Quick answer: Franco BuildWorks remodels bathrooms in Highlands, TX (77562), where Gulf Coast humidity, aging mid-century plumbing, and the San Jacinto River floodplain drive the details.

Bathrooms in Highlands’s postwar homes
Most bathrooms we see in Highlands were built for a different era of plumbing: a single hall bath in a 1950s or 1960s home off Main Street or Thompson Road, a compact tub-shower, a mud-set tile wall that has served forty or fifty years, and a small window or a weak vent fan fighting the coastal humidity. These rooms were built solidly, but the waterproofing methods of that time have often reached the end of their life, and hidden moisture behind old tile is the single most common thing we uncover.
A bathroom remodel in these homes is really two projects: the visible one the homeowner wants, and the wet-area rebuild behind the tile that determines whether the new work lasts. We plan for both from the start rather than treating the second as a surprise.
Why the waterproof membrane matters more here
Highlands runs humid nearly year-round because of its position between the San Jacinto River and the ship channel, and a bathroom in this climate never fully dries out on its own. That makes the shower’s hidden waterproofing the most important part of the job. Tile and grout are not waterproof; water passes through grout over time, and what stops it from rotting the wall is the membrane underneath.
We build showers with a proper waterproofing layer, either a sheet or liquid membrane over the backer board with sealed seams and corners, or a foam board system, plus a correctly sloped pan to the drain. Backer board is the substrate, not the waterproofing, a distinction that gets skipped in cheaper work and shows up years later as a soft wall or a musty smell. In a climate this wet, doing that layer right is the difference between a shower that lasts and one that quietly fails.
- Waterproof membrane over backer board, seams and corners sealed
- Pre-sloped pan draining fully to the drain
- Backer board treated as substrate, never as the waterproof layer
Ventilation and mildew in a damp climate
In a lot of older Highlands bathrooms the exhaust fan is undersized, vents into the attic instead of outside, or was never there at all. In this humidity that guarantees mildew on the ceiling and grout no matter how well the shower is built. We size the exhaust fan to the room and duct it fully to the exterior so moisture actually leaves the house.
Material choices help too. We favor mildew-resistant, moisture-rated products for wet-area surfaces and paint, and where a homeowner is choosing between finishes we point out which ones fight this climate and which ones fight you in it.
Old plumbing, slab movement, and access
Behind the wall, mid-century Highlands bathrooms often carry galvanized supply lines that have narrowed with scale and cast-iron drains that may be corroded. A remodel is the natural time to address that while the wall is open, and we would rather show you the real condition than tile over it. In slab homes, the drain lines run through the foundation, so relocating a toilet or shower can mean cutting the slab, which we scope honestly because it changes the work considerably.
The Beaumont clay under Highlands moves seasonally, and that movement can crack a rigid tile floor over a slab. On bathroom floors we address that with the right underlayment and, where warranted, a crack-isolation or uncoupling membrane so slab movement does not telegraph straight into the new tile.
Flood history and aging in place
Because much of 77562 is in the floodplain and many homes here took water during Harvey and earlier San Jacinto floods, we design bathrooms with recovery in mind: materials on the lower walls and floor that tolerate moisture, and a build that is easier to dry out and repair than to demolish. It is a small shift in thinking that pays off in a community that has been through high water before.
Many Highlands homeowners are also remodeling to stay in a home they have had for decades. If aging in place is part of the goal, we can build in a curbless or low-threshold entry, blocking in the walls for future grab bars, and a bench, without making the room look clinical. We treat those as design choices, not afterthoughts.
Permits and how Franco works
Highlands is unincorporated, so bathroom permitting runs through Harris County rather than a city department, and the plumbing and electrical work should be handled by licensed trades. In the floodplain, larger structural changes can require review through the Harris County Engineering Department, and we point you to that office as the authority rather than guessing.
We are a service-area remodeler working out of the Houston area, and we try to keep a bathroom project honest and contained: protect the rest of an occupied home, sequence the work, and open the wall before we quote so the waterproofing and plumbing are based on what is actually there. We do not give a firm number sight unseen, and we would rather tell you a shower pan needs rebuilding than discover it later.
Bathroom Remodeling in Highlands: FAQ
How do I know my old shower was waterproofed correctly?
Usually you find out during demolition. In older Highlands homes we often see failed pans and moisture behind mud-set tile. Signs to watch for now are a musty smell, loose or hollow-sounding tile, and soft spots; those point to water getting past the grout.
Can you move the toilet or shower to a new spot?
On a slab home in Highlands, moving a drain usually means cutting the slab, which is doable but adds cost and time. On pier-and-beam homes there is access underneath and it is simpler. We scope it honestly once we see how your home is built.
Why does mildew keep coming back in my bathroom?
Highlands humidity plus weak ventilation is the usual cause. Many older bathrooms here have an undersized fan or one vented into the attic. Sizing the exhaust fan to the room and ducting it fully outside typically makes the biggest difference.
Is a curbless shower a good idea in an older home here?
It can be, and it helps with aging in place, but it depends on being able to recess the pan into the floor structure. On slab homes that takes planning. We will tell you whether your floor allows it before promising the look.
Do bathroom remodels in Highlands need a permit?
Permitting goes through Harris County since Highlands is unincorporated. Cosmetic work often does not require a county building permit, but plumbing and electrical should be done by licensed trades, and floodplain rules can apply to bigger structural changes.
