Mold testing in Trenton: what to know
Trenton's historic housing stock — primarily 1890s–1930s brick row and twin houses — has aging masonry foundations and plumbing that make basement and lower-floor mold a persistent issue throughout the older neighbourhoods.
The Delaware River floodplain borders Trenton — properties in flood-prone areas near Lamberton Street and the Chambersburg section have recurring flooding risk during high-water events.

How we handle mold testing in Trenton
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.
