Mold and air quality testing along the Malibu coast and up the canyons, including fire rebuilds and older beach houses.
Malibu splits into two very different problems. On the beach side it is salt air, wind-driven rain against exposed elevations, and decks and crawl spaces that never fully dry. Up the canyons it is drainage: hillside runoff, retaining walls and homes built into a slope where water moves through the ground rather than off it. Rebuilt homes deserve their own attention, because a structure that went up quickly after a fire can trap construction moisture inside a tight new envelope. We check crawl spaces and under-deck areas by hand rather than assuming a newer build is clean.
Malibu homes face conditions few other areas combine: salt air and fog along the coast, steep canyon lots with drainage running toward the house, and a large number of homes that have been rebuilt or heavily repaired after wildfires. Beach houses often have decks, sliding doors and window systems that take direct weather and can leak into wall cavities. Canyon homes in areas like Point Dume, the Malibu hills and the canyons off Pacific Coast Highway can collect runoff against foundations and lower floors during winter storms. Newer construction is tight and energy efficient, which helps comfort but can trap moisture if ventilation is not balanced. We focus on window and door openings, lower levels built into slopes, crawlspaces and any area that has been exposed to water from storms or firefighting.
We work with homeowners, renters, landlords, property managers, real estate agents, buyers and sellers in Malibu. Some clients call after a leak or a musty smell, others need documentation for a landlord, an HOA or an insurance claim, and many book before closing on a home. Whatever the reason, you get an independent inspector, honest answers and a clear written report.
Yes. Water that entered the structure from storms or firefighting can leave materials wet inside walls and under floors. We use moisture readings to find affected areas and recommend sampling only where it will answer a real question.
Yes. Malibu is within our regular service area, including beachfront homes and canyon properties. We schedule visits around your access needs, including gated roads.
No. We are a testing-only company, so our findings stay unbiased. If remediation is needed, our report gives you the information to get competing bids and later confirm the work with post-remediation clearance testing.
Yes. Salt air wears down window frames, door thresholds, flashing and fasteners faster than inland conditions. Over time, small gaps let wind-driven rain into the wall. We check these openings with moisture meters and look for staining or damaged trim around them.
It is a smart step. Rebuilt and heavily repaired homes can have materials that got wet during construction or storms. A pre-purchase inspection gives you independent information before the end of your contingency period.
Just Mold Testing is an independent inspection and testing company. We do not perform mold removal in Malibu or anywhere else, and we never will. The company that finds the mold should not be the company that profits from removing it.
You get a written report with the laboratory data, an explanation of what the numbers mean, and practical next steps. If remediation is needed we tell you exactly what to ask a contractor for, then we are happy to return afterwards for independent post-remediation verification.

Residential · Mold inspection with moisture readings, thermal imaging and air testing
Our inspector checked an interior wall with a moisture meter and a thermal camera, then took an outdoor control air sample on the back patio to compare with the indoor air.
