How to Dry Wet Carpet (and When It Can't Be Saved)

Wet carpet looks like a surface problem, but most of the water sits below it in the pad and on the subfloor. That's why a carpet can feel dry on top and still smell musty a week later. If a whole room or basement is soaked, ReestorianPros can connect you with a local provider for water extraction and drying in Littleton who can measure moisture under the carpet, not just on top.

This is general information. Turn off power to the room before working near standing water, and treat any water from a toilet, sewer or flood as contaminated.

How do you dry wet carpet?

• Stop the water. Fix or shut off the source, such as a supply line, appliance or leak.
• Check what kind of water it is. Clean water can be dried. Sewage or floodwater means the carpet and pad should be thrown out.
• Move furniture off the carpet. Put foil or plastic under any legs you can't move, so stains don't transfer.
• Remove the water. Go over the area slowly with a wet/dry vacuum or extraction vacuum, in overlapping passes.
• Lift the carpet. Pull it back from the tack strip at a corner so air reaches the pad and subfloor.
• Deal with the pad. Thin, lightly damp pad may dry; soaked pad usually comes out.
• Run fans and a dehumidifier. Point fans across the floor and under the lifted carpet, and keep doors and windows closed so the dehumidifier can work.
• Check moisture daily by feel and smell, or with a moisture meter, until the subfloor is dry.
• Clean and reinstall once everything is dry.

The EPA's water damage table for carpet and backing lists the same core steps. It calls for removing water with an extraction vacuum, lowering indoor humidity with a dehumidifier and speeding drying with fans.

How to dry wet carpet fast

Opening windows helps only when the outside air is drier than the air inside. On a humid day, it can slow things down.

Can you vacuum wet carpet?

Not with a regular household vacuum. Upright and canister vacuums aren't made for water, and using one on a soaked carpet risks the motor and a shock. Use a wet/dry shop vacuum, and empty its tank often. For large areas, rental extraction machines or a professional truck-mounted unit remove far more water than a shop vacuum. Keep extension cords and outlets off the wet floor.

How long does it take to dry wet carpet?

These are rough ranges, not promises. The EPA says mold usually won't grow if wet materials are dried within 24 to 48 hours. Read how long it takes mold to grow for more.

How to get rid of wet carpet smell

A musty smell means moisture is still there, usually in the pad or on the subfloor. Covering the smell doesn't fix it.

1. Dry it completely. Keep fans and the dehumidifier running until the pad and subfloor are dry, not just the surface.
2. Clean the carpet with a carpet cleaning solution or hot water extraction once it's dry.
3. Sprinkle baking soda on dry carpet, leave it for several hours, then vacuum.
4. Replace the pad if the smell returns after everything is dry.
5. Keep humidity in check. The CDC recommends keeping indoor humidity no higher than 50%.

If you see mold growth on the carpet backing or the tack strip, the CDC says it should be cleaned up and the moisture problem fixed.

How to clean wet carpet

The right cleanup depends on what the water carried. The ANSI/IICRC S500 standard groups water into three categories by contamination.

Colorado public health guidance for sewer backups says wall-to-wall carpet that sewage reached should be thrown out, and the pad replaced. Floodwater carries the same kinds of contamination, so treat flood-soaked carpet the same way. Wear gloves, boots and eye protection when removing contaminated carpet.

When wet carpet can't be saved

• Sewage, floodwater or a toilet overflow with waste soaked it
• It stayed wet for more than 48 hours
• It smells musty even after drying
• You see mold on the backing, pad or tack strip
• The backing has separated from the surface (delamination)
• It was glued directly to a concrete slab and is soaked through

Rugs can sometimes be saved even when wall-to-wall carpet can't, because they can be taken out and cleaned and dried separately. Ask a rug cleaner.

Drying carpet in Colorado basements

The Front Range's dry air helps carpets dry, but basements are a different story. Carpet over a concrete slab dries more slowly because the slab holds moisture and stays cool. Many Littleton homes have carpeted lower levels, so a basement water heater leak or a window well backup can soak a lot of carpet before anyone notices. Run the dehumidifier until readings drop, and check the slab under the pad, not just the carpet surface. The basement flood checklist covers the first steps.

How to prevent wet carpet problems

• Keep a wet/dry vacuum in the basement so you can start right away.
• Add leak sensors near the water heater, washer and sump pump.
• Keep basement humidity below 60%, as the EPA recommends, and ideally 30% to 50%.
• Use area rugs instead of wall-to-wall carpet in basement rooms that have flooded before.
• Clear window wells and keep downspouts pointed away from the house.

When should you call a water damage professional?

Call a professional when:

• More than one room of carpet is soaked
• The water came from sewage, a toilet with waste or outside floodwater
• The carpet is still wet after a day of fans and a dehumidifier
• It smells musty after drying, or you see mold
• You need moisture readings and photos for an insurance claim
