Bathroom Black Mold Removal and Prevention

The black mold sources in older homes Older buildings can often have “cold spots” on walls and ceilings owing to inadequate ventilation in cooler climates. You might have too little insulation on a ceiling in your attic, or more broadly, you won’t be able to install enough insulation because there’s insufficient space at the edge of the roof at the close spot. You will have 4 “walls on a wall where you should have 6” walls potentially.Do you want to learn more? Visit The CleanUP Guys.

The hazard zone on the walls is where there is a window header that occupies the whole 3.5 “of a 4” wall-in that position you only have the 3.5 “of wood as insulation, which means that you you have the R-value of theR-4 in that section! In these cold places, the moisture in the bathroom will actually condense, even whether the wall or roof is cool, the moisture will not immediately break up adding to the mold. That’s kind of a big challenge, since you have to move the toilet or tub. We got our toilet and pool fixed as it destroyed our old one. Using fiberglass and 2 “thick foam (over headers) we lined the outside wall. We placed 2” foam over ceiling joists, taking down our ceiling by two inches and creating a cold-proof shield. It means no cold spots around ceiling joists are feasible. To fasten the drywall to the ceiling through the silicone, we used 4 “drywall screws per 6-8”

To have a bit more protection we used mold-resistant drywall, mortar and paint.

Make sure you have a fan in your bathroom. And insulating around the ventilation pipe exiting the fan-otherwise the interior of the pipe can condense with moisture.
