Water Damage 101
Learn what to do in the first hours after a leak, how to judge the water, and how to tell when a wet home is truly dry.
What You Will Be Able to Do
- Make a wet home safe before you touch any water
- Sort a leak into clean, gray or sewage water and know what each one changes
- Remove standing water and set up drying in the first day
- Decide whether wet drywall, carpet and floors can be dried or must go
- Spot the signs that a drying job has grown past DIY
Lesson 1
Safety Comes Before the Water
Water and electricity are the first danger in any leak. If water is near outlets, cords or the electrical panel, stay out of it. Only flip the breaker if you can reach the panel while standing on a dry floor. If you cannot, call the utility and let them cut the power.
Look up before you walk in. A ceiling that sags or drips is holding water and can fall without warning. Keep people and pets out from under it. If you smell gas, leave the home and call from outside.
Key Points
- Never wade into water near outlets, cords or appliances
- Reach the panel only from a dry spot, or call the utility
- Keep everyone out from under a sagging ceiling
Lesson 2
Stop the Source Fast
Every minute a pipe runs adds more water to dry. Learn where your main shutoff is before you need it. It is often where the water line enters the home, near the water heater, in a garage or in a basement. Turn it clockwise until it stops.
After the main is off, open a low faucet to drain the pressure out of the lines. For a toilet, sink or appliance, the small valve behind or under it stops the flow without shutting off the whole house.
Key Points
- Know where your main shutoff is before an emergency
- Open a low faucet after shutoff to drain the lines
- Fixture valves stop one leak without cutting all the water
Lesson 3
Know Your Water Category
Not all water is the same. Category 1 is clean water from a supply line or a clean overflow. Category 2 is gray water, like washer drain water or a toilet bowl with urine but no feces. Category 3 is sewage level water, including toilet waste, sewer backups and floodwater from outside.
The category decides what you can save. Clean water on carpet and drywall can often be dried. Gray water means the pad goes. Sewage means soaked carpet, pad, drywall and insulation usually go, and the job is often best left to a trained crew.
Clean water does not stay clean. After a day or two, or after it soaks through dirty materials, it is treated as gray water.
Key Points
- Category is about how dirty the water is
- Clean water turns gray with time, heat and dirt
- Sewage and outside floodwater are always Category 3
Lesson 4
Photograph Before You Clean
Once the home is safe and the water is off, take a slow video of every wet room. Then take wide, medium and close photos. Save the failed part, like a split hose or a cracked fitting, in a bag.
This takes only a few minutes and it matters. A claim is paid on what you can prove. Just do not let the photos delay drying for long.
Key Points
- Shoot a slow video of every wet room first
- Save the broken part that caused the leak
- Photos come first, but do not let them stall drying
Lesson 5
Get the Water Out
Standing water should come out within hours. A wet dry vacuum handles most small leaks. For carpet, extract hard, going over each area slowly many times. The less water you leave behind, the faster everything dries.
Carpet pad acts like a sponge. It holds water long after the carpet feels dry on top. For most people, pulling and replacing the pad is simpler than trying to dry it. Lift the carpet off the tack strip and let air move underneath.
Key Points
- Extract standing water within hours, not days
- Pad is a sponge and is often easier to replace than dry
- Lift wet carpet so air can move underneath
Lesson 6
Dry the Air and the Materials
Mold can start growing on wet materials within 24 to 48 hours. That is the clock you are racing. Fans move air across wet surfaces, and a dehumidifier pulls the moisture out of that air so it does not just soak back in.
Keep indoor humidity under 50 percent while you dry. Close windows if the air outside is humid. Warm, dry, moving air dries things fastest. Cool, damp, still air lets mold win.
Key Points
- The 24 to 48 hour clock starts when things get wet
- Fans and a dehumidifier work as a team
- Hold indoor humidity under 50 percent while drying
Lesson 7
Cut or Save the Drywall
Drywall wet with clean water that is still firm can often be dried in place within a few days. Drywall that is soft, sagging, moldy or wet from dirty water has to come out. Wet insulation behind it almost always comes out too.
Use a moisture meter to find the top of the wet line, then cut about 12 inches above it. In a home built before 1980, test the wall for asbestos and lead before you cut anything.
Key Points
- Firm drywall wet with clean water can often be dried
- Cut about 12 inches above the highest wet reading
- Test older walls for asbestos and lead before cutting
Lesson 8
Know When to Call for Help
You do not need to see water to have a problem. If walls or floors still read wet at hour 24, a drying specialist with meters and commercial equipment can find and dry what you cannot see.
Call a pro when water came from a toilet, sewer or flood, when it spread past one room, when it ran inside walls or under floors, or when a ceiling sagged. Clean water caught fast is the cheapest loss you will ever have, and slow drying is what makes it expensive.
Key Points
- Still wet at hour 24 means it is time for meters and pro gear
- Sewage, flooding and several rooms push a job to a pro
- Fast drying is what keeps the bill small
