Where I do mold inspections

City rowhomes with shared walls and stone foundations, plus the older neighborhoods off Market and Philadelphia Street. Wet basements are the usual story here, and there is a full page on York.

Post-war homes on small lots, a lot of them with block basements and finished rec rooms that were never waterproofed first.

Tight borough lots and older twins where downspouts dump right against the foundation.

Bigger lots, well water, and a lot of houses with crawl spaces instead of full basements. I have a page just for Dover.

Newer developments off Route 30 with finished basements, sump pumps and the occasional failed vapor barrier.

Older custom homes near the country club, usually with additions that don't drain the way the original house does.

Split levels and ranchers with crawl spaces, and attics where the bath fan vents straight into the insulation.

Developments with walkout basements built into the grade — water finds the low corner every time.

Mix of older housing stock and rentals, which means a lot of landlord and tenant inspections.

Large older homes with stone foundations, dirt-floor sections and original attic framing.

Newer construction along the north side, where a lot of what I find traces back to HVAC condensation and bath venting.

Everything from 1950s ranchers to new builds. Grading and gutters cause most of the problems I test.
