Drying & repair
How long does water damage take to dry?
Updated
Short answer
With professional air movers and dehumidifiers, most clean-water losses dry in about three to five days. Dense materials like hardwood and concrete, water that sat for a long time, and humid monsoon weather can stretch that out. Moisture readings — not the calendar — decide when drying is finished.
What affects drying time
- How much water and how long it sat
- Materials: drywall and carpet dry faster than hardwood, cabinets and concrete
- Whether water reached wall cavities or under cabinets
- Indoor humidity and temperature
- How much equipment is used and whether it runs continuously
Why Arizona's dry air doesn't do it for you
Low humidity dries surfaces fast, which is why homes look dry after a day. But the back of drywall, the bottom plate of walls, cabinet bases and the slab can stay wet for weeks without equipment. That trapped water causes swelling, odor and mold.
How dry is measured
Technicians take moisture readings from unaffected materials as a 'dry standard' and compare the wet areas each day. When readings match, drying is done. The daily log is also documentation for your insurer.
