Advantages of Targeted Leak Isolation

  • Prevents Structural Destruction: Pinpointing concealed water line leaks early stops subfloor rot, drywall collapse, and foundation erosion before major rebuilding is required.
  • Reduces Spiking Water Bills: Locating continuous underground or in-wall pipe leaks stops hundreds of gallons of wasted water from inflating your monthly utility costs.
  • Prevents Mold & Mildew Growth: Finding minor moisture seepage prevents toxic black mold and mildew colonies from establishing behind wall cavities and floor joists.
  • Preserves Property Value: Timely detection and code-compliant pipe repair safeguard your home’s structural integrity, finishes, and overall resale value.
LEAK ISSUES HANDLED

Diagnosing & Isolating Hidden Pipe Leaks

  • In-Wall Supply Line Leaks: Corroded copper or failing PEX supply lines inside interior walls produce wet drywall, peeling paint, and bubbling wallpaper.
  • Slab & Underground Pipe Leaks: Subterranean supply line breaks underneath concrete slab foundations cause warm floor spots, foundation cracks, and damp basements.
  • Ceiling & Upper-Floor Leaks: Second-story bathroom pipe or drain stack leaks cause discolored water rings, sagging plaster, and ceiling drips.
  • Unexplained Spikes in Water Bills: Sudden, dramatic increases in water utility bills indicate continuous hidden water line loss even when no surface water is visible.
  • Subfloor & Foundation Dampness: Water pooling along basement floor borders or crawl spaces signals concealed main water line or perimeter drainage failures.
  • Continuous Running Water Sounds: Hearing running water behind fixtures or walls when no faucets are open indicates an active pressurized supply leak.
PROFESSIONAL DIAGNOSTIC CAPABILITIES

Full Leak Tracing on Every Service Call

Our technicians use specialized testing gauges and inspection tools to isolate active leaks cleanly.

  • Acoustic & Physical Pressure Isolation: Targeted pressure testing isolates pressure drops across distinct cold, hot, and irrigation supply lines.
  • Moisture Trace Evaluation: Systematic moisture metering maps moisture boundaries across walls, hardwood flooring, and concrete subfloors.
  • Optical Wall & Ceiling Inspection: Non-invasive camera scope probes evaluate pipe condition behind enclosed cavities with minimal surface disruption.
  • Foundation & Slab Line Mapping: Tracing sub-slab line routing to isolate compromised pipe segments before executing repairs.

We found an unexpected water leak, called Stang Plumbing and they responded within the hour on the same day. Jeff arrived promptly and was very knowledgeable and helpful. He got right to work and helped us start digging into the problem. The problem ended up being more complex than anticipated and we got extra help from John, who was also fantastic. They recommended a restoration company for us to work with and made sure we understood all elements of the issue. Very happy with the service and would 100% recommend or hire them again.

This was our first time using Stang Plumbing for a problem in our upstairs shower - replacing an old broken diverter valve in an extremely tight space. To say we are happy with the results would be an understatement. Jason Morris, the plumber Stang sent over was not only personable but focused, professional and efficient. This is a guy who knows exactly what he's doing! To make things even better, the cost was by far the lowest from over a dozen calls I made to other services. We are "5-star" happy with the results! A huge shout out to the crew at Stang.

Second time using Stang Plumbing & Heating and very pleased with their service! Jaison was very dutiful and polite. He took the time to explain things and was very knowledgeable and nice. His experience definitely shows. He got both jobs done in no time. Also, the front desk lady's reception was very pleasant and welcoming. This is a company run by and comprised of good, honest working people who value professionalism and transparency. (A rare find these days.) Happy to call on Stang Plumbing & Heating again and again =)

During a recent major snowstorm, my water heater failed due to a blocked roof vent. I discussed my problem with Dawn of Stang Plumbing and John and Rob arrived the very next day to analyze / troubleshoot the problem. As a result, they formulated a plan to identify / remediate the problem. I’ve used their plumbing services many times in the past and I’ve always been very satisfied. They are all extremely friendly and very competent professionals. I would highly recommend to my family and friends!

This is the fourth time over the years, that I have used Stang Plumbing. One time for a leak in the basement, once for a new kitchen sink and faucet install, with me supplying the faucet and the sink, another time for repair of a leak under the kitchen sink. And this time for a garbage disposal install, with Stang plumbing supplying the disposal. Each time they were responsive with an upfront price quote. Each time they arrive the next day as promised. All their personnel are polite and professional. Each time the job was done right and the technician left the job site neat and clean when they finished. I think their prices are resonable and competitive, and I do like that they have senior citizen's discount. Stang Plumbing will always be my first choice, when it comes to my needs for any plumbing work.

Accuracy Distinguishes between pressurized supply leaks, drain seeps, and groundwater Frequently mistakes water traveling along studs for the actual leak source

Common indicators include unexplained spikes in water bills, damp spots on drywall or ceilings, discolored flooring, warm areas on concrete floors, the sound of running water when fixtures are off, and musty odors.

Yes. Using static pressure isolation and moisture tracing, we locate the approximate path and breach point of sub-slab pipes before any localized opening or pipe rerouting takes place.

Even a small pinhole supply leak operating under standard municipal water pressure can waste over 1,000 gallons of water per day, resulting in dramatic, unexpected increases on your monthly water bill.

If an isolated copper pipe section beneath a slab has a localized failure, a spot repair may be sufficient. If the pipe exhibits widespread corrosion, installing an overhead bypass reroute through walls or ceilings is often more cost-effective.
