Testing & Assessment
Mold Inspection & Testing in Seattle, WA
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
There is no leak anywhere, so why is there mold on the wall?
In this climate it is often condensation rather than a leak. Through the wet season indoor humidity stays high and exterior walls stay cool, so moisture condenses on the cool surface, particularly behind furniture on a north-facing wall where air does not move. The fix is ventilation and humidity control, not a repair.
Why does the rain here cause trouble when the totals are not extreme?
Because it is the duration that matters, not the intensity. Thirty-eight inches spread across a long grey season keeps siding, roofing and framing continuously damp, and materials that never get a dry spell degrade in ways they would not under heavier but occasional rain.
Is a daylight basement a particular risk on a Seattle hillside?
It can be. Cutting a room into a slope puts one wall permanently against uphill soil, and that soil holds water through the wet months. Without functioning perimeter drainage the wall is holding back a saturated bank, and the first sign is usually damp at the base rather than a visible flow.
