Testing & Assessment
Mold Inspection & Testing in Shoreline, 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.
No obligation: the assessment comes before any scope
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
It rarely rains hard here. Why is the crawl space full of water all winter?
It rarely stops. The wet season here is steady drizzle from November to March rather than heavy storms, and under this suburb is a layer of glacial hardpan that water cannot pass. The ground above it fills in November and has no way to drain, so it stays saturated as long as the drizzle keeps arriving, which is until spring. A crawl space on that ground is over standing water for five months because none of it can leave.
We are on the edge of one of the ravines. Does that help or hurt?
It depends which side of the house faces it. The ravines are cut down through the till, and the ground on either side drains sideways toward them along the top of the hardpan. A house at the ravine edge has that flow passing under it, so the crawl space is a channel all winter. A house set back on flat ground has water perched under it that goes nowhere. The ravine drains the neighborhood through the lots along it.
The north side of the house has moss on the siding. Is that just cosmetic?
It is a sign the wall never dries. A north-facing wall under trees here gets no sun from October to April and is wetted by drizzle most days, so moss grows because the surface stays damp continuously. Behind that siding the sheathing is at the same humidity. The moss itself is harmless; the condition that grows it is what wets the wall. Letting light onto that side and keeping the siding clear changes the condition, not the symptom.
