How Long Does It Take to Dry Out Water Damage?
How Long Does It Take to Dry Out Water Damage?
Honest answer: 3–5 days for most residential water damage — but the range is 2 days to 3+ weeks depending on water category, material, volume, and response speed.
What Determines Drying Time
Category 1 (clean burst pipe) dries fastest. Category 2 adds 20–30% for antimicrobial treatment. Category 3 (sewage/flood) often requires demolition. Material matters: drywall 3–5 days, hardwood 5–10 days with mat system, concrete slab 10–21 days, carpet (pad removed) 1–3 days.
Response time is the biggest lever. IICRC data: extraction at 0–2 hrs = 3-day avg. At 6–12 hrs = 5–7 days. After 24 hrs = 7–14 days plus mold risk.
How We Confirm Drying Is Complete
Not by touch — by Delmhorst pin meter readings. Wood must read ≤12%, concrete ≤4%. Psychrometric readings must show humidity trending down for 24 hours. Equipment stays until thresholds are met.
Can I just use fans from the hardware store?
Consumer fans move air but do not dehumidify. Without dehumidification, mold colonizes in 24–48 hours. Commercial LGR dehumidifiers remove 100+ pints/day vs 20–30 for residential units.
Do I have to be home while drying equipment runs?
No — we monitor remotely with humidity loggers and check in daily.
