Supply Line Leak Repair in South Gate
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 add softeners or scale filters. Water chemistry affects how fast copper corrodes, and older galvanized lines frequently 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.

Drain and Sewer Pipe Leak Repair in South Gate, 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.
Water Damage Assessment in South Gate, CA
Before any repair, our team conducts a thorough water damage assessment to identify the source and extent of your basement leak. This includes inspecting for mold growth, structural concerns, and damaged finishes. Our complete approach ensures that all related issues are addressed for a full restoration of your South Gate basement.
Wall and Slab Seepage Repair in South Gate
When water enters through foundation walls or the slab joint, the cause is usually surface water pooling against the house. 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. Dense or saturated soil can hold water near the foundation instead of letting it drain away. We seal penetrations where pipes pass through the wall and can install interior drain channels that carry seepage to a sump. We also suggest grading and gutter changes when outside water is the root cause.
Commercial Basement Waterproofing in South Gate
Commercial properties in South Gate also face the risk of basement leaks, which can damage inventory and equipment and disrupt business operations. FKM Plumbing offers specialized commercial basement leak repair services, providing robust and scalable solutions tailored to the demands of business establishments. We minimize downtime and protect your assets with prompt, professional service.
Floor Drain and Backwater Valve Repair in South Gate
A basement floor drain that backs up during heavy use or a storm usually 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 without trouble.
Emergency Basement Flooding Response in South Gate
A burst pipe or a failed sump during a storm can put inches of water on the floor in minutes. Call us and shut off the main water valve if you can do so without risk. We stop the leak, pump out standing water from the plumbing failure and make the system safe. We can also point you to drying and restoration crews when the damage calls for it.

Waterproofing for Older Southern California Homes in South Gate, CA
Many older homes in South Gate and across Southern California were not built with modern waterproofing techniques, making them more prone to basement leaks. Copper pinhole leaks and corroded cast iron drains are common repair calls in homes that are now several decades old. FKM Plumbing focuses on retrofitting older foundations with current solutions, addressing issues like failing mortar, porous concrete, and inadequate drainage. We preserve the integrity of historic structures while providing modern protection.
