What Is a Concrete Slab Leak?
A concrete slab leak refers to a water leak that occurs in the pipes running inside or beneath the concrete foundation of your home. These pipes may be part of your plumbing system or even the sewer line.
Concrete slab leaks can occur in both newly built homes and older properties, although older homes are more susceptible due to the age and wear of their plumbing systems.
When a leak develops under your slab, water can seep through the concrete, causing damp spots or even standing water on the floor. If left unaddressed, slab leaks can result in significant property damage, including mold growth, higher water bills, and the erosion of the foundation, potentially weakening the structure of your home.
What Causes Concrete Slab Leaks?
There are several potential causes of concrete slab leaks. Some of the most common include:
- Corrosion: Outdated metal pipes, such as galvanized plumbing, or defective polybutylene pipes can deteriorate over time, leading to leaks in or under concrete slabs. This issue is especially pronounced in areas with hard water.
- High Water Pressure: Excessively high water pressure can strain your pipes, causing them to burst or develop leaks. This is often a problem in homes with poorly regulated plumbing systems.
- Ground Movement: The soil beneath your home can shift due to factors like earthquakes, heavy rain, or even tree root growth. This movement can put pressure on pipes, leading to cracks or fractures that result in leaks. We have several articles that break down the effects of ground movement on concrete slabs in Texas, California, and Oklahoma
- Improper Installation: In some cases, the initial installation of pipes may not have been done correctly. Issues like poorly fitted joints or pipes that were bent too tightly during installation can lead to leaks over time.

How Can I Detect a Concrete Slab Leak in My Home?
Recognizing the signs of a concrete slab leak early can help mitigate further damage. We have put together a list of six key indicators to watch for:
- Increased Water Bills: A sudden spike in your water bills, especially if your water usage hasn't increased, is often a sign of a hidden leak under your slab.
- Damp Spots on the Floor: Wet areas or puddles that have no obvious source could result from water leaking from pipes beneath the slab.
- Hot Spots on the Floor: Warm or hot areas on your floor may indicate a hot water line leaking underneath, particularly if the leak involves your home's heating system.
- Cracks in the Foundation or Walls: Over time, water eroding the soil around your slab can cause the foundation or walls to crack as the structure shifts.
- Mold or Mildew Smell: A musty odor in your home, especially near the foundation, can be a sign of mold growth, often triggered by water leaks under the slab.
- Low Water Pressure: A slab leak can cause a sudden drop in water pressure or other water pressure problems.
What Is the Best Method for Repairing a Slab Leak?
Generally, there are two main options to consider when deciding how to repair a slab leak: in-slab repair or a full home repipe.
In-Slab Repair
In many cases, the first thought might be to break open the concrete slab and repair the damaged pipe directly.
While in-slab repairs partially address the problem causing the slab leak, they are invasive, costly, and often provide only a temporary fix. The concrete slab must be jackhammered to expose the pipes, and multiple areas may need to be dug up.
This process is disruptive and expensive, with some repairs costing more than a full home repipe. Additionally, it does not fix the underlying issues with your home's plumbing system.
Repiping Your Home
The most effective and long-lasting solution to a slab leak is a complete repiping of your home's plumbing system.
This method avoids invasive drilling into your foundation. It is a more comprehensive solution as it not only resolves the immediate problem but also prevents future slab leaks.
At Repipe Specialists, all of our repipes bypass the concrete slab entirely, rerouting pipes through walls, ceilings, and attics.

How Much Does It Cost to Repair a Concrete Slab Leak?
The cost of repairing a concrete slab leak can vary significantly depending on several factors.
Repairing a single pipe under a concrete slab doesn't address the underlying problems with your home's plumbing. The price of individual concrete slab leak repairs can quickly escalate if multiple areas of the slab need to be dug up or if a new section of pipe fails. We have also seen many in-slab repair quotes exceeding the cost of a full home repipe.
A complete repipe typically ranges from $4,500 to $15,000, depending on the size of your home, the number of plumbing fixtures, and the materials used. While this may seem like a higher initial investment, it can save you money in the long run by preventing further slab leaks and providing you with a more reliable plumbing system.
