Testing & Assessment
Mold Inspection & Testing in Fond du Lac, WI
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
The lake looks calm. Why is the south-end cellar wet?
Calm at the surface can still be a seiche holding the south end up. Winnebago is long enough to pile water on this shore for hours, and marsh fill under the streets passes that water sideways into a 1967 basement. The river can be behaving. The lake does not have to wave to wet the fill.
A house on till inland. Is Winnebago still the diagnosis?
Usually not. Till perches June rain and sends it into original tile aimed at a lake that, when high, is a closed door. The lake is the outlet, not the source. Treating an inland cellar like a seiche cellar will have you waiting on a wind that is not in the path.
Organic fill. What does a camera in the 1967 tile usually find?
A sag where the peat compressed, so the run now ponds against the footing instead of falling to the river. Replacing that sag is the repair. A new pump in the old hole will keep fighting a line that no longer goes downhill.
