How serious is a slab leak?

Serious enough to act on quickly. Water under the foundation erodes the soil that supports it, and that is how floors settle and crack. It also feeds mold you cannot see.

Why are slab leaks so common in Mesa?

A few local facts stack up against you. Homes here sit slab-on-grade, so supply lines run under the concrete. Our water is very hard on copper, and the desert soil expands and shifts with moisture.

Will you have to break my floor?

Not always. We can often reroute the line overhead and skip the slab, the smart move for old copper that will keep failing. When we do open the slab, tight detection keeps the hole small.

How much does slab leak repair cost in Mesa?

It depends on where the leak sits and whether a spot repair or a reroute makes more sense. Pinpointing first keeps the cost down, because nobody is breaking concrete to go exploring. You get the full price before we start.

Does homeowners insurance cover slab leaks?

Many policies cover the water damage and the cost of finding the leak, but not the pipe repair itself. Check your policy. We document what we find so you have backup for a claim.

A leak under the concrete will not wait

Valley homes are built slab-on-grade, with no basement between your floor and the pipes. Copper lines under the slab take a beating here. Very hard water scours them from the inside while shifting soil stresses them from the outside.

A slab leak runs day and night, soaking the ground under your foundation. The sooner it is pinpointed, the smaller the repair and the bill.

Signs of a slab leak

Slab leaks hide well. These are the tells Mesa homeowners notice first.

A warm spot on the tile or carpet
The sound of running water with every fixture off
A water bill that keeps climbing month after month
Damp baseboards or flooring that lifts or buckles
The water meter spinning while nothing is on
Hairline cracks spreading across floors or walls
Low pressure that showed up along with any of these

How we repair a slab leak

Confirm it is under the slab

Meter tests and pressure checks rule out the easy answers first, like a running toilet or an irrigation leak.

Pinpoint the line

We trace the leak to a tight spot before anyone touches concrete. Accuracy here is what keeps the hole small.

Agree on the fix

You see what we found and get a firm price before work starts. Nothing is opened without your OK.

Repair or reroute

Some leaks get repaired at the spot. Others are better rerouted overhead through the attic, so the failed line under the slab is retired for good.

Test and close up

We pressure-test the repair and watch the meter sit still. Only then does the access point get closed up cleanly.

Why Mesa homeowners hand us their slab leaks

Detection and repair, one crew: Plenty of leak-detection outfits find the leak and hand you a report. We find it and fix it in the same visit, which is faster and cheaper than starting over with a second company.
We respect your foundation: Breaking concrete is a last resort, and when it happens the hole is as small as the repair allows. If a reroute spares your slab entirely, we will tell you so.
