What Causes Water Damage in Phoenix Homes

1. AC condensate overflow: attic air handlers run nonstop in summer; clogged drain lines overflow into ceilings.
2. Water heaters and hard water: the City of Phoenix 2025 Water Quality Report lists hardness of roughly 10 to 17.6 grains per gallon, and scale shortens tank and valve life.
3. Slab leaks: copper lines under concrete foundations fail out of sight.
4. Polybutylene pipe: gray supply pipe stamped “PB” or “Qest,” installed in homes built roughly 1978 to 1995, tends to fail suddenly.
5. Monsoon roof leaks: parapets, scuppers, tile underlayment and old cooler openings.
6. Swamp cooler leaks: a stuck float or cracked pan on a roof-mounted evaporative cooler.
7. Supply lines and appliances: washing machine hoses, dishwasher and ice-maker lines, toilet supply lines.
8. Flash flooding: homes near washes and in the foothills can take in floodwater, which is Category 3.
9. Freezes: rare, but one hard-freeze night can split pipes in attics, on exterior walls and at backflow preventers.

Whatever the cause, the response is the same: stop the water, document it, and dry it properly. See our services and typical costs.
