How to Fix a Slab Leak?

The reason for a slab leak is when water supply or drain pipes located beneath the concrete slab foundation of your home crack, rupture, or are otherwise damaged. The most frequent causes of slab leaks include pipe corrosion, friction, erosion, poor installation, and excessive water pressure.

Your water bill may not be the only thing these leaks might affect. They may result in foundation damage and catastrophic damage to your house and property. Erosion that results from long-term neglect can seriously harm the structure of your house, which is much more expensive to fix than a slab leak in Flower Mound.

Some Ways to Fix a Slab Leak

Low water pressure or an abrupt loss in pressure might be signs of a serious slab leak. The best course of action is to call a plumber in Flower Mound, TX, if you notice damp areas on the floor or hear running water or hissing without being able to identify the cause.

Here are some techniques through which the plumber will try to fix the slab leak:

Rerouting or Repiping

Plumbers will repipe the house instead of fixing the existing pipes when the leak includes several pipes. They set up a brand-new plumbing system consisting of copper, CPVC, or PEX, which are more resilient materials than those normally utilized in the original pipes for slab foundations. Occasionally the expert for a slab leak may reroute your pipes, so they go through the walls and attic of your house rather than under the foundation.

The Pipes Need to be Fixed

When the plumber knows the precise source of the leak, repairing the pipes is the least expensive solution for correcting a slab leak. Using infrared thermometers and tracing equipment, the plumber can locate the leak.

After that, they fix the pipe by drilling a hole in the floor. In the Argyle area, a plumber charges $200 to $350 for a pipe repair.


If you don’t want to cause inside damage to your home, tunneling under the house is an option for jackhammering holes in the floor. When the plumber locates the leak, the team will repair it by excavating an access hole adjacent to the nearest wall and a tunnel beneath your home.

This procedure is typically the most expensive since you must also pay labor costs since it typically calls for a whole excavation crew. Tunneling is the greatest choice if preserving the internal integrity of your home is a goal because it is the least intrusive. For the most difficult tasks, expenses might range from $2,500 to more than $20,000.

Lining a Pipe

When a plumber in Flower Mound, TX, locates the hole in a pipe and injects epoxy into the imperfection, the old pipe is lined, and any leaks and holes are sealed, completing the pipe lining, also known as epoxy repair. Although this is a less expensive repair option, there is considerable debate over its effectiveness.

Bottom Line,

It is better to call a professional plumber if you notice a slab leak before the issue worsens and increases the damage.
