Slab Leak Repair: Cost and Options

The majority of homes in Mesa and Gilbert, Arizona have concrete slabs underneath them that help prevents clay soil foundations from cracking. While these slabs are great for reinforcing a home’s structural integrity, they can experience leaks that pose a threat to a home. 

Do you think that you might have a slab leak? Read on to learn more about how to detect a slab leak, options for slab leak repair, and cost estimates for repairing a slab leak. 

What is a Slab Leak?

The “slab” of a home is the concrete foundation that it is built on. Oftentimes, water and other sewer lines run either below or through the slab. When these lines break or deteriorate, they release water that flows underneath or into your foundation. This release of water is what causes a slab leak. 

How to Detect a Slab Leak

It’s not easy to detect a slab leak. Oftentimes, you can’t even tell you have one until a lot of damage has been done, as the most common type of leak is a pinpoint leak that slowly releases water. Here are some early signs that might point to a slab leak in your home: 

  • Higher water bills.
  • Lowered water pressure.
  • Damp carpets, floors, or baseboards. 
  • The sudden sound of running water.
  • Mold.
  • A bulge in your hardwood floor. 

The best thing you can do if you think you might have a slab leak is to hire a professional to come take a look at what’s going on. They’ll have the proper tools and equipment – like thermal imaging, moisture level meters, and video cameras – to detect and fix a slab leak. 

Slab Leak Repair Options

There are three main ways that you can fix a slab leak. 

  1. Repair: Repairing leaks in plumbing lines under your foundation slab involves using a jackhammer to break the slab open. Once the slab is open, you go in to repair the line. This option should be done by professionals who know how to use the jackhammer in a way that reduces damage. 
  2. Reroute: A reroute involves setting a new path for your water supply to go through. Generally, this new route goes around the slab rather than underneath or through it. Rerouting is a great solution as it can also prevent any future slab leaks in that water line. 
  3. Repipe: Repiping is the most comprehensive and intense solution. This involves repiping the entire house’s water lines. Normally, this is done when there is a fear that the whole home’s plumbing system is compromised. While this may sound like more work, it can prevent having to spend money on multiple expensive repairs in the future.
