Slab Leak Detection in Fort Collins

Non-Invasive Foundation Leak Detection for Fort Collins Homeowners

Hot and cold water lines run beneath the concrete slab in most Fort Collins homes built on a slab foundation. When one of those lines develops a leak, the source is hidden from view and the damage accumulates quietly. American Leak Detection locates those leaks precisely before any concrete is touched, applying the Leak Detection Without Destruction™ principle that defines our entire practice.

We’re part of the recognized world leader in non-invasive location of concealed leaks, backed by over 40 years of industry experience. If your water meter is moving when no water is being used, that’s a primary signal that something may be leaking beneath your slab. Our job is to find exactly where.

Call American Leak Detection at (866) 701-5306 to schedule slab leak detection in Fort Collins. We can confirm whether a leak is present and pinpoint its location before any work is done to your home.

Why Fort Collins Homeowners Choose American Leak Detection

As the original Leak Detection Specialists™, our methodology reflects that identity. Our proprietary techniques for locating slab leaks were developed over decades of research and field work. We don’t combine detection with broad plumbing services under one umbrella. Finding hidden leaks without causing damage is what we do.

Our technicians arrive on time, complete the job within the given time frame, and leave your property clean. Pricing follows our Know Before You Go approach: you understand the cost before work begins, with no surprises on the invoice.

How We Locate a Slab Leak

Imprecise detection methods mean breaking up large sections of concrete to search for a leak that could be anywhere. Our four-step process eliminates that guesswork.

  • Tracking the plumbing lines: We map the layout of your under-slab potable water plumbing to establish the full picture of what’s running beneath your foundation.
  • Pressure testing the lines: We test the hot line, cold line, and the service line running from the meter to the house independently, isolating which line is losing pressure.
  • Determining the location of the water loss: Using acoustic leak detection and advanced non-invasive equipment, we narrow the leak to a specific point along the affected line.
  • Marking the location: We mark the exact spot on the slab surface so your plumber or repair contractor knows precisely where to work.

Pinpointing the leak before excavation begins can save thousands of dollars compared to search and destroy or hit and miss approaches. The slab stays intact everywhere except where the repair actually needs to happen.

Why Slab Leaks Are a Real Risk in Fort Collins

Fort Collins sits on expansive bentonite clay soil. Bentonite swells when it absorbs moisture and contracts as it dries, and that cyclical movement shifts the ground around buried supply lines. Over years of wet and dry seasons, the stress on under-slab plumbing builds. The area also experiences dramatic temperature swings that can push readings well below freezing in a matter of hours, and repeated freeze-thaw cycles create mechanical stress that can produce pinhole leaks in buried pipes.

Fort Collins water is mineral-rich, too. Calcium and magnesium deposits build up inside buried supply lines over time, thinning pipe walls and increasing vulnerability where soil movement applies lateral force. Newer subdivisions in southeast and northeast Fort Collins built on clay-heavy soils can face elevated risk as those soils shift with the seasons. Foundation leak detection in Fort Collins isn’t a precaution for unusual circumstances. For many homes here, it can become necessary over time.

American Leak Detection serves Fort Collins and the surrounding Larimer County area. When the signs point to a slab leak, our non-invasive detection process helps protect your floors, walls, and foundation throughout. No unnecessary damage. No guesswork.

    "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!”

    "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.”
