Basic basement finishing costs $49 to $65 per square foot in Baltimore, MD, 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 $24,500 to $32,500 total, while a large, 1,500-square-foot basement will cost $73,500 to $97,500 to finish.
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: Typically 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 $1,250 on average, while DIY paint runs $20 to $70 per gallon (averaging $30 per gallon).
Egress Windows: Egress windows cost $4,000 to $10,000 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 $500 to $1,900, while interior doors range from $225 to $825 each. Exterior access is particularly useful for guest suites.

A sump pump will cost $925 to $3,500 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.
To avoid soggy stuffed animals and wet carpet, waterproofing your basement will cost an additional $6,500 on average, or about $3 to $15 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.
Acquiring the necessary building permits will add $200 to $1,000 to 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.
It’s always worth the investment to hire a trusted basement remodeling company in Baltimore, MD.

You’ll also need to factor in labor costs for a few other pros needed for your basement finishing project, including:
Electricians: Connect power to the basement, charging $100 to $200 per hour.

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.
