How to Prevent Drywall Rot

Moisture problems in your home can cause extensive damage to a variety of surfaces. It’s important to keep a vigilant eye on every area of your home to make sure that issues don’t escape your notice. Left unrepaired, problems such as drywall rot can have devastating repercussions for your home.


Whether you have winter condensation problems, mildew or even a musty basement, deal with it quickly to minimize damage. Once you know how to prevent drywall rot, you’ll be in the perfect position to keep your home in superior condition.

  1. 1.Health Hazards

    Conduct frequent inspections with a water meter to measure the moisture in your walls. The water meter will measure moisture by radio waves.

    Thanks to the building boom that pushed production through the roof several years ago, some substandard materials made their way into the United States from China. The ramifications resulting from these materials can be exceedingly hazardous to consumers – especially if moisture and rot come into the picture.


    Although the appearances of high quality and substandard drywall can be identical, you should be able to determine if you have a problem by the odors that will ensue with moisture issues. If you begin to detect sulfur or rotten egg odors in your interior rooms, this indicates that you may have hazardous drywall in your home that is causing potentially unhealthy conditions.


    Unfortunately, the only remedy for this situation is to remove every bit of drywall from your home and then repair any corrosion that also occurred. If you allow these materials to remain in your home, you may expose your family to dangerous hazards.


    Even if you don’t have substandard drywall in your home, moisture on drywall can lead to mold problems in the home, which is also unhealthy.

  2. 2.Prevention

    Install drywall made with a fiberglass outer layer instead of paper. The fiberglass is a more effective moisture barrier than paper, keeping water from seeping through the layers.


    Prevent moisture from seeping in through cracks at doors and windows by making sure you install these features correctly. Maintain your roof properly to prevent moisture from leaking through the roof. Proper roof maintenance includes checking flashing, sealing cracks and ensuring that shingles are in good condition. It’s also important to make sure those areas around plumbing fixtures, pipes are safe from damage and that all fixtures drain correctly without leaks.

  4. 3.Inspections

    Because water damage can happen insidiously without your knowledge at first, it’s important to conduct frequent inspections of your home to ensure that issues aren’t occurring undetected. Watch all areas of your home for clues or indications of water damage. If you see discoloration on floors or walls or if you notice soft drywall, you may have moisture problems. You may also notice mold or mildew occurring on the wall.


    Conduct frequent inspections with a water meter to measure the moisture in your walls. The water meter will measure moisture by radio waves.


    With an eye for detail and ongoing vigilance, you can keep your home safe from moisture damage. Once you understand how to prevent drywall rot, you’ll be in the ideal position to maintain your walls properly.
