If your Lone Tree meter registers use with nothing running, or part of a floor turns warm or damp, a supply line under the concrete may be leaking. Water comes from different districts on each side of I-25, and in the Southgate area owners own their private water service lines. Call the number on this page to be connected with a local plumber in Lone Tree.

Lone Tree is a planned, relatively new city at the I-25 and C-470 junction, built around Park Meadows and the RidgeGate community. Water and sewer depend on location: Southgate Water and Sanitation Districts serve the area west of I-25 with water from Denver Water, Parker Water and Sanitation District serves east of I-25, and Northern Douglas County Water and Sanitation District serves some homes in Terra Ridge. Because most homes here are newer, a slab leak is more often a failed fitting or construction damage than worn-out pipe. Plastic lines are common in homes of this age; they resist corrosion, but a crimp or push fitting can let go, and pipe kinked during framing or a concrete pour can start leaking years later. Many homes have basements, and a basement floor is a slab with supply lines running below or inside it. Inside the house, pipe beneath the floor is private plumbing whichever district serves you.
What to do now
- Confirm with the meter. Turn off every fixture and irrigation zone, read the meter, wait an hour, read it again.
- Eliminate easy causes. Listen for toilets refilling and check outdoor spigots.
- Split hot from cold. Close the water heater's cold inlet. If the meter stops, suspect a hot line.
- Feel the floors. Walk barefoot across tile and basement floors and note any warm areas.
- Control damage. If water is coming up, shut the main and move rugs and furniture.
- Get it pinpointed. A plumber should pressure test and listen before any concrete is cut.
Symptom guide
| Symptom | Likely cause |
|---|---|
| Warm path across tile | Hot line or fitting leaking under it |
| Meter moving, floors cool | Cold-side leak or a leak on the yard line |
| Damp basement carpet | Water rising through the slab |
| Poor pressure in one room | Leak on the line feeding it |
| Water heater rarely resting | Hot water escaping |
What drives cost
- Time needed to isolate and pinpoint the leak
- Spot repair through the concrete versus a reroute through walls and ceilings
- Tile, wood or a finished basement over the leak
- Drying and repairing anything that got wet
- City permits: Lone Tree requires permits for work on plumbing systems, including replacing them, though repairing a drain or supply leak typically does not need one; applications go through the Accela portal
A plumber can tell you which category your job falls into once the leak is found.
