How the call works

Your call goes to an independent plumber who serves Thornton. Expect questions about which fixtures are slow, whether anything has overflowed, and whether the problem started suddenly or built up over weeks. Those answers help the plumber decide what equipment to bring: a small cable for a sink, or a main line machine if the whole house is affected. On arrival, the plumber will usually look for a cleanout before pulling a toilet.

Cost factors

  • Which line is blocked: a branch line under one sink or the main that serves the house
  • Access, including whether a cleanout exists and can be opened
  • The tool required, from a hand auger to a jetter
  • Whether a camera inspection is needed to explain repeat clogs
  • Any repair found during the work, which is quoted separately
  • Visits outside normal weekday hours

What is different about Thornton

Thornton maintains its own wastewater lines, and the flow goes to Metro Water Recovery for treatment. If you suspect a problem in the public main, the city's Utilities Operations line is 720-977-6500. A plumber will confirm whether your service line runs clear before you make that call.

Most of the city is newer than the metro average: Census survey estimates put the median home at 1997, with about 22% built before 1980. The older stock sits mainly in the south end, where cast iron and older sewer pipe can come up. In the newer subdivisions toward E-470, plastic pipe is the norm, and clogs there usually trace back to grease, wipes and food waste rather than pipe failure.

Thornton's water is hard, averaging about 230 mg/L per the city's report. Hardness mostly affects water heaters and fixtures, though mineral scale can add to buildup in older metal drain lines.

Before the plumber arrives

  • Stop running water in the house if the main line is backing up
  • Clear a path to the cleanout, the water heater area and the lowest drain
  • Do not pour chemical drain opener into a standing clog
  • Move stored items away from basement floor drains
  • Note when the problem started and what was draining at the time

Drain Cleaning questions in Thornton

How can I tell if a clog is in my own line or in the public sewer main?
Check whether one fixture or the whole house is affected. A plumber can confirm your line is open to the property edge; if sewage still backs up, call Thornton Utilities Operations at 720-977-6500 about the public main.
Are chemical drain cleaners from the store a good idea?
They rarely clear a solid blockage and can sit in the pipe, which makes the plumber's work harder and riskier. Mechanical clearing is safer, especially in older metal drains.
Does running hot water help grease go down the kitchen drain?
No. Hot water carries grease a short distance before it cools and sticks. Wipe pans and put cooled grease in the trash.
Do I need a permit to have a drain cleared?
Clearing a clog is generally service work without a permit. If the job becomes a repair or replacement of plumbing, Thornton's Building Inspection Division lists plumbing modifications among work that needs one.
