Commercial Wall Waterproofing in Lakewood
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 limit downtime. We also repair the plumbing behind those walls when leaks are discovered.

Exterior Foundation Waterproofing in Lakewood
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most effective 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 are a constant consideration in Southern California, and seismic straps and flexible connectors help keep water and gas lines intact during shaking. Proper drainage solutions, such as French drains, are also integrated to divert water away.
Sump Pump Installation and Repair in Lakewood, CA
Sump pumps are a key 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 correctly so water does not circulate back toward the foundation.

We use durable materials and proven techniques to provide lasting protection, reducing the chance of future repairs. Our goal is to deliver value and confidence.
Drainage System Integration in Lakewood, CA
Effective walls waterproofing often requires a solid 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 Lakewood, CA properties, so water is efficiently managed and moved away from your home's vulnerable areas.
Crawl Space Encapsulation in Lakewood
Crawl space encapsulation involves sealing the crawl space entirely with heavy-duty vapor barriers and often includes a dehumidifier. This not only waterproofs the walls but also controls humidity, preventing mold growth and wood rot in the crawl space. Intense sun breaks down exposed plastic pipe, sprinkler parts, and outdoor fittings, so they wear out faster than indoor plumbing. An encapsulated crawl space can significantly improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use durable, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.
Laundry Room and Utility Wall Waterproofing in Lakewood, CA
Washing machine hoses, utility sinks and water heaters can all leak into nearby walls. We replace burst-prone rubber hoses with braided stainless hoses and install leak pans and shutoff valves. Walls around water heaters and laundry boxes can be sealed to resist water damage. These small upgrades head off costly drywall repairs.

Interior Walls Waterproofing in Lakewood, CA
Interior walls waterproofing focuses on managing water that has already penetrated 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 effectively stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and is suitable where exterior access is limited.

Frequently Asked Questions About Walls Waterproofing in Lakewood
Shower wall waterproofing with a membrane system usually 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 generally ranges from $2,500 to $8,000.
Yes. Our workmanship is warrantied, and many membrane systems carry their own manufacturer warranty when installed correctly. We explain the coverage in your written estimate.
While minor DIY fixes like patching small cracks are possible, complete 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.
We use a range of high-performance waterproofing membranes and coatings depending on the application and foundation type. These can include liquid asphalt-modified polyurethane, rubberized asphalt membranes, bentonite clay systems, and crystalline coatings. Brands often include well-known names known for their durability and effectiveness in preventing water penetration.
Damp proofing is a less robust solution, typically a spray-on asphalt coating that resists soil moisture but isn't designed to withstand hydrostatic pressure. Waterproofing uses stronger membranes, coatings, or drainage systems specifically engineered to prevent liquid water from entering, even under pressure. For basements or crawl spaces in areas with high water tables or heavy rainfall, waterproofing is essential.
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 a few days.
For extensive walls waterproofing projects that involve excavation, significant structural changes, or changes to drainage systems, a permit from the Lakewood building department may be required. We will advise you on any required permits and help with the application process so all work complies with local codes.
Interior waterproofing addresses water after it has entered the foundation, usually managing it with sealants and drainage systems inside the basement or crawl space. Exterior waterproofing prevents water from reaching the foundation walls in the first place, usually by excavating and applying membranes or coatings to the outside of the foundation.
