Lone Tree is a newer planned city, so most faucet trouble here is a cartridge or seal wearing out rather than an old fixture failing. A plumber can usually rebuild the faucet in one visit. Call the number on this page to be connected with a local plumber in Lone Tree.
A short local intro
Lone Tree sits at the I-25 and C-470 junction in northern Douglas County, built to high design standards around Park Meadows and the RidgeGate community. Water and sewer depend on which side of I-25 you live on: Southgate Water and Sanitation Districts serve the west side, Parker Water and Sanitation District serves the east, and some homes in Terra Ridge are on Northern Douglas County Water and Sanitation District. Southgate distributes Denver Water's supply, which the 2026 report puts at an average of about 105 ppm hardness, a moderate level.
What to do now
- Close the stops under the sink. If one will not turn, use the main shutoff.
- Dry the cabinet and place a towel to catch any new drips.
- Find the source: spout, handle, base or the connections below.
- Clean the aerator if flow is weak; scale and grit collect there.
- Check the warranty on newer faucets before buying parts.
- For street-side leaks west of I-25, call Southgate at 303-779-0261. Southgate reminds owners that the buried service line is theirs.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Drip after shutoff | Worn cartridge seals |
| Stiff lever | Scale on the cartridge |
| Water under the handle | Cartridge O-ring |
| Leak at the spout base | Spout O-rings |
| Pull-down drips down the hose | Worn hose or connector |
| Puddle in the cabinet | Supply line, stop or drain |
Cost factors
- A cartridge or seal kit versus a new faucet
- Warranty coverage for parts
- Replacing stops or supply hoses while the water is off
- Access under undermount sinks and in tight vanities
- Whether the work needs a permit
On permits: the City of Lone Tree requires permits for work on plumbing systems, including replacing them, but says clearing stoppages or repairing drain and supply leaks typically does not need one. Applications go through the city's online Accela portal. Because so many Lone Tree homes were built in the same few decades, faucets often wear out at similar times; if one sink starts dripping, it is worth asking the plumber to look at the others. If you live east of I-25, your water comes from Parker Water and Sanitation District instead of Southgate, so check that district's materials for details about your water.
