How to tell if you have a slab leak

A slab leak occurs when the pipes beneath the concrete foundation of your home develop a leak. Detecting a slab leak early can save you from significant damage and costly repairs.

Here are some common signs that might indicate you have a slab leak on your property:

1. Unexplained Increase in Water Bills

One of the first signs of a slab leak is a sudden and unexplained spike in your water bills. If you notice your water usage hasn’t changed, but your bill has increased significantly, it could be due to a hidden leak under your slab.

2. Damp or Wet Spots on Floors

Water leaking from pipes beneath your slab can seep upwards, causing damp or wet spots on your flooring. If you notice any unexplained moisture or puddles, especially on ground floors or basements, it might be a sign of a slab leak.

3. Warm Spots on the Floor

If you have a hot water line leaking under your slab, you might feel warm spots on your floor. These warm areas can be a clear indicator of a slab leak, especially if the rest of your floor is cool.

4. Low Water Pressure

A slab leak can cause a drop in your home’s water pressure. If you notice that your water pressure has decreased and there’s no apparent reason for it, a leak under the slab could be the culprit.

Slab Leak Repair FAQs

How do I know if I have a slab leak under my home?

Slab leaks often reveal themselves through subtle yet telling signs: an unexpected spike in your water bill, damp or warm spots on the floors, unexpectedly low water pressure, or even bubbling paint. If you experience any of these issues, Bonney’s licensed plumbers can perform a precise leak detection service, helping identify hidden problems before they escalate.

What happens during a slab leak diagnostic appointment?

When you request service, Bonney sends a licensed plumber equipped with advanced tools like electronic leak detectors, infrared imaging, and acoustic listening devices. For a $99 diagnostic fee (which is waived if you choose us for repairs), the plumber will locate the leak, explain your options, and recommend the most effective and minimally disruptive repair method. 

Can slab leaks be repaired in just one visit?

Yes, most slab leaks can be repaired the same day. Bonney’s technicians come prepared for detection and repair work, enabling them to address the issue in a single visit. Whether it’s a targeted spot repair or rerouting the pipe, the goal is to resolve the problem quickly and efficiently. 

How much does slab leak repair usually cost, and what affects the price?

In the Sacramento area, Bonney’s slab leak repair costs typically range from $1,500 for accessible fixes to around $4,500 on average, and up to $9,000 for more complex cases. The price varies based on factors such as leak location, necessary detection methods, repair complexity, and any additional plumbing work required. 

What are the long-term risks of ignoring a slab leak?

Ignoring a slab leak can lead to severe structural and health consequences. Over time, the leaking water can erode the foundation, weaken flooring materials, and promote mold growth beneath the surface — costly and hazardous issues to fix. Even minor leaks can cause unseen damage that worsens with time, so addressing them early is crucial. Bonney’s expert team helps homeowners avoid these risks by offering fast, precise repairs that protect the home’s integrity and its occupants’ safety.
