Mold remediation built for Shaw
If you're in a Shaw rowhouse, you're in one of DC's most historically significant Black neighbourhoods, with homes mostly built from the 1880s through the 1900s on the same party-wall, no-waterproofing-membrane construction seen across the city's older core. In parts of Shaw, decades of deferred maintenance mean some foundations are only now getting their first real look — so a moisture problem surfacing now isn't a sign you've done anything wrong.
Shaw has seen heavy new construction and renovation over the past 15 years, and a lot of it involves digging out basements to add square footage. If your neighbour is doing that kind of excavation next to a 130-year-old shared foundation wall, it can open new water paths into your side, even though the work isn't happening on your property at all.
Like Logan Circle and Shaw's other combined-sewer-era neighbours, a hard summer storm can push contaminated (Category 3) water into your basement, not just rain — it's a real and recurring pattern here, not a rare event.
Common mold types in Shaw
- Stachybotrys chartarum (deferred-maintenance foundations with chronic seepage)
- Chaetomium (older masonry and framing with long-standing moisture)
- Penicillium/Aspergillus (basement excavation/renovation-disturbed party walls)
- Cladosporium (general background growth in humid summer conditions)
