Slab Leak Detection & Repair in Kent, WA
A warm patch on the floor with no obvious cause is one of the more specific signs of a slab leak, a leak in the water line running beneath your home's foundation.
What A Slab Leak Actually Is
A slab leak happens when a water line running underneath a home's concrete foundation develops a leak. Because the line is buried in the slab itself, the leak isn't visible the way a leak under a sink would be. It often shows up first as a warm floor patch, a higher water bill, or the sound of running water when nothing's on.
Left alone, a slab leak can undermine the soil beneath the foundation over time and cause real structural concern, on top of the ongoing water waste. Catching it early keeps both the repair and the water damage smaller.
Signs Of A Slab Leak
Warm Spot On The Floor
A patch of floor that's noticeably warmer than the rest, especially over a hot water line, is a classic slab leak sign.
Sound Of Running Water
Hearing water running when every fixture in the house is off points to water escaping somewhere in the system.
Unexplained Water Bill Increase
A slab leak can run for weeks before it's visible anywhere, showing up first as a jump in your water bill.
Cracks In Flooring Or Walls
Foundation movement from a long-running slab leak can eventually show up as new cracks in flooring or nearby walls.
A Warm Floor Patch Is A Specific Sign, Not A Coincidence
If you've noticed one spot on your floor that's warmer than the rest, that's not a random quirk of your house. It's a strong sign of a hot water line leaking underneath the slab at that exact location. Combined with a rising water bill or the sound of running water, it's worth having checked before the leak has a chance to affect the foundation area.
Before We Arrive
Don't Cut Into The Slab Yourself
Attempting to expose the line without detection equipment risks striking electrical or other buried lines, and it rarely finds the actual leak.
Note Where The Warm Spot Is
Mark or photograph the exact location and how large the warm area is. It helps narrow the search before we even arrive.
Track Your Water Meter
Note a reading and check it again after a few hours with everything off, to help confirm the leak's severity.
Watch For New Cracks
If you notice a new crack in flooring or a nearby wall, mention it right away since it can affect how urgently the repair should happen.
Finding And Fixing The Leak
We use acoustic detection to listen for the specific sound of pressurized water escaping under the slab, combined with thermal imaging to trace the warm water line's path. This narrows the leak's location closely before any concrete is touched.
Repair options depend on the leak's location and the home's plumbing layout, ranging from a targeted slab penetration to rerouting the line above the floor instead of repairing the buried section directly. We'll walk you through the option that makes sense for your specific situation and your home's layout. Any repair follows the Uniform Plumbing Code (UPC) that Washington has adopted statewide.
Warm Floor Patch Or Rising Water Bill?
We'll find the slab leak before it does more damage.
What Affects The Price
Free written estimates on non-emergency calls; emergency work gets an upfront price before anything starts. Sudden slab leaks are sometimes covered by homeowners insurance, though coverage for the concrete work itself varies by policy. We recommend confirming with your insurer.
Common Questions
It's worth addressing promptly. Left alone, it can affect the soil under the foundation and cause real structural concern over time, on top of ongoing water waste.
No. Acoustic and thermal detection let us narrow the leak's location closely, so the repair opening is small and targeted rather than a large section of slab.
In many cases, yes. Rerouting the line above the slab avoids disturbing the foundation at all, depending on your home's layout.
Sudden slab leaks are often covered, though specifics vary by policy. We recommend confirming your coverage with your insurer.
