Can wet carpet be saved after a leak or flood, or should it be thrown out?

Can wet carpet be saved?

Sometimes. Three things decide it: what kind of water soaked it, how long it stayed wet, and whether the pad and the floor underneath can be dried. Carpet wet with clean water and dried within a day or two can often be kept. Carpet soaked by sewage or by flood water from a river or stream should be thrown out, and the authorities below agree that the pad under it goes too.

What kind of water was it?

NC State Extension, whose guidance draws on the restoration industry's water damage standard, sorts water into three kinds:

• Clean water: a broken supply line, an overflowing tub or sink, or rainwater.
• Gray water: unsanitary water such as discharge from a dishwasher or washing machine, or a broken aquarium.
• Black water: water carrying disease-causing organisms, including flooding from rivers and streams.

It warns that gray water left untreated for more than 48 hours may turn into black water as microorganisms multiply. The U.S. Environmental Protection Agency draws a similar line: damage from a pipe leak or rainwater typically presents fewer hazards and affects a smaller area than a hurricane or flood. The restoration standard itself, the IICRC's S500, is sold rather than published; the Institute of Inspection, Cleaning and Restoration Certification's public summary says it assumes that finding and fixing the source of the water is the property owner's job.

What should be kept and what thrown away?

The extension's rules are the most specific of the sources:

• Carpet saturated with black water: remove and dispose of it.
• Padding saturated with gray or black water: remove and dispose of it, with no exceptions.
• Padding wet with clean water for less than 48 hours, where only part of a room's pad is wet: it can be restored. A large saturated area, it says, cannot be cleaned and dried thoroughly and should be replaced.
• Carpet saturated with gray water: a professional may clean it using a biocide and hot water extraction. Bonnet, dry foam, shampoo and absorbent-compound methods are not adequate and can spread the contamination.
• Carpet glued down without a pad: it can be cleaned in place if the water was clean.

The other authorities point the same way. The Centers for Disease Control and Prevention says that after a storm or flood you should throw away carpeting, carpet padding and rugs that you cannot clean or dry quickly. The Carpet and Rug Institute, the carpet makers' trade association, says carpet contaminated with mud, sewage or other contaminants should be disposed of along with the pad, and that soaked pad generally needs replacing because it is very hard to dry quickly. The American College of Allergy, Asthma and Immunology, answering a question about flooded homes, says all the carpeting and draperies should be thrown out.

What should you do in the first 48 hours?

Start drying at once, and start safely.

1. Make it safe. The CDC says to turn off power at the main breaker if circuits or equipment are wet, to call an electrician if you would have to stand in water to reach it, and never to use an electric tool while standing in water. It says never to run a generator or other fuel-burning equipment indoors, in a basement or garage, or near an open window.
2. Protect yourself. The EPA lists an N-95 respirator, goggles without vent holes, gloves, long sleeves and boots for flood cleanup, and says people with asthma or weakened immune systems, children and pregnant people should not take part.
3. Get the water out. The EPA's water damage table says to dry carpet and backing within 24 to 48 hours, removing water with an extraction vacuum, lowering humidity with a dehumidifier and speeding drying with fans. The extension sets a tighter target of 24 hours, after which it says professional removal and replacement is the better course.
4. Hold the fans if the water was dirty or mold is visible. The EPA's table says not to use fans until you know the water was clean. Its flood guidance says to gently clean any visible mold first, so fans do not spread it, and not to run a heating and cooling system that the flood reached.
5. Lift and dry small areas. For a small patch wet from a roof or pipe leak, the extension suggests pulling up and propping the carpet to dry, cutting away the wet pad, and waiting until the subfloor is completely dry before relaying anything.
6. Stay off it. The extension says moisture weakens the latex backing, and walking on wet carpet can make the backing separate.

How do you know the floor underneath is dry?

The EPA's table says the subfloor must also be cleaned and dried. The extension says plywood subfloors can be dried before the carpet goes back, while particleboard swells and falls apart if it stays wet for a few days and has to be replaced.

The EPA's flood guidance gives two checks. A moisture meter reading of 15 percent or less means a material is dry enough for refinishing. On a concrete slab, tape a clear plastic sheet down at the edges and wait about 16 hours; moisture on the plastic means the slab is still too wet for new flooring. It adds that drying a house usually takes several days to weeks, and that nothing that was wet should be sealed or painted until it is dry inside.

When does mold change the answer?

The EPA says porous materials such as carpet may have to be thrown away once they become moldy, because mold can fill their spaces and be impossible to remove completely. It also says that drying within 48 hours is a guideline, not a promise: mold may already have started, and it will not always appear after 48 hours.

What does it cost, and what should you sign?

HomeGuide, a cost survey, puts water extraction at a minimum of $500, or $4 to $12 a square foot, cleaning a water-damaged carpet at $300 to $2,000, and a new pad at $0.75 to $1.75 a square foot.

If you call a company to an emergency at your home, Pennsylvania law lets it ask you to waive your three-day right to cancel only on a printed emergency work authorization card, together with a written estimate. Read both before signing. How to choose a carpet cleaner covers what the EPA says to look for in a water damage professional, and what happens during a cleaning covers how a drying job differs from a routine visit. Local companies are on the carpet cleaning directory page.
