How Much Does It Cost Per Square Foot to Finish a Basement?

The average cost to finish a basement ranges between $35 and $150 per square foot. Some professionals, however, may charge less. What is the cost to finish 800 Square ft basement?

Square Footage in Total

Estimated Beginning Cost

500 $17,500

700 $23,800

800 $28,000

1,000 $35,000

1,200 $42,000

1,500 $52,500

2,000 $70,000

The total square footage of your basement isn’t the only factor contractors consider when preparing estimates. They consider all aspects of a job, such as the materials and skilled labor required, as well as the amount of time and permits required to complete the basement. Using these details, they can generate a quote with a cost per square foot that includes all of the work that needs to be done.

When basements are small, the cost per square foot may rise because the amount of work remains high, and the company must charge a minimum fee to cover the cost of doing business. A contractor cannot provide an accurate estimate until he or she has seen the project in person.

Factors Influencing Basement Finishing Costs

The price of basement electrical wiring

If a basement lacks wiring, a professional electrician or contractor licensed to do electrical work can safely install it. Installing electrical outlets in a basement typically costs $75-$500. The lower the cost per item, the more switches and outlets installed.

Cost of a Finished Basement Floor

The cost of refinishing a basement is also affected by the flooring you choose. Staining the existing concrete may be the most cost-effective option. It will be more expensive to hire professionals to install carpet, vinyl, tile, or hardwood floors.

Cost per square foot of flooring

Carpet $3-$6

$2.50-$3 for ceramic tile

Concrete $3-$10

Engineered hardwood


100% solid wood


$3-$10 for porcelain tile

The Cost of Basement Plumbing

Installing a laundry room, basement bathroom, or kitchen all necessitates the installation of water and drainage pipes. Professional plumbers and some licensed contractors can install the system safely if there are no existing plumbing lines in the basement. Plumbers charge between $450 and $1,000 per fixture.

Basement Drywall Prices

Drywall installation costs between $30 and $60 per panel, or between $649 and $1,200. These estimates include both material and labor costs.

Windows for Egress

Unless your basement already has a direct window or door access to the outdoors, local building codes may require the installation of exit windows (for emergencies) when converting a bare basement into livable space or sleeping quarters. Adding an egress window may necessitate excavating the land and re-framing a portion of an exterior wall to meet this building code, resulting in a higher overall cost.

Material costs

The cost of basement refinishing is heavily influenced by materials. A high-end basement straight out of a remodeling magazine will cost more than a basic basement finished with contractor-grade (entry-level) flooring and fixtures.

Repairs and damage

Addressing any needed repairs before finishing a basement is a good idea, but it will also raise the overall cost of your project. Furthermore, if contractors discover water damage, termite evidence, or structural issues during a finishing project, the timeline will be pushed back and costs will rise.

How much does it cost to finish a basement bathroom?

Depending on whether plumbing lines already exist or must be installed, as well as the quality of fixtures and other materials are chosen, the cost to finish a basement with a bathroom could range from $3,000 to $15,000, or even up to $30,000. A standard full bathroom with a shower should cost around $5,000.

Keep in mind that the cost may be lower if the cost is rolled into a larger basement finishing project rather than a standalone basement bathroom addition.

Basement Waterproofing Costs

Waterproofing a basement costs between $500 and $3,500. Basement waterproofing will most likely be less expensive if it is part of a larger basement finishing project than if you hire someone to do it alone. Basement waterproofing employs a variety of techniques to ensure that water seepage and collected moisture do not damage your foundation or introduce mold into your home. Before renovating your basement, talk to your general contractor about what steps, if any, need to be taken to waterproof your basement. Ignoring moisture issues and installing flooring and drywall before waterproofing your basement will cost you more money in the long run.

Installing a sump pump is one way to deal with water that has accumulated due to leaks, poor drainage, or foundation seepage. Southern Belt Construction is best to contact basement remodeling Houston.

Basement Remodeling Costs

The average cost of remodeling a basement is $18,500. Overall, costs can range from $5,000 to $70,000. Basement remodeling differs from basement finishing from a technical standpoint. Remodeling a finished basement usually entails changing the structure or layout.

How to Hire a Contractor

Begin your search for a contractor to help you finish your basement by searching for professionals online. Read online reviews from previous customers to get a sense of their experience and expertise. You should also look for photos of basements that the contractors have completed. Once you’ve identified several potential contractors, contact them for cost estimates.

What features and finishes do you want to include? When do you want the project finished?
