Need an estimate?

A leak in an underground water pipe can be a severe problem, leading to flooding, property damage, and high water bills. Fortunately, a leak detection service can help you avoid these issues.

Leak detection services involve using special equipment to locate and repair leaks in your underground water lines. There are many benefits to using underground leak detection services, including: 

Leak Indicators

Water leaks can occur anywhere in your home, but they are tough to detect when they happen underground. Fortunately, a few telltale signs can help you identify an underground water leak.

One of the most common indicators is a sudden spike in your water bill. You may have a leak if you notice that your bill has increased significantly without any explanation. Wet or mushy spots in your yard, even when there hasn’t been any rain, may also indicate water leaking from a pipe underground.

Early Detection is Key

If you suspect that you have a water leak, contact us immediately. The sooner the leak is found and repaired, the better. We serve Northern Virginia, Maryland, and Washington, D.C.

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.*

Our Leak Detection Process

Most people are familiar with the visible signs of a water leak, such as pooled water or stained ceilings. However, many leaks occur underground, where they are much more difficult to detect. 

Line Locators, Inc. offers innovative underground water leak detection services. We use cutting-edge technology to quickly and accurately locate leaks. With our high-end private utility line location equipment, we can verify the path and determine the depth of your water line. 

Next, we use an amplified digital acoustic device with specific ground microphones to determine the highest reading. We even have microphones that can fit inside a pipe to locate the highest leak sound.

Of course, even with all the state-of-the-art equipment at our disposal, it would be futile if we don’t know how to use any of it. That’s why we constantly train and test new equipment and techniques to stay up-to-date with the latest technology.

Reasons to Detect Leaks

A water leakage detection service can save you money, protect your home from water damage, and even help improve your home’s energy efficiency. A leak detection service can locate hidden leaks in your home’s plumbing system, saving you the cost of expensive repairs. Both residences and businesses can benefit from this essential service.

Insurance Claims

We understand that a leak detection service is an out-of-pocket expense that not everyone can afford. In addition, homeowners insurance claims for leak detection can be costly. The average leak detection claim is over $4,000; some leak detection services can cost upwards of $10,000. 

We can charge you directly for reimbursement against your deductible, or we can charge the insurance company directly. Contact us to discuss your options.
