What to Do in the First 24 Hours After Water Damage

The first 24 hours after water damage occurs are the most important. Mold can begin developing within 24 to 48 hours in a warm, damp environment, and the longer materials stay wet, the more likely they are to need full replacement rather than repair.

Step 1: Ensure Safety First. If there is any risk of electrical hazard — standing water near outlets, a wet ceiling near light fixtures, or visible sparking — do not enter the area. Shut off electricity at the breaker if you can do so without stepping into water.

Step 2: Stop the Water Source. If the damage is from a plumbing issue, locate and shut off the main water valve or the shutoff valve for the specific fixture involved.

Step 3: Document Everything. Before you move anything or begin cleanup, take clear photos and videos of the damage. This documentation is valuable for insurance claims and for restoration professionals assessing the scope of work.

Step 4: Remove Standing Water If Safe. A wet/dry shop vacuum can help with small amounts of water, but significant standing water requires professional extraction equipment.

Step 5: Move Valuables and Furniture. Relocate furniture, electronics, and valuables away from the affected area to a dry space, if it is safe to do so.

Step 6: Call a Restoration Professional. The sooner professional extraction and drying begins, the lower your risk of secondary damage like mold growth, warped flooring, or structural issues.

Avoid using regular household fans as your only drying method for anything beyond a very small, shallow spill — they simply aren't powerful enough to dry saturated materials or meaningfully reduce ambient humidity in a room.
