Spot repair or reroute: the short version
| Spot repair | Reroute | |
|---|---|---|
| What happens | Floor and concrete are opened at the mark, the bad section is replaced, the slab is patched | The line under the slab is capped and a new line runs through walls, ceiling, attic or crawl space |
| Best when | First leak, pipe in good shape, leak in an easy spot | Older pipe, repeat leaks, or the leak sits under cabinets or finished flooring |
| Disruption | One opening in the floor | Small openings in walls and ceilings along the new route |
| Future leaks on that line | Possible, if the rest of the pipe is worn | That line is no longer under the slab |
Why rerouting often fits older Franklin homes
Many Franklin houses are partly on a slab and partly over a basement or crawl space, usually because of an addition. That helps with a reroute: instead of running the new line through finished walls and ceilings, it can often run through the crawl space or basement to the edge of the slab and come up inside one wall.
Pipe age matters too. If the leaking line is old copper or galvanized steel, the rest of that run under the slab is the same age. Fixing one spot and closing the floor can mean opening it again in a year or two. A reroute ends that risk for the line.

- Pinpoint the leakStart with slab leak detection in Franklin so the floor is opened once, in the right place.
- Protect the roomFurniture out, plastic sheeting up and dust control in place before cutting.
- Cut a small access holeFlooring is lifted and a small square of concrete is cut out and dug down to the pipe.
- Replace the section and testThe leaking piece is replaced and the line is pressure-tested again before anything is closed.
- Patch and restoreThe hole is backfilled and the concrete is patched, ready for flooring once it cures.
When a repipe is the better answer
- You’ve had leaks in more than one place in the last few years.
- The house still has a lot of galvanized steel, with low pressure or rusty water. See galvanized pipe replacement.
- There is gray polybutylene pipe anywhere in the house. See polybutylene pipe replacement.
- You’re planning a remodel that opens walls anyway.

What slab leak repair costs
National cost guides put a typical single slab leak repair at about $2,000 to $4,000. Spot repairs are often $1,500 to $3,500, and reroutes range from about $600 to $7,500 depending on how far the new line has to run. In Franklin homes, what sits on top of the leak (tile, original hardwood, cabinets) and whether there’s crawl space access for a reroute make the biggest difference.

Insurance and your water bill
Homeowners policies often pay to break out and restore the floor and for the water damage, but not to fix the pipe. Keep the detection report: it shows where the leak was and what caused it. See does homeowners insurance cover slab leaks?.
If the leak ran up your bill, ask your utility about a leak adjustment once the repair is done. See water bill leak adjustment in Indiana.
Slab Leak Repair: questions from Franklin homeowners
Do you fix slab leaks in Franklin, or only find them?
Both. We pinpoint the leak, then our plumbing partner repairs it with a spot repair, a reroute or a repipe. If you have your own plumber, we hand them the marked spot and report.
Can the new line run through my crawl space instead of the walls?
Often, yes. Many Franklin homes have a crawl space or basement beside a slab addition, which gives an easier route for the new line than finished walls and ceilings.
Is it worth rerouting after just one leak?
It can be, if the pipe is old copper or galvanized or the leak is under cabinets or expensive flooring. For a first leak on a line in good condition, a spot repair is usually the better value.
How soon should a slab leak be repaired?
As soon as you can. Water under a slab soaks flooring, can wash out soil and grow mold, and a hot-side leak keeps the water heater running. Close the main shutoff overnight if the repair is a few days away.
