Crawl Space Encapsulation in Dupont Circle, DC

Converted Buildings, Complicated Crawl Spaces

Dupont's big rowhouses have lived many lives — single-family homes, rooming houses, embassies, condos. Every conversion left its mark below: abandoned pipes, patched floors, sections of crawl space sealed off and forgotten. When we inspect, we map the whole footprint, including the parts nobody has looked at in decades.

The Condo Question

Many Dupont rowhouses are now condos. Crawl space work in a condo building needs the HOA or condo association on board, since the space is common area. We are used to this — we document everything with photos, provide a clear written scope, and present it in a way boards can approve.

What We See Most Here

Disjointed crawl spaces from old additions. Dead plumbing lines dripping slowly for years. Vents painted shut decades ago (which actually helped). And beautiful old-growth joists worth saving — which is exactly why the moisture needs to be stopped.

Frequently Asked Questions

My building is a condo. Can you still do the work?

Yes, with association approval since crawl spaces are typically common elements. We provide the documentation boards need: photos, scope, and a written plan.

Will the work disturb tenants or neighbors?

The work is contained to the crawl space and the access path. Most residents barely notice we are there.
