Testing & Assessment
Mold Inspection & Testing in Naperville, IL
An assessment establishes whether mold is present, where it is growing, and how far it extends — before anyone quotes removal. A mold inspection locates moisture and growth that a room-level look would miss, reading wall cavities, subfloor, and the areas behind finished surfaces. The result is a scope: what is affected, what has to come out, and what is driving the moisture.
Most people reach this page after noticing something rather than after something broke: a smell that returns, a stain that spreads, a room that feels damp. An inspection answers what is actually there and where the moisture comes from, which is the information every later decision depends on. Several states, Texas among them, keep assessment and remediation as separate licensed roles specifically so the party identifying the problem is not the party selling the fix. Nothing here is medical advice — if you have health questions, those are for a clinician.

Frequently asked questions
Aurora is the next city west. Why is this not the same Fox River problem?
Different river, different median. Aurora sits on the Fox with a 1987 mix of mill core and sprawl; this city sits on the West Branch of the DuPage with a 1990 planned-suburb stock on farm tile. Treating them as one suburban clay story misses both the channel and the buried drainage.
The plat for this subdivision shows no drainage across the lot. Does that settle it?
No, because the tile predates the plat. This was tile-drained farmland before it was surveyed, and the lines were never recorded as anything a developer had to draw. They still carry water, and where one was cut during construction it now discharges into whatever is beside it.
It barely rained here, but the West Branch is up. How does that reach a basement?
Through the ground, on the river's schedule rather than the street's. The West Branch collects prairie rain well upstream, so it can be running high on a day that produced almost nothing locally. A lot near the floodplain feels that as a raised water table, which is a different arrival than rain on your own roof.
