How Much Does It Cost to Repair A Slab Leak?

Best value: a full repipe is a permanent fix to slab leaks

Slab leaks occur when a freshwater line or sewer line located beneath or within a home's concrete slab begins to leak, potentially causing significant damage and costs.

The cost of repairing a slab leak varies depending on the repair method you choose. In this article, we will focus on the cost of repairing slab leaks caused by failing incoming freshwater lines.

If you've experienced a slab leak, you'll need to compare the cost of an in-slab repair to the cost of a complete repipe. At Repipe Specialists, our complete repipes typically range from $4,500 to $15,000, depending on the home's size and complexity.

We'll cover the costs associated with both in-slab repairs and full home repipes—and explain why we believe a complete repipe is always the most cost-effective solution for slab leaks.

How Much Does It Cost To Repair A Slab Leak?

The costs associated with repairing a slab leak can vary greatly depending on how you decide to repair the leak. There are two types of slab leak repairs to consider:

  1. In-slab repair: This requires opening large (and often multiple) portions of the slab with a jackhammer and then relaying concrete in the middle of your home.
  2. Complete repipe: At Repipe Specialists, our repipes do not require cutting into the concrete slab. Instead, we cap off the freshwater lines that are already in or under your slab, leaving them in place. Then, we route all your new plumbing through walls, ceilings, and attics, completely bypassing the slab and preventing future slab leaks.

For the remainder of the article, we will discuss the process and costs associated with these two slab leak repair options.

In-Slab Repair: Partial Slab Leak Solution

We consider an in-slab repair a "temporary" solution because whatever caused the slab leak initially has a high likelihood of occurring again in another part of the slab. You can also visit our article that covers the common causes of slab leaks, ranging from faulty old pipes to shifting soil.

In-slab repairs partially address the issue causing the slab leak, but they can be both intrusive and expensive. In fact, we've come across in-slab repair quotes for a single section of leaking pipe that exceeded the cost of one of our full home repipes.

Multiple repairs can accumulate over time, causing costs to skyrocket well beyond the expense of a full home repipe, often reaching tens of thousands of dollars.

A Complete Repipe: Permanent Slab Leak Solution

A complete repipe might sound like a more expensive option compared to a single in-slab repair. However, we always recommend a full home repipe as the best option for several reasons:

  • Less intrusive: Jackhammering (and later pouring) concrete in the middle of your home will always be messier and more intrusive than our whole-home repipe process.
  • Routing new PEX tubing through walls

  • Completed in 1-2 days: In-slab repairs often take much longer than whole-home repipes, which can typically be done in one day, with wall patching on a second day.
  • Guarantee against future slab leaks: After a repipe, you'll no longer have incoming water lines in your slab, so it simply isn't possible to suffer a slab leak again.
  • Lower cost: The costs of repeated in-slab repairs and associated water leak damage will almost always exceed the one-time cost of a whole-home repipe.

For a detailed look at what is involved in a full home repipe, you can read our step-by-step repipe timeline.

We've also completed many repipes for homeowners who had no plumbing issues but chose to be proactive in order to avoid the headaches and costs associated with unplanned slab leaks.
