Yes. Home Environmental Quality Engineering holds DOSH Certified Asbestos Consultancy, CDPH lead certification, certified mold inspection, HAZWOPER, and building inspector credentials. Testing is performed to regulatory protocols with accredited laboratory analysis.

No — and that's intentional. We are an independent testing and consulting firm. Because we never profit from cleanup work, our results are unbiased and trusted by insurers, agencies, contractors, and courts.

Tell us what's happening — a renovation, a leak, an odor, an escrow deadline — and we'll tell you honestly which testing applies and which doesn't. The consultation is free, and we routinely advise people out of testing they don't need.

Yes. Our reports are independent, laboratory-backed, and written to support insurance claims, real estate transactions, and regulatory compliance.

We regularly work on escrow timelines. Call us with your closing date and we'll tell you immediately whether it's achievable — rush lab options usually make it possible.

Smoke can penetrate homes far from the fire line. We test surfaces for soot, char, and ash and measure residual particulates — documentation that also supports insurance claims.

Yes — bacteria testing is our one flat-range service, priced by the number of samples and areas involved. All other services are quoted per project because scope varies so much.
