Frequently Asked Questions About Leak Detection in Shoreline
Leak detection in Shoreline usually costs $150 to $450 for a typical home, depending on the size of the system and the number of areas tested. Pool leak detection runs about $250 to $500. We tell you the price before we start.
Most standard leak detection services can be completed within 1 to 3 hours. More complex cases, such as multiple leaks or hard-to-access areas like under a slab, might take longer to accurately pinpoint.
Turn off all water in the house and watch the meter. If the leak indicator or dial moves, water is escaping somewhere. A sudden jump in your water bill is another strong sign.
We use a range of professional tools including acoustic listening devices, thermal imaging cameras, specialized moisture meters, pressure testing equipment and tracer gas detectors for precise and non-invasive leak identification.
Older galvanized steel pipes are prone to corrosion, and some older polybutylene pipes are known for premature failure. However, even modern materials like copper or PEX can leak due to improper installation, high water pressure or foundation shifts.
Many homeowners policies cover the cost of finding and accessing a sudden leak, though coverage varies. We provide a written report with photos to back up your claim. Check with your insurer about your specific policy.
Small repairs typically do not, but reroutes, repipes and main line replacements often do. Requirements vary by city and county. We handle any permits needed.
We use acoustic ground microphones, thermal imaging cameras from brands like FLIR, line tracers, moisture meters and pressure test gauges. Each tool helps confirm a different type of leak. Using several together gives reliable results.
