Frequently Asked Questions About Leak Detection in Great Falls
The cost of leak detection in Great Falls, MT 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.
Yes. Repairs we complete after detection carry a written workmanship warranty. Replacement parts include manufacturer coverage.
Testing well water around Great Falls for hardness, iron and bacteria is the right first step before choosing treatment equipment. 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.
Small repairs typically do not, but reroutes, repipes and main line replacements often do. Requirements vary by city and county. We take care of any permits needed.
Common signs include a sudden spike in your water bill, damp spots on walls or floors, mildew odors, visible mold growth, the sound of running water when no fixtures are in use, or a continuously running water meter even when all water is off.
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.
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 precisely pinpoint.
You can check your meter, test toilets with food coloring in the tank and look for damp spots. Finding leaks under slabs or inside walls requires professional equipment. That is where professional detection saves time and money.
