Removal Of Bathroom Black Mold in Drywall
Black Mold on Drywall!
Our bathroom was getting mold on our ceiling and walls within 3 weeks of cleaning off the walls with straight bleach during fall and spring months. During these months, the inside humidity could be fairly high, yet a quick dip in outdoor temps could create cold spots on walls and ceilings. And to compound this even more, the hose on our bathroom fan disconnected at some point, venting damp air into the insulation. So I tore off all the ceiling drywall and exterior drywall, removed insulation, cleaned things up, and brought both my ceiling and exterior wall in 2″ to allow more insulation and increase the R-value. I also did a bang-up job on insulating my attic with brand new insulation using insulation chutes near the eaves. I replaced our tub and shower too as it had some cracks. I must admit this was a big job but I am glad I did it – mold is not something I want in my house! See removing black mold in drywall for details on this project.
There was mold above the ceiling, but I cleaned that region pretty thoroughly. The mold in the attic was partially due to the vent pipe disconnecting at some point. It is SO difficult to work in tight attics like this, but once the ceiling drywall was off, I could get at things.
We have not had really cold weather yet, but so far there is no mold. I think the key is insulating behind the drywall good enough so the drywall stays warm rather than cold once winter cold temps set in.
November 30 Update: We have had some freezing temps, but because the bathroom is so well insulated now, it is the warmest room in the house when the heat kicks on. This makes the walls and ceilings nice and warm so they dry up almost immediately after a shower.
I think the days of bathroom mold are gone forever!
Its interesting to know that you do post quality posts. I liked it and have digg’d it as well. Thank you
