What to Do in the First Hour After Water Damage

Finding water pouring across your floor or seeping up through the basement is one of the most stressful moments a homeowner can face. In Montana, these calls often come at the worst possible times: a supply line that bursts during a minus-20-degree cold snap, a water heater that lets go while you are at work, spring snowmelt pushing into a basement in Billings, or a summer thunderstorm that overwhelms drainage around a Missoula home. The actions you take in the first 60 minutes decide how bad the damage gets.

Step 1: Stop the Water at Its Source

The single highest-value action is stopping more water from entering. Every gallon you prevent is a gallon that does not soak into drywall, subfloor, and insulation. If a supply line, toilet line, or faucet connection burst, close the nearest supply valve — usually a small oval or lever handle behind the toilet, under the sink, or beside the appliance. If you cannot find it or it will not turn, go straight to the main shutoff valve, typically where the water line enters the house: in the basement, crawlspace, utility room, or garage, or in a buried curb box outside for some rural properties.

Montana-specific note: many homes here sit on private wells rather than city water. If you are on a well, cutting power to the well pump also stops the flow — the pump switch is usually near the pressure tank. If you suspect a frozen-then-burst line, shut the main even before you find the exact break. For appliance failures, close both hot and cold supply valves and, for a leaking water heater, turn its fuel or power off per the manufacturer label.

If the water is coming from outside — snowmelt, storm runoff, or a swollen creek — you cannot shut it off, so move to the safety and protection steps below and call for flood damage cleanup help right away.

Step 2: Make the Area Safe — Electricity First

Water and electricity are a dangerous combination, and basements with furnaces, water heaters, washers, and freezers have plenty of both. If water is near outlets, cords, appliances, or the breaker panel itself, do not walk through it. If you can reach the breaker box safely from a dry path, switch off power to the affected rooms or circuits. Never touch the panel while standing in water, and never unplug wet appliances — leave that for the crew.

Move people and pets out of the wet zone, especially children and older family members who may slip on slick concrete or tile. If ceilings are sagging or bulging with trapped water, stay out from under them; waterlogged drywall can collapse suddenly.

Step 3: Protect What You Can — Fast Triage

Once the flow is stopped and the area is safe, spend ten to fifteen minutes on triage. Carry — do not drag — furniture, rugs, electronics, and boxes out of the wet area. Set furniture legs on foil or plastic lids to keep them out of shallow water. Roll up area rugs and move them to a dry room; rugs trap moisture against hardwood and can stain it within hours. Gather important papers, medications, photo albums, and small valuables first, then work outward to larger items.

For soaked clothing and bedding, move them to a bathtub or plastic bin so they stop wicking water into floors. In a basement water damage situation, remember that cardboard boxes disintegrate quickly — transfer their contents to plastic totes or bags. Resist the urge to pull up carpet or tear out drywall yourself; improper removal spreads contamination and can complicate the drying plan.

Step 4: Document Everything Before Cleanup

Before you mop a drop, photograph and video the damage. Insurers expect to see the full extent of the loss, and thorough documentation protects you if questions arise later. Capture wide shots of walls and floors, close-ups of the source, water lines on drywall, soaked belongings, and serial plates on failed appliances or water heaters.

Save damaged items until the claim is resolved rather than throwing them away — bag small items if they smell, but keep them. Start a simple log: when you found the water, when you shut it off, who you called and when, and receipts for emergency purchases. Crews providing water damage restoration also keep moisture logs and drying records that adjusters rely on, so ask the crew to share their readings for your file.

Step 5: Remove Standing Water — Only If It Is Safe

If the water is clean — from a supply line or water heater — and there is no electrical hazard, removing surface water helps. Mop, blot with towels, or use a wet-dry vacuum, working from the edges toward a drain or door. Lift curtains and upholstered skirts, and prop cushions to allow airflow. If you own box fans or a dehumidifier, set them running pointed across — not directly into — wet surfaces to encourage evaporation.

Stop immediately and wait for professionals if the water may be contaminated: any sewage backup, foul-smelling water, or water from outdoor flooding or snowmelt runoff. This kind of water carries bacteria and requires protective equipment, proper extraction, and disinfection — the core of professional sewage cleanup and flood response.

Step 6: Call for Professional Extraction and Drying

Household mopping handles the surface. It cannot pull water from pad, subfloor, wall cavities, and insulation — and that hidden moisture is what causes swelling, warping, odors, and mold. Mold can begin growing within 24-48 hours on damp drywall, wood, and fabric, which is why the first-hour call matters so much: professional emergency water extraction uses truck-mounted pumps, weighted extraction tools, commercial air movers, and dehumidifiers sized to the space, plus meters and infrared cameras to find moisture you cannot see.

When you call (888) 217-5329, describe the source (burst pipe, appliance, seepage, storm), which rooms are affected, and whether sewage or power hazards are involved. That information lets dispatch connect you with the right local crew — whether you are in downtown Billings, a suburb of Missoula, or a rural property outside Great Falls where drive time and road conditions matter. Emergency calls are answered around the clock.

Step 7: Start the Habits That Prevent the Next Loss

While you wait for the crew, note what failed so you can prevent a repeat. Was the burst line on an exterior wall with little insulation? Did the sump pump lose power during a storm? Was the water heater visibly rusted at the base? Montana winters punish weak points: uninsulated crawlspace runs, hoses left connected to exterior spigots, and thermostats set too low during vacations all lead to freeze bursts when temperatures drop toward minus 20.

Simple follow-ups pay off: know where your main shutoff is and make sure every adult in the house can operate it; disconnect garden hoses before the first hard freeze; keep heat steady during cold snaps; and consider a sump battery backup and leak sensors near the water heater, washer, and sump pit. Review the water damage restoration process so you know what the crew will do from assessment through final dry-out verification.

What NOT to Do in the First Hour

A few common mistakes make things worse. Do not walk through sewage-contaminated water or try to vacuum it with a household machine. Do not use a regular vacuum on any standing water — electrocution and motor damage are real risks. Do not turn wet electronics back on to "check" them. Do not crank the heat to maximum hoping to bake walls dry; uncontrolled heat without measured airflow and dehumidification can warp wood and feed mold in hidden cavities. And do not tear out walls or flooring before documentation and before the crew maps the moisture boundary.

Keep anyone with breathing difficulties out of damp, musty areas until the space is dried and cleaned. If discoloration or fuzzy growth appears, our mold remediation page explains how contained removal and moisture control work.
