Schluter Home Additions & ADU: The Fort Worth Owner’s Guide
If you’re planning a home addition or ADU in Fort Worth with Schluter waterproofing and uncoupling systems, the full project typically runs $45,000 to $130,000 for an addition, and $90,000 to $220,000 for a detached ADU. We install Schluter products as part of larger projects, and we keep the common Schluter profiles, KERDI membrane, and DITRA underlayment on hand for repair work when a tile assembly starts to fail. Most homeowners call us after water has already found its way past a compromised waterproofing layer, or when they’re mid-project and realize the wrong Schluter trim was spec’d for their floor-to-wall transition.
Here’s the honest picture: Schluter makes excellent products, but their system only works as well as the substrate and the installer’s attention to detail. In Fort Worth’s clay-heavy soil, slab movement is a real thing. If a DITRA membrane wasn’t laid with full mortar coverage, or a KERDI seam wasn’t overlapped the full 2 inches, water gets where it shouldn’t, and the failure often doesn’t show up for a year or two. By then, you’re not replacing a part. You’re rebuilding a shower pan or pulling up a floor.
Which Schluter Models This Applies To
Schluter doesn’t make a single “Home Additions & ADU” product. What they make is a system: KERDI and KERDI-BOARD for waterproofing showers and wet areas, DITRA and DITRA-HEAT for uncoupling floors from substrate movement, and a full line of metal profiles (Schiene, Jolly, Quadec, Rondec) that finish edges and protect tile corners. The part you’re dealing with depends on where the failure is.
The compatibility gotcha most Fort Worth homeowners run into is mixing Schluter profiles with tile thickness they didn’t measure. Schiene and Jolly come in specific heights that match specific tile thicknesses. If you buy the profile for 3/8-inch tile and your tile is 1/2-inch, the profile sits below the tile face and looks wrong. You need to know your tile thickness before you order. We also see DITRA-HEAT installations where someone used a non-Schluter thermostat or cable spacing that doesn’t match the system, which voids the Schluter warranty and creates cold spots in the floor. For aftermarket parts, thin-set mortar and grout don’t need to be Schluter-branded, but the membrane, corners, and pipe seals should be genuine Schluter. The corners and KERDI-KERECK pre-formed pieces are where off-brand substitutions fail first, because the fleece backing is what bonds to the membrane, and the fleece has to match.
Bradford Remodeling Co Fort Worth is an independent contractor. We’re not a Schluter dealer or affiliate. We buy from the same supply houses the tile shops use, and we specify genuine Schluter when the job calls for it.

Signs Your Schluter Home Additions & ADU Is Failing
- Water staining on the ceiling below a second-floor bathroom. This usually means a KERDI seam failed or was never properly bonded. The waterproofing layer is only as good as the overlap, and a 1-inch overlap instead of the required 2 inches is a slow leak waiting to happen.
- Efflorescence or dark grout lines at the bottom of a shower. Water is wicking up through the grout because the shower pan membrane isn’t sloping correctly, or the weep holes in a traditional drain are clogged. Schluter’s KERDI-DRAIN solves this when installed right, but we’ve pulled apart showers in Fort Worth where the drain flange wasn’t set level.
- Cracked tile in a straight line across the floor. That line is telling you the slab underneath cracked, and the DITRA membrane either wasn’t there or wasn’t bonded with full coverage. In Fort Worth, where summer heat and clay soil make slabs move, uncoupling is not optional. It’s the difference between a crack in the grout and a crack through the tile.
- Hollow-sounding tile when you tap it. This is a bonding failure. The thin-set didn’t transfer to the back of the tile or to the DITRA fleece. It might hold for years, or it might pop loose next week. Hollow tile in a shower is a water intrusion risk.
- Metal profile pulling away from the tile edge. Schluter profiles should be embedded in thin-set under the tile edge. If the profile is loose or lifting, the tile edge it’s protecting is exposed, and that edge will chip. In a bathroom, a lifted profile also gives water a path behind the tile.

AfterReplacement Cost & What’s Included
Replacing a failed Schluter component in Fort Worth is rarely a parts-only job. A single Schiene profile might cost $30, but cutting it out of a finished tile assembly and reinstalling it properly involves tile removal, thin-set prep, and grout matching. Here’s what we typically see:
| Scope of Work | Fort Worth Installed Price Range |
|---|---|
| Replace a Schluter profile in existing tile | $200 – $500 |
| Rebuild a KERDI shower pan and one row of wall tile | $1,500 – $4,000 |
| Full shower waterproofing redo (tear-out to re-install) | $4,500 – $12,000 |
| DITRA underlayment repair for cracked floor tile (small area) | $500 – $1,800 |
| New addition or ADU with full Schluter system in wet areas | $45,000 – $220,000 |
Every price from Bradford Remodeling Co Fort Worth is written down before we start, and it includes the Schluter parts, mortar, labor, and cleanup. No number moves at the door. If something is hidden behind the tile that changes the scope, we stop, show you, and put the new number in writing before we touch it. The work is covered by our 365-Day Done Right Promise: if the repair fails within a year, we come back and correct it at no charge.
DIY or Call Us?
Schluter parts are sold at tile suppliers and big-box stores, and Schluter publishes installation videos for everything they make. That’s fine for someone who has set tile before. The honest split is this: if you’re replacing a visible profile and you’re comfortable cutting out grout without chipping the tile, you can probably handle it. If the failure involves waterproofing, which means water behind tile, inside a wall cavity, or under a floor, do not open that up yourself. You’ll find mold, rotted subfloor, or worse, and you’ll be mid-demolition on a bathroom you still need to use. We’ve met too many Fort Worth homeowners who started a “small” shower repair on Saturday and called us Monday with half a bathroom in the driveway. For anything involving the waterproofing layer, the substrate, or tile removal around plumbing, call (682) 204-4897. We’ll come look, tell you what’s actually wrong, and hand you a written price before any work starts.
FAQs
A correctly installed Schluter KERDI shower system should last 30 to 50 years, because the membrane itself doesn’t degrade. What shortens that lifespan in Fort Worth is substrate movement, improper mortar coverage at seams, or someone punching holes in the membrane after installation. The product is durable. The installation is what usually fails.
In most cases, no. The fleece backing on KERDI needs clean, dry, unbroken membrane on both sides to form a bond, and once water has wicked into an open seam, the area around it is compromised. You can patch some small punctures with KERDI-FIX and a KERDI patch, but a true seam failure means opening the tile back up. Call (682) 204-4897 and we’ll tell you straight which situation you’re in.
A shower pan rebuild or waterproofing repair typically takes 3 to 5 working days, mostly because mortar and grout need cure time between steps. A profile replacement in an existing tile assembly is usually a single visit. We’ll give you the exact schedule in writing with your estimate.
We keep KERDI membrane, DITRA underlayment, inside and outside corners, pipe seals, and the common profile styles in standard sizes on our trucks. If you need a specific finish like brushed nickel Quadec in an unusual length, we source it from our local Fort Worth supplier, usually same day or next morning.
A full home addition with Schluter waterproofing in wet areas runs $45,000 to $130,000, and an ADU runs $90,000 to $220,000 depending on size, finishes, and site conditions. Smaller Schluter-specific repairs, like rebuilding a shower pan, fall between $1,500 and $4,000. We put every number in writing before work starts, so the quote you sign is the price you pay. Call (682) 204-4897 for a free estimate on your specific job.
