What is a Slab Leak?

A slab leak is the industry and insurance term for a leak in one of the water lines running below the concrete floor of your home. When these leaks are above the floor they are known as pinhole leaks.

Why do I have a leak?

In our opinion, based on inspecting 100’s of leaking lines, the leaks are primarily the result of a reaction between our drinking water and the copper pipes. We used to believe that leaks resulted from bad installation practices, non-reamed pipe, too much soldering flux, contact with concrete, rebar or rocks but that has proven to be a cause in a very low percentage of our inspections. Check out our slab leak information page for more.

How do you find the leak?

We use our experience on how your system is installed along with electronic listing and tracing equipment to help us locate the problem. Visit the leak detection page for detailed outline of the location process.

How do you fix the leak?

We utilize all common industry fixes along with our single line epoxy repair system. After the leak is located and isolated we will talk with you about the different options for repairing your specific problem and the associated costs. Our goal is to help you make the best decision for your specific situation. Visit our Slab Leaks page for repair options and descriptions.

What will my home owner’s insurance policy cover?

This varies between insurance companies. Generally you can expect your insurance company to cover the cost of the leak detection service, line access and isolation, dry out and restoration of your property to the condition before the leak occurred. The insurance companies will normally not cover the cost of the plumbing repair. Please note that we see exception to ALL of the above on a regular basis and insurance company responses will vary job to job with the same company and from company to company for the same problem. If you have an agent you can speak with without filing a claim then that is your best option for knowing what your coverage will be.

How Is a Slab Leak Repaired?


With “direct access repair” we cut the cement slab and repair the leaking pipe. We then test the system for any additional leaks to make sure everything is running perfectly. Then we compact the hole and re-lay new concrete, fixing it all up so it is good as new.

Another option we offer is to re-route the line. This means we take a full section of the line and replace it from one manifold above the slab to another. An example of this would be if a line running from the water heater to the kitchen faucet were leaking. We would re-route the line from the water heater to the manifold located behind the kitchen sink.

Which method of plumbing repair would be the more efficient and cost-effective will depend on the situation and the size of the slab leak.


What are the different types of repair options for slab leaks and what are the benefits to each?

For residential properties the most common solution is a reroute and for commercial properties the most common solution is a direct repair. A direct repair is when we jackhammer into the floor to expose the pipe and a reroute is when we cancel the line and re-direct the line overhead. Typically residential property homeowners don’t want to ruin their flooring so a reroute is a cost effective and non-invasive solution. Every situation is different and I make sure to talk with my customers to make sure we determine the best fit for them, whether that’s a cost-effective solution or the most long-term solution like a repipe which is when we reroute all of the water lines under the slab.

What is your leak location process.?

If it’s a hot water slab leak it’s easier to locate the leak because of the hot spots. Cold water slab leaks require an analysis of the home to check each fixture by pressurizing the line with a pressure gauge on one of the hose bibs to see if the gage level drops. Once it’s determined it’s a cold water slab leak, I use an electronic sound devise that allows me to hear and pinpoint leaks under a concrete slab. The location process usually takes between one and two hours. An experienced slab leak locator will be able to precisely locate the leak in most cases. There are situations that can hinder an exact location (i.e., leaks under shower pans and cabinets), however a leak location can still be performed successfully.
