In Louisville, faucet repairs range from worn washers in older downtown homes to cartridge problems in newer and rebuilt houses. Most can be fixed with new parts. Call the number on this page to be connected with a local plumber in Louisville.

What happens when you call
You will be connected with an independent plumber who covers Louisville. Describe the faucet, where water is showing up and whether the home is older or recently built. Hundreds of Louisville homes were rebuilt after the December 2021 Marshall Fire, and those houses usually have newer faucets still under warranty, so it helps to have the brand and model handy.
The plumber shuts off the water, opens the faucet and checks the cartridge or washers and seals, then explains whether a rebuild or replacement is the better route.
What affects the cost
- A cartridge or seal kit versus a complete faucet
- Warranty parts from the manufacturer on newer fixtures
- Seized stops or supply lines in older homes
- Access around undermount and farmhouse sinks
- Extra deck fixtures like filter faucets
Louisville's water and housing
Louisville is a former coal-mining town in southeastern Boulder County, now a suburban community with a historic downtown along Main Street. The City of Louisville runs two water treatment plants supplied by South Boulder Creek water stored in Marshall Lake, Harper Lake and Louisville Reservoir, along with Colorado River basin water. The city disinfects with chlorine, not chloramine, and its report does not state hardness.
The housing is a mix. Older homes near downtown can have two-handle faucets and long-untouched stops. Newer neighborhoods, including the many homes rebuilt after the fire, have modern single-lever and pull-down faucets that are usually simple to service. The city also keeps a service line inventory to confirm no customers are on lead lines, and asks owners with unknown materials to self-report.
Louisville's Building Safety Division performs plumbing inspections, and the plumber can tell you whether your job needs a permit. For water main problems outside the house, Public Works is at (303) 335-4608, with an after-hours on-call line at (303) 489-2301.
Before the plumber arrives

- Find the faucet's warranty paperwork if the home is newer
- Take a photo of the faucet and under-sink connections
- Write down when the leak started and what it does
- If you are in a rebuilt home, note the builder in case fixture warranties apply
