Mold inspection in Rahway, New Jersey
Most mould in Rahway homes is found by smell before it is found by sight, because the majority of it grows where nobody is looking.
Why Rahway housing holds moisture
The Rahway River has a documented history of coming out of its banks, and the neighbourhoods along it have taken water repeatedly — Irene in 2011, Ida in 2021, and a number of ordinary nor’easters in between. Away from the flood zone the housing is a mix of pre-war frame homes and postwar infill, both with full basements. Two very different situations end up looking identical on a Tuesday morning: a river that rose, or a supply line that let go behind a wall.
The moisture matters more than the species
The EPA does not recommend routine sampling to identify what is growing, because the recommended action does not change based on the answer: remove the growth, and fix the water feeding it. An inspection that maps moisture is generally more useful than a test that names a species.
Where a lab report does earn its cost is when you need documentation rather than information — a sale, a landlord dispute, or a claim where somebody else will read the file.
Where it hides in Union County homes
- Behind panelling in a basement finished decades after the house was built
- Under carpet laid directly over a concrete slab floor
- Inside the wall behind a laundry connection
- Above a ceiling below a second-floor bathroom
- In the joist bay a central air condensate line runs through
- In the shared basement of a two- or three-family house, which nobody inspects
It usually starts with water
A basement that took water and was dried with a couple of fans, a supply line that seeped behind a wall for a season, a foundation that gets wet a few times a year and dries slowly — each leaves material damp out of sight.
