Waterproofing: the Invisible Half

Tile is the pretty 10%. This page is about the dry 90%.

Every failed surround we tear out in Cromwell tells the same story: decent tile over drywall, greenboard, or mastic that re-emulsified years ago. The tile did not fail — the wall behind it dissolved. Our rebuilds assume water WILL get past grout eventually, and manage it: cement board that doesn't swell, a bonded membrane on every wet surface, sealed fasteners, and silicone — never grout — at every corner and tub joint.

  • Cement board substrate. Won't swell, soften or feed mold when wet.
  • Bonded membrane. Paint-on or sheet membrane over every wet-area square foot.
  • Sealed penetrations. Valves, spouts and fasteners gasketed, not just grouted around.
  • Movement joints. 100% silicone at corners, tub line and ceiling — grout cracks there.
  • Photo documentation. You see the waterproofing before tile covers it. Always.

Cromwell notes

In Cromwell we photograph every membrane coat with that day's date: Cromwell's 80s subdivisions are all hitting surround age at once — the same yellowed unit in fifty houses on one street. Dry walls are a system, not a material — and the system is what our workmanship stands on.

FAQ

Common questions

What waterproofing do you use?

Cement board substrate, bonded membrane over all wet surfaces, sealed fasteners and penetrations, and 100% silicone at every change of plane. Photographed before tile covers it.

Is greenboard behind tile OK?

No — moisture-resistant drywall still fails under chronic wetting. Most Cromwell tear-outs we do are greenboard autopsies. We never tile over it.

Kerdi, RedGard, Hydro Ban — which is best?

All work when installed to spec; the installer matters more than the brand. We use sheet membrane in showers and paint-on for tub surrounds, per manufacturer coverage rates.

Do you warranty against leaks?

Our workmanship warranty covers the assembly we build — substrate, membrane, joints and seals. The quote states terms plainly; no weasel words.
