What is a slab leak reroute?
A slab leak reroute fixes a leak by bypassing it. The plumber caps the leaking line under the slab and installs new pipe, usually PEX, through the walls or attic to the same fixtures. Your floor and slab stay as they are, and the old pipe stays in place, unused.
Rerouting is a common way to fix slab leaks in North Texas. It avoids the dust and noise of cutting concrete, and you do not need to match tile or wood afterward. The new line sits above the slab where a future problem is easy to reach.
When a reroute beats a spot repair
Choose a reroute when the leak is under costly flooring, under cabinets or a tub, when your slab is post-tensioned, or when the pipe has leaked before. A spot repair wins only for a first leak in an easy spot under floors you can patch.
| Your situation | Better choice | Why |
|---|---|---|
| Leak under tile you can match | Spot repair | Lowest cost, one small patch |
| Leak under wood, stone or cabinets | Reroute | Avoids replacing expensive flooring |
| Post-tension slab | Reroute | No risk of cutting tension cables |
| Second leak on the same line | Reroute | Old pipe is likely failing elsewhere |
| Three or more leaks | Repipe | Whole system is wearing out |
How a reroute is done
A reroute takes four steps: map the line, open small access points in walls or ceilings, run and connect new pipe, then test and patch. Most single-line reroutes in Little Elm homes take one to two days, including drywall repair.
- Map the routeThe plumber plans the shortest path from the supply to each fixture, through the attic or walls.
- Open accessSmall cuts in drywall at each connection point. Most single-story homes route through the attic.
- Install and connectNew PEX or copper is run, insulated in the attic, and tied in. The old line is capped.
- Test and patchPressure test the new line, then patch drywall. Paint touch-up may be separate.

Reroute vs. tunneling vs. spot repair
A pipe reroute is usually the cheapest way to avoid breaking floors. Tunneling also saves the floor but costs $4,000 to $12,000 or more because crews dig under the slab by hand. A spot repair costs least for a first leak under tile you can patch.
| Reroute | Tunneling | Spot repair | |
|---|---|---|---|
| Typical cost | $1,500–$5,000 | $4,000–$12,000+ | $1,500–$4,500 + flooring |
| Floor damage | None | None | Small patch |
| Time | 1–2 days | 2–5 days | 1–2 days |
| Post-tension slab | Safe | Safe | Needs cable scan |

PEX vs. copper for a reroute
Most reroutes in Little Elm use PEX. It bends around framing, needs fewer joints, resists hard-water scale and costs less. Copper lasts long too, but costs more and takes longer. In a hot attic, either material should be insulated.
PEX
Flexible, quick to install, handles freeze better, lower cost. Keep it out of direct sunlight.
Copper
Rigid, long track record, higher material and labor cost. Can pinhole in aggressive water.
Questions to ask before you approve a reroute
Ask which fixtures the new line will feed, where it will run, whether attic sections will be insulated, how many wall openings to expect, whether drywall patching and the permit are included, and what warranty covers the new pipe. Clear answers prevent surprise charges.
Route and scope
Will the reroute cover only the leaking line or the whole hot side? Covering nearby lines in the same visit can cost less than a second trip.
Attic protection
North Texas attics pass 130°F in summer and can dip below freezing in winter. PEX in the attic should be insulated and kept off hot decking.
Patching and permit
Ask whether drywall repair, texture and the Town permit are in the price, or extra.
Warranty
Ask how long the plumber warrants labor and the new pipe, and get it in writing.

Slab leak reroute FAQ
Is rerouting better than repairing a slab leak?
Often, yes. A reroute avoids breaking the floor and slab, works on post-tension slabs, and replaces pipe that may leak again. A spot repair can cost less for a first leak in an easy place.
What happens to the old pipe under the slab?
It is capped at both ends and left in place, empty. It does not cause any harm.
Will a reroute leave holes in my walls?
A few small openings at connection points. The plumber patches them. Painting may be a separate small cost.
Does a slab leak reroute need a permit?
Usually yes. Inside Little Elm town limits, a licensed plumber pulls a plumbing permit for a reroute and arranges the inspection. Unincorporated areas follow county or district rules.
Does insurance pay for a reroute?
Some Texas policies pay toward a reroute as an alternative to tearing into the slab, since it can cost less. Ask your adjuster and share the plumber's quote for both options.
