Mold Testing

State-certified testing that spots hidden mold—so you can act early, stay safe, and avoid costly repairs.

About

Why Mold Testing Matters

Mold isn't always visible. It hides in air vents, under floors, and inside walls. The only way to know what you're breathing—or what's spreading—is through lab-grade testing.

  • Identify mold species and spore levels
  • Detect hidden growth in "clean" areas
  • Assess the health risk to occupants
  • Decide on the right next steps
Why Mold Testing Matters

Methodology

How our mold testing works

The three sampling methods we use, chosen for what your property is showing

Sterile swabs and clear adhesive tape collect mold from visible spots on dry surfaces, giving the lab a clean sample for species identification. Suitable for walls, ceilings, baseboards, and furniture where the residue is what you're checking.

For damp or recently water-damaged areas, the sampling approach changes. Wet sampling captures live, actively growing colonies that dry methods underrepresent, which matters under flooring, behind tile, and around recent leaks.

A calibrated pump pulls a controlled volume of air through a spore trap cassette, capturing viable and non-viable spores from the breathing zone. The lab counts species and compares concentrations to outdoor levels, telling you whether your indoor air is healthy.

Checklist

Is Testing Right for You?

Mold testing is ideal if:

  • You suspect mold but can't see it
  • You've had water damage
  • Residents or tenants are reporting health symptoms
  • You're buying, selling, or managing a property
  • You need peace of mind after remediation

Still unsure? Let's talk. We'll help you decide which method suits your case best.

Testing Overview

Our Testing Methods

Techniques we use to collect accurate mold samples from air and surfaces.

1Air Testing

Collects airborne mold spores to assess air quality and detect hidden contamination.

2Tape Testing

Lifts mold samples from surfaces using clear adhesive—quick and non-destructive.

3Swab Testing

Gathers samples from damp or textured areas to identify active mold growth.

Mold inspection San Bernardino FAQ

Call For An Inspection
They can. Many older and lower-income San Bernardino homes use evaporative "swamp" coolers, which cool the air by adding moisture to it — and in a home already sealed against the heat, that extra humidity can condense in closets, ceilings, and wall cavities. If a swamp cooler is oversized, poorly drained, or run alongside air conditioning, it becomes a steady hidden moisture source that feeds mold. An inspection accounts for how the home is cooled, because the fix is often as much about humidity control as it is about any single leak.
Yes. San Bernardino's semi-rural areas, like Muscoy, include many manufactured and mobile homes, which have skirted underbellies, crawl spaces, and duct systems that differ from standard slab houses. Moisture can collect under the home and in the belly wrap out of sight, so these inspections pay special attention to the underside, tie-downs, and any additions built onto the original unit. Catching moisture in the belly and ductwork early is what keeps it from reaching the floor and wall assemblies above.
Yes, even in a dry climate. San Bernardino's summer monsoon can deliver sudden, intense downpours that overwhelm gutters and drainage and drive water into roofs, walls, and low-lying foundations. Because the surrounding climate is so dry, that water is often assumed to have evaporated when in fact it has soaked into materials where mold can start growing. After a monsoon burst that overwhelmed drainage or pushed water inside, a moisture assessment catches what the dry air hides.
Two windows stand out. Late winter and spring bring mountain runoff and snowmelt that raise soil moisture and groundwater on the valley floor, while mid-to-late summer brings monsoon bursts of sudden rain. Homes with swamp coolers or deferred-maintenance roofs and plumbing can carry moisture risk across both seasons, so a check timed to the end of either wet period tends to find problems while they're still small.
Yes. San Bernardino sits at the heart of the Inland Empire's logistics industry, and large warehouses and distribution centers can develop mold without any obvious leak. Their vast flat roofs, big interior volumes, and HVAC systems make roof-drain failures and daily condensation the main culprits, and problems often hide above suspended ceilings or in mechanical areas for months. Commercial inspection here focuses on the roof and its drainage, the HVAC system, and the concealed spaces above ceilings where moisture collects unseen.
