What to Do in the First Hour After Water Damage

In the first hour after water damage, do three things in this order: make the area safe, stop the water at its source, and document what happened before you move anything. Once those are handled, you can start limiting the spread and get professional drying lined up.

Minutes 0 to 10: Make it safe

Water and electricity are the biggest immediate hazard. Before you step into a wet room, look at where the water sits in relation to outlets, power strips, appliances, and the electrical panel.

• If water has reached outlets, cords, or appliances, or you would have to stand in water to reach the panel, stay out and have your utility or an electrician cut the power.
• If the panel is in a dry area and you can reach it safely, switch off the breakers for the affected rooms.
• If a ceiling is sagging or bulging, keep everyone out from under it. Saturated drywall can drop without warning.
• If the water came from a sewer, a floor drain, or outdoors, treat it as contaminated. Keep kids and pets away and avoid skin contact.
• If you smell gas, leave the house and call the gas utility from outside.

Minutes 10 to 20: Stop the water

Most indoor water damage comes from the plumbing supply: a burst pipe, a failed supply line to a toilet or washing machine, or a leaking water heater. In those cases the fix for the first hour is a shutoff valve.

Know your shutoffs

• Fixture shutoff: Toilets, sinks, and most appliances have a small valve on the supply line. Turn it clockwise until it stops.
• Main shutoff: In most Nebraska homes the main valve is in the basement where the water line comes through the foundation wall or floor, usually near the meter. Turn a wheel handle clockwise, or turn a lever handle a quarter turn so it sits perpendicular to the pipe.
• Water heater: Close the cold-water valve above the tank, then turn the unit off at the gas control or the breaker.

After the main is closed, open a faucet on the lowest level to relieve pressure and drain what is left in the lines.

If the water is coming from outside, such as groundwater rising in a basement or rain through a damaged roof, you may not be able to stop it. Concentrate on safety and on protecting belongings while help is on the way.

Minutes 20 to 35: Document before you clean

Your insurance company will want to see what the damage looked like at the start.

1. Take wide photos of each affected room, then close-ups of damaged materials and belongings.
2. Record a slow video walk-through and say out loud what you are seeing, including where the water came from.
3. Photograph the source: the failed pipe, fitting, or appliance.
4. Write down the time you found the water and roughly how far it spread.

Then report the loss to your insurance agent or carrier. Coverage depends on your policy and on the cause of the water, so ask what they need from you and write down the claim number. Our insurance claims page explains how we work alongside adjusters once a claim is open.

Minutes 35 to 60: Limit the spread

With the water stopped and the scene documented, the goal is to keep it from soaking into more material. This section applies only to water from a clean supply line. If the water is contaminated, skip it and wait for a crew with protective equipment.

• Remove standing water with mops, towels, or a wet/dry shop vacuum plugged into an outlet in a dry area. Never use a household vacuum on water.
• Lift furniture onto blocks, or slide foil or plastic under the legs. Wood stain and metal feet leave permanent marks on wet carpet.
• Move what can be moved: area rugs, boxes, electronics, books, and photos. Colored rugs left on wet carpet will bleed.
• Run the air conditioning in summer if the system itself is not affected. In a humid Nebraska July, open windows usually bring in more moisture than they let out.

What not to do

A few well-meant moves make things worse:

• Do not switch on ceiling fans or ceiling lights in a room with a wet ceiling.
• Do not pull up glued-down flooring or cut into walls on your own. Hidden moisture should be mapped first, and older building materials can contain asbestos or lead paint.
• Do not trust a surface that feels dry. Water travels under baseboards, into wall cavities, and beneath flooring, where a box fan will not reach it.
• Do not wait a few days to see how it looks. Mold can begin growing on wet materials within roughly 24 to 48 hours.

When to bring in a restoration crew

A small spill on a hard floor that you caught right away is a mop-and-fan job. Professional water damage restoration makes sense when any of these are true:

• Water soaked into carpet pad, drywall, insulation, or hardwood
• Water ran through a ceiling or between floors
• A finished basement took on water
• The source was a sewer, a drain, or outdoor flooding
• You do not know how long the water was running

At Air Force Restoration, the first visit is mostly measurement. We use moisture meters and thermal imaging to find where the water went, extract what a shop vacuum cannot, and set drying equipment sized for the space. If belongings were soaked, contents restoration can often save more than people expect, especially when items are handled early.

The short version

Safety first, then the shutoff valve, then photos, then phone calls. After that, move what you can and leave the wet building materials alone until someone has measured them. An hour of ordered work at the start shortens everything that follows.
