Mold remediation

Mold remediation is containing the affected area, removing moldy porous materials, HEPA-vacuuming and cleaning what remains, and fixing the moisture source. Mold always follows water, so the leak has to be found and stopped or it comes back.

How the job runs

  1. 1Inspect and find the moistureMoisture readings and a visual inspection define the affected area and its source.
  2. 2ContainPlastic containment and negative air pressure keep spores from spreading.
  3. 3Remove and cleanMoldy drywall, insulation and baseboard are removed; framing is HEPA-vacuumed and cleaned.

Mold in Arizona almost always points to a slow leak: under a sink, behind a shower, from an AC condensate line or a roof that let water in during monsoon season. Dry outdoor air doesn't stop it from growing on damp drywall inside a wall.

Arizona doesn't have a state license specifically for mold remediation, so ask the company about their training and certifications, such as IICRC, and whether they follow the IICRC S520 standard.

FAQ

Mold remediation: common questions

Can mold grow in Phoenix if it's so dry?

Yes. Outdoor air is dry, but a leak inside a wall or under a cabinet creates a damp pocket where mold grows within days. Monsoon humidity makes it more likely.

Should I test for mold first?

If you can see mold or smell it near a known leak, testing usually doesn't change the plan. Testing is more useful when you suspect hidden mold or want independent clearance after remediation.

Is bleach enough to kill mold?

Bleach doesn't reach into porous materials like drywall and can leave roots behind. Porous materials with growth are removed; hard surfaces are cleaned with detergent.
