How Much Does it Cost to Finish a Basement?
Turning an unfinished basement into a living space can add value to your home and make it more usable. It can also increase its resale value.
Framing the walls of a basement can cost between $7 and $16 per square foot, depending on the number of rooms or divisions that are created. This includes drywall and insulation.
Cost of Materials
Whether you want to turn your basement into an entertainment room, a bedroom, a home office or a workout area, the materials you need can add up quickly. Drywall, insulation and paint all cost money, and framing the walls will increase your total costs.
You’ll also need to pay for electrical wiring and a HVAC system that brings treated air into the basement. If your existing system isn’t sufficient for the new space, a replacement will cost $2,500 to $15,000. Waterproofing will be an additional expense, especially if the walls fail a moisture test or you’re in an area prone to flooding.
Cost of Labor
As with any home improvement project, the amount of labor needed to finish a basement will vary depending on the extent of the work and how elaborate you want it to be. A general contractor will cost more than a handyman, but the extra expense is worth it to ensure your project is done right.
A major factor that will determine how much it costs to finish a basement is whether it has a moisture problem. If the walls pass a moisture test but feel wet to the touch, it will cost $2,500 – $5,000 to repair the issue.
Cost of Electricity
If your basement is unfinished, you'll need to hire an electrician to add new wiring and outlets. On average, this costs $1,300 for small jobs and more than $3,000 for more extensive work.
A new heating system is another costly part of finishing a basement. It costs $24-$38 per square foot to install ductwork in walls, and you'll need to add additional insulation to keep the space warm.
You'll also need to hire a plumber to replumb your basement, which can be expensive. This is especially true if you want to add a bathroom.
Cost of Plumbing
The cost of plumbing will vary depending on the type and number of fixtures you want to install. It can also increase if you need to reroute existing pipes. Typically, this costs more than simply cutting and capping them.
Framing will run $7 to $16 per linear foot for the skeleton of basement walls, based on the number of rooms you’re creating. The walls will need to be insulated, too, so expect to pay for fiberglass batting, blown-in or spray foam insulation.
If the basement has moisture problems, a sump pump will be needed to prevent flooding and damage. This could cost up to $1,000.
Cost of Flooring
Basement flooring is a big expense. It is important to choose a material that is water-resistant and durable, as a basement floor is prone to moisture problems. Adding a subfloor can help to reduce moisture. This costs around $2-$7 per square foot.
It’s also a good idea to waterproof your basement to prevent moisture problems. This can be expensive and is typically done along with foundation repair.
Unless you have a specific reason to divide your basement into rooms, leave the space open. This can save you money on drywall, framing, and electrical wiring.
Cost of Waterproofing
Depending on the level of waterproofing needed, costs can vary. A concrete sealer, for example, can cost $3 to $5 per square foot, including professional labor and materials. Alternatively, you can buy a vapor barrier that looks like clear tarps and attaches to your basement walls for around $1,000.
Porous concrete can be treated with masonry sealer, which costs about $10 per quart and covers five gallons. Waterproofing paint is another option, but it must be applied on bare concrete and will only provide temporary protection from moisture. Draining systems are a more permanent solution, and can cost between $700 and $5,000.
Cost of Decor
If you want to create a more secluded nook for your basement, it’ll cost extra to add things like drywall and lighting. It’s also important to waterproof the space to keep it dry and avoid mold. This can be expensive, though it’s worth it to make your space comfortable.
If you’re turning your basement into a bedroom, you’ll need to install a closet, which can cost up to $15,000. You may also need to paint any exposed pipes and ductwork the same color to help them blend in with the walls.
