Slab Leak Repair vs. Re-Route: Which Is Right for Your Home?

A slab leak repair decision is really three options: single-spot repair, re-route, or full line replacement. The right choice depends on access, floor finish, how many leaks you've had, and how long you plan to stay. Here's the honest breakdown.

Option 1: Single-spot slab repair

We open ONE area of slab — typically 12-18 inches across — directly above the pinpointed leak. We cut out the bad section of pipe, splice in new copper or PEX, pressure-test, then patch the slab. Total time: 4-6 hours typical.

When single-spot repair is right:

• The leak is in an accessible spot (closet, hallway, easy-to-cover area)
• It's the FIRST slab leak you've had
• The pipes are relatively young (under 30 years) and not failing elsewhere
• The floor finish is carpet, vinyl plank, or laminate (easy to patch)
• You want the cheapest, fastest option

Pricing

Vegas average: $650-$1,400. Detection runs separately at $350-$600.

Option 2: Re-route through wall or attic

Instead of opening the slab, we abandon the bad section under the foundation and run a new pipe through an alternate path — usually through a wall or up through the attic. The old leak just stops (the pipe is capped on both ends and left in place). Total time: 4-8 hours typical.

When re-route is right:

• The leak is under tile, hardwood, or expensive flooring you don't want disturbed
• The leak is in a hard-to-access spot (under cabinets, central in the room)
• The slab is in a busy area where opening it would disrupt your life
• You want a permanent fix that doesn't touch the concrete

Pricing

Vegas average: $850-$1,800. Slightly more than single-spot because of the added pipe routing and access work — but no slab patching means no visible repair scar.

Option 3: Full line re-pipe

If you've had two or more slab leaks in the same line — or the line is old galvanized or thin-wall copper that's clearly failing — replacing the entire line is the smart long-term move. We run new PEX-A or copper from the source to the destination (usually through walls and attic), bypassing the failing slab pipe entirely.

When full re-pipe is right:

• You've had multiple slab leaks already (means the whole line is going)
• The home is 30+ years old with original plumbing
• You see other symptoms — low pressure, rust-colored water, multiple pinholes
• You plan to stay in the home long-term and want to be done with leak chasing

Pricing

Vegas average: $1,800-$3,500 for a full hot-water line replacement. If the whole house plumbing is going, a whole-house repipe ($4,800-$9,500) is often a better value than chasing leaks year after year.

What your floor looks like after

• Single-spot repair (carpet): Usually invisible after professional patching. Carpet covers the spot.
• Single-spot repair (vinyl plank/laminate): One or two boards replaced. Usually unnoticeable.
• Single-spot repair (tile): One or two tiles replaced. Exact color match is hard — there will likely be a visible repair area.
• Re-route: Floor stays intact. Small drywall patches in walls or ceiling where new pipe was run.
• Full line re-pipe: Floor stays intact. More drywall patches than a simple re-route.

What about insurance?

Most Vegas homeowners' policies cover the water damage from a sudden slab leak. Some also cover the leak detection cost and a portion of the repair. We provide detailed leak reports, photos, and pressure test results — exactly what your adjuster needs to process the claim.

"My rule of thumb: if it's the first leak and the floor is forgiving, repair it. If it's the second leak on the same line, re-pipe it. Throwing money at single-spot repairs over and over is how people end up regretting it." — Matt, owner
