How long does water damage drying take?

For a clean-water loss, drying usually takes three to five days. That is the honest short answer for most Hollywood jobs — a burst supply line or an AC overflow caught early, dried with the right equipment, verified by meter. The longer answer is that the material decides: drywall gives up water in days, while CBS block walls, concrete slabs and hardwood — the Class 4 materials in the IICRC S500 standard — hold water deep inside and can take a week or more. This page breaks the timeline down by material and by what slows a job down, so you can tell a normal schedule from a stalled one.

Timeline by material

These ranges assume the equipment is sized right and running around the clock. They also assume the water was Category 1 or 2. Category 3 changes the schedule entirely: porous materials it touched are removed rather than dried, and the clock becomes removal plus treatment plus rebuild, not drying.

Class is the word that predicts your timeline

Technicians rate a loss by class under the IICRC S500 standard, maintained by the IICRC. Class 1 is a small amount of water in a small area. Class 2 is a whole room with water wicked up the walls. Class 3 has water coming from overhead — saturated ceilings and walls. Class 4 is the deep one: water bound inside materials like hardwood, plaster, concrete and block that need longer, more specialized drying. Hollywood's slab-and-block construction means Class 4 shows up here far more often than the national average job, and Class 4 is why a Hollywood drying job that "should" take four days on a generic internet chart legitimately takes eight. The mechanics — how block cores and slabs release water, and how readings prove progress — are explained in structural drying for CBS block and slabs.

What slows a job down

• A late start. Water that sat for two days has wicked further and soaked deeper. The first 72 hours timeline shows how the job grows by the day.
• Open windows. South Florida outdoor air is humid most mornings — climate normals from NOAA put morning relative humidity around 80 percent in this region — so an open house fights its own dehumidifiers.
• Equipment switched off. Drying gear is built to run 24 hours a day. Every night it is unplugged for the noise, the clock stretches. Expect a higher power bill for the drying days and keep it; the equipment log shows run time if an adjuster asks.
• Hidden reservoirs. Water inside block cores, under terrazzo, and in cabinet toe-kicks keeps feeding a room after the visible materials read dry. Meters at marked points, taken daily, catch this; touch does not.
• Category 3 rules. Sewage and floodwater jobs remove porous material first — no drying timeline applies to material that is being discarded, and Florida treats larger mold work as licensed remediation (the EPA's background is at epa.gov/mold).

How you know it is actually done

Drying ends on numbers, not on how the room feels. The crew compares readings at the marked wet points against a dry standard taken from an unaffected area of the same material. When the wet points match the standard, and a thermo-hygrometer confirms the room air is dry as well, the equipment comes out and the readings go into the closing file with the dated photos. That file is what the whole sequence — extraction, drying, then rebuild — hands to your insurer, as laid out in the restoration guide. Repairs after drying add their own days to weeks, depending on how much drywall, flooring and cabinetry came out and what the City of Hollywood requires in permits for the rebuild work.

One practical note while the equipment runs: for a clean-water loss it is usually fine to stay in the home, but rooms inside plastic containment are off limits, and drying gear adds real noise and heat. Sewage, floodwater or any electrical hazard is different — stay elsewhere until the crew clears the area.
