Mold & Microbial Testing in Stockton, CA

Air and surface sampling to confirm mold, identify the type, and trace it to the source.

Mold needs two things to take hold: moisture and time. A slow leak under a sink, a roof that let water in last winter, a bathroom that never quite dries — any of these can become a problem you smell before you see.

Testing tells you whether what you’re dealing with is mold, how significant it is, and where it’s coming from.

Signs it's worth testing

A persistent musty or earthy odor
Visible discoloration or growth on walls, ceilings, or grout
A history of leaks, flooding, or water damage
Worsening allergy or respiratory symptoms indoors
A real estate transaction where mold is a concern

How our mold testing works

We start by looking for the moisture source, because mold is a symptom, not the root cause. Then we collect air samples (spore traps) and surface samples (swabs or tape lifts) as the situation calls for, and compare indoor readings against an outdoor baseline. An accredited lab identifies and quantifies what’s present, and we explain whether the levels are typical, elevated, or a problem that needs remediation. Because we test rather than remediate, our findings stay objective.

Frequently asked questions

Can't I just use a store-bought mold test kit?

Those kits grow whatever lands on them and rarely tell you anything actionable. Proper air and surface sampling with lab analysis gives results you can rely on.

Why compare indoor and outdoor samples?

Mold spores exist everywhere outdoors. Comparing indoor to outdoor is how we tell "normal" from a genuine indoor problem.

Do you find where the mold is coming from?

We look for the moisture source as part of testing, since fixing that is the only way remediation lasts.

How fast can I get results?

We move quickly and will give you a specific timeframe up front when we schedule.
