That keeps excavation to a small, focused hole.

Frequently Asked Questions About Leak Detection in Bismarck
The cost of leak detection in Bismarck, ND can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or hard-to-reach pipe leaks may be at the higher end. We provide a written estimate after our initial assessment.
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 advanced tools including acoustic listening devices, thermal imaging cameras, specialized moisture meters, pressure testing equipment and tracer gas detectors for accurate and non-invasive leak identification.
Many rural homes get water from private wells or rural water systems, and iron and sulfur odors are common complaints. Hard or aggressive water can cause pinhole corrosion in copper pipes over time. Slab foundations on shifting soils also put stress on pipes underneath the house, and high water pressure in some areas adds more strain.
While you can check for obvious leaks, hidden leaks often require professional equipment like acoustic sensors, thermal cameras or tracer gas to locate accurately. A professional plumber will pinpoint the source without unnecessary damage to your home, saving you time and money.
Small repairs usually do not, but reroutes, repipes and main line replacements often do. Requirements vary by city and county. We handle any permits needed.
Yes. Repairs we complete after detection carry a written workmanship warranty. Replacement parts include manufacturer coverage.
Leak detection itself usually does not require a permit. However, if the leak requires significant repairs, such as replacing a section of a main water line, gas line or extensive slab repair, then a plumbing permit from Bismarck may be necessary. We will advise you on any permit requirements.
