Tamko Kitchen Remodeling: The Jacksonville Owner’s Guide
Tamko kitchen remodeling in Jacksonville typically runs $14,000 to $45,000 installed, and the work usually takes three to six weeks depending on cabinet lead times, countertop fabrication, and what we find behind the walls once demo starts. If you’re reading this, you’ve likely discovered that your Tamko product line, whether it’s decking, waterproofing membrane, or the kitchen surfaces built around it, has aged differently than the rest of the room, and you’re trying to figure out what actually needs replacing and what can stay. Graham Stein and our crews see this regularly in Jacksonville: a kitchen where the bones are sound but the Tamko-related underlayment or flashing work has failed, forcing a partial or full rebuild of the surrounding space. We stock common Tamko-compatible materials on the truck, and we give a written price before any work starts, so you’ll know exactly what this costs before you decide anything.
Key Takeaways
- Tamko kitchen remodeling in Jacksonville: $14,000 – $45,000 installed, with small-scope work starting around $9,000.
- We’re an independent Jacksonville remodeler, not affiliated with Tamko, but we work with Tamko-compatible materials daily and can match your existing setup.
- Florida humidity and Jacksonville’s wet summers shorten the lifespan of kitchen underlayment and flashing products faster than in dry climates.
- A written price comes before any work starts, and our 365-Day Done Right Promise covers the finished project.
Which Tamko Models This Applies To
Tamko is best known in kitchens for waterproofing membranes, underlayment, and substrate products that sit underneath tile, stone, and luxury vinyl surfaces, though some Jacksonville homes have Tamko decking materials repurposed into kitchen adjacent spaces like breakfast nooks or mudrooms. The compatibility question that matters most is this: whether your Tamko product was rated for interior use, exterior exposure, or both. Interior-rated Tamko underlayment products are not designed for the moisture swings a Jacksonville kitchen sees, and we have walked through Avondale Craftsman bungalows where the wrong product was installed years ago and is now quietly failing under the tile.
Identifying what you have takes a few minutes. Look for the manufacturer stamp on the exposed edge of any membrane or board, or check the underside of a removed kickplate or vents. Tamko products carry lot codes and product identifiers, not just brand names, and matching the product name and series matters more than matching the Tamko logo. When a homeowner brings us a model number we can usually tell within one visit whether we are matching OEM equivalent material or whether a better-suited current generation product would serve the kitchen longer. For kitchen remodeling in Jacksonville, we generally recommend a current interior-rated waterproofing system like Schluter under tile, with Tamko’s exterior products reserved for actual outdoor transitions like a covered porch off the kitchen.
We are an independent service provider, not affiliated with Tamko, but we stock Tamko-compatible materials and can work with nearly any product line already in your home. We also work regularly with KraftMaid, Cambria, and Silestone on the finish side, so the parts matching happens alongside the full remodel rather than as a separate puzzle.

Signs Your Tamko Kitchen Remodeling Is Failing
- Grout cracking along counter seams and floor edges. This usually means the substrate or underlayment has moved, softened, or compressed. Water has been finding its way in, and the rigid surface above no longer has a stable base.
- A musty smell that comes and goes, especially after rain. In Jacksonville, that smell near the kitchen exterior wall often means the waterproofing layer or flashing has failed and moisture is wicking in from outside. The Tamko layer may look fine from above, but it is compromised underneath.
- Tiles that sound hollow or shift slightly underfoot. A hollow sound means bond failure between the tile, the mortar, and the underlayment. That bond rarely fails first; it is usually the substrate degrading underneath the membrane.
- Discoloration or soft spots around the sink base or dishwasher opening. Water intrusion at the plumbing penetrations is the most common entry point we see on kitchen tear-outs in Jacksonville. If the underlayment near those openings is swelling or darkening, the membrane has been compromised.
- The surrounding cabinet bases show swelling or black staining at the bottom. This means water has bypassed whatever waterproofing layer was installed and is now wicking up through the wood. Repairing the cosmetic surface without addressing the Tamko layer underneath just shifts the problem a few months down the road.

AfterReplacement Cost & What’s Included
A full Tamko-related kitchen rebuild in Jacksonville runs $14,000 to $45,000, and the range depends on three things: how large the kitchen is, whether the failing substrate is confined to one zone or spread under the whole floor, and what finish materials you choose to go back in. A smaller scope, like re-waterproofing and retiling a section around the sink, falls into our small kitchen remodel range of $9,000 to $20,000. Countertop replacement alone lands at $2,000 to $6,500, and cabinet installation at $4,000 to $13,000 if the water damage climbed into the base cabinets.
Every line item is named before work begins. That means the membrane or underlayment product by name, the mortar, the tile or surface material, the labor broken into stages, and the dumpster and debris removal. We don’t use allowance line items that quietly grow. The written price covers shoe covers, drop cloths, and a photo of the clean-up before the crew leaves, and the 365-Day Done Right Promise means if something is not right after the job is complete, we make it right. Graham writes every scope in plain language; materials listed by name, labor in stages, so you can read the estimate without calling to ask what anything means. If you need a sharper number, call (904) 643-6243 and we will walk the kitchen with you.
DIY or Call Us?
There are a few things worth checking yourself. Pull the lower drawers out and look at the cabinet bases with a flashlight. Check for soft or swollen edges at the toe kicks. Run your hand along the wall behind the sink for damp spots. These observations help you describe the problem accurately and help us price the repair fairly before we arrive. What you should not do is pull up a corner of the membrane or start cutting into the underlayment to “see how far it goes.” Once the waterproofing layer is opened, Jacksonville’s humidity starts working on the exposed substrate immediately, and a small exploratory cut becomes a much larger repair.
If the layer itself needs replacement, this is not a weekend project. Getting the new membrane to bond correctly, tying it into the existing flashing at the exterior wall, and setting the tile above it properly requires experience with Jacksonville’s specific moisture conditions. Our crew does this regularly, and we would rather give you a straight answer over the phone first. Call (904) 643-6243 and describe what you are seeing. We will tell you what is likely happening and whether it needs a full kitchen remodeling scope or something more contained.
FAQs
In a dry interior, these products can last decades, but Jacksonville kitchens with high humidity, frequent cooking moisture, and the occasional plumbing leak usually see meaningful degradation in 10 to 15 years. Exterior transitions, like a slider to a covered porch, fail faster because of direct rain exposure. If your kitchen is over a crawl space that traps moisture, subtract a few years from that number. Call (904) 643-6243 and we can tell you whether the age you are seeing is normal or accelerated.
Sometimes yes, if the damage is contained to one area like under the sink or behind the dishwasher. We cut out the compromised section, install a compatible piece with proper seams, and retile that zone. If moisture has spread under the whole floor or up the walls, a patch job will only fail again, usually within a year or two. We will show you what we found and write the scope based on what the tear-out reveals.
A contained repair around the sink or dishwasher usually takes two to four days including tile work. A full kitchen remodel with new underlayment, cabinets, countertops, and finishes runs three to six weeks depending on material lead times. We name the day each stage happens in the written scope, so you know the dumpster date and the quiet days before we start.
We carry common Tamko-compatible membranes and underlayment sizes on the truck, along with the seam tapes and mortars needed to tie into the existing layer correctly. If your kitchen needs a specific series or a material we don’t stock, we order it by name and give you the arrival date before any demo happens. Call (904) 643-6243 with your model number or a photo of the stamp, and we will confirm compatibility before scheduling anything.
