Fast scheduling and lab turnaround

Calls are answered 24/7 and routed to a tester near El Cerrito. Standard lab results usually come back in two to three business days, with rush options available.

Licensed, insured, independent testers

Insurance, licensing where required, and accredited lab partners are the baseline we look for in every independent tester.

What Gets Done

Sampling Options Matched to Your Situation

The right test depends on what you're trying to prove. These are the common options.

Indoor air sampling

A pump draws a measured volume of air, often about 15 liters per minute for five to ten minutes, through a spore trap cassette. The lab counts and identifies spores per cubic meter.

Surface tape-lift and swab samples

Clear tape or a sterile swab picks up material from a suspicious stain so the lab can confirm whether it's mold and which genus it is.

Wall cavity sampling

A small port lets the tester sample air inside a wall without opening it, which is useful when you suspect growth behind finished drywall after a leak.

Post-remediation clearance testing

Clearance testing gives you proof the remediation worked before walls are closed up or tenants move back in.

Real estate and landlord documentation

Lab reports with chain-of-custody records give buyers, sellers, tenants, and landlords objective evidence instead of competing opinions.

Testing Stories From Recent Callers

Here's what some recent callers shared.

Affordable Mold Testing solutions in El Cerrito, CA
My landlord kept saying the spots in my bedroom were just dirt. The lab confirmed two types of mold on the wall, and the air sample was well above outdoor levels. That report got the repair done.
BCBrianna C.Renter · El Cerrito, CA
I wanted proof the remediation actually worked. The clearance air samples came back lower than the outdoor control, and I finally felt comfortable moving my kids back into the basement.
GEGrant E.Homeowner · El Cerrito, CA
We were selling and the buyer asked about a past leak. A quick cavity sample plus air testing showed nothing unusual, and the deal closed on time.
YRYvonne R.Home Seller · El Cerrito, CA
He walked me through every number on the report instead of just emailing a PDF. Knowing what was normal versus elevated made the whole thing less stressful.

FAQ

Mold Testing Questions, Answered

Air tests tell you what you're breathing. Surface tests tell you what a visible stain actually is.

Without an outdoor baseline, indoor numbers have nothing to be compared against. It's what makes the results meaningful.

Typically a few business days, with faster rush options when you're facing a closing date or move-in deadline.

Not very. Petri-dish kits grow mold in nearly every home, which tells you little. Professional sampling measures volume and compares indoor to outdoor air.

No official threshold exists. Testers look at how indoor counts and types compare to outdoor air on the same day.

ERMI analyzes settled dust using DNA methods to identify mold species. It's sometimes used in health-related investigations, though most residential decisions rely on air and surface sampling.
