Moldy Surround? Fix the Cause
Bleach treats the symptom. We remove the wet wall it grows on.
If your Bristol tub surround grows black grout no cleaner defeats, the problem is behind the tile, not on it: water wicking through failed grout into drywall or greenboard that was never meant to get wet. Painting over it with 'mold paint' or re-caulking buys months. The fix is a half-day of honest demo — open the wet section, dry and treat the framing, rebuild on cement board and membrane — then tile that never feeds mold again.
- Moisture check first. Meter readings at the tub line, corners, valves and niche before any quote.
- Open only what's wet. Targeted demo — we don't gut dry walls to pad the job.
- Treat the framing. Dry, treat and document studs; replace only what's compromised.
- Rebuild dry. Cement board + membrane + sealed fasteners, so it can't recur.
- Epoxy grout option. Non-porous joints that starve surface mildew going forward.
- Ventilation advice. Half of 'moldy baths' are really exhausted-fan failures — we check.

Bristol notes
Bristol tub walls are the textbook case: 50-year-old 4x4 tile, missing grout at the tub line, a cracked corner tile letting water behind. Shower floors in the capes are small enough to re-tile in a day. Bristol's capes have the smallest shower floors in the footprint — a one-day re-tile that transforms the whole bath. Bring us the smell and the stains; we will bring the meter and tell you the truth, including when the truth is 'just re-caulk it.'
Common questions
Only what's wet. Moisture readings map the damage; dry sections can stay. About half our mold calls need full rebuilds, half need section repair plus re-caulk and ventilation fixes.
Typically $200–$600 for contained treatment during a rebuild: demo of wet board, drying, treatment and documentation. Extensive framing damage is priced with photos first.
Not from the wall — cement board and membrane don't feed mold, and silicone joints don't wick. Keep the fan running and squeegee glass; we'll show you the 30-second routine.
Mold calls jump the queue — usually within 48 hours in Bristol. The moisture check and honest verdict are free.
