Plumber in Denver: an independent guide to costs, permits and hiring

What do common plumbing jobs cost in Denver?

No public agency publishes Denver-only plumbing prices, so the table below uses national ranges from established cost guides. Use it to judge whether a written quote is in a normal range, not as a price anyone has promised you. Access, pipe material, the age of the home and permit fees can all move a real quote up or down.

Nights, weekends and holidays cost more. Angi's September 2026 guide says emergency plumbers typically charge 1.5 to 3 times their normal rate. For a longer breakdown by job, see our Denver plumber cost guide.

Which plumbing warning signs matter most in Denver?

Some problems can wait for a weekday estimate. Others get more expensive by the hour. These are the ones worth acting on quickly:

• Water spreading from a pipe, fitting or tank. Close the main shutoff first. Denver Water says that in most single-family homes the valve is in the basement or crawl space, on a wall facing the street.
• A gas smell near a water heater, boiler or range. Leave the building. Xcel Energy tells customers who suspect a leak to get out and call 800-895-2999 or 911.
• Several drains backing up at once, especially a basement floor drain. That usually points to the main line or the sewer lateral rather than a single fixture.
• Sewer odor without a backup. Denver's Wastewater Management Division notes that a dry drain trap can let sewer gas into the house. Running water into seldom-used drains once a month restores the seal.
• An aging tank water heater that leaks, rumbles or delivers rusty water. HomeGuide puts typical tank lifespans at 8 to 12 years.
• Exposed pipes during a cold snap, in exterior walls, crawl spaces or an attached garage.

If something is happening right now, our emergency checklist covers shutoff valves, gas, frozen pipes and sewer backups, with the official numbers to call.

How do you hire a licensed plumber in 5 steps?

1. Write down the problem. Note what you see, where, since when, and the age and type of the equipment. Photos of the pipe, the data plate on a water heater or boiler, and any water damage make quotes more accurate.
2. Check the license. Colorado's State Plumbing Board, part of the Division of Professions and Occupations, licenses individual plumbers at residential, journeyworker and master levels and requires continuing education every license year. Search the person's name in the DORA license lookup. Inside the City and County of Denver, the business also needs a Denver contractor license, and Denver does not accept licenses issued by other counties or states.
3. Get more than one written estimate. The FTC says an estimate should describe the work to be done, and warns against hiring the lowest bid without asking why bids differ.
4. Ask who pulls the permit. Denver lists water heaters, water service lines, water softeners and fixtures among single-family plumbing work that qualifies for a quick permit. The FTC lists a contractor who asks you to get the permits yourself as a red flag.
5. Pay in stages. Do not pay the full price up front, and hold the final payment until the work is finished and you are satisfied with it.

Our plumbing services overview explains water heaters, drain cleaning, sewer lines, boilers and emergency work, each with cost ranges, permit notes and questions to ask. The service area pages cover Aurora, Lakewood, Arvada, Westminster, Thornton, Centennial, Littleton and Parker and explain how permits and utilities can differ outside Denver city limits. The homeowner guides go deeper on frozen pipes, expansive soil and slab leaks, boiler maintenance and choosing a plumber.

One Denver-specific item worth knowing: Denver Water estimates that 60,000 to 64,000 homes in its service area may have a lead service line, and its online address search shows whether yours is one of them. It also offers free water test kits.
