“Who is the best plumber in Great Falls, Montana?”

There's no single "best" plumber. It depends on what you need, like emergency repair, a water heater, or remodel plumbing. Here are two local companies with strong reviews on Angi:

• Polzin Plumbing LLC: One reviewer said "Brett and his guys have run gas lines, installed faucets, changed out water heaters, replaced outside spigots and plumbed washer dryer hookups for me. The work is always started in a timely frame, work was done properly. The best part for me is that they always leave the job site clean."
• 911 Plumbing & Heating: A customer who had a bathroom remodel wrote that "Derek at 911 Plumbing did an outstanding job. Him and his crew showed up on time and worked very efficiently." They also said the crew "got the plumbing back to code".

Before you hire:

• Compare recent reviews on Google, Yelp, Angi and the BBB.
• Check that the plumber is licensed with the Montana Department of Labor & Industry (they have an online license lookup).
• Get two or three written quotes, especially for big jobs.
• If you need emergency service, ask whether they're available 24/7.

If you tell me what kind of job it is, I can look for plumbers who do that kind of work.
