Welcome to American Leak Detection, the "Original Leak Specialists." Since 1974, we have detected nearly 5 million leaks, saving homes and business owners billions of dollars in costly repairs.

American Leak Detection offers a non-invasive way to test and locate leaks on the potable hot and cold water systems through out the house. Our detections include a thoroughly check of the water system, identification of the origin of the leak, multiple estimates for the repair and a solid guarantee with our services.

Accurate leak detection requires a combination of two things:

  • Specially trained experts: Our technicians have completed the industry's most extensive training program and are highly skilled to accurately locate the most difficult leaks, without destruction.
  • Quality equipment: American Leak Detection has taken its job a step further by implementing its own proprietary methods and technology to ensure the most non-invasive leak detection possible.

  • Non-invasive: Our slogan says it best "Leak Detection Without Destruction." We are the World leader in the accurate, non-destructive detection of all types of leaks including hidden water and sewer leaks.

  • Save Money: Our non-invasive methods assure a timely and economical outcome and ensure that damage to property is eliminated or reduced.
  • Upfront Pricing: We find our customer prefer and accurate price based on us accurately inspecting the situation and making recommendations. Many service companies will quote any price over the phone because they know people may be shopping for the lowest price. Therefore, many phone quotes are inaccurate and change after a technician sees the job. We feel this method is Not Fair to customers. After speaking with our office, you will know up-front what your cost will be to detect the leak.
  • Licensed-Insured: Have peace of mind knowing that we have been thoroughly checked and are licensed and insured.
