Waterproofing for Older Homes in Long Beach, CA
Older homes, especially those built before modern waterproofing standards, are especially prone to water intrusion. Copper pinhole leaks and corroded cast iron drains are common repair calls in homes that are now several decades old. 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.

Basement Wall Sealing in Long Beach, CA
Basement wall sealing is a key part of walls waterproofing. Intense sun breaks down exposed plastic pipe, sprinkler parts, and outdoor fittings, so they wear out faster than indoor plumbing. 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, healthier environment in your Long Beach, CA basement.
Waterproofing Costs vs. Repeat Water Damage in Long Beach, CA
Waterproofing a shower or wall costs far 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 side by side.
Laundry Room and Utility Wall Waterproofing in Long Beach, 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 prevent costly drywall repairs.
Foundation Crack Repair in Long Beach
Even small cracks in your foundation walls can allow water to seep into your basement or crawl space. Our walls waterproofing service includes foundation crack repair using specialized epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks promptly in Long Beach homes is crucial to avoid larger, more costly structural issues.
Drainage System Integration in Long Beach, 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 Long Beach, CA properties, so water is efficiently managed and moved away from your home's vulnerable areas.
Below-Grade and Basement Wall Waterproofing in Long Beach
Copper pinhole leaks and corroded cast iron drains are frequent repair calls in homes that are now several decades old. Wherever a home has a basement or below-grade walls, heavy rain and snowmelt can push water through foundation walls and cracks. We seal cracks with injection products, apply interior or exterior waterproofing and install drainage where needed. A sump pump may be added if groundwater builds up.

Foundation Crack Repair & Sealing in Long Beach
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 permanently. 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 Long Beach
The cost of walls waterproofing in Long Beach, CA can vary widely, 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 affect the final price. We provide detailed, upfront quotes after a thorough inspection.
For extensive walls waterproofing projects that involve excavation, significant structural changes, or changes to drainage systems, a permit from the Long Beach building department may be required. We will advise you on any necessary permits and help with the application process so all work complies with local codes.
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.
A shower wall waterproofing project typically 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.
FKM 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.
Skilled DIYers can roll on liquid membranes, but mistakes at seams, corners and drains often lead to leaks. Shower pans also require correct slope and flood testing. Professional installation lowers the risk of hidden water damage.
Sprinklers and drip lines aimed at the house are the most common cause. Heavy storms and poor grading also send water toward walls. Masonry absorbs that water and leaves mineral deposits as it dries.
Yes, FKM 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 confidence about your investment. Our goal is your complete satisfaction and a dry, healthy home.
