Slab leak repair & concrete replacement

We dig it up,
fix it, andpour it back.

A leak under the slab is two jobs, not one: the repair, and the concrete that has to go back over it. As a licensed general building contractor we hold both — so you are not left with a finished repair and an unfinished floor.

The part nobody quotes

What happens
to the hole?

Ask any slab leak quote one question: who pours the concrete back, and is it in this number? The answer tells you what you are actually buying.

Repair-only scope

Fixed. And gone.

  • Locate the leak
  • Saw-cut and excavate
  • Repair or reroute the line
  • Pressure test
  • Backfill and compact properly
  • Form and pour the slab back
  • Finish to match the surrounding floor
  • Reinstate flooring, tile or driveway
  • Haul the spoil and clean the site

You are left standing over an open trench
looking for a second contractor.

Repair and pour back on one contract.
The floor goes back the way it was.

How a slab repair runs

Find it. Open it.
Fix it. Close it.

No mystery and no “we will see when we are in there.” Here is exactly what happens between your call and your floor looking like a floor again.

Stage 01

Find it

Leak location before any demolition, so we open the smallest area that does the job instead of guessing across your slab.

Stage 02

Open it

Saw-cut, excavate and shore. Floors covered and the work area sealed. Photographed at every stage for you and, if it applies, your insurer.

Stage 03

Fix it

Repair or reroute, with new fittings to code. Pressure tested and inspected before anything gets buried — because burying a bad repair is the expensive mistake.

Stage 04

Close it

Backfill, compact, form, pour and finish. Flooring or hardscape reinstated. The surface goes back so you would never know we were there.

What it costs

Two numbers,
one contract

Most slab leak quotes cover the repair only. Ours covers the repair and the concrete, because you were never going to be finished without both.

[[$XX–$XX]]

[[His real range for a
single-point slab repair
including pour back.]]

  • Depth and accessA leak under an open floor is not the same job as one under a kitchen island or a load-bearing wall.
  • Repair or rerouteSometimes a spot repair is right. Sometimes rerouting the line overhead is cheaper and lasts longer. We tell you which.
  • Surface aboveBare slab, tile, hardwood and a stamped driveway are four different reinstatement jobs.
  • Length of runHow much line has to come out drives both the excavation and the concrete going back.
  • Damage already doneIf the leak has been running a while, there may be subfloor or drywall work behind it. Priced and approved before we touch it.

Backed for five years

If our workmanship fails,
we come back and fix it.

Five years of workmanship warranty on the work and on the finish that closes it. Same company, same phone number, same crew. Terms are written into your contract before you sign anything, so the promise is a document rather than a sales line.

Questions we actually get

Before you call anyone

How do I know I have a slab leak?

The usual signs are a warm spot on the floor, a water bill that jumped for no reason, the sound of running water with everything off, or the meter turning when nothing is on. Any one of those is worth a call. Left running, a slab leak damages the house far beyond the pipe.

Do you repair the line or reroute it?

It depends on the age of the system and how many failures there have been. One failure in an otherwise sound system is usually a spot repair. Repeated failures mean the material is at end of life, and rerouting or repiping is the cheaper answer over any reasonable timeline. You get our honest read, in writing.

Will my floor match afterwards?

The concrete will be structurally correct and finished flat. Matching a finished floor surface — tile from a discontinued run, stained concrete, patterned hardwood — depends on the material. We will tell you honestly at the walk-through what will match and what will be visible.

Is this covered by homeowner’s insurance?

Policies vary widely, and we are contractors rather than adjusters, so we will not tell you what yours covers. What we will do is photograph every stage of the work so you have proper documentation to submit.

Are you licensed and bonded?

Yes. CSLB license #1079728, Class B, General Building Contractor, active through August 2027. We carry a $25 through Atlantic Specialty and $2 through State Farm. Verify the licence yourself at cslb.ca.gov before you let anyone into your house — we would rather you did.

What deposit do you take?

California caps a residential down payment at $1,000 or 10% of the contract price, whichever is less. Payment after that follows a written progress schedule tied to completed stages, so you always know what you are paying for. If any contractor asks for a large payment up front, that is your signal to walk.
