Moldy Grout: Surface or Symptom?

We meter-test first, so you pay for the cure — not guesses.

This page is the decision tree we walk through on site: the sniff test, the pick test, the meter readings, and what each result means for your wallet. Roughly half of Newington's 'moldy shower' calls end in regrout-and-seal; a quarter end in clean-and-seal; a quarter need rebuild work we price with photos. Whatever yours needs, you'll understand why before spending a dollar.

  • Free moisture mapping. Readings at tub line, corners, valves, niche — shown to you.
  • Surface mildew path. Regrout or clean-and-seal; hundreds, one day, done.
  • Wet-wall path. Targeted opening, dry, treat, rebuild on proper substrate.
  • Fan check included. Dead exhaust fans cause half of recurring 'mold' — we test airflow.
  • No scare tactics. Readings and photos, not horror stories. Ever.

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 black grout and the smell; we bring the meter and the truth — including when the truth costs less than you feared.

FAQ

Common questions

What does the moisture check involve?

Pin and pinless readings at the tub line, corners, valves and niche — ninety seconds, non-destructive, results shown to you on the spot. Free.

Surface mildew vs. wet wall — cost difference?

Surface: clean-and-seal ($250–$600) or regrout ($450–$2,000). Wet wall: targeted rebuild priced with photos, typically low thousands. The meter decides, not the sales pitch.

Is shower mold dangerous?

Mostly allergenic, occasionally worse for sensitive people — but the wall rot it signals is the real expense. Fix the moisture path and both problems end.

My fan runs — why still mold?

Running isn't venting: disconnected ducts, clogged grilles and under-sized fans are epidemic. We check actual airflow at every mold assessment, free.
