Mold Testing in Philadelphia

Mold Testing & Removal serves Philadelphia and the surrounding communities from our office on Chestnut Street in Old City. The city’s older housing stock gives it real character and its own moisture challenges. Row homes share party walls, basements often sit below grade where dampness collects, and plaster, brick, and aging roofs move and hold water differently than newer construction.

Philadelphia housing is mostly pre 1940 and each era has its own signature problems. The brick row homes across Fishtown, Northern Liberties, Point Breeze, and South Philly usually sit over stone foundation basements that were never fully waterproofed. The Center City townhouses and the trinities in Society Hill and Queen Village have box gutters, party walls, and small below grade cellars that hold humidity year round. Manayunk and Roxborough add stone foundations on hills, where lateral water intrusion is the constant enemy. Chestnut Hill and Mount Airy Victorians have three floors of aging plaster and lath on top of large stone or brick basements. West Philadelphia twins and University City student rentals mix a century old envelope with hard use and deferred maintenance. What these homes share is a moisture story: humid summers with no central AC in older stock, seasonal party wall movement, roof water working through box gutters and shared walls, and basements that were designed to be damp.

Our local team understands these homes and inspects them with that history in mind. We look at basements, shared walls, upper floor bathrooms, box gutters, and any area touched by a past roof or gutter problem, test the indoor air quality where symptoms or musty odors suggest hidden growth, and give you a clear written read on where moisture is coming from and what it will take to fix it.
