One pinholed copper line under a slab is often a local repair. Recurring leaks in aging Type M copper usually deserve a reroute or repipe conversation. The right choice depends on leak count, pipe age, access, and how long you plan to keep the house.
After detection, homeowners ask a bigger question than tunnel vs jackhammer: should we keep fixing under the slab, lift the lines above it, or repipe more of the house? This framework keeps that talk grounded. Pair it with tunneling vs break-out, PEX vs copper, and repiping.
Local repair under the slab
Best when:
- Detection finds a single clear failure
- Nearby copper still looks sound
- Access (tunnel or break-out) is practical
- The home has not had a string of slab leaks already
Local repair is the smallest intervention. It does not rejuvenate the rest of an aging buried system.
Reroute above the slab
A reroute abandons a problem under-slab segment and feeds fixtures through walls, attic, or other accessible paths — often with PEX. Best when:
- The failed zone is hard to reach repeatedly
- You want future repairs to happen in open air, not under concrete
- Several leaks cluster on one branch
Reroutes change how the house is plumbed; the written scope should show the new path clearly.
Fuller repipe
When copper throughout the slab has reached the end of its useful life — multiple leaks across rooms, widespread Type M, green copper stains at many sites — a larger repipe may be the straight story. That is a bigger project with bigger planning, and financing available if you want to spread payments. We still start with detection so you are not repiping on a guess.
Quick decision grid
- First leak, clear location, sound nearby pipe → local repair
- Second or third leak on the same branch → weigh reroute
- House-wide copper failures → weigh repipe
- Finished floors over a single leak → prefer tunneling when access allows (see the Dallas tunnel case study)

Frequently asked questions
Will you push a repipe on every slab leak?
No. Many leaks are honest local repairs. We recommend larger work when the pattern supports it.
Is a reroute the same as a whole-house repipe?
No. A reroute can be limited to the failed branch. A fuller repipe replaces more of the supply system.
Can I repair now and repipe later?
Sometimes yes. A solid local repair can buy time while you plan a larger project — as long as you understand remaining buried copper may still fail later.
Do you haul away old water heaters during related work?
On water heater replacements, yes, we haul away the old unit. Ask us to coordinate if both jobs are on the calendar.
