Wet walls are often a sign of water damage. Leaking or burst pipes can dampen your walls, leading to problems such as mold growth or even structural damage. So, whenever one of your walls suffers water damage, immediately begin the treatment process.

Drying is essential for treating damp walls. Most houses have drywalls that absorb water from both inside and outside. However, water collected on the outside evaporates, and this part of the affected wall dries out quicker than the interior. As for the interior, the water collected continues to expand as it doesn’t receive enough airflow.

However, these aren’t the only factors affecting a water-damaged wall’s drying time.

Factors Affecting Water-Damaged Drywall Drying Time

You might be wondering how much time it may take for the drying process to complete. Several factors affect the time that water-damaged walls take to dry.


The more water the wall absorbs, the more time it will take to dry. So, the drying process depends on how much and how quickly the wall absorbs water.

The Drying Process

The time a water-damaged wall takes to dry depends on the drying method. For instance, relying on air drying alone may take longer than some other methods, especially those using special equipment.


Since the accessible part of the wall dries more quickly than the interior, you could try opening up the other side. So, with both sides now exposed to the external environment, the wall dries up within weeks rather than months.


Painting the wall can adversely affect the drying process. Walls coated with more paint usually take longer to dry than those with fewer layers since they trap the moisture absorbed. Wallpapers also similarly affect the drying time.

How to Dry Out Walls After a Leak?

Most water-damaged walls dry out naturally over time. However, you can quicken the process with the help of special equipment. While there are many ways to dry out water-damaged walls, the below method should help you get started.

Cut the Water Supply

Be sure to cut the water supply before you begin work. Cutting the water supply also stops the leak through the pipes behind the affected walls.

Gain Access to the Affected Areas

When dealing with water-damaged walls, ensure that the affected areas are accessible. For this, you may need to remove those baseboards, trim, moldings, and anything else that may get in the way to quicken the evaporation process. Since all the walls contain a baseboard, you can run a utility knife through them to break open the caulk seal along the edges and a pry bar to pull the baseboard out of its place.

Attend to the Damage

So, now that you have full access to the affected walls, begin the drying process by opening the windows to let in some fresh air. You could also run the fans if the weather conditions are unfavorable.

Use a dehumidifier to draw in and drive away the moisture throughout the room. Depending on the dampness, you could run the dehumidifier at higher capacities for greater effect or use heavy-duty ones. For instance, desiccant dehumidifiers reduce the moisture around the room by releasing dry and warm air.

These dehumidifiers use silica gel to suck in moisture and reduce humidity. So, they may be as effective even in places with subfreezing temperatures.

After dehumidification, make sure that the walls are dry using a moisture meter and reinstall the items you removed from the affected areas.


The time that water-damaged walls take to dry, especially those caused by the leaks from broken pipes running behind them, depends on several factors, including:

  1.     The extent of the damage.
  2.     The drying method.
  3.     Interior wall accessibility.
  4.     Paint and wallpaper.
