When a pipe bursts in a Louisville home, close the main shutoff and switch off power to anything wet. A plumber can cut out the failed pipe, splice in new and check nearby lines. Call the number on this page to be connected with a local plumber in Louisville.

Once you make the call
You'll be connected with an independent plumber who covers Louisville. Explain where the water is coming from, whether you closed the main and what kind of pipe you see. On site, the plumber confirms the shutoff, opens the smallest practical access, removes the damaged pipe and installs a new section. Then the water goes back on slowly while the repair and the nearby joints are watched for drips.
Cost drivers
- Where the break is, and how much finished surface has to come out
- Pipe material, and whether old and new types meet
- More than one crack along a frozen run
- Buried line work between the meter and the house
- Inspection by the city's Building Safety Division when a permit applies
- Calls on nights, weekends or holidays
Louisville conditions
Louisville is a former coal-mining town in southeastern Boulder County, with a historic downtown around Main Street and neighborhoods spreading out toward US-36. Older houses near downtown have often been replumbed in stages, while hundreds of homes rebuilt after the December 2021 Marshall Fire have new plumbing throughout. In either case, the freeze risk sits in lines along exterior walls, in garages and in crawl spaces.
The City of Louisville runs its own water and sewer utility with two water treatment plants, and few homes rely on private wells. For a break on the city's side, or help after hours, Public Works is at (303) 335-4608 and the Operations Division on-call line is (303) 489-2301 after 3:30 p.m. The city keeps a service line inventory to confirm no customers are served by lead lines, and asks owners who don't know their line's material to report it; a repair that exposes the yard line is a good chance to find out.
Louisville's Building Safety Division (303-335-4584, City Hall at 749 Main Street) performs plumbing inspections. Ask the plumber whether your repair needs a permit before the work begins.
Short checklist
- Main closed and a low faucet open
- Power off to wet outlets and appliances
- Water heater off or on pilot
- Photos of the damage before you mop
- Path cleared to the main valve and the leak
