Electronic Pinpoint Detection
Acoustic and pressure tools locate the exact failure point in your slab before any concrete gets cut. No jackhammer guessing or open-and-look excavation.
Foundation Leak Experts
SFV Slab Leak Repair
Warm floor? Water meter spinning with everything off? You've got a slab leak. We fix it three ways and pull every permit.
TRUSTED BY HOMES & BUSINESSES ACROSS THE SFV
Overview
Pinpoint and fix leaks under your foundation. Spot, reroute, or full repipe.
A slab leak is a pinhole or break in a copper line buried in your foundation concrete. Water runs under the house 24/7. Bills double. Floors warm up. Mold starts. Eventually, the slab cracks. SFV homes from the 60s and 70s have copper running under slabs and a lot of those lines are at end-of-life right now.
What Does It Cost?
Three big variables drive the number: which repair path you pick (spot, reroute, or full repipe), slab access (where the leak is and what flooring covers it), and finish-flooring restoration after concrete cut and patch. We pinpoint first, then quote all three options side by side.

Spot Repair vs. Reroute vs. Repipe
Spot repair vs. reroute vs. repipe. Spot is cheapest if you’ve got one leak in a clear location. Reroute makes sense if the slab access is brutal or the line has had multiple leaks already. Full repipe is the right call if the home is on its third or fourth slab leak. At that point you’re paying for repairs faster than a repipe would have cost. We give you the honest call based on what we find. Not what’s most profitable for us.

Scope of Work
What's In Every Slab Leak Repair Call
Three Quoted Repair Paths
Spot repair, reroute, and full repipe all priced side by side. You see what each costs, what each disrupts, and what the long-term math looks like.
Concrete Cut And Patch
Where spot repair is the right call, we cut clean access, complete the repair, and patch concrete back. Finish-flooring restoration coordinates after.
Permits And Inspection
Slab repairs and repipes require permits in LA County and SFV cities. We pull the permit, schedule the inspection, and the paperwork stays with your property records.
Workmanship Warranty
All slab repair work carries a workmanship warranty in writing. If our repair fails, we come back and fix it. Honest backstop on a high-stakes job.
How It Works
Our Step-By-Step Process
- Step 1
Confirm And Pinpoint
First job is to confirm it's actually a slab leak and not a wall leak or a sewer leak masquerading as one. Tech runs a pressure test on the supply system to confirm a pressurized leak, then narrows by zone (hot vs cold). Acoustic listening through the slab and electronic line-trace tools pinpoint the exact spot, usually within a 12-inch radius. 1 to 2 hours on most homes. You stay quiet during acoustic listening (no music, no laundry, no footsteps in the work area). Tech marks the spot on the floor with tape so you see exactly where the cut would happen.
- Step 2
Three-Option Conversation
We sit at the kitchen table and walk through three repair paths side by side: spot repair (cut concrete, fix the section, patch back), reroute (abandon the slab line, run new copper or PEX through walls or attic), and full repipe (replace all supply lines in the home). You see what each option costs, how long the home is without water, what gets disrupted (flooring, walls, landscape), and what the long-term math looks like if the home has had slab leaks before. 30 to 60 minutes. We give you the honest call based on what we found, not what's most profitable for us. You decide. Take it home and think about it if you need to.
- Step 3
Permit And Access Prep
Once you approve, we pull the permit with the city or LA County. SFV jurisdictions usually issue same-day or next-day for residential slab work. Tech preps access: protect surrounding flooring with plastic and tarps, set up dust containment (slab cuts make a lot of fine concrete dust), shut and lock the water main, and stage tools and materials. 1 to 2 hours of prep before any concrete gets cut. You'll see plastic sheeting and zipper doors going up to keep dust contained. Move anything fragile out of the work zone before we start.
- Step 4
Execute The Repair
Spot repair: cut a roughly 2 by 2 foot opening in the slab with a concrete saw, excavate to expose the failed copper, cut out the bad section, replace with copper or PEX, pressure-test, and patch concrete. Reroute: cap the slab line at both ends, run new line through walls, ceiling, or attic, and tie into existing fixtures. Repipe: full home supply replacement over 2 to 3 days. 4 to 8 hours of no water during a spot repair, water restored by end of day on most reroutes, water restored at end of each day on a repipe. You'll hear concrete saws, jackhammers, and shop-vacs. Stay out of the work area.
- Step 5
Inspection, Patch, And Cleanup
City inspector comes out to sign off the repair before concrete patch goes back in. Permit gets stamped and stays with your property records on resale. Concrete patch matches the slab thickness and gets a smooth finish, ready for finish-flooring restoration (tile, hardwood, carpet) which is its own trade and runs separately. We coordinate flooring restoration through one point of contact so you're not chasing a second contractor. Cleanup includes shop-vac of all concrete dust, removal of plastic and tarps, and full walkthrough with you. Workmanship warranty in writing on the invoice. Total project 1 to 3 days for spot, 2 to 3 for reroute, 2 to 5 for full repipe.

FAQs
About Slab Leak Repair
-
Slab leak signs: warm spots on the floor, sound of running water with everything off, water meter moving with no fixtures on, unexplained mildew smell, and bill spike. Wall leaks usually show up as drywall staining or wet baseboards. Detection confirms which it is.
-
Most policies cover the resulting water damage but not the pipe repair itself. Some cover access (cutting and patching concrete) but not the repair. Read your policy. Call your adjuster first. Then call us. We can document for the claim.
-
Often yes, especially if the home has had a slab leak before. Rerouting through walls or attic gets that copper out of the concrete forever. Spot repairs leave the rest of the slab line still in service. Still aging. Still likely to leak again.
-
Spot repair: usually 4-8 hours of no water during the cut/repair/patch. Reroute: 1-2 days, often with water restored to most fixtures by end of day one. Full repipe: 2-3 days with water restored at end of each day.
-
Yes. Slab repairs and repipes require permits in LA County and most SFV cities. We handle the permit application, inspection scheduling, and sign-off. The paperwork stays with your property records.
