Damp stone and block foundations
Older foundations wick ground moisture, so finished walls built against them grow mold on the back first.
Essex County is home base. Our service office is on Johnson St in Newark, so the county seat and the towns around it get the shortest drive and the most familiar houses.
Answering 24/7 from our Johnson St office in Newark
In Essex County, NJ most of our mold calls come from Newark basements that take water in heavy rain, rentals where mold sits between a tenant and an owner, and older homes with plaster walls and stone foundations. We inspect, test and remove mold across the county from our Johnson St office in Newark, with the phone answered 24/7.
Newark, the county seat, sets the pattern. About 22.6 percent of its housing was built before 1939, roughly another third between the 1940s and 1960s, and about 77 percent of its dwellings are rentals. That means old foundations, finished basements added decades later, and a lot of mold that needs documenting for two parties.
Storms add the water. On September 1, 2021 Newark took 8.41 inches of rain, its wettest day on record, and about 11 square miles of the city run on a combined sewer that can push water back up floor drains when it overloads. In the Ironbound, residents describe streets where water pools against buildings after hard rain.
