Moldy Surround? Fix the Cause
Bleach treats the symptom. We remove the wet wall it grows on.
Musty smell when the shower runs hot? Soft spot at the tub line? Grout that crumbles when you pick it? Those are the three signs of a surround leaking into the wall, and we see them weekly across Newington. This page explains what we check, what remediation actually involves, and when a section repair suffices versus a full surround rebuild. Either way you get photos of what we found, not just a bill.
Newington notes
Original Newington tub walls are narrow — two short walls and a plumbing wall — which is why surround re-tiles here finish fast. The failure point is always the same: grout gone soft at the tub line and corners. Half of Newington's tubs are cast iron worth keeping; the walls around them are not. Surround-only re-tile is the town's sweet-spot job. 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.'
- 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.

Common questions
Most bathroom mold is allergenic rather than toxic, but it signals a wet wall cavity that rots framing and feeds worse growth. The wall matters more than the species — fix the leak path.
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.
