How much does a Slab Leak cost?

Most reroutes at Streamline Plumbing fall between $1000 and $1500 but some are as low as $750. and some are as high as $2400 worst case scenario. Electronic leak detection is always free with streamline plumbing when contracted.

What to do if you think you’re having a Slab leak

1st check for positive signs that you are having a slab leak:

Water on floors

crossing lines (hot water coming out of the cold side)

low amount of hot water

High water bills

able to feel hot areas underneath your floor

mildew scent

if you notice water in the yard or in the house coming up from underneath the floor

Be sure to double check that the water isnt coming from another leak source (one which is above ground for instance)such as your shower, toilets, faucets etc.

Once you are sure that nothing else is the cause of the leak

and that no water is running inside your house then go to your water meter which is outside of your home (usually by the entrance to your driveway underneath a stone block) and look for the leak indicator which is a small triangle or star on the face of the meter, if the symbol is moving even if its very subtle then that is a sure indicator that you do have a leak. If you go to your shut off valve on the outside of your house and turn off the water and the meter stops running then that means that the leak is to a supply fixture in your home. If the indicator does not stop moving when you shut the water off to your house then that means that the leak is on the service line going to your house, these can sometimes be underneath dirt or grass rather than a slab which can be a lot cheaper for you.

beware of the following when shopping for a slab leak detection expert:

Breaking into a slab without positive confirmation of a leak location is unacceptable. Don’t let anyone dismantle your property just to search for leaks. Finding a slab leak requires a thorough process with technical expertise.

Locating leaks non-destructively requires the use of modern tools such as electronic amplification equipment and electromagnetic pipeline locators. With the proper equipment, leaks can be found and repaired with minimal disruption to property. In many cases, only a single floor tile needs to be removed and replaced.

Streamline Plumbing  highly trained leak detection technicians use our own non-invasive leak detection equipment to accurately locate the leak to save time, money and avoid unnecessary property damage.

Common ways we repair slab leaks

  • Spot repair: open up the slab at the spot of the leak and repair leaking pipe. This option is cost effective for newer construction.
  • Repipe or Reroute: replace the entire line that was leaking. This is most effective for older plumbing systems that have a history of leaking.
  • Epoxy pipe coating: in-place pipe coating is applied through the inside of plumbing. This is mostly prescribed for a system that has a series of small leaks rendering the normal repair cost prohibitive or if it is too inconvenient to dig up the slab.

What is a Slab Leak?

Slab Leaks are pressurized plumbing and pipe leaks which can occur beneath the concrete or slab within your house or anything built on slab foundations. These types of leaks can occur with either the hot line or the cold line. Slab leaks most often occur within the houses incoming water line, but sometimes are known to take place within sewer lines. Both types of leaks can cause large amounts of damage to the foundation. If you have a leak in the incoming water line it will never stop leaking because the water pressure of that line will continue to flow water out through the hole and it will continually increase the size of the hole in your pipe. This will result in major damage over time since water will be leaking out with increasing frequency. When these leaks are above the ground they are known as pinhole leaks.

We also do PEX repipes


If we are unable to offer epoxy restoration to your water system we can still help. We highly recommend a new non-metallic PEX water system for replacement systems due to the pitting corrosion now affecting our copper pipe systems. A PEX water system will cost less and last longer than a new copper system and comes with a limited lifetime warranty. Copper boasts a 50 warranty but the fine print excludes corrosion, we see copper failures due to internal pitting corrosion everyday in our business.

Will Homeowners insurance cover a Slab Leak?

The short answer is maybe. If they do cover it, there will be some qualifications, and only a claims adjuster for your company can tell you for sure. Your leak will need to be inside the walls of your foundation. You don’t have yard insurance, you have home insurance so a leak on your service line outside of the foundation will not be covered. Sorry. On the bright side, if that is your leak problem, it is likely the least expensive kind of hidden underground leak to repair. If the leak is on the pressure side of your plumbing and the water under the house comes up through the slab and causes damage to your home or belongings, some portion of the work is very likely to be covered. If you do not have damage to the above slab portions of your home, and the leak is inside the walls of the foundation, but still below the concrete slab floor, you may still be in luck. When you call your homeowner’s insurance company, they may say that they will pay to find the leak, but not to repair the leak. Have no fear! This means that the company will likely pay for the leak detection, pay to remove the slab, and whatever fill stands in the way of repairing the pipe. The company will likely not pay for the actual cutting of the pipe, the pipe and fittings to repair the leak, and the labor to repair the pipe. Then they are likely to cover the cost of fixing your home back to the original shape it was in before the work was started. Only a claims adjuster can tell you for sure, and some companies may not cover any of this at all.
