PEX and PVC Foundation Leak Repair in South San Francisco
Newer homes often feature PEX or PVC plumbing, which, while durable, can still develop foundation leaks due to ground movement or improper installation. FBL Plumbing has the tools and expertise to repair leaks in these plastic piping systems. We use correct fusion and solvent welding techniques to ensure strong, leak-proof connections, restoring the integrity of your plumbing system beneath your South San Francisco foundation.
Post-Tension Slab Leak Repair in South San Francisco
Many newer homes are built on post-tension slabs with steel cables under high tension. Cutting into these slabs requires care and scanning to avoid hitting a cable. We use ground-penetrating radar or other scanning methods before opening the floor. When risk is too high, rerouting the plumbing is usually the safer option.

Drain Line Leak Under Foundation in South San Francisco, CA

Repairs may involve tunneling, cutting the slab or pipe lining. We walk you through the trade-offs of each method.
Slab Leak Detection and Repair in South San Francisco
Slab leaks are common in homes built on concrete foundations, often caused by shifting soil or corroded pipes underneath. Our technicians use non-invasive methods like electronic leak detection and hydrostatic pressure testing to find these elusive leaks. Once located, we can perform targeted repairs, either by slab tunneling or direct access, minimizing disruption to your home. We work with various pipe materials, including copper, PEX, and PVC, ensuring a durable repair for your South San Francisco property.

Foundation Leak Repair Cost Comparison in South San Francisco, CA
Direct repairs are often the lowest upfront cost but involve breaking concrete and may need flooring repairs.
