- Stop the moisture source and stabilize the affected area1 hour
What you produce: A dry, safe environment where mold growth has halted and no further water damage occurs while you plan the next moves. Why it matters: Every hour the area stays wet, mold colonizes deeper into building materials. Stopping the water now caps the scope before anyone writes a quote.
Locate and shut off the water supply.
- If the source is a burst pipe, a leaking appliance, or a failed fixture, close the nearest shutoff valve (under the sink, behind the toilet, at the water heater) or the home’s main water shutoff at the meter or well tank.
- If the source is roof leakage or groundwater intrusion (rain, flood, rising water table), stop the water at the entry point — tarp the roof, sandbag the doorway, or trench away from the foundation. Do not enter standing water if the power is on.
- Photograph the source and any visible water stains before you touch anything.
Move furniture, rugs, and valuables out of the affected zone.
- Carry fabric items (upholstered furniture, drapes, area rugs, clothing) to a dry room or outdoors on a clean tarp. Wet fabric harbors mold within 24–48 hours.
- Move electronics, documents, art, and irreplaceable items to a secure dry area. Photograph the position of each item before moving it for insurance records.
- Do not slide furniture across wet carpet — lift it. Do not stack wet rugs on top of each other.
Set up drying equipment only if it is safe to use electricity in the area.
- Plug dehumidifiers and fans into a GFCI-protected outlet on a dry surface. If the floor is wet, run an extension cord from a dry circuit.
- Aim fans at wet surfaces, not directly at mold — blowing air spreads spores. Dehumidifiers reduce ambient humidity below 60 %, which slows mold growth.
- If standing water is deeper than ¼″ or the ceiling is sagging from water weight, do not enter the room. Call a water-extraction service that will perform emergency drying only (no remediation contract).
