Three options, and the pipe decides
There is no single correct method for a slab leak, and being offered only one is a reason to ask why.
Spot repair opens the floor at the located point, replaces the failed section and patches the slab. It is the least disruptive and the right answer for a first failure in a sound line.
Rerouting abandons the buried run and installs new pipe where it can be reached, through walls or overhead. More work now, but it takes that section out of the foundation permanently.
Repiping replaces the supply system where multiple runs are failing.
What separates them is not preference. It is whether the pipe under your slab has one problem or a general condition.
The second leak changes the arithmetic
This is the moment the sensible answer usually changes.
One leak can have a specific cause: a point of abrasion, a bad joint, damage from construction. Spot repair it and it stays repaired.
A second leak on the same run says something different. The pipe is failing along its length, and every future failure carries the same cost of cutting concrete and reinstating a floor. Two or three of those add up to more than a reroute, and the reroute ends the problem rather than deferring it.
So at the second leak, the question is worth reopening even if the first repair went perfectly.
Does this sound familiar?
Problems this service solves
- A confirmed leak in a line beneath the slab
- A second slab leak on the same run
- Copper under slab that has begun failing generally
- Water damaging flooring from below
- Foundation movement caused by saturated soil
Signs you need slab leak repair
If more than one of these is true, the problem is usually past the point a plunger or a store-bought cleaner will fix.
- Detection has located a leak under the slab
- This is not the first leak in the same house
- Flooring is lifting or discoloured in a patch
- The slab is audibly or visibly wet
What to expect
How the visit works
Confirm the location
Repair follows detection. Cutting concrete on an approximate position is how one opening becomes three.
Weigh the three options
Spot repair, reroute above the slab, or repipe. Which is right depends on the age and condition of the line, not on which is quickest.
Carry out the repair
A spot repair opens the floor at the marked point, replaces the failed section, and the slab is patched. A reroute abandons the buried run and takes new pipe overhead or through walls.
Test under pressure
The system is repressurised and the meter watched before anything is closed up, so a second leak on the same run is found now rather than later.
What's included
What you get on every job, whoever we send.
- A repair method chosen against the pipe's condition
- Rerouting offered where repeated failure makes it the cheaper answer
- Concrete opened once, at a located point
- Pressure tested before the floor is closed
Questions
Slab Leak Repair questions
Should I repair the leak or reroute the pipe?
It comes down to whether this is the first failure or part of a pattern. A single leak in an otherwise sound line, particularly from a specific cause like abrasion at one point, is worth a spot repair. A second leak on the same run means the pipe is failing generally, and every future leak carries the same concrete-cutting cost. At that point rerouting the line above the slab, where it can be reached, is usually cheaper over any reasonable timeframe.
What does rerouting actually involve?
The buried section is abandoned in place and a new run is installed where it can be accessed, typically through walls, an attic or a ceiling void. It sounds more disruptive than cutting one hole in a floor, and for a single leak it often is. Its advantage is permanence: the new pipe is reachable, so any future problem is an ordinary repair rather than another excavation through the foundation.
Does the concrete get put back properly?
Yes, and it should be part of the quote rather than an afterthought. The opening is cut cleanly, the repair is made and tested, and the slab is filled and finished back to level. What is not included is replacing the flooring above it, which is a separate trade, so it is worth clarifying who is doing what before work starts rather than after the floor is open.
