What To Do in the First 24 Hours After Water Damage

If a pipe has burst, a supply line has failed, or you’ve come home to standing water, the first 24 hours determine how much of your home you save and how much you lose. Shut off the water source, cut power to the affected area if it’s safe to do so, remove as much standing water as you can, and start pulling wet items off floors and out of cabinets. Document everything with photos before you move anything. Water that sits for more than a day soaks into subfloor, drywall, and baseboards, and that’s when a cleanup job turns into a demolition job.

Assess the Situation Before You Touch Anything

Not all water damage looks the same, and what you’re dealing with changes your first move.

• Clean water from a supply line, water heater, or rain intrusion is the easiest to manage if you act fast.
• Gray water from a washing machine overflow or dishwasher leak carries some contamination and shouldn’t be handled with bare hands for long.
• Black water, from sewage backup or flooding that’s picked up groundwater and waste, is a different category of problem entirely and isn’t a DIY cleanup situation.

If you’re not sure which one you’re looking at, treat it as contaminated until you know otherwise. Denver’s older neighborhoods, especially homes built before the 1970s around areas like Berkeley and Washington Park, often still have original cast iron or galvanized plumbing that’s more prone to failure than newer PEX systems, so a pipe burst in an older home can release more water, faster, than you’d expect.

The First Steps, In Order

1. Stop the source. Shut off the main water valve if you can’t isolate the leak to a single fixture. Most Denver homes have the shutoff near the water meter or where the line enters the basement or crawl space.
2. Cut the power to any outlets or fixtures in the wet area at the breaker panel, not at the switch, if water is anywhere near electrical.
3. Photograph everything before you move or remove anything. Wide shots of the room, close-ups of damaged materials, and anything that got wet. Insurance adjusters work off documentation, not memory.
4. Remove standing water. A wet/dry shop vac handles small amounts. For anything beyond a few inches, you’ll need pumps and extraction equipment most homeowners don’t own.
5. Pull up what you can. Rugs, furniture legs, boxes, anything sitting directly in water should come off the floor. Prop up furniture with foil or wood blocks to keep wet legs from staining or warping further.
6. Open the space up. Run fans, open windows if Denver’s humidity is low that day, and point air movement at wet flooring and walls. Dehumidifiers help, but air movement is what actually pulls moisture out of materials.
7. Call your insurance company to start the claim, and ask what documentation they need before you discard anything.

What Not To Do

• Don’t run a shop vac or regular vacuum over water near an outlet or switch that’s still live.
• Don’t assume carpet padding is salvageable just because the carpet on top looks okay. Padding holds water like a sponge and almost always has to come out.
• Don’t wait to see if it “dries on its own.” Drywall and wood framing can read dry on the surface while the material behind it is still saturated, and mold can begin colonizing within 24 to 48 hours in the right conditions.
• Don’t throw away damaged items before photographing them. Adjusters often want to see the actual damage, not just a description of it.
• Don’t use household fans alone as your only drying strategy for anything beyond a small, contained spill. Without proper air movement and humidity control, materials trap moisture for days.

When It’s Time to Call a Professional

A sopped-up spill from a dishwasher or a small supply line leak is often manageable on your own, especially if you catch it within an hour or two. But several situations call for a professional water damage crew:

• Water has spread under flooring, behind baseboards, or into a wall cavity where you can’t see or reach it.
• The source was anything other than clean water.
• Water sat for more than a few hours before you found it.
• You hear or feel sponginess in flooring, which usually means water has already gotten into the subfloor.
• The affected area is large enough that household fans and a shop vac clearly aren’t going to cut it.
• You’re dealing with a finished basement, where water tends to travel further and hide more effectively than in an open room.

Legacy Resto llc handles water damage restoration and emergency water removal for homes and businesses in Denver, using moisture meters and thermal imaging to find water that’s traveled beyond what’s visible, then drying the structure per IICRC S500 standards rather than just running fans until things look dry. That distinction matters: a wall that looks fine two weeks later but was never actually dried to standard is where mold problems start.

What Happens After the Water Is Gone

Extraction is just the first phase. After standing water is removed, the real work is structural drying, which usually takes several days of monitored dehumidification and air movement, not a single afternoon. A technician will use moisture meters to track drying progress in framing, subfloor, and drywall, because visual dryness and actual moisture content are two different things.

Once everything reads dry, you’re looking at repairs: replacing drywall, baseboards, flooring, or insulation that couldn’t be saved. If the damage affected a larger area or structural materials, that’s where reconstruction work comes in, rebuilding what had to be removed so the space is back to its original condition. Throughout the process, keep copies of every photo, receipt, and communication with your insurer. Water damage claims move faster and get resolved more fairly when the paper trail is solid from day one.

If you’re standing in a wet room right now trying to decide what to do next, start with the shutoff valve and the steps above. If the water came from anything other than a clean source, or you’re not confident you can dry the space completely on your own, Legacy Resto llc can be reached at (888) 249-5867 to assess the damage and start the drying process before it turns into a bigger repair.
