Water damage is decided in the first two days. What you do before a contractor arrives determines whether you're patching drywall or replacing subfloor and framing — and whether your insurer pays.
Hour 0–1: stop the source and make it safe
- Shut the water off. Fixture stop first, main shutoff if that doesn't hold it.
- Kill power to the area if water is near outlets, a panel, or ceiling fixtures. Don't stand in water to reach a breaker.
- Contain it. Towels, buckets, and a wet vac on standing water — but only clean water.
- Don't demo anything yet. Documentation comes before removal.
If the water is sewage or came from outside flooding, treat it as contaminated. Stay out, don't run fans across it, and get a professional on site — moving that air spreads the problem.
Hour 1–4: document like the claim depends on it
Because it does. Insurers pay on evidence, not descriptions.
- Wide photos of each affected room, then close-ups of every wet surface.
- A slow walkthrough video narrating what you found and when.
- Photos of the failure point itself — the split line, the loose fitting, the roof penetration.
- Photos of damaged contents before you move them, plus receipts if you have them.
- Write down the date and time you discovered it. Insurers ask.
Then call your carrier and open a claim. You are not committing to anything by opening one, and a late report is one of the most common reasons claims get reduced.
Hour 4–24: start real drying
Air movement plus dehumidification, not just a box fan. Pull baseboard where water tracked, lift wet carpet pad, and open cabinet toe-kicks. The goal is to get airflow into the cavities, not across the floor. Keep the room warm — cold air holds less moisture and dries slower.
Hour 24–48: find out what's actually wet
This is where homeowners and contractors part ways. A surface that feels dry can sit against soaked insulation. A moisture meter and, where warranted, thermal imaging tell you where the water traveled — usually farther than the stain suggests.
Signs the wall has to come open
- Elevated meter readings 24+ hours into drying
- Bubbling paint, soft drywall, or a stain that keeps growing
- Musty odor that doesn't clear with ventilation
- Any water that reached fiberglass insulation — it holds moisture and won't dry in place
- Water that traveled down to the subfloor or a lower level
Then: repair in the right order
Repairs done before the cavity is verified dry fail. The correct sequence is: source repaired, wet materials removed, cavity dried and documented dry, insulation replaced, drywall and texture, paint, trim, flooring. Skipping the verification step is how the same wall gets opened twice.
We've documented that exact sequence on real Vancouver projects — the flooring and dining-room leak repairs in our project gallery show the subfloor and cavity work most homeowners never see.
Frequently asked questions
What should I do first when I find water damage?
Shut off the water source, then the power to affected circuits if water is near outlets or fixtures. Photograph and video everything before you move or remove anything. Then start air movement and call a licensed contractor.
How long before water damage causes mold?
Mold can begin developing in as little as 24 to 48 hours in wet, unventilated cavities. That window is why documentation and drying need to happen the same day, not the following week.
Will my homeowners insurance cover water damage?
Most policies cover sudden and accidental water damage, such as a burst supply line, but exclude long-term seepage and lack of maintenance. Photos with timestamps and a written contractor scope substantially strengthen a claim.
Do I have to open the wall?
Often yes. Surface drying can leave insulation and framing wet behind the drywall. If a moisture meter reads elevated inside the cavity, controlled removal is the only way to dry it and verify there is no ongoing leak.
Can I just dry it myself with a fan?
For a small, clean-water spill on hard surfaces caught immediately, sometimes. For anything that reached drywall, baseboard, insulation, or subfloor, fans move surface air but do not dry a closed cavity.
