Shower Pan Leak Repair and Waterproofing in Tustin, 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 confirm 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 proves the pan is watertight before tile.

Commercial Wall Waterproofing in Tustin
Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure. We waterproof commercial showers, mop sink walls and restroom wet walls with durable membranes. Work can be scheduled after hours to reduce downtime. We also repair the plumbing behind those walls when leaks are found.
Drainage System Integration in Tustin, CA
Lasting walls waterproofing often requires a robust drainage system to divert water away from your foundation. This can include interior perimeter drains that channel water to a sump pump, or exterior French drains that collect surface water. Our team designs and installs custom drainage solutions for Tustin, CA properties, so water is efficiently managed and moved away from your home's vulnerable areas.
Basement Wall Sealing in Tustin, CA
Basement wall sealing is a critical part of walls waterproofing. A warm, dry climate is the main factor for plumbing in Southern California, with long irrigation seasons and year-round demand on outdoor lines. We apply high-quality sealants to porous concrete and masonry walls to prevent moisture from wicking through and causing dampness, mold, or musty odors. This service can be performed alone or as part of a larger waterproofing system, offering a drier and healthier environment in your Tustin, CA basement.
Shower Wall Waterproofing in Tustin
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 reinforcement before new tile is set.
Sump Pump Installation and Repair in Tustin, CA
Sump pumps are a critical part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during flash floods. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed properly so water does not circulate back toward the foundation.
Waterproofing Costs vs. Repeat Water Damage in Tustin, CA
Waterproofing a shower or wall costs much less than repeated drywall, cabinet and flooring repairs. Ignoring moisture also invites mold, which can be expensive to remediate. A typical shower wall waterproofing project falls in the low thousands, while exterior block sealing varies with wall size. We give you a written quote so you can compare options clearly.

Foundation Crack Repair & Sealing in Tustin
Even minor cracks in foundation walls can allow serious water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points for good. This method fills the entire depth of the crack, restoring strength and preventing water penetration. We address both vertical and horizontal cracks, knowing that horizontal cracks can indicate structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and expensive future repairs.

Frequently Asked Questions About Walls Waterproofing in Tustin
Shower wall waterproofing with a membrane system typically runs $1,200 to $3,500 including demolition and backer board, not counting new tile. Exterior block wall sealing often costs $800 to $3,000 depending on size. Below-grade foundation waterproofing usually ranges from $2,500 to $8,000.
We use a range of high-performance waterproofing membranes and coatings depending on the application and foundation type.

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 make sure it stays that way.
FKM Plumbing works with reputable manufacturers known for high-quality waterproofing products. We commonly use products from brands like Xypex, Tremco, and Sika for their proven effectiveness and durability, from crystalline admixtures to elastomeric membranes and sealants. We select the best product for your foundation type and site.
Yes, FKM Plumbing stands behind the quality of our walls waterproofing services. We offer comprehensive 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.
While minor DIY fixes like patching small cracks are possible, full walls waterproofing is best left to professionals. It involves specialized knowledge of drainage, foundation mechanics, and proper material application. Improper DIY work can lead to ineffective results, wasted money, and worse water damage over time.
