Mold inspection in San Bernardino

Evaporative coolers put moisture into the air on purpose. We check the cooler, its ducting, and the rooms it serves for leaks or too much humidity. In rental properties we also check bathrooms and kitchens for ventilation problems, and roofs and ceilings after storms. How our mold inspections work.

Mold testing in San Bernardino

Air samples help show whether moisture from a cooler or a leak has led to higher indoor spore levels. For landlords and tenants, lab results offer neutral documentation. See our San Bernardino mold testing overview (air and surface sampling) and post-remediation clearance testing.

Local conditions that affect mold in San Bernardino

San Bernardino has hot, dry summers and cooler winters, with occasional heavy storms. Evaporative (swamp) coolers, still used in parts of the Inland Empire, add moisture indoors.

The area includes older homes near the city center, newer subdivisions, mountain cabins in the nearby foothills, and many rental properties.

Common moisture sources we look for

  • Evaporative cooler moisture and leaks
  • Plumbing and water heater failures
  • Storm runoff and roof leaks
  • Poor ventilation in older rentals

San Bernardino mold questions

Do swamp coolers cause mold?

They can when they leak, run constantly, or are poorly maintained, because they add moisture to the air and ducts. An inspection checks the cooler and nearby areas.

Do you work with landlords and property managers?

Yes. We inspect rental units and provide findings landlords and tenants can both use.

When to call

Signs an inspection may be useful

  • A musty or earthy odor that keeps coming back
  • Visible spots or staining on walls, ceilings, or under sinks
  • A recent leak, flood, or roof or plumbing repair
  • Peeling paint, warped baseboards, or bubbling drywall
  • You want environmental documentation of a suspected mold or moisture concern
  • Buying, selling, or renting and wanting an independent check

Finding the cause

Moisture detection and thermal imaging

Moisture meters measure how wet drywall, wood, and flooring are. Mold needs moisture, so wet materials point to where growth is likely — and to the leak or condensation behind it.

Thermal imaging shows temperature differences across a surface. Damp areas often read cooler, which helps us decide where to take moisture readings. A thermal camera does not see mold itself.

Testing

Sampling and laboratory analysis — when it helps

Testing isn't always needed. When visible growth already explains the problem, we'll tell you. Sampling is most useful when the source is hidden, you need documentation, or you want to confirm cleanup worked.

How it works

Our inspection process

  1. 1

    Call or request a quote

    Tell us about the property, what you've noticed, and any past leaks. We'll recommend the right service and schedule a visit.

  2. 2

    On-site inspection

    We walk the property, take moisture readings, and use thermal imaging on suspect areas. Accessible attics and crawl spaces are included where safe.

  3. 3

    Sampling, if useful

    If testing will help answer your question, we collect air and/or surface samples and send them to a laboratory.

  4. 4

    Results & next steps

    You receive our findings and, if sampled, the lab results — explained in plain language.

Moisture checks

Checking wood flooring for moisture

A handheld meter is positioned over wood flooring with visible surface changes. Moisture measurements are recorded alongside the visual condition of the material.

Thermal imaging

Thermal imaging inside a property

A handheld thermal camera displays temperature patterns during an interior survey. Thermal images document surface-temperature differences; they do not identify mold on their own.

Indoor conditions

Recording indoor humidity and temperature

A handheld meter displays relative humidity and air temperature inside a property. These readings document the room conditions at the time of the visit.

Documenting an exposed interior

An interior area has exposed ceiling framing, open wall sections and visible building materials. The wide view provides context for inspection observations without representing a before-and-after result.
