Testing & Assessment
Mold Inspection & Testing in Rochester, MN
An assessor determines whether mold is present, identifies where it is growing, and measures how far it has spread — before any remediation quote is issued. 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.
Local contractors · findings documented for your claim
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
Winter opened a crack in the basement wall. Does June water find it?
That is the usual sequence here. Deep frost works a 1989-median wall through the winter, and June, at 5.35 inches of a 36.96 inch year, is the first heavy water to reach the opening. On Decorah and Galena the rain does not sheet across the yard to get there. It drops into joints and arrives at the footing with head behind it, so a crack that looked cosmetic in March passes water in June. Close it before the wet month rather than after.
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.
