Bathroom mold, explained
Surface Spots or Something Behind the Tile in Your Lake Mohegan Bathroom?
Every bathroom mold call falls into one of two buckets. Some of it is surface growth on grout lines and caulk, feeding on body oils and soap scum, and a good cleaning handles it. The harder cases are growing out of sight, in the wall behind the tub surround or in the subfloor, kept damp by a cracked shower pan liner, a dripping valve body or a toilet seal that's been seeping for a long time.
People fight caulk mold for years without winning. When the growth is inside the bead, no spray will reach it; the old silicone gets sliced out with a razor, the gap is dried and treated, and new caulk goes in. Overhead, the ceiling above the shower collects condensation when the fan is too small, gets shut off right away, or blows into the attic rather than through an exterior cap.
Older tub surrounds often hide paper-faced drywall behind the tile, and paper is mold food once water gets past the grout. That's why Bathroom Mold Removal in Lake Mohegan so often involves a plumber and a remediator working the same job.
