When it comes to fixing your wet drywall, it’s in your best interest to take the process in steps. First, identify your leak. Rapid changes in temperature can cause the pipes to burst, and hydrostatic pressure can build up outside of your home and force cracks to form in your home. Once you’ve identified your leak, you’ll want to reach out to the professionals serving your area to fix it. Should you leave a leak in place, your new drywall will likely find itself wet and unsafe within a week or two of your initial installation. After that, replace your drywall. To replace damaged drywall in your home, you can:
Measure the hole left in your wall   Fill the hole with appropriately sized drywall clips   Secure the clips with drywall screws   Blend drywall tape and joint compound to smooth out the wall   Sand the wall until you’re satisfied
After you’ve replaced your drywall and ensured that all other damage to your basement or foundation has been attended to, you can discuss home waterproofing measures with a professional contractor in your area. They will prove most effective for you and will vary based on the circumstances that led to your initial leak. For example, if a pipe burst inside of your home due to dropping temperatures, you may want to invest in a dehumidifier. Alternatively, if it was external flooding that caused humidity levels in your home to rise, you might consider hydrophobic insulation, a vapor barrier, or a sump pump.
