A locally owned mold inspection company built on independence.
Precision Mold Group is a West Covina inspection and testing company. We are not a remediation contractor — and that is deliberate. Because we don't profit from removal work, our findings are unbiased, and our reports are trusted by homeowners, real estate agents, and property managers throughout the area.
Licensed & Insured
We carry the licensing and insurance needed to work in California residential and commercial properties.
Certified Inspectors
Our team is trained to standards from IICRC, ACAC, and InterNACHI, and stays current on EPA and CDC guidance.
Independent Laboratory
All air and surface samples go to an accredited third-party lab — we don't process our own results.
Clear, Detailed Reports
Written to be understood, with photographs, moisture readings, lab data, and specific next steps.
No Remediation Upsell
We test only. That protects you from the conflict of interest common in this industry.
Responsive & Local
Based in West Covina with 24-hour availability Sunday through Thursday for urgent inspections.
Built for the way West Covina lives.
West Covina's climate — warm days, occasional heavy winter rain, and homes built across many eras — creates conditions where hidden mold can develop quietly behind walls, under sinks, in attics, or inside HVAC systems. We started Precision Mold Group because too many homeowners were being sold remediation work they didn't need, and too few were being given the information they did.
Our answer is simple: independent inspection, independent testing, and reports written in plain language. If you don't need remediation, we'll tell you. If you do, we'll give you the data you need to hire the right specialist and, later, verify the work was done correctly.
