Testing & Assessment
Mold Inspection & Testing in Daly City, 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
December is not January. Why is it the wettest call on this bluff?
Because this gauge peaks early. December puts four inches onto fill over dune sand a hillside already wants to move. A January cell inland is a different climate. Do not copy a Diablo Valley January diagnosis onto Mussel Rock.
The rain gauge was quiet. Why is the siding still wet?
Fog drip. The Pacific wets this bluff on days the gauge records a trace. Fill over dune sand then holds that moisture against a 1965 plate. Looking at a downtown total will not tell you whether the fog has already done the month's work.
Is the landslide the reason Westlake slabs crack after a December cell?
Partly. The bluff moves, and the fill was dumped over sand. December rain is the pulse that shows the movement as a crack or a wet joint. A roof inspection will not see a hillside that is still going downhill.
