What to Do in the First Three Days After Floodwater Gets Inside

A flash flood cleanup checklist for the first 72 hours comes down to five steps in order: get back in safely, document everything before you move it, call your insurer, tear out what can't be saved, and get the house dry within 24 to 48 hours. Mold sets in after that window, and gaps in your paperwork are what shrink claims.

• Hours 0 to 6: Wait for officials to clear the area. Stay away from wet electrical equipment and open flames, and run generators outdoors only.

• Hours 0 to 12: Photograph and video all the damage, mark the flood lines, save material samples and call your insurer.

• Hours 12 to 48: Pull out soaked carpet, pad, drywall, insulation and porous items, then disinfect.

• Hours 24 to 48: Dry everything with fans, AC and dehumidifiers.

• By hour 72: If the water was muddy or contaminated, or you can't dry it in time, hire a licensed restoration crew.

What happened in Hurricane, and why the first three days matter

On Thursday, Oct. 22, 2026, flash flooding along Gould Wash in Hurricane, Utah, damaged about 80 homes and 50 RVs at Willow Wind RV Park. The city puts the total at roughly 130 residential structures and says the count is preliminary. Mayor Clark Fawcett declared a local emergency, and the city's press release says bridges, culverts, public roads and electrical power boxes were damaged too. Residents in the affected flood plain were notified at about 8:30 a.m. According to the city, it is still assessing the full extent of the damage, the costs and whether residents will be displaced.

Utah Public Radio reported that police ordered an early-morning evacuation of Willow Wind and of homes along Gould Wash. UPR also reported that the American Red Cross opened an emergency shelter at 270 S 700 W in Hurricane. Shelter details change quickly, so check before you go. The Salt Lake Tribune quoted Glen Merrill, a hydrologist at the National Weather Service's Salt Lake City office, who said 1 to 2 inches of rain fell in an hour along Gould's Wash.

This has happened before. In August, KUTV covered crews cleaning up Pecan Townhomes after water came down Gould Wash from outside city limits. City Manager Caden DeMille told the station, "We've seen large trees and stumps that apparently have come from the east side of the city, up above." A flood-control fix has been in the works. Fox13 reported a proposed Gould Wash project of about $63 million, with $58 million coming from the federal government. KUTV reported that the city and NRCS would seek $67 million for a dry detention basin on the east bench. Neither one helps a house that is wet today. What you do over the next three days decides how much of your home and your claim you save.

Hours 0 to 6: Get back in safely

Go back only after authorities say it's safe. Hurricane City asks residents to follow posted road closures and detours, and not to enter flooded roadways or areas with water, mud, debris or damaged infrastructure. Fox13 also noted that mud on roads could disrupt essential services.

Once you're cleared to go inside:

• Electricity: FEMA says, "Do not touch electrical equipment if it is wet or if you are standing in water." Shut off the power only if you can do it safely. The CDC also says to unplug appliances so you don't get shocked when the power comes back on.

• No open flames: Don't use matches or lighters, because FEMA warns "gas may be trapped inside."

• Generators: The CDC says, "Never use a generator inside your home or garage, even if doors and windows are open." Run it outside, more than 20 feet from any window, door or vent.

• Gear up: Wear rubber boots and plastic gloves for the cleanup (CDC).

• Food and water: Throw out any food or bottled water that may have touched floodwater. FEMA's rule is "When in doubt, throw it out!"

Hours 0 to 12: Document before you move anything

The quality of your documentation drives your claim, so take photos before you start tearing anything out. The FloodSmart NFIP claims checklist and FEMA recommend that you:

• Shoot photos and video of all the damage "from multiple angles and distances."

• Record the "floodwater lines inside and outside of your structure."

• Write down the make, model and serial number of each damaged appliance.

• Save samples or swatches of carpet, flooring, blinds, wallpaper, upholstery and window treatments.

• "Separate damaged property from undamaged property."

Call your insurer right away. FloodSmart's advice is "Don't delay reporting your claim." Keep a simple log of every call: the date, who you talked to and what they told you. A notebook on the kitchen counter is plenty.

The Utah insurance reality check

For most Utah families, this is the part that decides everything. The Utah Division of Emergency Management puts it bluntly: "Most homeowners' and renters' insurance does not cover flooding events." The state also says federal disaster assistance "is only made available when a Presidential Disaster is declared," that "in the state of Utah most flood events do not result in a declaration," and that the aid "comes in the form of a loan that must be repaid."

If you have a National Flood Insurance Program policy, you're in better shape:

• FEMA says "National Flood Insurance Program claims do not require a disaster declaration."

• Per FEMA, submit your signed Proof of Loss "within 60 days after the date of loss," along with a building damage estimate and a personal-property inventory. FloodSmart says you can also use whatever timeframe your adjuster or insurer gives you.

• You can ask for "an advanced partial payment" to get started on repairs.

• When the adjuster shows up, ask to see their Flood Control Number (FCN) card and a government-issued photo ID.

Hours 12 to 48: What comes out first

Once the photos are done, start hauling. FEMA says to remove and throw out:

• Drywall and insulation "that was contaminated with floodwater or sewage"

• Carpeting and carpet padding

• Mattresses, pillows and stuffed toys

• Anything else that can't be washed and cleaned with a bleach solution

An archived 2008 CDC advisory made the same point: "Remove all porous items that have been wet for more than 48 hours and that cannot be thoroughly cleaned and dried." Before you toss anything, keep the samples your adjuster will want.

After the mud-out, disinfect hard surfaces with the CDC's mix: "1 cup of bleach and 1 gallon of water." That same 2008 advisory has a warning worth taping to the wall: "Never mix bleach with ammonia or other household cleaners."

The 24 to 48 hour mold clock

The EPA says "it is important to dry water-damaged areas and items within 24-48 hours to prevent mold growth." The CDC recommends fans, air conditioning units and dehumidifiers.

Don't count on the desert to do the work. Dry Southern Utah air helps on exposed surfaces, but it doesn't get into a wall cavity or under a layer of mud. A floor that looks dry on Saturday can still be wet underneath.

When to call a restoration crew

The EPA guidance gives you clear lines. Call a professional when:

• The water was contaminated. For sewage or other contaminated water, the EPA says to "call in a professional who has experience cleaning and fixing buildings damaged by contaminated water." Muddy flash floodwater coming down a wash belongs in this group.

• Mold covers more than about 10 sq ft. The EPA says homeowners can usually handle smaller areas themselves.

• Water got into wall cavities or under flooring where you can't reach it.

• You can't get it dry within 48 hours with the equipment you have.

A pro crew brings truck-mounted extraction, cuts out the wet lower section of drywall (a "flood cut") and uses moisture meters. Ask for written drying goals and daily meter readings, and keep copies for your adjuster. Rytech, a restoration company, puts the industry average for drying out a typical home at 4.9 days. It adds that replacing saturated drywall can tack on several days to two weeks. Rytech also says a house is done when it meets IICRC criteria, such as indoor humidity trending down and repeated moisture-meter readings, not when a certain number of days has passed. A crew that pulls its equipment on day three without showing you dry readings is a red flag.

What flood cleanup costs: Southern Utah vs. Phoenix vs. Denver

HomeYou's modeled 2026 estimates for a 215 sq ft flood cleanup (about 33.4 labor hours plus materials) come out close in all four markets:

HomeYou's Hurricane page puts labor at about $60 to $80 an hour and says Category 3 water costs more. For water mitigation (the extraction and drying stage), its 2026 models for the same 215 sq ft are $2,977 to $3,458 in St. George, $2,998 to $3,485 in Phoenix and $3,063 to $3,562 in Denver.

What this means for you: your zip code moves the price less than the kind of water, how much area got wet and what materials were soaked. National figures from Fixr (updated January 2025) show how fast the water category changes the bill:

• Extraction, clean water: $3.75 to $4.25 per sq ft

• Extraction, gray water: $4.10 to $6.50 per sq ft

• Extraction, black water: $7 to $7.50 per sq ft

• Drywall restoration: $1.50 to $3 per sq ft

• Carpeting: $4.75 to $10.50 per sq ft

• Mold remediation: $1,500 to $4,000

• Drying out a 500 sq ft basement: $2,000 to $7,000, not counting repairs

Fixr's typical range for water damage restoration nationally is $1,200 to $5,000, with an average around $3,000. Here's how to scale it: black-water extraction alone on 500 sq ft works out to about $3,500 to $3,750 at Fixr's rates, before any drywall, flooring or contents. If a quote for muddy floodwater comes in near the clean-water rate, ask what the crew left out.

Vetting the crew before you sign

After a flood, door-knockers show up fast. Before anyone starts work, take five minutes to check their license. The City of Springville's guide walks through the Utah DOPL lookup:

• Go to dopl.utah.gov and click "Verify a License."

• Search by name, business or license number. Utah contractor licenses end in -5501.

• Confirm the license is active.

• Check the "Classifications" section to make sure the holder is licensed for the work you need.

Get an itemized written estimate that lists extraction, demolition, drying equipment days, disinfection and rebuild separately. Get two bids and compare them line by line. Keep copies of everything for your adjuster.

The decision: DIY or call a pro?

You can likely handle it yourself if:

• The water was clean, not muddy or sewage-tainted

• It stayed on hard floors and didn't wick into walls

• Any mold is smaller than about 10 sq ft

• You can get everything dry within 24 to 48 hours with fans and dehumidifiers

Call a licensed restoration pro if:

• Muddy floodwater from the wash came inside (treat it as contaminated)

• Drywall, insulation or carpet pad got soaked

• You can't verify dryness without moisture meters

• You need professional documentation to support an NFIP claim

A fair price for a single-room cleanup in Southern Utah runs about $3,000 to $3,700 by HomeYou's models. Contaminated water and bigger areas push it higher. For local road closures, damage reporting and recovery updates, contact Hurricane City at 147 N 870 W, Hurricane, UT 84737, or call 435-635-2811.
