Testing & Assessment
Mold Inspection & Testing in San Mateo, CA
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
Most of the state peaks in February. Why does a December cell matter more on this creek?
Because this gauge's wettest month is December. The covering has had less summer to open, but the Bay fill has had a full fall of tides. A 4.54 inch December on marsh that was only covered sits in the slab from below. Waiting for a February atmospheric river will miss the month that actually leads here.
Foster City is three miles east on fill. Is a San Mateo pad the same Bay-fill job?
Foster City is a later island of fill with its own lagoon grid. This city fails as San Mateo Creek, older marsh fill, and a 1965 median. A wet pad on the flats is a creek-mouth story. Copying a lagoon-island diagnosis west will put the meter on a grid this plat does not have.
The tide is in even when the sky is clear. Can a crawl wet with no December storm?
It can. Filled marsh still connects to the Bay. A raised perimeter on that terrace can wet from below because the marsh hydrology was never removed, only paved. December's 4.54 inches then adds a storm on top of a tide that was already doing the work on San Mateo Creek.
