Phoenix is dry, but mold still grows where water collects. Air conditioner leaks, evaporative coolers, monsoon roof leaks and slab leaks all create damp spots, and because the outside air is dry, many people do not expect mold until they smell it.
Sifixit is a free referral service. Call the number on this page and you will be connected with an independent mold removal provider that serves the Phoenix area, where one is available for your ZIP code. Calling costs nothing and you are never obliged to hire anyone.
Why mold grows in Phoenix
Air conditioner leaks
Air conditioners run most of the year. Clogged drain lines and rusted pans can leak into ceilings and walls.
Evaporative coolers
Swamp coolers add moisture to indoor air and can leak onto roofs and into ceilings if not maintained.
Monsoon roof leaks
Summer monsoon storms bring sudden heavy rain that finds weak spots in flat and tile roofs.
Slab and plumbing leaks
Leaks under slabs and inside walls can feed hidden mold for months.

Permits and local rules
Cleanup itself does not usually need a permit, but the repairs that follow often do. Inside the city of Phoenix, larger drywall, electrical and plumbing repairs can require permits from the City of Phoenix Planning and Development Department. Homes in other cities, such as Scottsdale, Tempe or Mesa, follow the rules of that city or county.
In Arizona, contractors must be licensed by the Arizona Registrar of Contractors, and you can check a license online.
Seasonal risks in Phoenix
If anyone in the home has asthma, a weak immune system or breathing problems, keep them away from the moldy area and speak to a doctor about any symptoms.
- July to September: monsoon storms bring roof leaks.
- Summer: air conditioners run hard and drain lines clog.
- Spring: a good time to service coolers and roofs.
- All year: slab and plumbing leaks can feed hidden mold.
Be prepared
- Have the air conditioner drain line and pan checked

Phoenix questions
Can mold grow in a dry climate like Phoenix?

Does Arizona license mold removal companies?
Arizona does not have a separate mold license. Contractors doing repair work must be licensed by the Arizona Registrar of Contractors.
I rent. Who fixes mold?
Arizona law requires landlords to keep rentals fit to live in. Tell your landlord about leaks and mold in writing.
