Basement Leak Repair in Los Angeles, CA

Proven Basement Leak Repair Services in Los Angeles, CA

Supply Line Leak Repair in Los Angeles

Water lines that run along basement ceilings and walls can leak at fittings, valves or pinholes. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California install softeners or scale filters. Water chemistry affects how fast copper corrodes, and older galvanized lines often rust from the inside. We locate the leak, replace the damaged section with copper or PEX and pressure test the repair. If the line shows widespread wear, we'll tell you whether a partial repipe makes more sense.

Floor Drain and Backwater Valve Repair in Los Angeles

A basement floor drain that backs up during heavy use or a storm typically points to a blockage or a failed trap. We clear the drain, check the line to the main sewer and replace cracked traps and covers. Installing a backwater valve stops sewage from pushing back into the basement if the main line surcharges. We set the valve where it can be serviced easily.

Sump Pump Installation and Repair in Los Angeles

A properly functioning sump pump is crucial for preventing basement flooding, especially during heavy downpours. FKM Plumbing provides professional sump pump installation, repair, and maintenance services. We make sure your pump is correctly sized and installed to handle the water volume, giving you peace of mind.

Drain and Sewer Pipe Leak Repair in Los Angeles, CA

Cast iron drain stacks in older homes crack and scale with age, and plastic joints can separate if a line was poorly supported. These leaks often show up only when an upstairs fixture runs. We run water through each drain while watching the basement, then confirm the crack with a camera. Repairs range from a single section swap to replacing an entire stack with PVC or ABS.

Hydrostatic Pressure Management in Los Angeles, CA

Heavy rain can lead to significant hydrostatic pressure against basement walls, forcing water through concrete. When heavy winter storms do arrive, runoff can overwhelm yard drains and storm systems, and burn areas can send mud into low-lying homes. FKM Plumbing installs interior and exterior drainage systems, including French drains and weeping tile systems, to relieve this pressure. We also install sump pump systems to efficiently remove collected water, keeping your basement dry.

Exterior Waterproofing in Los Angeles, CA

For a more complete solution, we offer exterior waterproofing, which involves excavating around your foundation, applying a waterproof membrane, and installing drainage boards. This method creates an watertight barrier on the outside of your basement walls, providing superior protection against water intrusion. Hot inland summers push water heaters and pool plumbing hard, while coastal salt air can corrode exposed metal fittings.

Foundation Crack Repair in Los Angeles

Foundation cracks are a common entry point for basement water leaks, especially in homes built on soil that swells and shrinks. Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, wet carpet, or an unexplained jump in the water bill. We utilize epoxy and polyurethane injection techniques to seal these cracks, preventing water infiltration and reinforcing your foundation. Our methods are matched to the specific type and size of the crack, ensuring a durable repair.

Water Heater and Appliance Leak Repair in Los Angeles, CA

Water heaters, softeners and laundry machines are often installed in basements, and their leaks pool fast. A dripping T&P valve, a corroded tank bottom or a split washer hose are common culprits. We repair or replace the failed part and install drain pans and leak sensors to catch future problems early. If a tank has rusted through, we can replace it the same day in most situations.
