How Much Does It Cost to Finish a Basement in Raleigh, NC? [2026 Data]

Raleigh, NC, has a slightly lower cost of living than the national average, which can help reduce some of the costs of finishing a basement. The average cost to finish a basement in Raleigh, NC, is $31,424, but prices can vary widely, ranging from $14,730 to $73,650, depending on project size, the rates of the professionals you hire, permitting fees, and a few other cost factors.

Finishing a Basement Cost Factors 

The most important cost factor of finishing a basement in Raleigh, NC, is the scope of the project, but the size of the space, material choices, and add-ons like waterproofing will affect costs too.

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 basement 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 $7 to $23 per square foot in Raleigh, NC, 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 between $3,500 to $11,500 total, while a large, 1,500-square-foot basement will cost $10,500 to $34,500 to finish.

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: Typically costs between $3,500 to $7,500 total (about $4,000 for 500 sq. ft.), with hardwood reaching up to $20 per square foot and carpet or laminate ranging from $2 to $9 per square foot.

• Paint: A professional paint job costs $1,650 on average, while DIY paint runs between $30 and $50 per gallon (averaging $40 per gallon).

• Egress Windows: Egress windows cost between $2,500 to $5,000 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 $470 to $2,155, while interior doors range from $170 to $310 each. Exterior access is particularly useful for guest suites.

Sump Pump Installation

A sump pump will cost between $1,500 and $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.

Waterproofing

To avoid soggy stuffed animals and wet carpet, waterproofing your basement will cost an additional $4,500 on average, or $3 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 $1,160 to $1,350 of your total cost to finish a basement. You’ll pay an additional fee of 0.35% of the calculated construction value 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

There’s no substitute for the skills, equipment, and expertise you get from hiring a basement remodeling company in Raleigh, NC. These professionals will work according to finished basement code requirements, pull all necessary permits on your behalf, and ensure a quality end result when the project is completed. While rates vary to hire a basement finishing pro, you can generally expect yours to charge between $25 and $100 per hour in Raleigh, NC.

Additional Pros to Consider Hiring 

You’ll likely need to hire a few additional pros for your basement finishing project, including:

• Electricians: Connect power to the basement, charging $37 to $75 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 service call.

• 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 $20 to $50 per hour.

Does Finishing a Basement Increase Home Value?

You could see a major home value increase from finishing your basement in Raleigh, NC. While exact return on investment (ROI) figures vary based on the quality of the work and the amount of square footage your basement adds to the home, you can generally expect to see an ROI of 50% to 75% from this project.

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.
