Our top 10 plumbing companies in Denver

Denver plumbing trouble tends to come from two directions. Winter cold snaps freeze hose bibs, sprinkler lines and pipes in exterior walls, and a burst line in a crawlspace or garage is a common January call. Underground, many older neighborhoods such as Park Hill, Washington Park, Highland and Berkeley still have clay or cast iron sewer lines that tree roots find their way into, and several reviews behind this list describe main drain backups and full sewer line replacements. In Denver the sewer line from the house to the city main is generally the owner's responsibility, so a camera inspection before buying an older home is money well spent. The other lesson from these reviews is to get a second opinion on big sewer quotes. One homeowner was told a collapsed line needed a repair of more than $5,500, and another company cleared a root blockage for $95. A camera inspection and a clear video of the problem should come before any excavation. Before you hire anyone, check the license. Colorado licenses master, journeyman and residential plumbers, and plumbing contractors must register with the State Plumbing Board, part of the Department of Regulatory Agencies. You can look up a license number on the state's DORA site. Water heater replacements, gas lines, sewer repairs and most plumbing alterations in Denver also need a permit from Denver Community Planning and Development, and the contractor should tell you who pulls it. Six of the ten companies here publish Colorado license numbers online, and for the others it is worth asking directly.

How we chose the best plumbing companies in Denver

Read our full ranking methodology →

We started from Google Maps searches for plumbers and plumbing companies in Denver and kept Google's order, adding two more searches because several top results were based outside the city. Each company had to be operating, based inside the City and County of Denver, rated 4.5 or higher with a meaningful review history, and running its own working website that matched its Google listing. We read each website for licenses, warranties, services and staff, and compared it with Google's address, phone and hours. We left out companies based in Adams County, Aurora, Englewood and other suburbs, one whose website was down, one whose site named two different founders and one listed in a shared office suite with several addresses. We also listed only one of two sister companies under the same ownership. Ratings and review counts were read on September 24, 2026. No company paid to be included or to be ranked higher.

How to choose a plumber in Denver

  • Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  • Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  • Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  • Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  • Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  • Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  • Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  • Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

  • Are you insured, and can you send the certificate?
  • How long have you worked in this area?
  • Will you provide a written estimate with materials listed?
  • What warranty do you offer on the work itself?
  • Do you use subcontractors for this job?
  • Who handles permits and inspection?
  • What would you recommend here, and why?
  • How are unexpected costs handled once work starts?
  • What is the estimated timeline from start to finish?
  • Can you provide recent local references?

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope

Plumbing companies in Denver FAQs

  • How do I check a plumber's license in Colorado?

    Look up the license number on the Colorado Department of Regulatory Agencies website. The State Plumbing Board licenses master, journeyman and residential plumbers and registers plumbing contractors. Six companies on this list publish their numbers online, including Applewood, Speed Plumbing, Mighty and Doctor Fix-It.

  • Which Denver plumbers are open 24 hours?

    Google lists A Better Plumber, Time Plumbing, Speed Plumbing, Squeaks, Golden West, Heart, Mighty and Doctor Fix-It as open 24 hours. Applewood runs 6am to 10pm daily with no overtime charge, and Blue Sky keeps weekday and Saturday office hours but says its emergency team is on call.

  • Who is responsible for a broken sewer line in Denver?

    In Denver the sewer line from the house to the city main is generally the property owner's responsibility. Ask for a camera inspection and video before agreeing to excavation, and get a second opinion on large quotes. A Better Plumber, Blue Sky and Doctor Fix-It all have strong reviews for sewer work.
