Why Choose Fast Mold Testing in San Jose?

San Jose Mold Inspection & Testing

Certified, data-driven inspections for homeowners, landlords, and tech campuses alike.

From historic Victorians in Willow Glen to modern condos in North San Jose and family homes in Evergreen, we provide mold testing that fits the unique needs of Silicon Valley residents and businesses. San Jose’s warm summers, foggy mornings, and aging infrastructure can create hidden mold issues especially after plumbing leaks, roof wear, or poor HVAC ventilation. Our certified inspectors combine local knowledge with advanced testing to protect your air quality and peace of mind. 

Why Choose Fast Mold Testing in San Jose?

San Jose Mold Inspection & Testing

Professional mold inspection services tailored to your needs

Visual Mold Inspection

We perform a detailed visual assessment of high-risk areas like attics, crawl spaces, and window sills.

Air Quality Testing

Our team collects air samples to measure mold spore concentration and submits them to a certified lab.

Surface Sampling

Using swab and tape lift techniques, we test suspect surfaces including HVAC registers and walls.

Moisture Mapping

Digital moisture mapping tools help locate water intrusion in walls, floors, and ceilings.

Conflict-Free Inspection

Inspections Only – Not Remediation

Unlike cheaper companies with a conflict of interest, our partners provide unbiased assessments because they don't profit from finding problems. Our only job is to make sure you get the truth, not buy services you don't need.

Texas Occupations Code 1958.155(a) prohibits licensed mold inspectors from both inspecting and cleaning/remediating. We follow this ethical standard nationwide, even where not legally required.
