Local know-how
Wet basements and crawl spaces in Maryland
Central Maryland’s Piedmont clay soils hold water and push it against foundation walls, while Baltimore’s rowhomes often have 100-year-old brick and stone basements. Ellicott City’s repeated flash floods in 2016 and 2018 showed how quickly heavy rain can overwhelm drainage in the region.
In Montgomery and Prince George’s Counties, many 1950s–1970s homes have finished basements with block walls that are now showing cracks and seepage, and Southern Maryland homes often need crawl space work. Our partners handle all of it.
