Air Testing

Same-day and next-day appointments are usually available across our San Diego 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.

San Diego's marine layer is a daily weather feature for much of the year, particularly in the coastal and hillside neighborhoods where low clouds and fog keep relative humidity at or above 80% through mid-morning. While this moisture does not typically produce the kind of direct water intrusion that rainfall does, it maintains a persistent humidity load at the building envelope level that gradually works its way into any gap in exterior cladding, roofing, or window sealing. Over months and years, this sustained moisture exposure saturates exterior wall sheathing, accumulates in poorly ventilated attic and crawl spaces, and keeps subfloor assemblies in beach-area homes damp enough to support mold growth even in the absence of any specific leak or water event. Canyon-adjacent properties experience an amplified version of this effect due to the limited airflow and persistent shade that characterize those microclimates.

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 San Diego fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
