Slab Leak Detection & Repair
A slab leak — a water line break under your concrete foundation — can cause massive structural damage if left unchecked. H3 Plumbing & Drains uses electronic detection to pinpoint the exact leak location, then repairs it with minimal disruption to your home.
About This Service
Slab leaks occur when water supply or drain lines under your home's concrete foundation develop a break or leak. Because these pipes are hidden below several inches of concrete, the leak can go unnoticed for months while water erodes the foundation, promotes mold growth, and drives up your water bill. We use electronic acoustic equipment to locate the leak precisely — so we only break the concrete where we absolutely need to.

Frequently Asked Questions
What are the signs of a slab leak?
Common signs include unexpectedly high water bills, the sound of running water when all fixtures are off, hot spots on your floor, cracks appearing in walls or flooring, or moisture and mold near the base of walls. If you notice any of these, call us promptly — the longer a slab leak runs, the more damage it causes.
Do you have to break my entire floor to fix a slab leak?
No. We use electronic detection equipment to pinpoint the exact location of the leak before any concrete is touched. In many cases, we only open a small targeted area. In some situations, rerouting the pipe through walls or the attic is the best option — we'll discuss all approaches with you upfront.
Will my homeowner's insurance cover slab leak repair?
Many policies cover the cost of accessing the leak (breaking the concrete) but not the pipe repair itself. We can provide detailed documentation to support your insurance claim.
