Testing & Assessment
Mold Inspection & Testing in Rochester, MN
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
There is a Rochester in New York. Do we share a moisture story?
We share a name and a June-or-July wet month, not a ground. That city sits on glacial till along the Genesee and Lake Ontario, and lake-effect snowmelt is its spring event. This one sits on Driftless karst along the Zumbro, and the water moves through limestone joints. The two pages are written so a swap test cannot confuse them.
A sink in the yard keeps coming back. On this limestone?
Treat it as karst until proven otherwise. Residual clay over Decorah and Galena can collapse where water is concentrated, and filling the hole without finding the downspout or the leaking line just hides the next drop. A 1989 house is not too new for that.
No stream is on the lot. After June storms the basement is wet. Is that the rock?
Very likely. Joints are the streams here. Rain that left the surface a block upslope can travel the limestone and exit at a footing, so a dry yard is the expected surface, not evidence that the path is empty. A moisture meter on the wall tells you whether you are looking at that joint or at a plumbing fault.
