What does a mold inspection include?
A mold inspection is a hands-on investigation that locates mold growth, measures moisture in the surrounding materials and identifies the water source. Lab testing is one possible part of it, not the whole job. The most useful tools are a moisture meter, a thermal camera and an inspector who knows where water hides in East Valley homes.
When to get a mold inspection
- You smell a musty odor but can't see mold (see finding the source of a musty smell)
- You had a leak or water damage that wasn't professionally dried
- You see spotting, staining or bubbling paint
- Allergy-like symptoms improve when you leave the house
- You're buying or selling a home with a history of leaks
- You want to confirm remediation worked
What we check
- History. We ask about past leaks, slab leaks, roof leaks, AC overflows and remodels.
- Visual inspection of rooms, closets, under sinks, around tubs and showers, the AC closet and the attic.
- Moisture readings on walls, floors, baseboards and ceilings to find wet materials.
- Thermal imaging to spot cool, damp areas inside walls and ceilings.
- HVAC check around the air handler, drain pan and condensate line.
- Sampling, when it answers a real question.
Mold testing: when it helps and when it doesn't
If you can see mold, testing usually isn't needed to decide to remove it. The EPA makes the same point: visible growth should be removed whatever the species. Testing earns its cost in a few cases:
- Air sampling comparing indoor air to outdoor air when mold is suspected but hidden
- Surface sampling to confirm whether a stain is mold
- Clearance testing after remediation, ideally by an independent tester
- Documentation for insurance, landlords or real estate deals
All indoor air contains some mold spores. A result only means something when compared with an outdoor sample taken at the same time.
After the inspection
You get a written summary with photos, moisture readings, the likely water source and a recommended scope. If remediation is needed, we explain containment, removal and drying. If the problem is a small surface area you can safely clean yourself, we tell you that too.
Visible dark growth on drywall or wood usually leads to black mold removal. Mold around the air handler or vents points to HVAC and attic mold work.
Arizona has no state mold inspector license
Arizona doesn't license mold inspectors or mold remediators specifically. That makes it more important to check training and independence. Look for IICRC or similar certifications, and be cautious of anyone who inspects, tests and remediates without explaining how they avoid a conflict of interest.
