Hidden water, gas and slab leak detection in Sebastopol, with crews from our Santa Rosa and Petaluma offices.
Leak detection in Sebastopol is about tracing a pipe you cannot see, such as a buried service line, a line running out to a well or a pipe under a slab. If you are paying for water that never reaches a faucet, a hidden leak is the first thing to rule out.
We serve Sebastopol from our Santa Rosa and Petaluma offices. Our technician trained at the FAST factory in Southern Germany, and we use the FAST Aqua M300 to listen for leaks, detect tracer gas and locate pipes. That helps us find a leak along a long buried line without trenching the whole run.
We also test for gas leaks and look for leaks in slabs with radiant heating. Once we locate the problem, we explain what we found and what repair makes sense. If you smell gas, leave the home and call your gas utility or 911 first, then call us. More on our Leak Detection Services page.
Good leak detection depends on the tool and the person using it. Our technician trained in person on the FAST Aqua M300.
We use acoustic listening equipment and pipe location to trace the line and hear where water is escaping. Tracer gas can confirm the spot. This lets us name a specific point along the run, so any digging stays focused there instead of following the entire line.
It depends on what we are looking for and how the pipes are laid out, so we cannot quote a figure without hearing about your situation. Call us and describe the symptoms, and we will explain what comes next. Financing is available if a repair turns out to be larger.
Get everyone out of the home right away and avoid sparks or flames. Call your gas utility and 911 from outside. Once the situation is safe, we can locate the leak in the piping and repair it before service is restored, which is work we handle.
Plumbing and sometimes radiant heating pipes run beneath a concrete slab. We use acoustic listening equipment, thermal imaging and tracer gas to locate the leak from above, before anything is cut. Warm floor spots and running-water sounds are common clues.
Yes. We offer plumbing repair along with leak detection, so we can repair water, gas and slab leaks after we locate them. We will explain the options first. Seniors and veterans save $50 on any repair, and financing is available for larger work.
