The three ways to fix a slab leak
Spot repair
A small section of floor and concrete is opened at the marked spot, the damaged piece of pipe is replaced, the line is pressure-tested, and the slab is patched. Best for a single leak on a line that’s otherwise in good shape.
Reroute
The leaking line under the slab is capped and abandoned, and a new line, usually PEX, is run through the walls, ceiling or attic to the same fixtures. Best when the line under the slab is old or has leaked before, or when the leak sits under cabinets or expensive flooring.
Repipe
All supply lines in the house are replaced. It costs the most but ends repeat leaks in homes with failing copper or polybutylene pipe. See whole-house repipe cost.
Which repair makes sense in a Greenwood home
| Your situation | Usually the better choice |
|---|---|
| First leak, newer home, line in good shape | Spot repair |
| Leak under kitchen cabinets, hardwood or large-format tile | Reroute, to avoid tearing out finishes |
| Second or third slab leak on the same line | Reroute that line |
| Pinholes showing up in several places in older copper | Repipe, or reroute the worst lines first |
| Hot-side leak with the water heater running all day | Repair soon either way; the heater and gas bill keep climbing |
Greenwood’s hard well water matters here. If one copper line under the slab has pinholed from the inside, the rest of that copper is the same age and has seen the same water, so a reroute often saves a second repair a year later.

- Protect the roomFurniture is moved, the area is sealed off with plastic, and dust control goes up before any cutting starts.
- Open the floor at the markThe flooring is lifted and a small hole, typically a couple of feet across, is cut through the concrete and dug down to the pipe.
- Replace the damaged sectionThe leaking piece is cut out and replaced, and the pipe around it is inspected for wear.
- Pressure-test before closingThe line is tested again with the hole still open, so a second leak nearby isn’t buried under new concrete.
- Backfill and patchThe hole is backfilled, the concrete is patched, and the area is ready for flooring once it cures.
Why pinpointing first keeps the repair small
Without an exact location, a slab repair turns into exploration: a trench across the kitchen, a second hole when the first one misses, flooring replaced in a whole room instead of a few tiles. Detection that marks the leak within inches is what makes a one-opening repair possible, and it’s the part of the job that saves the most money.

Slab leak repair cost
National cost guides put a typical single slab leak repair at about $2,000 to $4,000, with spot repairs often around $1,500 to $3,500 and reroutes anywhere from $600 to $7,500 depending on the length and route of the new line. What moves the price most in Greenwood homes is what sits on top of the leak (tile, hardwood, cabinets), how deep the pipe is, and whether there’s more than one leak.
Detection and repair are quoted separately. See slab leak repair cost for the full breakdown, and get a written quote for your home.
Insurance and paperwork
Many homeowners policies cover the cost of getting to the pipe (breaking and restoring the floor) and the water damage, but not the repair of the pipe itself. Keep the photo report from detection; it shows the cause and location, which is the first thing an adjuster asks for. Read does homeowners insurance cover slab leaks? before you call your insurer.
If the leak ran up your bill, Indiana American Water and many Indiana utilities have a leak adjustment process once the leak is repaired. See water bill leak adjustment in Indiana.
Slab Leak Repair: questions from Greenwood homeowners
Do you repair slab leaks in Greenwood, or only find them?
Both. We pinpoint the leak, then our plumbing partner makes the repair: a spot repair at the mark, a reroute, or a repipe when the pipes keep failing. If you have your own plumber, we give them the mark and report instead.
Is rerouting better than breaking the slab?
Often, yes, when the line under the slab is old, has leaked before, or the leak sits under cabinets or expensive flooring. A spot repair is usually the better value for a first leak on a line in good condition.
Can I wait to fix a slab leak?
It isn’t a good idea. Water under a slab can wash out soil, soak flooring and drywall and grow mold, and a hot-side leak keeps your water heater running. Shut the water off at night if you must wait a few days for the repair.
How long does a slab leak repair take?
A spot repair is usually done in a day, with time afterwards for the concrete patch to cure before flooring goes back down. A reroute can take one to two days depending on the route.
Will insurance pay for slab leak repair in Indiana?
It depends on your policy. Many cover access to the pipe and resulting water damage but not the pipe repair itself. Check your policy and keep the detection report for your claim.
