What to Do Immediately After Water Damage in Your Home

By Greene Group Construction Corp ยท Nassau & Suffolk County Restoration Experts

Water damage on ceiling and walls in Long Island home requiring immediate restoration

Water damage is one of the most stressful things a Long Island homeowner can face. Whether it's caused by a burst pipe in February, a roof leak during a summer thunderstorm, a flooded basement after heavy rain, or an appliance malfunction โ€” water moves fast, and so does the damage it causes. The decisions you make in the first few hours can dramatically affect the total damage, restoration cost, and how smoothly your insurance claim goes.

Mold can begin growing in as little as 24โ€“48 hours on wet building materials. Long Island's humid summers make this timeline even shorter. Every hour counts.

1
Ensure Safety First

Before touching anything, confirm the area is safe. Water and electricity are a dangerous combination. If water may have contacted electrical outlets, appliances, or wiring, turn off electricity to that part of the home at the breaker panel โ€” or wait for a professional to clear it. If the damage involves sewage, treat the water as contaminated and keep children and pets away.

2
Stop the Source of Water

If water is still actively flowing โ€” a burst pipe or running appliance โ€” locate your main water shutoff valve and shut it off immediately. For active roof leaks during a storm, move valuables out of the affected area and place containers to catch dripping water until the storm passes.

3
Call a Professional Restoration Company

Call Greene Group โ€” or another IICRC-certified water damage restoration contractor โ€” as quickly as possible. Professional crews arrive with industrial-grade extractors, air movers, and dehumidifiers. Getting drying equipment in place fast is the single most important factor in preventing mold and secondary structural damage. Learn more about our water damage restoration service.

4
Document Everything for Your Insurance Claim

Before cleanup begins, photograph and video every affected area thoroughly. Make a written inventory of damaged items. Do not throw anything away before your insurance company has assessed the damage โ€” adjusters may need to inspect damaged materials in person.

5
Notify Your Insurance Company

Contact your homeowners insurance company as soon as possible. Most policies require prompt notification. Working with a restoration company experienced in insurance claims โ€” like Greene Group โ€” can streamline this process. We work directly with all major insurers and document damage in a way that supports a complete, fair settlement.

6
Begin Safe Water Removal

If safe to do so, remove standing water with mops, towels, or a wet/dry vacuum while waiting for professionals. Remove wet rugs, furniture, and soft goods from the affected area. Elevate furniture on wood blocks or aluminum foil.

7
Watch for Mold in the Weeks That Follow

Stay alert for signs of mold after water damage โ€” musty odors, dark spots on walls or ceilings, or respiratory symptoms. If you notice any of these, call for a mold assessment promptly. See our mold remediation service for details on what to expect.

Pro tip: Greene Group handles the complete restoration process โ€” water extraction, structural drying, mold assessment, demolition, and reconstruction โ€” under one roof. This single-contractor approach eliminates scheduling gaps and communication breakdowns common when homeowners coordinate multiple vendors.
