Slab Leak Repairs
Stop hidden leaks before they threaten your foundation.
A slab leak happens when a pipe beneath your home's foundation springs a leak. Because it's hidden underground, it can quietly damage your floors, walls, and structure long before you realize anything is wrong.
With over a century of experience, the plumbers at L.E. Isley & Sons repair slab leaks safely — and we do it with minimal disruption to your home and yard, protecting your foundation and your property.

What We Do
Our slab leak services
Targeted repair
We repair the failed pipe under your slab precisely and cleanly, without unnecessary demolition.
Trenchless pipe lining
A chemical compound coats the inside of the damaged pipe — repairing the leak through two small access points instead of a torn-up floor.
Traditional repair
When access repair is the better option, we do it cleanly and restore the area properly.
Damage prevention
We act fast to minimize structural and property damage and check for related issues nearby.
Know the Signs
Signs you may have a slab leak
Running water with taps off
Hearing water move when everything is shut off is a classic sign water is escaping beneath your home.
Warm spots on the floor
A hot-water-line slab leak transfers heat to the floor above — warm patches underfoot are a red flag.
Unexplained high water bills
A sudden spike in water usage with no change in habits often means water is leaking out of sight.
Cracks or moisture
New cracks in flooring or walls, or unexplained damp spots, can point to a leak working under the slab.

Honest Pricing
What affects the cost
Slab leak repair is flat-rate and quoted up front. The good news: our trenchless method usually keeps cost and disruption down. Factors:
Repair method
Trenchless pipe lining through two small access points costs far less in restoration than jackhammering your floor.
Depth & access
How deep under the slab the failed pipe sits, and how easy it is to reach, affects the repair.
Extent of damage
A single pinhole is simpler than a line with multiple failures.
Restoration
Trenchless lining needs little restoration; a traditional access repair may require more floor or wall work afterward.

FAQ
Slab Leaks — common questions
Usually not. We're proud to offer trenchless pipe lining, which repairs the pipe from the inside using just two small access points — so there's no need to jackhammer your floor or tear up your landscaping.
Serious enough to act on quickly. Because slab leaks are hidden, they can cause significant structural and property damage before you notice. Repairing one early is critical to protecting your foundation.
Most trenchless slab leak repairs are completed in a single visit. Traditional access repairs can take longer depending on how the affected line runs and the restoration involved.
