the total, and a good contractor handles the permits and inspections as part of the job. If you are managing the work yourself, contact the building department early, because the requirements for egress, ceiling height, smoke and carbon monoxide detection, and inspections are all local and are far cheaper to design around than to retrofit.

Labor versus materials: where the money goes

Understanding how a basement budget splits helps you judge quotes and decide where to spend your own effort. On a professionally finished basement, labor is commonly around half of the total, sometimes a little more, because framing, hanging and finishing drywall, electrical, and plumbing are all labor-intensive trades. Materials make up much of the rest, with permits, egress, and equipment filling out the remainder. The stacked bar below shows an illustrative split of a mid-range finishing budget across its major pieces.

The split explains why two quotes on the same basement can differ. A large share of the money is labor, and labor rates vary by region and by how busy the trades are, so the same materials list prices differently across town lines. It also explains where do-it-yourself effort has the most leverage: the framing, insulation, and drywall band is the biggest, and it is the part a capable homeowner can most realistically take on. Our cost file on how much a general contractor costs covers the coordination fee that sits on top of these trades when one professional runs the whole job, and the broader hiring cost file breaks down the labor, materials, overhead, and profit inside any single trade’s bid.

DIY versus professional basement finishing cost

The do-it-yourself question is where the biggest savings and the biggest risks both live, so it deserves an honest answer. Because labor is roughly half of a professional finish, a capable homeowner who supplies the work can save a large share of the total, which is why basements are a popular DIY project. The materials cost the same either way, but the labor is yours to give. On a $45,000 mid-range job, doing much of the work yourself could bring the out-of-pocket cost down substantially, though never to zero.

The honest line is about which parts to keep and which to hire out. The framing, insulation, and drywall are the largest band and the most DIY-friendly, since mistakes there cost time and material rather than safety. Painting, trim, and flooring are also common homeowner tasks. The trades to think hard about hiring are the ones with code and safety weight: electrical, plumbing, and any egress or structural work. A wiring error is a fire risk, a plumbing error is a water-damage risk, and an egress window cut wrong compromises the foundation, so these are the places where a licensed pro earns the cost. A common and sensible middle path is to do the demolition, framing, insulation, and finishing yourself while hiring pros for the electrical, plumbing, and egress. Be honest with yourself about your skills, your available time over the months a basement takes, and your local permit rules, which sometimes require licensed trades for certain work regardless of who else is on the job.

Cost to finish a basement in phases

Plenty of homeowners cannot fund the whole job at once, and phasing is a legitimate way to spread the cost to finish a basement across two or three budgets. The version that works splits the project along natural boundaries: do the unglamorous, hard-to-retrofit work first, then add the finishes later. That means moisture control, any egress window, the rough electrical and rough plumbing, and the framing and insulation go in phase one, while flooring, the ceiling, trim, built-ins, and the bathroom fixtures wait for phase two.

The version that does not work splits the job by room, finishing one end completely while the other end sits raw. That approach forces a crew to mobilize twice, cut into finished walls to run wire or pipe to the second half, and repeat the dust-control and inspection cycle, all of which costs more in total than doing it once. As a rough planning assumption, expect a phased project to run somewhat higher all-in than a single continuous build, illustratively on the order of ten percent or so, because setup, mobilization, and permit sequencing get paid for twice.

Permits deserve special thought when phasing. Building permits are typically issued against a defined scope with an expiry and a required inspection sequence, so a plan that stalls for a year between phases can mean a lapsed permit and a second application fee. The clean approach is to talk to the building department and the contractor about phasing before the first permit is pulled, so the scope, the inspection points, and the timeline are agreed in advance rather than improvised. Priced that way, phasing buys you time at a modest premium instead of an expensive surprise, and it lets the family use a dry, framed, lit basement while the finish budget rebuilds.

Cost to finish a basement versus an addition or an attic

When the goal is more living space rather than a finished basement specifically, the honest comparison is against the alternatives, and the basement usually wins on price per square foot. A basement finish starts with a floor, four walls, a roof, and a foundation that already exist and are already paid for, so the illustrative $30 to $75 per square foot buys interior work only. A ground-floor addition has to buy all of that structure from scratch, plus excavation and a new roofline tie-in, which is why additions commonly price at a multiple of the basement figure per square foot.

An attic conversion sits between the two. Like a basement, it uses an existing shell, so it avoids foundation and roof costs. Unlike a basement, it frequently needs structural work to carry a floor load the framing was never designed for, plus a permanent stair that eats floor space on the level below, plus dormers or a raised ridge if the head height is short. Whether an attic beats a basement on price depends almost entirely on how the roof was framed and how much head height already exists.

What the basement gives up in exchange for its low per-foot cost is daylight and appraisal treatment. Below-grade square footage is generally valued differently from above-grade space, so a finished basement and an addition of identical size do not land the same way on an appraisal, even if both are comfortable and permitted. That does not make the basement a worse decision, it makes it a different one: the basement is usually the cheapest route to usable space you will enjoy now, while an addition is the more expensive route to space that counts more fully later. If a garage build is also on the table, our cost to build a garage playbook prices that third path on the same terms.

Does finishing a basement add value?

Homeowners often justify the cost as an investment, so it is worth being straight about the return. Finishing a basement generally does add value and, just as importantly, adds usable living space, but it commonly recoups only part of its cost at resale. Figures cited for the payback vary, but they often land in the rough illustrative range of 60 to 75 percent of what you spend, meaning you should not expect to get every dollar back when you sell.

A few things shape where in that range a given basement lands. Quality matters: a finished space that is genuinely comfortable, dry, well lit, and permitted adds more value than one that feels like an afterthought or was done without permits. Appraisers also commonly treat below-grade square footage differently from above-grade space, so a finished basement does not usually count toward the home’s value the way an addition on the main floor would. The healthiest way to frame the decision is that you are buying living space you and your family will use now, with partial money back later, rather than a pure financial investment. If the space genuinely improves how you live in the home, the partial payback is a bonus rather than the point.

Where to save and where not to

Once the plan is set, the question becomes where to trim without regret, and a basement has clear answers on both sides. The places to save are the ones where a cheaper choice does not cost you later: flooring and finishes can start modest and be upgraded down the road, a drop ceiling can stand in for drywall to save money and preserve access, and doing your own demolition, framing, and painting keeps labor dollars in your pocket. Lighting and paint are cheap ways to make a space feel finished, so there is room to be frugal on the cosmetic layer.

The places not to save are the ones where cutting corners costs far more than it saves. Moisture control and waterproofing come first on that list, because a wet basement destroys everything built on top of it. Electrical and plumbing done to code by qualified hands are not the place to economize, since the failures there are dangerous and expensive. Egress and permits are non-negotiable safety and legal items, not optional upgrades. And skimping on insulation or a proper subfloor can leave the space cold, damp-feeling, and unpleasant to use, which defeats the purpose of finishing it at all. The rule of thumb is simple: save on the things you can change later, spend on the things that are buried in the walls or that keep the space safe and dry.

Heating and cooling the finished space

A newly finished basement needs to be comfortable year round, and how you condition the space is an easy thing to overlook until the first cold month. Basements are naturally cooler and can be damp, so the finished space usually needs heating, sometimes supplemental cooling, and almost always some humidity control. The cost and approach depend on your existing system and the size of the space.

If the home’s forced-air system has capacity to spare, extending ductwork with new supply and return runs into the basement is often the simplest path, though it consumes some ceiling height and adds to the finishing cost. If the existing system is already at its limit, adding load can overtax it, and options such as a ductless mini-split, electric baseboard, or in-floor heat may make more sense for the basement specifically. Humidity is the other half of comfort: even a dry basement often benefits from a dehumidifier, and many finished basements run one routinely. Plan the conditioning of the space during design, not after the drywall is up, because running ducts or wiring for heat is far easier before the walls are closed. Comfort is part of what you are paying for, and a finished basement nobody wants to sit in because it is cold or clammy is money poorly spent.

A worked example: a 1000 sq ft basement with a bathroom

To pull it together, walk through an illustrative mid-range project: a 1,000 square foot basement finished to a comfortable mid-level standard, with a full bathroom added. Start with the base finish. At an illustrative $45 per square foot for a mid-range finish, the 1,000 square foot base comes to about $45,000, covering framing, insulation, drywall, flooring, a ceiling, electrical, lighting, and the trim that makes it a real room. That figure already assumes the space is dry and does not need major moisture work.

Now add the systems and requirements. Say the basement needs an egress window cut into the foundation for a bedroom, an illustrative several thousand dollars, and a full bathroom with plumbing that ties into an existing rough-in, an illustrative $8,000 on the lower end of the bathroom range because the drain was already stubbed in. Add permits and a contingency for the surprises a below-grade space tends to hide, and the all-in total lands somewhere near $53,000 to $58,000 for a permitted, comfortable, code-compliant finished basement with a bedroom and a bath. Change any assumption, meaning the finish level, the bathroom’s plumbing path, or how much you do yourself, and the total moves accordingly. That is exactly the sketch the companion below lets you rebuild with your own numbers, so you can watch your low and high estimates and your cost per square foot move as you change the size, finish, and bathroom decision.

How to read a basement-finishing quote

A basement quote is easy to misjudge because so much of the work is hidden inside the walls, so knowing what to look for protects you. A strong quote is itemized enough that you can see the major pieces: framing and drywall, electrical, any plumbing, flooring, the egress window if one is needed, and the permit. A quote that is one lump sum with no breakdown makes it impossible to compare bids or to see what was left out, and on a project this size that opacity is worth pushing back on.

Watch especially for the things a low bid quietly omits. A quote that does not mention moisture control on a basement with any seepage history is leaving out the most important step. A bid with no line for the egress window on a plan that includes a bedroom has either missed a code requirement or assumed you will handle it. A bathroom priced suspiciously low may assume an easy plumbing path that your basement does not have. The way to compare fairly is to hold every quote against the same defined scope, meaning the same finish level, the same rooms, the same bathroom, and the same egress and permit assumptions, so the numbers describe the same project. Our cost file on how to compare contractor quotes walks through normalizing bids that price things differently, and it applies directly to a job with as many moving parts as a basement. Run your plan through the basement cost calculator beside this cost file first so you walk into those conversations with a realistic base number to test each bid against, and if you sanity-check a bid’s labor line the embeddable job cost estimator turns local labor rates and estimated hours into the same kind of ballpark for any trade.

The bottom line

The cost to finish a basement comes down to the finish level, the size, and the plumbing, and a working range is an illustrative $30 to $75 per square foot for the base finish, which puts a mid-range 1,000 square foot job around $40,000 to $50,000 before a bathroom. A bathroom is the biggest swing, commonly adding a rough $8,000 to $20,000 because below-grade plumbing is its own job, and moisture control, egress, ceiling height, and permits are requirements to build into the budget from the start rather than surprises to meet later.

The homeowners who finish a basement without regret are the ones who got the order right: dry the space first, plan the code items early, price the bathroom as its own line, and be honest about what they can do themselves versus what belongs to a licensed pro. Do that, collect several detailed quotes on the same defined scope, and the number stops feeling like a mystery and starts looking like what it is, the reasonable price of turning an entire floor of raw space into a room your family will actually use.

ProsNook publishes this cost file to help homeowners understand how basement finishing is priced, not to quote your project or serve as professional, legal, structural, or financial advice. Every dollar figure, per-square-foot range, and percentage here is illustrative and general, and the real cost to finish a basement moves with your region, the size and condition of the space, moisture and structural factors, the plumbing path for any bathroom, local code and permit requirements, and current market conditions. Egress, ceiling height, and permit rules in particular are set locally and vary widely, so confirm them with your building department before you plan. Before you commit, get detailed written quotes from licensed, insured contractors, have any moisture, structural, or electrical work assessed by a qualified professional, and verify current pricing for your own area.
