Slab Leak Detection & Repair in Fort Collins, CO
A warm spot on the floor, especially near a garage or foundation edge, is one of the more distinctive signs of a slab leak. Fort Collins 24/7 Plumbing locates and repairs slab leaks with electronic detection equipment before any concrete gets opened up. It's one of the more anxiety-inducing calls we get, since "leak under my foundation" sounds catastrophic, but with the right detection equipment, most slab leaks are a contained, fixable problem rather than a structural crisis.
Why Slab Leaks Happen
Slab leaks typically develop where a hot or cold water line runs beneath the concrete foundation, most often failing at a joint or a spot where the pipe rubs against rebar or gravel over years of minor ground shifting. Homes with copper supply lines under the slab are somewhat more prone to this than newer PEX installations, since copper pinhole leaks develop through gradual pitting corrosion.

How We Locate a Slab Leak Without Guessing
Acoustic listening equipment and thermal imaging are used together to pinpoint the exact location of a slab leak before any concrete is broken. Once the location is confirmed, the specific repair approach, whether a direct spot repair through the slab or rerouting the line above the floor, depends on the leak's exact position and the home's layout.
Direct Spot Repair vs. Line Reroute
Direct Spot Repair
- Concrete opened only at the confirmed leak point
- Lower cost when the leak is in an accessible spot
- Fastest option for most locations
- Not always feasible depending on layout
Line Reroute
- Avoids breaking concrete entirely
- Reroutes the line above the floor or through a wall
- Sometimes the better long-term option for copper slab lines
- Higher cost than a simple spot repair

Reducing Slab Leak Risk in Older Homes
There's no way to fully prevent a slab leak in a home with copper lines under the foundation, since the pitting corrosion that causes them develops from the inside over years. What you can do is act quickly on early signs, a warm floor spot or an unexplained water bill increase, rather than waiting to see if it resolves on its own. Homes that have already had one slab leak are statistically more likely to develop another elsewhere in the same copper line network, so we'll flag that risk honestly after any repair.
Common Questions
Do you have to break my whole floor to fix a slab leak?
No, detection equipment pinpoints the exact spot first, so any concrete work is limited to that location, or avoided entirely with a reroute.
How urgent is a slab leak?
It won't flood your home suddenly, but it wastes water continuously and can damage flooring over time, so it's worth addressing promptly once confirmed.
Will my flooring be damaged during repair?
Some flooring disturbance is likely at the repair point itself. We'll walk you through what to expect for your specific flooring type before starting.
