Services
Infrared Inspection
Our infrared inspection service uses thermal imaging technology to detect hidden water leaks behind walls, under slabs, and beneath landscaping. This non-invasive method identifies temperature variations caused by moisture, allowing precise leak location without destructive testing. Commercial and residential clients benefit from rapid diagnosis of roof, plumbing, and structural leaks while maintaining property integrity.
Pipeline Leak Detection
Pipeline leak detection combines acoustic sensors, in-line cameras, and ground probes to identify leaks in municipal water mains, fire lines, and underground utilities. Our specialists use blueprint analysis and frequency-sensitive equipment to locate pinhole leaks and structural weaknesses in pressurized systems. This service prevents water loss and infrastructure damage for industrial, commercial, and residential applications.
Plumbing Repair
Emergency plumbing repair services address water, gas, and sewer line failures using ultrasonic listening devices and pressure testing. Our technicians perform non-destructive pipe location and repair for slab leaks, burst pipes, and clogged drains. Residential and commercial clients receive 24/7 response for urgent leak mitigation and system restoration.
Slab Leak Detection
Slab leak detection employs ground-penetrating radar and thermal imaging to identify water leaks beneath concrete foundations. This specialized service prevents structural damage by locating hidden leaks in residential and commercial buildings. Our technicians use acoustic monitoring to trace leaks through foundation slabs without requiring demolition.
Underground Leak Detection
Underground leak detection utilizes advanced ground microphones and tracer gas to pinpoint leaks in buried water, gas, and sewer lines. This method identifies leaks in utility lines, irrigation systems, and storage tanks without excavation. Clients benefit from reduced repair costs and minimized landscape disruption through our precision leak location technology.

I had a leak, and requested the leak detection services; Was given a window of 1 to 5 pm. Got a call at 545 PM, and was told they do not offer the service. Thanks for wasting my time!

Tough problem - A significant leak with no visible surface moisture and over 250 feet of potential sources. Kevin was able to find it quickly, and then verify using other methods it before we committed to taking up a bit of asphalt. His 'X marks the probable spot' missed by maybe 4 inches. My wife and I fixed our 1000 gallon/day leak ourselves before dinner. Kevin's bill was higher than I'd have liked, due to the complex nature of the problem and the need to use helium to confirm the probable location of the leak, but the fix cost us a $20 trip to Lowes, some beer and take out food! Kevin was very friendly and easy to communicate with. We were happy to pay for the right tools in the hand of a seasoned pro. Highly recommend.

Excellent leak detection service. I had Leak Masters come out to our development to locate a leak on our main line from the meter to the home and they did this with great accuracy. I would hire them again to locate leaks on our property, very pleased with their help.

I hired Leak Masters to come out and locate a leak that we had on our property. Kevin with Leak Masters was very professional, he was on time and was very clean. He explained all that had to be done to locate our leak. He located the leak on our property and marked out the exact location. He was able to guide us on the next step for a repair of the broken water line. His suggestions were so precise that I followed his lead and was able to save hundreds of dollars with his suggestions on how to fix the leaking pipe. I was very happy that I had hired Leak Masters to locate our leak. I would use them again and give them the highest rating for being on time efficient and very professional.
