In Franktown, a slab leak is a water line leaking beneath a concrete floor, such as a basement or slab-level room. Our fact sheet does not name a water provider for Franktown, so check your bill or ask Douglas County, but in every case the plumbing in and under the house is the owner's to repair. Call the number on this page to be connected with a local plumber in Franktown.

Franktown homes and water
Franktown is a small unincorporated ranching and farming community at the junction of SH 83 and SH 86, about 7 miles east of Castle Rock and 9 miles south of Parker, near Castlewood Canyon State Park. It has kept a distinctly rural identity, and properties here vary. We could not verify who supplies water to Franktown homes, and on rural land it can differ from one property to the next. If you get a water bill, the provider is named on it; if not, your home may have its own supply. That matters for testing: a meter test works on a utility connection, while on a private supply you watch for a pump that runs with nothing on.
Because Franktown is unincorporated, plumbing permits come from the Douglas County Building Division, which issues a Mechanical/Plumbing permit for unincorporated areas. Homes range in age, so the pipe under a slab could be copper, which wears against gravel, or plastic, which tends to fail at fittings.
Repair options
| Option | Works when | Downside |
|---|---|---|
| Fix through the floor | The leak is located precisely and the pipe around it is healthy | Flooring has to be opened and matched |
| Reroute overhead | The buried run is old or has leaked before | Walls and ceilings are opened along the new path |
| Repair the yard line | Testing shows the leak is between the supply and the house | Digging outside rather than work indoors |
Signs to watch
- A meter that moves, or a pump that starts, with every fixture off
- A warm area on tile or a basement floor
- Damp carpet or baseboards with no fixture nearby
- Higher water or electric bills with no change in use
Timing
A warm floor stands out most in winter, while summer watering can hide extra use, so test with outdoor water off. Rural distances can affect scheduling, so call as soon as the test points to a leak rather than waiting for damage to show. Don't leave a confirmed leak running under the concrete. Water moving under a slab can wash out the base material and wick into walls and flooring, and on a private supply it keeps the pump working far harder than it should. Once the leak is fixed, have the pump and tank checked if they were short-cycling.
