We've had mold/mildew growing on the shower tiles, mostly along the
floor of our shower since we bought the house in August. We clean it
up, but it eventually comes back. I've always thought this was because
the floor at the front of the shower does not properly angle towards
the drain, allowing water to pool there.
The fan is also probably inadequate for the bathroom and it's clear
there's at least some moisture problem as the curtain rod left by the
previous homeowner has rusted a bit.
We've also got some black spots on the ceiling.
When I went to remove the grout this weekend (some of the grout on the
floor had failed), I discovered the grout in that area where the water
pools was saturated and water had infiltrated back behind the tile. It
appears there's some mold growing in that space near the floor, but one
row of tiles up, I don't see any mold. I haven't removed any shower
floor tiles yet.
We've already come to the conclusion that we need to pull off all the
tiles, replace the backerboard and retile, or install an enclosure.
What I need to have some guidance on is whether we should have a
professional come in and look at potential mold issues, or if we'd be
safe in doing the removal ourselves until and unless we see obvious
signs of widespread mold infestation in there.
The spots on the ceiling are bugging me a bit, as well. I don't know if
that indicates the mold has infiltrated the drywall in the ceiling, or
if that's just surface.
Any help anyone can provide would be most appreciated. We're trying to
decide on a course of action and get to work as soon as possible.
