Swab Testing

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

The Arroyo Seco and the smaller drainage channels that feed into it maintain elevated soil moisture in adjacent residential neighborhoods throughout the year, not just during active rainfall. Properties within a few blocks of the arroyo experience higher groundwater and soil moisture levels than comparable homes further from the corridor, and this moisture translates into elevated crawl space humidity and foundation wall pressure in the older homes that dominate this part of Pasadena. During significant rain events, the arroyo channels concentrate and move large volumes of water that recharge surrounding soils rapidly, creating sudden increases in groundwater that can overwhelm drainage systems in adjacent properties. The combination of arroyo proximity and Craftsman-era construction — with its original wood foundations and crawl spaces — makes properties in this corridor a priority for thorough mold assessment.

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