We use current water leak detection technologies from leading manufacturers and choose the right method for the property, pipe, and conditions in front of us.
Every method is non-invasive and non-destructive to your home, business, landscape, or established surfaces. Our job is to find the problem accurately, then give the right repair team a reliable place to start.
Locate hidden leaks
Underground water lines, slab leaks, and difficult plumbing leaks can be located without opening up the property to search by guesswork.
Use the right signal
Acoustic, electronic, and hydrogen tracer-gas technologies help us confirm a leak location when one method alone is not enough.
See temperature-related clues
Infrared technology can assist with slab leaks and other interior leaks by revealing patterns that are otherwise hard to see.

Find the source before you decide what to fix.
When water loss is somewhere beneath a property, the first question is not always “How much should we replace?” It is “Where is the problem, and what can it tell us?”
A precise find gives you and your repair contractor better information before a yard, driveway, floor, or wall is opened. Our role is focused: investigate the evidence, locate the source, and give the next step a clear starting point.
Locate before replacing
A precise find can turn a whole-line replacement into a targeted repair and reveal whether the problem is in an accessible location.
Keep the evidence
A small piece of removed pipe can help identify the material and give you useful context if another problem develops in the future.
Repair with a clearer plan
You and your plumber can work from a marked location and real information instead of opening up a property to search by guesswork.
Simply Leak Detection is a leak-locating specialist, not a plumbing repair contractor. We provide the information your chosen repair professional needs to move forward with confidence.
