📍 Serving Arlington, Fairfax, Loudoun & Prince William County, VA
Your basement is the most cost-effective square footage you already own, it just needs to be finished right. Building America Construction (BAC) turns dark, unused below-grade space into fully permitted, livable rooms: in-law suites, home theaters, offices, gyms, and guest suites with full baths. With 15+ years in business and 300+ completed projects, we handle basement remodeling from moisture control and egress all the way through the final coat of paint, using our own in-house trades at every step.

What a Basement Remodel Costs in Northern Virginia
Every basement is priced by scope, not by a flat rate, but most projects in our area run $35,000 to $90,000 or more. A straightforward open rec room with framing, drywall, lighting, and flooring sits at the lower end. A full finish that adds a bathroom, a wet bar, or a legal bedroom with an egress window climbs toward the top and beyond. The biggest cost drivers are square footage, whether you add plumbing, egress and waterproofing needs, and the level of finishes you choose. These are ranges, not quotes. The only way to know your number is a walkthrough, so reach out through our contact page and we will give you a clear, itemized price for your space.
What Drives Your Basement Budget
Every basement is different, so the investment depends on scope rather than a flat rate. The biggest factors include:
- Adding a bathroom, below-grade plumbing, and sometimes a sewage ejector pump, adds cost and complexity.
- Egress requirements, cutting a window well through a foundation wall for a legal bedroom is significant work.
- Ceiling height and structure, low clearance, ductwork, or beams may require creative framing.
- Moisture conditions, a basement needing waterproofing or drainage costs more to prepare.
- Finish level, a simple rec room differs from a full suite with a kitchenette, custom bar, or home theater wiring.
We spell all of this out during your quote so you know exactly what you are paying for.
How Long a Basement Remodel Takes
Most finished basements take 6 to 10 weeks once construction begins. Adding a bathroom, cutting in an egress bedroom, or building custom features like custom built-in cabinets extends that timeline, because those trades and details take more time to do right. Permitting adds time on the front end before any framing goes up. During your consultation we give you a realistic timeline for your specific scope so you can plan around it.
Our Basement Remodeling Warranty
Every basement we finish is backed by BAC’s 1-year workmanship warranty, put in writing on everything we build. On top of that, the products we install carry their own manufacturer warranties, so your flooring, fixtures, and materials stay covered by the companies that make them. If something is not right within the warranty period, our own in-house crews come back and take care of it.
Frequently Asked Questions
How much does it cost to finish a basement in Northern Virginia?
Most basement remodels in our area run $35,000 to $90,000 or more. An open rec room lands at the lower end, while a full finish with a bathroom, wet bar, or legal egress bedroom lands at the higher end. Square footage, plumbing, waterproofing, and finish level all move the number, so we price every project after a walkthrough.
How long does a basement remodel take?
A typical finished basement takes 6 to 10 weeks from the start of construction. Adding a bathroom, an egress bedroom, or custom built-ins extends the schedule, and permitting adds time before work begins. We give you a realistic timeline during your consultation.
Do I need a permit to finish my basement?
In almost all cases, yes. Finishing a basement, especially when adding a bathroom, bedroom, or electrical circuits, requires permits and inspections. We handle the permitting process for you as part of the project.
Can I add a bathroom or a legal bedroom in my basement?
Yes to both. We install below-grade plumbing for full or half bathrooms, including a sewage ejector pump when the layout calls for one. For a legal bedroom, we cut in code-compliant egress windows so the room is safe and permittable.
How do you prevent basement moisture problems?
We assess for moisture before framing anything. Depending on conditions, that can mean grading and drainage improvements, interior waterproofing, sealed vapor barriers, and moisture-resistant materials, so your finished space stays dry and healthy for the long haul.
Is BAC licensed and insured?
Yes. Building America Construction is fully licensed and insured for permitted basement work throughout Northern Virginia. With 15+ years in business and 300+ completed projects, we are credentialed to pull permits and pass inspections.
