Leak Detection & Slab Leak Repair in Chandler, AZ
Most Chandler homes are built on slab foundations, which means a leaking supply line usually isn't visible - it's under a few inches of concrete. A slab leak in Chandler often traces back to polybutylene pipe installed during the city's big building boom of the 1980s and 90s, which degrades from the inside as chlorine in the municipal water breaks down the plastic over decades. We use electronic leak detection to find the leak's location before any concrete is opened, instead of guessing.
Signs You Might Have a Slab Leak
You don't need to see water to have a slab leak. The signals most Chandler homeowners notice first are a warm spot on an otherwise cool floor, a hissing sound near the slab when no fixtures are running, an unexplained jump in the water bill, or a section of flooring that stays damp or develops a musty smell for no obvious reason. Any one of these is worth a professional leak detection call before the damage spreads.
How We Find a Leak Without Opening the Slab
Electronic leak detection listens for the acoustic signature of water escaping under pressure and cross-references it with the home's actual plumbing layout, which lets us narrow the leak down to a specific location before any concrete is touched. We combine that with pressure testing to isolate which line - hot or cold, and which run - is actually losing water, since guessing wrong means opening the wrong section of floor.
Once we've confirmed the location, there are generally two paths: a targeted slab penetration to access and repair that exact section of pipe, or a reroute that runs a new line through the attic or walls instead of back through the slab. Which one makes sense depends on the pipe's age, material, and how many other sections are likely to fail next - something we'll walk through with you before you decide, especially on a home old enough that the whole polybutylene run may be near the end of its life.
Polybutylene Pipe and Chandler's Building Boom
Chandler's population grew dramatically during the 1980s and 90s as tech employers like Intel expanded in the area, and polybutylene resin pipe was standard supply-line material industry-wide during much of that window. It was inexpensive and easy to install, but it wasn't built to last indefinitely - chlorine in municipal water slowly breaks the material down from the inside, and pipes installed during that era are now well past the point where failure becomes more likely rather than less. When one section fails, it's often a sign the rest of the run isn't far behind, which is part of why we talk homeowners through the reroute option rather than only patching the one leak we found.
What It Typically Involves
| Situation | Typical Approach | Usual Timeframe |
|---|---|---|
| Warm spot or hissing sound, no visible water | Electronic leak detection, pressure test | Same visit for diagnosis |
| Confirmed single-point slab leak | Targeted slab access and repair | 1–2 days depending on access |
| Older polybutylene home, recurring leaks | Reroute discussion (attic/wall bypass) | Scheduled, multi-day project |
| Unexplained water bill increase | Full-system pressure test | Same visit |
Questions Chandler Homeowners Ask
Electronic leak detection equipment listens for the sound signature of escaping water and, combined with pressure testing, narrows the leak to a specific section - usually a few feet, not the whole slab - before any concrete is opened.
It isn't illegal to have in your home, but it's no longer installed in new construction because of its known failure pattern over time. If your Chandler home was built in the 1980s or 90s, it's worth having the supply lines checked.
Coverage varies by policy and carrier - some cover the cost to access and repair the leak but not the underlying pipe replacement. Check your specific policy, since we can't speak for what your insurer covers.
It depends on the pipe's age and material. If it's polybutylene from the same era as the leak we just found, a full reroute often costs less in the long run than repairing recurring leaks one at a time. We'll lay out both options with real numbers before you decide.

Occasionally what looks like a slab leak turns out to be condensation or a slow drain leak instead of a supply-line failure. If you're not sure which you're dealing with, our drain cleaning page covers the more common drain-side causes of unexplained moisture.
