Frequently Asked Questions
Do I need mold testing if I don't see any visible mold?
Yes, often. Mold frequently grows behind walls, under flooring, or inside HVAC systems long before it's visible. If you're noticing odors, past water damage, or symptoms that improve when you leave the house, testing is the only way to know for sure what's actually there.
How long does a mold inspection take?
Most inspections take one to two hours on-site, depending on the size of the property and how many areas need to be assessed.
How long until I get my results?
Lab results are typically available within a few business days after samples are submitted, and we'll walk you through exactly what the report means.
Do you perform mold remediation or removal?
No. We provide testing and inspection only. That separation is the whole point: it means our findings aren't influenced by any incentive to sell follow-up work.
Do you serve my part of LA County?
