After the bulk water is extracted, the loud part begins: air movers + dehumidifiers running 24/7 for what feels like forever. Homeowners ask, every time: when can we turn these off?
The IICRC dry standard
The Institute of Inspection, Cleaning and Restoration Certification (IICRC) sets the standards every reputable restoration company follows. The standard isn't a fixed number of days — it's a moisture-content target.
- Wood structures: under 16% moisture content (often under 12% for hardwood floors).
- Drywall: under 1% moisture content (using specialized meters that read into the material).
- Concrete: under 4% moisture content.
- Carpet: dry to touch + relative humidity in the room under 50%.
Why daily monitoring matters
We don't guess at timeline. Every day, we measure moisture content at the same locations and log the readings. The pattern of decline tells us how the drying is progressing — and when target is reached.
If readings plateau (stop declining), we adjust: add equipment, change positioning, open additional cavities, or address a hidden moisture source. Without daily monitoring, you can't know when to stop or whether to add equipment.
Typical timelines by loss type
- Single-room Cat-1 burst pipe: 2-4 days drying.
- Multi-room Cat-1: 3-6 days.
- Cat-2 with selective demolition: 4-7 days.
- Cat-3 sewage event after demolition: 5-10 days.
- Crawlspace post-flood: 7-14 days (low air movement is challenging).
Why air movers AND dehumidifiers
They do different jobs. Air movers force evaporation from wet surfaces by moving air across them. Dehumidifiers pull the resulting humid air out of the room as condensate. Without dehumidifiers, the air movers just saturate the room's humidity until evaporation stops. Without air movers, dehumidifiers can't pull moisture out of materials fast enough.
The right ratio of equipment depends on the volume of wet material, the air space, and the temperature. We calculate this on every job using IICRC formulas — not guesswork.
The electricity question
Yes, drying equipment uses meaningful electricity — usually $5-15/day for a typical residential setup. That's a covered cost on most insurance claims; we provide the documentation. The alternative (incomplete drying + future mold remediation) is far more expensive.
