Flood lines in low-lying towns
Near the Hackensack, we find old waterlines on walls and wet insulation behind them.
Bergen County runs from tidal marsh to hill towns, and the mold work changes with it. Near the Hackensack River it is flood cleanup; elsewhere it is the attics, bathrooms and basements every older house has.

In Bergen County, NJ our mold work splits in two: flood cleanup and post-flood mold in the low-lying Meadowlands towns along the Hackensack River, and inspections, attic and basement removal everywhere else. We come from our Newark office, map the moisture first, and write a scope before anything is torn out.
During Sandy, a tidal surge up the Hackensack River overtopped the berm and flooded Moonachie and Little Ferry, with water reaching 5 feet within 45 minutes in Moonachie, and Carlstadt flooded alongside them. The old mosquito-control berms that protect Little Ferry, Moonachie and Hackensack average only about 5 feet above sea level.
That low margin means homes and businesses in those towns can flood from the river side quickly. After that kind of flooding, the cleanup standard is contaminated water, and walls need opening above the waterline.

Winter condensation darkens the underside of the roof deck in older houses.
Carpet and paneling on cool foundation walls hold moisture through the summer.

See the jobWe ask early whether the property has flooded before, because a previous flood changes where we look first: the base of every wall, the insulation behind it, and anything stored on the floor.
For homes away from the river, the visit looks like any other inspection, basement to attic, with samples only where a result would change the plan.
Yes, from the Newark service office. Call with the town and we will confirm timing.
Yes, if walls were closed before they dried. Readings and a borescope can check.
Yes. We work inside your contingency period and write a report your lawyer can use.
It is one of the most common finds, usually from winter condensation and bath fans venting into the attic.
South of Bergen County we cover Hudson County and Essex County. To the west, Passaic County shares the flood history of the Passaic River valley. The areas we serve page explains the rest.
Tell us the town and whether the property has flooded before. That tells us where to start.
