In Louisville, hydro jetting means sending a high-pressure water nozzle through a home's sewer line to cut roots and wash out grease and sludge, leaving the pipe wall clean instead of just poking a hole through the clog. It's the usual step when snaking hasn't held. Call the number on this page to be connected with a local plumber in Louisville.

What happens when you call
The number on this page connects you with an independent plumber who works in Louisville. Say which drains are acting up, whether it's the lowest drains in the house, and whether the line has been cleaned before. If you've already called the city and it found its main clear, mention that too.
At the house, the plumber opens a cleanout, often runs a camera to see the cause, and jets from the house toward the main. The nozzle scrubs the full circle of the pipe and flushes debris downstream. A second camera pass shows whether the line is clear or damaged.
Cost factors
- Cleanout access versus working through a toilet or vent
- Length and depth of the line
- Roots or scale in older pipe versus grease in newer pipe
- Camera inspection
- After-hours timing
Louisville conditions
Louisville is a former coal-mining town turned suburban community in southeastern Boulder County, with a historic downtown along Main Street. It's a city of contrasts underground: older homes near downtown can have cast iron and clay drain lines with roots and scale, while hundreds of homes rebuilt after the December 2021 Marshall Fire have brand-new plastic lines. A camera look tells the plumber which situation applies and how hard to run the jet.
The City of Louisville's Public Works Department runs the sewer and treats wastewater at the city-owned plant on the east side of town, built in 2017. For a sewer backup, the city's Operations Division takes calls at (303) 335-4750 on weekdays from 7 a.m. to 3:30 p.m., and its on-call line is (303) 489-2301 after hours. If the city finds its main is clear, the problem is in the private line between your house and the main.
Louisville's Building Safety Division performs plumbing inspections, so a repair found during cleaning goes through that office (303-335-4584).
Before the plumber arrives
- Call the city first if neighbors are backing up too
- Stop running water in the house
- Find and clear access to the cleanout
- Skip chemical drain cleaners
If your home was rebuilt after the fire, mention it when you call. A new line that clogs early sometimes has construction debris or a poorly sloped section, and a camera look sorts that out quickly.
