HVAC Mold Testing

Same-day and next-day appointments are usually available across our Pomona service area, with 24/7 emergency response for active leaks, recent water damage, or urgent real estate timelines. Standard scheduling runs 1 to 3 business days depending on availability.

Our certified mold inspectors assess bathrooms, kitchens, laundry rooms, basements, attics, crawl spaces, HVAC components, and any area showing signs of past or current water issues. Thermal imaging and moisture meters identify hidden moisture behind walls and under floors.

In Pomona's pre-war and mid-century residential properties, the three most consistent mold pathways we identify are crawl space ground moisture accumulation, aging plumbing failures behind walls, and deteriorated exterior building envelope materials that allow water intrusion during rain events. Crawl spaces in the city's older raised-foundation homes frequently lack functional vapor barriers — either because they were never installed or because original materials have degraded over decades — which allows ground moisture from the San Gabriel Valley's soil to migrate continuously into the foundation space and adjacent structural framing. Original galvanized plumbing in these properties has in many cases exceeded its 50 to 70-year service life and develops pinhole leaks inside wall cavities that sustain mold-supporting moisture without producing visible water damage at surfaces. The combination of these factors in a single structure creates layered moisture risk that requires systematic, tool-assisted inspection to fully characterize.

Pricing varies based on the size of the property, the scope of testing required, and whether any lab work is included. Most residential mold inspections in Pomona fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
