Mold Air Quality Testing in San Jose: what's different here
Local homes
A blend of historic downtown homes, mid-century ranch-style suburbs, and modern high-rise developments. Rapid expansion during the mid-20th century defines much of the residential landscape.
What we see in San Jose
While generally warmer, seasonal rains and indoor humidity can cause mold in poorly ventilated bathrooms and kitchens. HVAC leaks are also common drivers of moisture in larger suburban homes.
Neighborhoods we visit often: Willow Glen, Almaden Valley, Silver Creek, Rose Garden, and every other part of San Jose and Santa Clara County.
When you need mold air quality testing
- A musty smell with no visible mold
- After a leak, flood or storm water got into walls, floors or a crawlspace
- Allergy or breathing symptoms that ease when you leave the home
- Before buying, renting or re-occupying a space, or after remediation (clearance testing)
What your report includes
