About American Leak Detection™

Providing Quality Leak Detection & Repair Since 1974

Richard B. Rennick, who understood the need for efficient, reliable leak detection services, founded American Leak Detection. Growing up, Rennick worked for his father’s plumbing company where he had to help locate water leaks in pipes buried under concrete slabs using a 6-pound maul and chisel. Not only was the task tedious and time-consuming, but it left a large mess for the homeowner. It made him realize there had to be a better way to find leaks.

As an adult, Rennick became a police officer and supplemented his income with plumbing jobs on the side. While working in the plumbing industry, he grew even more convinced of the need for a less invasive procedure to locate leaks. Rennick decided to team up with an expert to develop equipment, which could locate concealed leaks. After much trial and error, they were able to develop extremely sensitive electronic tools equipped with minute microprocessors. From these humble beginnings, the electronic leak detection industry was born in 1974.

Since then, American Leak Detection™ has spent a significant amount of money on research and development to ensure that the very best technology is being used to solve your problem.

    "They came in, investigated with smoke, and fixed the problem. For the first time in two months, my house doesn't smell like a restaurant toilet."
    “I had an awful rotten egg smell as soon as I bought our house. After calling two plumbers (who charged me a fee to tell me nothing was wrong), the Gas Company (no gas leak), and the Public Works Department, I finally called American Leak Detection. They came in, investigated with smoke, and fixed the problem. For the first time in two months, my house doesn't smell like a restaurant toilet. Highly recommend them!”
    - Sandi T.
    "I can't say enough good things about their service!"
    “I can't say enough good things about their service! We had a slab leak that flooded the master bedroom and they came as quickly as they could and then rearranged their work schedule so the repair could be made and we could once again have water turned on. The workmen were professional and efficient. I hope I never have to use that kind of service again but if so, they are he best.”
    - Carolyn R.
    "After 30 years in this house, we have had many service people come to do work. No one has ever delivered better than Daniel."
    “Tree roots had cracked my filter pipes and I was losing water badly. I was referred to American Leak Detection and set up an appointment. Daniel came out and did his best to diagnose the problem. He got very strange results and it was hard to determine the exact pipe(s) that were cracked but since I'd had a similar repair done 6 years ago and we could see evidence of the tree root damage from above, I felt confident we knew were the issue was and I contracted for the work. I was pleasantly surprised to see Daniel return to perform the work. I arranged to be home that day so I could see what he found. I supposed I hovered, taking pictures of the process, asking questions as he went along. He never got annoyed and answered every question with a smile. I don't think i ever saw anyone work harder. It was obvious from that start he had a lot of experience and knew what he was doing. Digging out the area had to be done mostly by hand which he did efficiently without complaints. He found multiple pipes cracked which explained the odd results during diagnosis. The job took longer than expected because it was difficult work and he ran out of daylight but on the job until he it wasn't possible anymore that day. Even though he was fully booked for the following day, his company rearranged his schedule so he could return the following afternoon. I returned home early from work and was able to see him complete the job. He even patched the deck with new concrete like an artisan, taking every care to make it as smooth and neat as possible. After 30 years in this house, we have had many service people come to do work. No one has ever delivered better than Daniel. He was competent, diligent, and pleasant. The cost wasn't cheap but it was fair. I don't mind at all paying for quality service.”
