If you detect mold in sheetrock early, you can save the surface and just kill the mold. Unfortunately, mold on drywall isn’t usually discovered until there’s already a significant problem.
Early detection is key with drywall mold. Even if you have to tear out the section where you find the mold in sheetrock, finding it early will mean there’s less to tear out and replace.
How to Detect Mold (Even if You Can’t See It)
The best way to avoid mold damage in your house is to be vigilant and check for mold periodically. Don’t wait until you can see the mold growing on the sheetrock. By then, the damage has been done.
Check your home periodically for mold and the causes of mold:
- Check all plumbing for leaks. Fix leaks promptly. Failure to do so will lead to mold every time.
- Check all windows sills and door areas for moisture. If moisture is coming into the house, you’ll need to address that.
- Check your roof for leaks. Roof leaks aren’t generally noticed until they’ve created big problems. Inspect your roof sheeting every year.
- Pay attention to musty odors. If you have a musty odor in your home, you have mold or mildew. You’ll want to make sure it’s drywall mold, you’ll want to take care of it before it can spread.
Fix the Cause First
Mold in sheetrock doesn’t just appear. It occurs because of moisture. Figure out what’s leaking and fix that before you bother with fixing the drywall.
In the meanwhile, spray the affected drywall with Lysol to kill the mold. Place a dehumidifier close to the affected drywall to lower the moisture and minimize further damage while you take care of whatever’s causing the moisture.
Repairing Damage Caused by Mold on Drywall
If you catch mold on drywall early, you can clean it with a Borax solution. Tear out and replace the drywall instead if:
- The inside of the sheetrock has become moist or crumbly
- The drywall mould returns after an initial cleaning
- Paint is peeling over the drywall (this is often a sign of moisture from within the walls)
- Toxic black mold is involved. Don’t even mess with it. Tear it out and get rid of it.
One Foot Clearance
When tearing out sections with drywall mold is necessary, tear out the drywall to at least one foot from the mold in all directions. Mold spreads rapidly, and you can’t see the mold until it is well established. Giving yourself a one foot clearance improves your chances of eliminating all of the mold and preventing its return.
Be proactive about finding mold and the conditions that cause it. Whenever you find mold or anything that could cause mold, take care of it right away. If you have mold in sheetrock that’s deeper than the surface, you’ll need to tear out and replace the section of drywall.
