Testing & Assessment
Mold Inspection & Testing in Bellevue, WA
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
Water is emerging from the hillside itself. What is that?
Yes — it is groundwater surfacing, not runoff. Layers of dense till stop water descending, so it slides along the top of that layer until the hillside cuts across it and it emerges as a seep. The outlet has no relationship to anything visible above it, which is why it appears out of nowhere.
What does peat under the low ground mean for a building?
Settlement rather than water entry. Peat is organic and compressible, so it consolidates under load and does so unevenly, which distorts what sits on it. It is a different failure mode from the hillside drainage problems and needs a different response.
The buried wall is damp and the open one is not. Is that a fault?
That is the expected result rather than a fault. Only the buried side is holding back saturated earth and taking pressure from it; the open side is a wall with weather on the other face. One damp wall in a daylight lower floor points to the earth outside it.
