Exterior Foundation Waterproofing in Gilroy
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most reliable method for preventing water from entering the basement or crawl space. We use high-quality asphalt-modified polyurethane membranes or polymer-based coatings that resist hydrostatic pressure and soil movement. Earthquakes and hillside soil movement are real risks in Northern California, so flexible connections and seismic straps help protect plumbing from sudden movement. Proper drainage solutions, such as French drains, are also added to divert water away.

Commercial Walls Waterproofing in Gilroy
Beyond residential properties, FBL Plumbing also offers walls waterproofing services for commercial buildings in Gilroy. Protecting commercial basements, equipment rooms, and underground parking garages from water damage is vital to business operations. We understand the need for minimal disruption and efficient project completion for commercial clients. Our team works with property managers and business owners to implement robust waterproofing solutions that fit the demands of commercial structures and their code requirements.
Commercial Wall Waterproofing in Gilroy
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 Gilroy, CA
Effective 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 Gilroy, CA properties, so water is efficiently managed and moved away from your home's vulnerable areas.
Interior Walls Waterproofing in Gilroy, CA
Interior walls waterproofing focuses on managing water that has already passed through the foundation walls. This usually involves installing an interior drainage system, often called a French drain, along the perimeter of the basement floor. Water is collected and channeled to a sump pump, which then sends it safely away from the foundation. While not preventing water from entering the wall, it stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and is suitable where exterior access is limited.
Foundation Crack Repair & Sealing in Gilroy
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.
Plumbing Leak Behind Walls in Gilroy
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We locate 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 walls.

Crawl Space Vapor Barriers in Gilroy
Many homes in Gilroy have crawl spaces, which are very prone to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting prevents ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an effective way to control humidity and prevent wood rot.

Frequently Asked Questions About Walls Waterproofing in Gilroy
The cost of walls waterproofing in Gilroy, CA can vary a lot, typically ranging from $3,000 for interior crack sealing to $15,000 or more for extensive exterior foundation waterproofing with drainage systems. Factors like the size of the area, severity of water damage, chosen methods, and accessibility all influence the final price. We provide detailed, transparent quotes after a thorough inspection.
Walls waterproofing is a key 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.
Key signs you need walls waterproofing include damp or wet basement walls, visible mold or mildew growth, a musty odor in your basement or crawl space, efflorescence on concrete walls, cracks in the foundation, or standing water after heavy rains. Don't ignore these indicators, as they often point to ongoing water intrusion.
Absolutely. By preventing water intrusion through your walls, waterproofing greatly 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.
A shower wall waterproofing project usually takes two to four days, including drying time between coats. Exterior block sealing can often be completed in a day. Larger foundation jobs may take several days.
FBL Plumbing works with trusted 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 conditions.
Yes, FBL Plumbing stands behind the quality of our work. We offer comprehensive warranties on our walls waterproofing installations, covering both materials and labor. The warranty details will be outlined in your service agreement, giving you peace of mind about your investment. Our goal is your complete satisfaction and a dry, healthy home.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Gilroy may be required. Simple crack repairs usually do not need a permit. FBL Plumbing will help you determine if a permit is necessary for your project and assist with the application process if needed.
