The grout is the last thing to fail. By then, the damage is already done. Riverview showers built between 2005 and 2020 are hitting their first renovation cycle — and what's behind those walls is almost never what the original installer promised.
A decade of daily shower use in a production-built Riverview home does predictable things to a builder-grade installation. The grout at the curb starts to crack and darken. The caulk at the floor-to-wall joint fails and water finds the seam. The back wall tile starts to feel slightly soft when pressed — the substrate behind it has been absorbing moisture through failed grout joints for years. By the time the homeowner calls for a remodel, the tile is often the least of the problems. What's behind it is what needs to be replaced.
Full demo is not optional when substrate condition is unknown. Tiling over a shower that's already showing moisture-related failure is a guarantee of another callback within two or three years. The only way to assess what's behind the original installation is to remove it. We do a substrate inspection during demo before any new material goes in — that's the only way to find active mold growth or rotted framing before it's covered up again for another decade. When we find it, we document it and communicate the scope before proceeding.
Murati handles the full corrective scope from demo through tile: tear-out and haul-off, substrate assessment and replacement as needed, cement board or foam backer, full liquid or sheet membrane, and tile installation with grout and sealant appropriate for the exposure level. The 1-year labor warranty covers what we build — and we build it so it doesn't need to be called on.
In Riverview homes built between 2005 and 2018 — particularly in communities along Boyette Road and in the 33578 zip code — we find the same pattern on demo: greenboard backing, no corner fabric, no curb waterproofing. The mold isn't always visible from inside the shower. It's in the wall cavity, behind the tile, where it's been growing since the grout first cracked. Most homeowners start the remodel conversation with tile selection — the look, the layout, the color. That's not wrong. But the decisions that determine whether the remodel holds up for 20 years are made before the tile is even selected: substrate type, membrane system, drain waterproofing, curb construction.
Riverview's specific challenge is that many homeowners doing their first real renovation don't know what was standard practice in production construction — and what was cut. When we explain that the original shower had no waterproofing membrane, some clients are genuinely surprised. The tile looked fine for years. What looked fine was the tile. The substrate behind it was managing moisture the way greenboard does: slowly, imperfectly, and eventually not at all.
The remodel conversation we have with clients is straightforward. We explain what we found during demo, what needs to be replaced and why, and what the correct rebuild looks like layer by layer. No surprise scope changes mid-project — we document what we find before any new material is ordered, and we communicate findings before we proceed. The 1-year labor warranty starts the day we finish.
We handle the full scope — demo, substrate assessment, membrane, and tile — with a written schedule, findings communicated before new material is ordered, and a 1-year labor warranty on the work. Serving communities across Riverview including Boyette Road, the 33578 and 33579 zip codes, and South Hillsborough County.
