Highlands Ranch homes went up from the 1980s onward, so toilet repairs here are mostly worn-out flappers, fill valves and wax seals in fixtures that have done decades of work. Highlands Ranch Water handles the curb stop and main; the toilet and everything inside are the owner's. Call the number on this page to be connected with a local plumber in Highlands Ranch.

What happens when you call
The number on this page connects you with an independent plumber who works across Highlands Ranch. You'll be asked what the toilet is doing (running, leaking, loose or clogged), whether water has reached the floor or a ceiling below, and whether other drains are affected. If the toilet's angle stop won't close and the house main is also stuck, say so, because that changes what the plumber needs to do first.
On site, the plumber typically checks the tank internals, then the supply line and shutoff, then the seal at the floor. Many homes here still have their original builder toilets, and parts for most of them are easy to find.
Cost factors
- The repair: a flapper or fill valve is a short visit; a reset with a new wax ring takes longer.
- Several toilets at once: homes with three or more bathrooms often have the same tired parts in each, and doing them together saves a return trip.
- Underneath: a cracked plastic flange or damp subfloor adds materials.
- Clog location: a blockage in the trap is simple; one in the building drain or private sewer line takes more equipment.
- Replacement: the model chosen and haul-away of the old fixture.
- Timing: evenings and weekends usually cost more.
Highlands Ranch conditions
Highlands Ranch is unincorporated Douglas County, the most populous unincorporated community in Colorado, built as developer-named subdivisions starting in the 1980s. That makes the housing stock fairly uniform in one way: a lot of toilets and tank parts are original or on their second round, and plastic components from that era stiffen and crack with age.
Water and wastewater both come from Highlands Ranch Water, the Centennial Water and Sanitation District, which treats mostly surface water at the Joseph B. Blake plant and disinfects with chloramine. Wastewater goes to the Marcy Gulch plant. The district maintains the service line through the curb stop; the customer owns the line from there into the house. During a private plumbing emergency, the district will help shut off water at the curb stop, and its 24-hour line is 303-791-2185. For a sewer backup, it advises calling a plumber first to check the private line.
Because the community isn't a city, plumbing permits come from the Douglas County Building Division, and the Highlands Ranch Metro District has to sign off on certain projects before the county will issue one. A simple toilet repair doesn't involve either.
Before the plumber arrives
- Close the angle stop behind the toilet if it turns easily
- Know where the main shutoff is, usually near where the line enters the house
- Hold off on flushing a toilet that's draining slowly
- Note whether a tub or floor drain also backs up
- Put down towels and check the ceiling below an upstairs bathroom
