Water damage can spread faster than most homeowners realize. What starts as a burst pipe or basement flood can become a full-scale structural disaster — and a mold problem — within 24 to 48 hours if not handled correctly. If you’ve just discovered water damage in your Long Island home, the next few hours are critical.
This guide covers exactly what to do — and what not to do — from the moment you discover water damage until the restoration team arrives.
Step 1 — Ensure Safety First
Before doing anything else, confirm it’s safe to enter the affected area.
Check for electrical hazards
Water and electricity are a deadly combination. If standing water is present near any electrical outlets, panels, or appliances, do NOT enter until the power to that area has been shut off at the breaker. If you’re unsure, stay out and call a professional.
Check for structural damage
Look for sagging ceilings, warped floors, or walls that appear bowed. These are signs of structural compromise. Don’t walk under a sagging ceiling — it can collapse without warning.
Check for gas leaks
If you smell gas, leave immediately and call your gas company before re-entering.
Step 2 — Stop the Water Source If Possible
Find the source of the water and stop it if you safely can.
- For burst pipes: Locate your main water shutoff valve (usually in the basement, utility room, or outside near the foundation) and turn it off completely.
- For appliance leaks: Turn off the water supply valve behind the dishwasher, washing machine, or refrigerator.
- For roof leaks or storm damage: You can’t stop the rain, but you can move valuables away from the affected area.
Important: If you can’t find the shutoff or aren’t sure, call Island Shield at 516-521-9387 — we can walk you through it over the phone.
Step 3 — Call Your Restoration Company Immediately
Call Island Shield Restoration at 516-521-9387 before you do anything else. Here’s why timing is so critical:
- Within 1 hour: Water begins soaking into drywall, insulation, and subfloor
- Within 24 hours: Mold can begin growing in saturated materials
- Within 48 hours: Structural materials can warp, swell, and become unsalvageable
- Within 72 hours: Full mold colonization can occur; salvage window for hardwood floors closes
The faster we arrive, the more we can save — and the less your claim will cost.
Step 4 — Call Your Insurance Company
While waiting for the restoration team, call your insurance company to report the claim. Have this information ready:
- Policy number
- Date and time the damage occurred
- Brief description of what happened
- Your contact information
Important: Don’t wait until after the cleanup to call your insurer. Delayed reporting can complicate your claim. Island Shield will handle all documentation and work directly with your adjuster — but the initial report should be made promptly.
Step 5 — Document Everything
Before moving anything, take photos and video of:
- All standing water and affected rooms
- Damaged furniture, appliances, and belongings
- The source of the water if visible
- Any visible mold or discoloration
Don’t throw anything away yet — even items that appear destroyed may be covered under your policy’s contents coverage.
What NOT to Do After Water Damage
Don’t use household fans or a regular vacuum
Household fans move air but don’t dehumidify. They spread moisture to unaffected areas and can aerosolize mold spores if mold is present. Regular shop vacs can handle small amounts of water but are useless for structural drying.
Don’t walk on wet hardwood floors more than necessary
Every step on saturated hardwood accelerates warping and cupping. Minimize foot traffic until the drying equipment is running.
Don’t turn on the HVAC system
Your heating and cooling system can distribute water vapor and potential mold spores throughout your entire home.
Don’t wait to see if it dries on its own
Water wicks through drywall and insulation invisibly. A wall that feels dry to the touch can have moisture readings of 40%+ inside. Professional thermal imaging and moisture meters are the only way to confirm thorough drying.
Don’t discard any damaged items
Personal belongings, furniture, and appliances may all be covered under your insurance policy’s contents coverage. Document everything before moving it.

Long Island-Specific Water Damage Risks
Long Island homeowners face unique water damage risks due to our coastal location and climate:
- Frozen and burst pipes: January and February bring the most pipe burst calls. Homes built before 1980 are particularly vulnerable due to older copper plumbing and uninsulated exterior walls.
- Nor’easter flooding: Basements across Suffolk and Nassau County flood regularly during major coastal storms. If your basement has flooded before, it will flood again — proper waterproofing and a sump pump backup are worth the investment.
- Storm surge and tidal flooding: Homes within a mile of the coast face storm surge risk during major storms. This water is contaminated and requires specialized remediation — not just drying.
- Aging infrastructure: Many Long Island homes have aging supply lines, original cast iron drain lines, and original roof materials that are approaching end of life. Annual inspection is the best prevention.
