Signs of a slab leak
- An unexplained warm patch on part of your floor, especially over a hot water line
- A water bill that's climbed noticeably with no obvious explanation
- The sound of running water when every fixture in the house is off
- Cracks appearing in flooring or along a nearby wall
- Damp carpet or flooring in a spot that isn't near any visible plumbing
- Noticeably low water pressure throughout the home
These signs are easy to dismiss individually — a warm spot could just be sunlight, a higher bill could just be a busier month. Together, especially in a home with a slab foundation, they're worth taking seriously.
What causes slab leaks
- Pipe corrosion. Supply lines running through or under a slab can corrode from the inside over years, eventually developing a pinhole leak.
- Ground shifting. Soil movement beneath the foundation puts pressure on pipes that have little room to flex.
- Abrasion. Pipes rubbing against concrete or rebar during normal ground movement can wear through over time.
- Poor original installation. Pipe that wasn't properly wrapped or supported before the slab was poured is more prone to early failure.
- High water pressure. Consistently high pressure stresses pipe walls, accelerating existing weak points.
What to do before you call
- Check your water meter with everything in the house turned off — if it's still moving, water is escaping somewhere.
- Note where you've noticed warmth, dampness, or new cracks, and roughly how long it's been happening.
- Avoid trying to open the floor yourself — locating the exact point of the leak first prevents unnecessary demolition.
- If you can, check your water bill against previous months for a jump that lines up with when symptoms started.
How we locate and repair it
We start with how we pinpoint hidden leaks using listening equipment and other non-invasive methods to find the exact location of the leak before any demolition happens. That single step is what keeps a slab leak repair from turning into tearing up more of your floor than necessary.
Once we've confirmed the location, we discuss your repair options, which may include accessing the pipe directly through a small section of slab, or rerouting the line above the slab entirely to avoid disturbing the foundation again in the future. If the pipe shows signs of failing in multiple places, we'll tell you honestly whether a complete water line replacement makes more sense than repeated spot repairs, or whether more general pipe repair work is enough to resolve it.
According to the Plumbing-Heating-Cooling Contractors Association, accurate leak location before excavation is one of the most important steps in minimizing property damage during a slab leak repair, which is exactly why we treat it as step one rather than an afterthought.
When to call a pro
Call us as soon as you notice a warm spot, an unexplained water bill spike, or any new cracking in your flooring. A slab leak that goes unaddressed can lead to significant water damage under your home and, over time, can affect the foundation itself. The earlier we can locate it, the less invasive the repair tends to be.

Frequently asked questions
How do I know if I have a slab leak?
Common signs include an unexplained warm spot on the floor, a rising water bill with no clear cause, or the sound of running water when everything is turned off. We confirm with proper leak detection before recommending repair.
Will you have to break up my entire floor?
Usually not. We locate the exact leak point first, which typically means only a small section needs to be accessed rather than a large area of flooring.
Is a slab leak an emergency?
It should be treated as urgent. The longer it goes unaddressed, the more water damage and potential foundation issues can develop underneath your home.
Can a slab leak be repaired without cutting the slab?
In some cases, yes. Rerouting the affected line above the slab is sometimes possible, avoiding the need to access the pipe through the foundation at all. We'll tell you if that's a realistic option for your home.
How much water can a slab leak waste?
It varies with the size of the leak, but even a small, steady leak can add up to a significant amount of wasted water and a noticeably higher bill over just a few weeks.
Does homeowners insurance cover slab leak repair?
Coverage varies by policy and cause. We recommend checking directly with your insurer, since we can't speak to your specific policy terms.
