Schluter Kitchen Remodeling: The West Covina Owner’s Guide
A full Schluter-system kitchen remodel in West Covina typically runs $14,000 to $45,000 installed, depending on layout, cabinet count, and how much waterproofing the existing room needs. We stock Schluter KERDI-BOARD, DITRA, and edge trim profiles on the truck, so most tear-out and rebuild work starts without a parts delay. Homeowners usually find us after water has crept behind failing tile or under a sink cabinet, or when a previous contractor skipped the waterproofing membrane altogether and the grout lines started cracking within a year.
You landed here because something in the kitchen is failing or you’re planning a remodel and want the waterproofing done right from the first day. Either way, the answer is the same: Schluter’s system works when it’s installed to spec, and most failures we see in West Covina are installation shortcuts, not product defects. Let’s get specific about what you have and what it costs to fix.
Which Schluter Models This Applies To

Schluter makes a family of waterproofing and uncoupling products, and the exact part matters. The big three in kitchens: KERDI-BOARD (rigid foam panels that replace cement board on walls and counters), DITRA and DITRA-HEAT (the orange uncoupling membrane that goes under tile floors), and the KERDI membrane system (fabric for seams, corners, and transitions). If you have DITRA-HEAT, you also have a heating cable and thermostat to consider when we quote the job.
How to identify what’s on your wall or floor: KERDI-BOARD panels are printed with the Schluter logo and a grid pattern. DITRA looks like orange plastic with a waffle texture on top. Edge trim profiles (the metal strip that waterproofs where tile meets the floor or counter edge) are stamped with a profile series name like RONDEC or QUADEC and a length in millimeters. When we quote a replacement, we match the series and finish, not just “a metal edge.” Aftermarket equivalents exist, but with waterproofing parts we install Schluter OEM because the warranty chain depends on system compatibility. For cabinets and counters in the same kitchen, we pair the Schluter structure with KraftMaid or Wellborn for cabinetry and Cambria or Silestone for surfaces.
One compatibility gotcha we see in West Covina homes: older kitchens built before Schluter systems were common often have cement board with no membrane. Schluter parts don’t retrofit onto a failed traditional install without tearing out to the studs first. If there’s rot behind the wall, that adds framing repair to the quote. We’ll open a small section and show you what’s behind the tile before we commit to a number.
Styles & brands we work with







Signs Your Schluter Kitchen Remodeling Is Failing
- Grout cracking along the counter line within two years. This usually means the substrate flexed under the tile because the uncoupling membrane was skipped or installed over an unlevel surface. The tile isn’t the problem; the support underneath is.
- Caulk peeling at the sink rim or backsplash corner. Water is getting behind the tile and the caulk keeps letting go because the surface behind it is damp. Eventually the drywall or backerboard swells and the tile loosens.
- A puddle that reappears under the sink cabinet days after a leak “fix.” The leak was patched, not stopped, or the cabinet floor was never waterproofed and is wicking moisture from below. We pull the toe kick and look before quoting.
- Warped baseboard or soft cabinet floor on an exterior wall. In West Covina, summer heat and winter rain cycles punish kitchens on slab foundations. Moisture migrates up through the slab if no vapor barrier was installed, and the first thing to show it is the cabinetry base.
- Loose edge trim that catches a dish towel. The profile was cut too long, notched poorly, or installed without enough thinset behind it. It’s a small part, but a loose trim means water is wicking behind the tile at floor level, where it stays hidden longest.

AfterReplacement Cost & What’s Included

In West Covina, a Schluter-system kitchen remodel runs $14,000 to $45,000 installed. A smaller kitchen or a partial rebuild (backsplash and floor only, keeping existing cabinets) lands between $9,000 and $20,000. Countertop replacement over a new Schluter substrate runs $2,000 to $6,500, and a dedicated backsplash install with KERDI waterproofing runs $800 to $2,500. If the island needs rebuilding, add $3,000 to $10,000 depending on plumbing and electrical.
Every quote includes the written price before work starts, the Schluter materials, labor, haul-away of the old install, and the 365-Day Done Right Promise. If the waterproofing or tile work fails within a year, we’re back at no charge. That’s in writing on every kitchen remodel we quote, not a verbal promise. The price range exists because a 90-square-foot galley kitchen and a 250-square-foot open kitchen with an island are different projects, and we don’t pad quotes to cover unknowns. We open the wall, see what’s there, and then write the number.
DIY or Call Us?
You can safely remove cabinet doors, drawer fronts, and hardware, and you can clean grout or recaulk a visible seam. What you shouldn’t do is pull tile to “check what’s behind it.” Schluter systems fail when the waterproofing layer is compromised, and opening that layer without sealing it back correctly is how a $200 repair becomes a $4,000 floor rebuild. Water travels faster than most homeowners expect, especially in West Covina’s dry summers when the slab is warm and pulls moisture inward.
The honest answer: if you see cracked grout, loose trim, or water stains, call us at (341) 217-4204. We’ll inspect it, show you what we found, and give you the written price to fix it before any work starts. You don’t have to commit to a full remodel to get the answer.
FAQs

A properly installed Schluter KERDI and DITRA system should last 20 to 30 years in West Covina conditions. The limiting factors are moisture exposure, substrate movement, and whether the original installer followed the manufacturer’s thinset and seam requirements. Call (341) 217-4204 if you suspect an install was rushed, and we’ll tell you straight what’s failing and what isn’t.
Some parts can. Loose edge trim can be reset, a small membrane tear behind the sink can be patched with a KERDI patch, and a cracked tile can be swapped if you have spares. But if water has been sitting behind the assembly for months, the substrate and framing usually need replacement. We’ll open a small inspection hole and show you before quoting anything.
Most full-kitchen Schluter remodels in West Covina run 3 to 6 weeks from tear-out to final grout. Backsplash-only work is 2 to 3 days. The waterproofing cure times are non-negotiable, and we don’t cut them short; that’s exactly how hidden failures start. We’ll give you a written schedule when we quote.
Yes. We carry KERDI-BOARD in common thicknesses, DITRA and DITRA-HEAT membrane, KERDI band and corners, and RONDEC and QUADEC edge trim profiles. For non-standard profiles or custom finishes, we order direct and install within the week. Call (341) 217-4204 and we’ll confirm the part before we arrive.
