Even in the desert, mold grows after slow leaks, evaporative-cooler drips, and monsoon water intrusion. The EPA notes that fixing the moisture source is the key to mold control, and suggests professional help for areas larger than about 10 square feet.
Frequently asked questions
Can I clean small mold spots myself?
The EPA says small areas (under about 10 sq ft) can often be cleaned by a homeowner; see its guidance before starting.
Where mold hides in Tucson homes
- Under sinks and behind dishwashers after slow leaks
- In ceilings below swamp coolers. See cooler leaks and mold.
- Around AC air handlers and condensate drains
- Behind baseboards after a slab leak
- After monsoon water enters through doors or roofs
How remediation usually works
- Find and fix the water source.
- Contain the area so spores do not spread.
- Remove materials that cannot be cleaned, such as wet drywall or insulation.
- Clean and dry remaining surfaces.
- Confirm the area is dry before rebuilding.
The EPA notes that small areas can often be cleaned by homeowners, while larger areas or HVAC contamination may call for a professional.
Common questions
Do I need mold testing?
Not always. If you can see or smell mold, the priority is fixing the water source and cleaning. Ask a contractor whether testing would change the plan.
Will painting over mold fix it?
No. Mold under paint can keep growing. Fix the moisture and remove or clean the material.
