Washington, D.C. contains over 40,000 rowhouses built between 1870 and 1950, most concentrated in Capitol Hill, Shaw, and Columbia Heights. These attached homes share party walls constructed from porous brick with minimal moisture barriers. When one unit experiences water damage from leaking pipes or foundation seepage, moisture migrates through shared walls into adjacent properties. Basements often feature dirt floors or thin concrete slabs poured directly over clay soil. Summer humidity condenses on cool foundation walls, creating surface moisture that attracts water bugs. Cramped crawl spaces beneath front stoops trap moisture and provide protected harborage for sewer roaches. The architectural charm that defines D.C. neighborhoods also creates structural vulnerabilities that support moisture-related pest infestations.
