Crawl Space to Basement Conversionsin the DMV
Turn Your Damp Crawl Space Into a Full-Height Basement
Stop wasting space under your home. We excavate, underpin, and convert shallow crawl spaces into functional, dry basements that add square footage and structural value.
Beyond Just "Digging Out"
Safely Expanding Your Home From the Ground Down
A conversion is a major structural lift for your house. We take the cramped, dark area under your floor joists and transform it into a full-height, livable basement. The process involves phased excavation, underpinning your existing foundation, and integrated drainage.
In older Alexandria or DC homes, crawl spaces are usually dirt-floored magnets for moisture and mold. Digging down creates space for a gym or suite and also reinforces an aging foundation while fixing humidity issues at the source.
Need More Room?
You get a full floor of new living space without losing an inch of your yard.
Dry Out the House
Converting to a basement usually kills the "old house smell" by replacing damp dirt with sealed concrete.
Fix the Foundation
Most conversions include underpinning, which actually makes your home's footprint more stable than the day it was built.
Property Value
A basement with 8-foot ceilings is a massive selling point in the DMV market.

Crawl Space Conversion FAQs
Common Questions About Digging Down H3: What You Need to Know Before the First Shovel Hits the Dirt
Q: Is it actually safe to dig under my house?
If it’s done right, yes. We use phased excavation and temporary structural shoring. Your house stays supported throughout the entire dig.
Q: How long is my house going to be a construction zone?
These aren’t overnight jobs. Expect several weeks or more depending on the size of the footprint and how deep we’re going.
Q: Will I actually see a return on investment?
In the DC metro area, square footage is everything. Adding a basement is often more cost-effective than a traditional “pop-top” or side addition.
Q: Do I really need a new drainage system?
Always. If you’re digging deeper, you’re closer to the water table. We build the waterproofing into the foundation so you never have to worry about floods.
Q: Can I finance a project this big?
Yes. Most homeowners do. We have flexible plans to break the cost into manageable monthly payments.
STILL HAVE QUESTIONS?
Converting a crawl space is a big decision. If you’re unsure whether your foundation can handle it or if the math makes sense, our specialists can give you a straight answer on feasibility.
