Finishing a Basement Cost Factors 

The most important cost factor of finishing a basement in Dallas, TX, is project scope, but the size of the space, the materials you choose, and add-ons like waterproofing and egress doors also affect costs.

Project Scope

Your final basement finishing cost relies on your starting point. In some cases, you might not even have an unfinished basement to work with, so you’ll have to factor in the cost to build one. On the other hand, you might already have a built or semi-built space that just needs remodeling to turn it from an unfinished to a finished basement.

Square Footage

Basement finishing costs vary by size, with larger spaces increasing total project costs.

Basement finishing costs about $25 to $50 per square foot in Dallas, TX, so the larger the space, the more you’ll spend to turn it into a cozy den or welcoming guest suite. A smaller, 500-square-foot basement will cost about $12,500 to $25,000 to finish, while a larger, 1,500-square-foot basement will cost $37,500 to $75,000.

Materials

The materials you choose will play a major role in your overall basement finishing cost, with prices varying based on quality, durability, and design preferences. Higher-end materials and finishes will raise your total cost, while standard options help keep the project within budget, so it’s important to balance where to spend and save.

• Flooring: Costs $1,500 to $4,500 total (around $3,000 for 500 sq. ft.), with hardwood reaching up to $25 per square foot and carpet or laminate ranging from $2 to $8 per square foot.

• Paint: A professional paint job costs $1,800, while DIY paint runs $30 to $70 per gallon (averaging $50 per gallon).

• Egress Windows: Egress windows cost $2,500 to $6,000 each, including installation, though permits and excavation can increase costs, and they add natural light and value to the space.

• Door Installation: Exterior basement entrances cost $290 to $1,700, while interior doors range from $230 to $600 each. Exterior access is particularly useful for guest suites.

Sump Pump Installation

A sump pump will cost $600 to $2,500 to install. This system is crucial for, you guessed it, pumping out large volumes of water that might accumulate from rain, a bad plumbing day, or any other event that could lead to flooding.

Waterproofing

To avoid soggy stuffed animals and wet carpet, waterproofing your basement will cost an additional $5,000 on average, or $3.50 to $10 per square foot. Your final basement waterproofing cost depends on the method you use and the extent of work required. Depending on your local climate, there may be a best time of year to finish your basement, since waterproofing can’t always be done in all temperatures. For the best results, find a basement waterproofing contractor near you.

Building Permits and Code Requirements

Acquiring the necessary building permits will make up about $1,200 to $2,000 of your total cost to finish a basement. Some municipalities will charge permit fees of 1% to 2% of your basement remodel project. A contractor will usually include this in your service package, but if you’re handling the building yourself, be sure to factor it into your budget.

General Contractor Costs

When it comes to a major project like this one, there’s no substitute for the skill and experience you get when you work with a basement remodeling company in Dallas, TX. You’ll need to budget for labor costs to hire a basement finishing pro, which will cost between $25 to $50 per hour for general labor. Working with an expert ensures quality work, a good return on investment (ROI), compliance with finished basement building codes, and, most importantly, a beautifully finished basement.

Additional Pros to Consider Hiring 

There are a few other costs to consider for this project—namely, labor rates for the other pros you need to hire to finish your basement:

• Electricians: Connect power to the basement, charging $60 to $120 per hour.

• Plumbers: Install fixtures, water, and sewage lines for $45 to $200 per hour.

• HVAC Techs: Install heating, air conditioning, and ventilation, costing $75 to $200 per hour.

• Drywall Installers: Add walls and ceilings after framing is in place, costing $40 to $100 per hour.

• Painters: Put the finishing touches on your finished basement for $25 to $75 per hour.

Does Finishing a Basement Increase Home Value?

The effect that finishing a basement has on home value can’t be overstated—especially in Dallas, where clay soil makes basements much rarer than elsewhere in the country. If you invest in quality work and higher-end materials, your new basement could yield a return on investment (ROI) of 60% to 75%.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
