Mold testing in Edison: what to know
Edison's post-war subdivision housing (1950s–1970s Cape Cods and split-levels) has crawl spaces with original 4-mil vapour barriers that have degraded over decades — crawl-space mold is extremely common in this housing vintage.
The Raritan River watershed portions of Edison have experienced repeated flooding during nor'easter storms — basement flooding and subsequent mold are recurring issues in low-lying sections.
Mold conditions in Edison
Common mold types in this area: Cladosporium (crawl space framing); Aspergillus/Penicillium (basement insulation and subfloor); Stachybotrys (chronic groundwater infiltration).

How we handle mold testing in Edison
Mold testing is not the same as a mold inspection. Testing refers specifically to the collection and laboratory analysis of air or surface samples to identify mold species and quantify spore concentrations. An inspection includes testing but also includes a visual survey, moisture mapping, and a written remediation protocol. Testing alone — without the inspection context — can produce data that is difficult to interpret correctly.
Air sampling for mold uses impaction cassettes (Air-O-Cell, Zefon BioPump) that capture particles from a calibrated air volume onto a collection medium. The cassette is analysed by a qualified analyst under microscopy. Results are reported as spores per cubic metre for each species identified. Critically, indoor samples must always be compared to an outdoor control sample taken simultaneously — outdoor spore counts vary by season, weather, and location.
