Slab leak repair in Sherman Oaks uses four main methods. The right choice depends on your pipe condition, leak location, and how long you plan to stay in the home.
Our repair methods include:
Spot repair fixes one damaged pipe section by opening a small area of the concrete slab. We mark the leak location, cut an opening under one square foot, remove the damaged pipe section, install new copper or PEX, pressure test, and patch the slab.
This method is best for a single leak on plumbing under 30 years old. It is the fastest and cheapest option. The trade-off is that spot repair does not fix the rest of the pipe, so if your home has aging galvanized or copper lines, a second leak often follows within a few years.
Typical cost in Sherman Oaks: $500 to $2,000
Time on site: 4 to 8 hours plus 24 to 72 hours for concrete cure
Pipe rerouting runs a new water line above the slab, bypassing the leaking pipe entirely. We cap the old line under the concrete and run new PEX or copper through walls, ceilings, or the attic to reach the same fixtures.
This method works best when the leak sits under expensive flooring like hardwood, marble, or stone, or when the leak location is hard to reach. Rerouting keeps your floor intact. The trade-off is small drywall patches in the ceiling or walls where the new line runs.
Typical cost in Sherman Oaks: $1,500 to $4,000 per line
Time on site: 1 to 2 days
Trenchless pipe lining coats the inside of the pipe with epoxy resin, sealing pinhole leaks without cutting concrete. A liner is pulled through the pipe and cured in place, forming a new pipe wall inside the old one.
This method is best for pipes that are structurally sound but leaking at small points. It works for both supply and drain lines. The trade-off is that lining does not work on badly corroded pipes or on breaks larger than a pinhole. We inspect with a video camera first to confirm that the lining is a fit.
Typical cost in Sherman Oaks: $80 to $250 per linear foot
Time on site: 1 to 2 days
Whole-home repiping replaces every water line in the home with new PEX or copper. Old lines under the slab are capped and abandoned. New lines run through walls, ceilings, and the attic.
This method is best for homes with pipes over 50 years old, homes that have already had two or more slab leaks, or homeowners who want to solve the pipe problem permanently. A full repipe comes with a lifetime warranty on materials and workmanship.
Typical cost in Sherman Oaks: $4,000 to $15,000
Time on site: 3 to 7 days
Sewer-side slab leaks need drain repair methods, not supply-line fixes. A leak in the sewer or waste line under your slab calls for a different approach. We start with a video pipe inspection to map the damage. From there, we choose between spot repair, trenchless sewer repair, or full replacement based on pipe condition.
