About

Built around how Los Angeles homes actually age

Los Angeles covers a lot of climates under one metro name — marine layer near the coast, dry heat inland, and everything in between. A stucco bungalow in a canyon holds moisture differently than a mid-rise near the water, and a 1960s tract home with original ductwork has different weak points than a recently renovated duplex.

We've inspected enough of the county's housing stock to know where each type tends to hide moisture: crawl spaces under raised foundations, condensation inside older HVAC runs, roof-drain issues on flat commercial roofs, and slow leaks behind bathrooms that were re-tiled once and never opened up again.

Why us

Independent by design, not by promise

Most mold companies inspect and remediate. The more they find, the more they get paid to remove — which makes every finding a little suspect. We only inspect and test, so the fee doesn't change whether the samples come back clean or not.

We treat an active leak, a health concern, a post-remediation check, and a pre-purchase walkthrough as four different jobs, each with its own approach, rather than running the same checklist regardless of what brought you to us.

Certified & experienced

Licensed inspectors with real field experience across Los Angeles County.

Modern equipment

Thermal cameras, calibrated moisture meters, and lab-verified sampling.

Clear communication

Plain-language updates throughout, not just a report at the end.

Strong reviews

Consistently rated highly by homeowners and property managers.

"We had an urgent mold concern in our apartment building and they were out within hours. The report was thorough and easy to hand straight to our board."

FAQ

Mold inspection questions, answered plainly

I think I have mold but I'm not sure. Do I need an inspection?

If there's a musty smell, a stain that wasn't there before, or someone in the house has unexplained respiratory issues, an inspection is worth it. It tells you what's there, how much, and whether it needs attention — you don't have to guess.

How much does mold testing cost in Los Angeles?

Most residential jobs with two or three air samples run in the $300–$600 range. Larger homes and commercial properties cost more depending on the number of samples needed, and you'll see a quote before anything is collected.

Air sampling or surface sampling — which do I need?

Air sampling tells you what's floating in the air. Surface sampling tells you what's growing on something you can see. If the concern is health or air quality, go with air; if you've found a visible patch, surface. Many homes benefit from both.

Do you handle mold removal if it's found?

No — inspection and testing only. That's what keeps the findings honest. We can point you to licensed remediation contractors, but we have no financial relationship with any of them.

Will the report hold up for insurance or a real estate deal?

Yes. Reports include lab-verified results, photographs, exact sample locations, and inspector credentials — the format insurers, agents, and attorneys generally expect.

How fast can someone come out?

24/7 across our service area. For active flooding or fast-spreading visible mold, a certified inspector is usually on-site the same day.
