Frederick is a former coal-mining town that has become a fast-growing family suburb, so most homes are newer and a full repipe usually follows a specific failure, with older houses near the original town as the exception. Your water provider depends on which side of I-25 you live on. Call the number on this page to be connected with a local plumber in Frederick.

When repair turns into replacement
- Leaks at the same fitting type in more than one room
- Pinholes or corrosion on older copper lines
- Pressure that has dropped at several fixtures over time
- Gray plastic supply pipe stamped PB
- Water damage repairs that keep coming back in the same walls
A single leak on otherwise healthy pipe is a repair. A pattern across the house is the cue to talk about replacing lines.
Frederick conditions
Frederick was founded as McKissick and renamed for Frederick A. Clark in 1907. Along with Firestone and Dacono it forms the Carbon Valley Tri-Towns, and it has grown quickly into a family suburb. The fact sheet does not include a year-built breakdown, but that growth means most houses are relatively young, while the older homes near the original town site are the likelier candidates for a full repipe.
Three entities supply drinking water inside town limits. All residents east of I-25 are Town of Frederick water customers, Left Hand Water District serves residents west of I-25, and Central Weld County Water District serves part of town. Town water is Colorado-Big Thompson water from Carter Lake, treated at the Carter Lake Filter Plant and disinfected with chlorine. The Town has inventoried its service lines as state and federal rules require, and residents can ask the Town at 720-382-5801 what material is recorded for their line. That inventory covers the buried service line, not the pipe in your walls.
If your home has an irrigation system, note that Frederick requires reduced pressure backflow assemblies for irrigation; double check assemblies are not allowed. A plumber reworking supply lines near the irrigation tie-in should keep that in mind.
Cost factors
- Scope: a section, a zone or every line in the house
- House layout, including two-story runs and finished basements
- PEX or copper
- Irrigation and backflow connections that need to be reconnected
- Patching after access openings
What happens when you call
You will be connected with an independent local plumber who works in Frederick. Share the build year, the pattern of leaks and whether you are east or west of I-25. The Town of Frederick Building Department at 401 Locust Street handles permits and inspections, and inspectors may verify the identity of the plumber at inspection, so the plumber you hire should be the one on the permit.
