We can help you find an array of leaks including main line service lines in the yard, leaking pipes in the slab of your house or business, pool leaks, sewer pipes or duct work.

Have you:

If you have answered ‘yes’ to any of these, you may have a leak. Don’t worry, we can help!

Need an estimate?

Call us to explain what’s going on and we will offer suggestions on how we can service you. Our highly-trained technicians can find the highest leak reading so your plumber can repair the leak. Whether the leak is in a hot water line, the main line from the city water meter to the house, inside or outside, under the grass, under the concrete slab or an asphalt parking lot, etc we have equipment that can pick up those leak sounds. 

Save yourself time, money and stress – hire a leak detection pro rather than allowing someone to just start digging or jackhammering your floor! A contractor makes more money on convincing you to replace the entire pipe versus doing a spot repair. Of course, the repair is much less costly to you! Sometimes it makes sense to replace a line versus repairing it, but know your options and cost differences. Give us a call and we will give you a quote over the phone for the leak detection. We find leaks all day long and can tell you exactly where the leak is.*

How do we find a leak and what equipment do we utilitize?

Line Locators Inc. uses specific, high end private utility line location equipment to verify the path and may be able to give you the depth of your water line. Next we use an amplified digital acoustic device with specific ground microphones to verify the highest reading. We even have microphones that can go inside a pipe to locate the highest leak sound. 

Of course we have all sorts of high tech equipment like digital leak correlators that municipalities, industrial settings and large commercial properties like to see on site. Sometimes GPR (ground penetrating radar) and even video cameras are utilized to find leaks. Occasionally  we will need to use a trace gas like helium for very small leaks or if the site location has a high noise level where the listening devices will not work. 

Smoke testing can find leaks in sewer lines when there is a stench that lingers. The non toxic smoke is visible after it escapes a pipe through a break. Where there is smoke, there is a ….leak. 

Even with all the fancy, state of the art equipment, if you don’t know how to use any of it, it’s worthless. Our ongoing training and testing of new equipment and techniques is what keeps us ahead of the rest.

We offer homeowners insurance claim leak detection

Leaks in your home or building are found using what the insurance industry calls Cause & Origin Claims. We use a combination of infrared imaging and digital moisture meters to perform non-destructive leak detection to try to locate the cause and origin of the leak. These techniques are also used to pinpoint heating and AC leaks in the duct work, causing condensation leaks and moisture build-up behind the sheetrock.

We can bill you directly for reimbursement against your deductible or can bill the insurance company directly. Give us a call to talk about the options. 

We can detect leaks in both residential property and commercial buildings

Our industrial/commercial leak detection is able to verify the location of the smallest leaks on heat and cooling tower lines, fire systems, forced mains, air and fuel system lines, drain waste vent plumbing systems, and methane collection system.

If it’s leaking, call a professional leak detection company to save yourself money in the long run!
