Testing & Assessment
Mold Inspection & Testing in Portland, OR
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.
Independent local crews · scoped at the property
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
Is moss on a Portland roof actually a problem or just untidy?
It is a problem, because moss holds water. A colony sitting on a shingle keeps that spot wet continuously through a season that already offers little chance to dry, and it lifts the edges of shingles as it thickens. The moss is not attacking the roof; the water it retains is.
Should a crawlspace be vented or sealed in this climate?
It depends on the house, but the winter logic is worth understanding: bringing in outside air that is already near saturation does not dry a crawlspace, it just exchanges damp air for damp air. Where a space stays wet through the season, mechanical drying and moisture control do what ventilation alone cannot.
Why do basement problems here show up in February rather than during a storm?
Because the mechanism is cumulative rather than sudden. It is not one downpour overwhelming a drain, it is soil that has been holding water since November finally reaching the point where the wall cannot resist it. The wet patch appears in midwinter because that is when the ground is at its wettest.
