Shower Pan Leak Repair and Waterproofing in Temecula, CA
A cracked or poorly sloped shower pan often causes wet baseboards and stained ceilings below. We test the pan by plugging the drain and flooding it to verify the leak. Then we rebuild the pan with correct pre-slope, a new liner or bonded membrane and a properly clamped drain. A second flood test confirms the pan is watertight before tile.

Shower Wall Waterproofing in Temecula
Tile and grout are not waterproof on their own, so water reaches the backer board in every shower. If the walls were built without a proper membrane, moisture soaks into studs and drywall. We remove failing tile, install cement board or foam board and apply a membrane such as Schluter Kerdi, RedGard or Hydro Ban. Seams, corners and niches get extra attention before new tile is set.
Waterproofing for Older Homes in Temecula, CA
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Postwar tract homes are common in Southern California, and many still have original galvanized or copper supply lines and cast iron drains under the slab. Many older foundations may lack adequate exterior drainage or proper sealing. We specialize in assessing and upgrading waterproofing systems for these properties, often combining exterior excavation with interior drainage solutions. We respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.
Plumbing Leak Behind Walls in Temecula
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We find the leak with moisture meters, thermal imaging and pressure tests. The damaged section of pipe or valve is replaced, and wet drywall is cut out and dried. Once the cavity is dry, we restore the wall and seal any wet-area surfaces.

Frequently Asked Questions About Walls Waterproofing in Temecula
The cost of walls waterproofing in Temecula, CA can vary significantly based on the method used, the extent of the damage, and the size of your foundation. Basic crack sealing might range from $300 to $800 per crack, while a full exterior foundation waterproofing project could be $8,000 to $20,000 or more. Interior drainage systems with a sump pump typically fall between $4,000 and $12,000. We provide transparent, itemized quotes after a thorough inspection.
Waterproofing prevents the moisture mold needs to grow. Existing mold should be removed and the area dried before sealing. We remove affected materials when needed and recommend remediation for larger growth.
Look for bubbling paint, soft drywall, stained baseboards and musty odors. White crust on block or stucco walls is another sign of moisture moving through. Loose tiles or cracked grout in a shower also mean water is getting behind.
Absolutely. By preventing water intrusion through your walls, waterproofing significantly reduces the moisture and humidity levels in your basement or crawl space. This creates an environment less friendly to mold and mildew growth, improving air quality and protecting your belongings from moisture damage.
Yes, FKM Plumbing stands behind the quality of our walls waterproofing services. We offer full warranties on our materials and workmanship, giving you peace of mind. Warranty details will be provided with your project proposal, spelling out the coverage and duration of your waterproofing system.
Yes. Our workmanship is warrantied, and many membrane systems carry their own manufacturer warranty when installed correctly. We explain the coverage in your written quote.
Walls waterproofing is a primary step in preventing future mold growth by eliminating the moisture source. However, it does not remove existing mold. If mold is already present, it will need to be professionally remediated before or along with the waterproofing process. Once the area is dry and mold-free, waterproofing will help keep it that way.
The duration of a walls waterproofing project varies significantly. Smaller jobs like interior crack sealing might take a day or two, while extensive exterior waterproofing with excavation and drainage system installation could take several days to over a week. We'll provide a clear timeline during your consultation.
