It doesn’t take much to make the walls wet. A leaky pipe upstairs drenches drywall in the rooms below. Rain water seeps under window sills soaking sheetrock. Once you figure out the problem and get it fixed, you still have a soggy situation on your hands.

It almost sounds like a riddle. How do you go about drying drywall water damage mold?

As Chicago’s leading water cleanup and restoration company, we know that drying wet interior walls can be a successful DIY job. By following our guidelines, you can assess the damage, dry out that soggy drywall and restore your room’s original good looks.

Wet Walls Wick Up Problems

Whether it’s a washing machine disaster in the laundry room or a slow, hidden leak under the kitchen sink, you can count on adjacent drywall turning into a sponge. Its porous material quickly absorbs moisture and wicks it up into the wall. The damp spreads behind trim, bleeds under baseboards and saturates insulation.

Drywall isn’t load-bearing, but its condition affects surrounding infrastructure. When it becomes wet, the material turns into a breeding ground for unhealthy mold growth. Fast-growing microbial colonies multiply quickly by releasing airborne spores.

You have to dry out wet walls as soon as possible to head off potential health problems that can spread throughout your home’s wood framing, crawl spaces and ductwork.

How to Dry Out Wet Drywall in 5 Steps

1. Gauge the Extent of the Damage

It’s easy to spot wet areas on wall surfaces, but how to tell if drywall is wet below the surface isn’t always obvious. Trust your visual inspection to determine the general location of water damage, but gauge the extent of the problem with a moisture meter. Any reading above 1 percent or out of the meter’s green zone indicates compromised drywall material.

You can buy a decent moisture meter at your local hardware store or for instance online at Amazon.com for less than $40

Power Tip: Make your inspection easier and speed up drying time by moving everything out of the room. Be sure to check carpet and padding for water damage, and pull it up if necessary.

2. Factor in Wall Covering or Paint Type

If you can easily see the damp in your sheetrock, the walls are probably painted with one or two coats of flat or semi-gloss paint. These finishes don’t seal up moisture in the drywall, and that makes the drying job easier.

Areas covered with vinyl wallpaper, high-gloss enamel or more than one layer of wallboard take much longer to dry and may need professional attention.

Power Tip: Remove baseboards and trim to help speed up the wall drying process, and be on the lookout for any signs of potential mold growth.

3. Be Prepared to Rent Equipment

You can rent professional dehumidifiers at your local hardware store.
You probably don’t own heavy air-moving equipment necessary for this kind of job, but you can rent high-volume fans and large dehumidifiers at home improvement centers.

Explain your project to store personnel, and ask about equipment specs. You want a dehumidifier that generates temperatures around 115 degrees Fahrenheit at no more than a 14 percent relative humidity.

4. Seal, Fire Up, and Monitor

Make the room as airtight as possible by taping plastic sheeting over doorways and windows. Fire up the equipment, keep a close eye on the dehumidifier’s collection well, and regularly check progress with your moisture meter. On average, it takes three days to completely dry wet drywall.

5. Double Check and Repaint

Put the moisture meter to work one last time to be certain that your sheet rock walls are completely dry. When you’re confident that the job’s finished, paint over affected drywall with a thin coat of alcohol- or oil-based primer.

Feather into surrounding areas that don’t need repainting, and let dry. Repeat the prep process, and then finish off your now-saved drywall with a fresh coat of paint.
