Mold Testing Services in Granite City, IL

Granite City basements have been damp longer than most of us have been alive. Century-old foundations, high water tables near the river bottoms, and decades of deferred drainage work mean a huge share of the city's housing has some level of chronic basement moisture, and chronic moisture eventually grows something.

The classic Granite City call: a family buys or inherits an older two story, and the basement has paneling on the walls and carpet remnants on the floor, someone's rec room project from the 70s. It smells like every old basement, which is to say nobody thinks anything of it. Behind that paneling we found widespread growth on the original plaster, active for years, with air samples showing elevated spore counts making it to the first floor. The paneling came out, the defined area was remediated, and the retest cleared.

Our inspection is built for old, chronically damp structures. We take moisture readings on foundation walls and floors, check behind finishes where access allows, pull air samples against an outdoor baseline, and sample visible growth for identification. An accredited lab does the analysis, and the report separates cosmetic staining from active problems, because in hundred-year-old basements those are different things.

Test when a basement smell gets stronger, after sewer backups or flooding, before finishing or storing anything valuable down there, when respiratory symptoms track with the house, and before buying any older Granite City home.

We're NORMI certified, we know this housing stock, and we give straight answers either way.
