Do you need to replace drywall if it gets wet?

One of the most common questions homeowners ask is “Do I need to replace my drywall if it gets Wet?” The answer, unfortunately, is usually yes. Wet drywall is a common problem in homes and can cause major damage. In this blog post, we will outline the causes of wet drywall and discuss the steps you should take to prevent or fix the issue.

How Wetness Affects Drywall

Wetness affects drywall in a few ways. First, wet drywall sticks together more easily than drywall, so nails that are put in place to hold it together may not hold as securely. Additionally, water can damage the paper and insulation inside the drywall, which can lead to Mold or Water Damage. Finally, if water gets on the wall and drips down, it can cause mold and other moisture-related problems.

How to Test for Wetness in Drywall

If you have newly installed drywall, or if it has recently been wetted, you may want to test for wetness before making any decisions about whether or not to replace the drywall. There are a few ways to test for wetness in drywall:

-Moisture meter: This is the most accurate way to determine if drywall is wet. Simply measure the moisture content of the wall and compare it to the manufacturer’s recommended value.

-Tape measure: To test for surface moisture only, use a tape measure to check how much water seeps through the drywall when pressure is applied. The amount of water that seeps through indicates how wet the surface is.

-Touch: To test for subsurface moisture, touch the wall gently with your fingertip. If there’s moisture present, it will feel moist.

-Drywall tester: A drywall tester is a handheld tool that uses sound waves to measure wetness. It emits a high-pitched noise when wet and a low-pitched noise when dry. You can use a drywall tester to test small areas or specific areas of the wall.

If you’re unsure whether or not to replace the drywall, it’s best to test for wetness and make a decision based on the results.

Testing for Water Damage

There are a few things you can do to test for water damage before making any decisions about repairing it.

1. Take pictures of the affected area. Pictures will help you document the condition of the drywall and any apparent damages.

2. Inspect the drywall for any water damage or blisters. Blisters are bubbles that form on the surface of drywall when it is wet and expands as the moisture vaporizes. Water damage will show up as a wet or damp spot on the wall, and may also cause sagging or buckling in framing members.

3. Check for electrical wires and plumbing that may have been exposed to water. If they have been wet, they may have been damaged and should be replaced if necessary.

4. Test for mold growth by touching the surface where water was applied with a clean cloth (do not put your fingers inside!). Mold growth indicates that spores have entered the air and are likely growing in moist conditions.

5. Check the insulation in the walls and attic for moisture damage. Moisture can cause serious problems with insulation, including weakening of the fiber, loss of heat, and possible fire.

Replacing Damaged Drywall

If your drywall gets wet, it’s important to replace it. Wet drywall can cause a lot of damage, including leaks and mold. Here’s how to replace drywall if it gets wet:

1. Remove the damaged drywall. If there are any nails or screws in the drywall, remove them first.

2. Fasten the new drywall in place using screws or nails. Make sure that the seams are smooth and flush with the surrounding walls.

3. Apply a sealant to the joint between the new and old drywall and then paint or wallpaper over it.

4. Replace any lamps, pictures, or other objects that were attached to the drywall with new ones.

5. Leave the new drywall up for at least two days so that it can dry fully.


It can be difficult to determine the right course of action when it comes to repairing water damage. In general, if water gets inside the walls and reaches moisture levels, you will need to replace drywall. However, there are a few factors that can affect this decision: the type of drywall used, how wet the wall was when it was damaged, and whether or not any insulation is present. If you are in doubt about whether or not water damage requires drywall replacement, contact a professional contractor like ours who will be able to provide an accurate assessment.
