WHAT TO DO IN THE FIRST 24 HOURS AFTER WATER DAMAGE

STEP-BY-STEP: FIRST 24 HOURS AFTER WATER DAMAGE

Hour 0-1: Safety First

Turn off electricity to all affected areas immediately. Water and electricity are a deadly combination. If you cannot safely reach your electrical panel, call your utility company or 911. Do not walk through standing water if there is any chance it is in contact with electrical outlets, appliances, or wiring.

Identify the water source and stop it if you can safely do so. Turn off the main water supply valve if the source is a burst pipe or plumbing failure. If the flooding is from an external source (storm, river), focus on safety and evacuation instead.

Assess safety hazards. Check for structural damage, sagging ceilings, or buckling floors. If the building feels unsafe, evacuate and wait for professionals. Wear rubber boots and gloves if you must walk through contaminated water.

Hour 1-4: Call for Professional Help

Call a water damage restoration company immediately. Professional response within the first few hours dramatically reduces damage and cost. Restoration companies have industrial equipment that can extract water 10-20 times faster than consumer products. Do not wait to see if the water dries on its own — it won't, and every hour of delay allows water to penetrate deeper into building materials.

Hour 1-4: Document Everything

Take extensive photos and video of all damage before any cleanup begins. Document the source of water, all affected rooms, damaged belongings, and the water level. This documentation is critical for your insurance claim. Without it, you may receive significantly less coverage.

Hour 2-6: Begin Emergency Mitigation

While waiting for professionals, you can take these steps to minimize additional damage:

• Remove furniture from standing water and place aluminum foil under furniture legs on wet carpet to prevent staining
• Move valuables, documents, and electronics to dry areas
• Mop up or wet-vac standing water if you have the equipment and it's safe to do so
• Open windows and doors for ventilation (only if outdoor humidity is lower than indoor)
• Do NOT use a regular household vacuum to remove water — this is extremely dangerous
• Do NOT turn on the HVAC system if ductwork may be wet — this can spread contamination

Hour 4-12: Contact Your Insurance Company

File your insurance claim as soon as possible. Most insurance policies require prompt notification of water damage. When you call, have the following ready: your policy number, the date and time of the incident, the source of the water, a general description of the damage, and your documentation photos/videos. Ask your insurance company about their approved restoration vendors, but know that in California you have the right to choose your own contractor.

Hour 12-24: Professional Assessment and Extraction

Once professionals arrive, they will use moisture meters and thermal imaging cameras to assess the full extent of damage (which often extends far beyond what's visible). They will begin water extraction with commercial-grade equipment and set up industrial dehumidifiers and air movers for the drying process, which typically takes 3-5 days depending on severity.

THE 24-72 HOUR TIMELINE: WHY SPEED MATTERS

COMMON MISTAKES TO AVOID

Waiting to "see if it dries." This is the most expensive mistake homeowners make. Water that seeps into wall cavities, under flooring, and into insulation will not dry on its own. By the time you notice mold or structural damage, restoration costs have multiplied.

Using newspaper to dry wet surfaces. Newspaper ink transfers to surfaces and creates additional staining that can be difficult or impossible to remove.

Ignoring "small" leaks. A slow leak under a sink or behind a wall can cause thousands of dollars in hidden damage over weeks or months. If you discover any leak, address it immediately.
