Testing & Assessment
Mold Inspection & Testing in Santa Rosa, CA
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
Is December just a big rain, or is the creek doing extra work?
Both. 6.47 inches is already a large share of 31.53. The extra work is creek alluvium and a Russian River table that does not drop when the storm pauses. A dry-looking street on the valley floor can still have a wet crawlspace because those are two different water bodies.
Coffey Park was rebuilt. Are those houses dry by design?
They are new slabs on the same alluvium. Rebuild fixes the structure, not the December table or the creek. Older crawlspaces fail from below; new slabs fail at grade and at the pad edge. The fire changed the stock, not the hydrology.
Rohnert Park is seven miles south. Same valley?
Same valley climate, different creek position and a younger grid. This city is Santa Rosa Creek, a 1980 mix, and a 6.47-inch December. Use the creek alluvium and the mixed stock, not a Sonoma Valley label.
