What happens when you call
You will be connected with an independent local plumber who works in Larkspur. Expect questions about the house's age, what pipe you can see near the water heater, where leaks have shown up and whether you are inside town limits. The plumber looks at exposed lines and the main shutoff, then recommends a repair, a partial repipe or a full one.
If you proceed, the plumber plans routes, schedules shutoffs and arranges the permit and inspection.

Larkspur conditions
Larkspur is a small town in the East Plum Creek valley of southern Douglas County along I-25, about 11 miles south of Castle Rock, best known as home of the summer Colorado Renaissance Festival. It incorporated in 1979. The fact sheet does not include a year-built breakdown, so the age of your own home is the best guide.
The Town of Larkspur Public Works Department runs the water and wastewater systems inside town limits, overseen by a Water and Sewer Board, with the water system operated under contract by Semocor. The water comes from Denver Basin aquifer wells in the Denver and Arapahoe aquifers rather than surface water. Water emergencies inside town limits go to Town Hall during business hours and to Semocor after hours. The pages reviewed do not say where the town's responsibility for the service line ends, so the plumber should confirm before any buried line is replaced. Areas of the 80118 ZIP outside town limits are not covered by the town system and were not verified.
Inside town limits, the Town of Larkspur Building Department at 8720 Spruce Mountain Road processes building permits and SAFEbuilt performs inspections. Its page does not mention plumbing permits specifically, so the plumber should confirm what a repipe requires. Addresses outside town go to Douglas County.
Before the visit
- Confirm whether you are inside town limits
- Find the main shutoff and check that it turns
- List leaks and past repairs
- Clear access to the water heater
