Slab Leak Detection & Repair around Fort Collins
Homes built in Fort Collins' newer subdivisions south of Old Town and along the Harmony Corridor are almost universally slab-on-grade, with copper or PEX supply lines poured directly into the concrete foundation. When one of those lines develops a pinhole or a fitting fails, there's no crawl space or basement to catch the water; it moves under the slab and shows up wherever the concrete happens to crack or the moisture finds an edge.
The failure itself is usually mechanical rather than a water quality problem: a section of copper rubbing against gravel or rebar during decades of minor ground movement, or a fitting that was never quite seated right at the pour. Locating it precisely, instead of jackhammering a large section of floor on a guess, is what separates a contained repair from a much bigger one.
Copper pipe run directly through concrete without a protective sleeve is the single biggest risk factor for a future slab leak, since decades of minor ground settling lets the pipe rub against gravel or rebar until it wears through. It's worth knowing whether your home's original plumbing was sleeved, since that detail shapes how likely a repeat leak is elsewhere in the same slab.

What a slab leak detection & repair visit looks like
We confirm a slab leak with a pressure and flow test first, since a hot spot on the floor or a spike in the water bill can sometimes come from something else entirely, like a water heater or an irrigation line.
Once confirmed, we use listening equipment to mark the leak's location as precisely as possible, then cut the smallest access point in the slab needed to repair or reroute the line, patching the concrete when the repair is done.
Once a slab leak is repaired, we pressure test the full system again before closing the access point, confirming the fix holds rather than assuming a single successful repair means the job is done.
The biggest cost factor in a slab leak repair is how much concrete needs to be opened, which is exactly why precise location with listening equipment matters: a leak pinpointed within a few inches costs meaningfully less to fix than one found by guesswork.

QUESTIONS
Questions about slab leak detection & repair
How do I know if it's a slab leak and not something else?
A warm patch on the floor with no space heater nearby, a sound of running water when everything's off, and a rising water bill together are strong signs. A pressure test on the plumbing system confirms it before any concrete gets touched.
Will the repair mean tearing up my whole floor?
Usually not. Once the leak is located with listening equipment, the access opening is typically limited to the specific section of slab where the failed line sits, not the entire floor.
Can a slab leak be rerouted instead of repaired at the same spot?
Often yes. Rerouting the line through a wall or overhead instead of back into the slab can avoid reopening the same vulnerable path, and we'll walk through which option fits your home.
If I've had one slab leak, will I get another?
It depends on whether the original copper was sleeved and how it was routed. If one section is failing from age or friction, similar unsleeved sections elsewhere in the slab carry a higher risk, which is worth discussing honestly rather than ignoring.
Is rerouting always more expensive than a direct repair at the leak?
Not necessarily. Rerouting avoids reopening the slab in a vulnerable spot, and depending on the home's layout it can sometimes be comparable in cost while offering a more durable long-term fix.
Will my homeowners insurance help with a slab leak?
Coverage varies by policy, some cover the cost to access and repair the leak but not the resulting floor or slab damage. We can document the plumbing side clearly for your claim either way.
