Hiring a Licensed Plumber in Montana

Who licenses plumbers

The Montana Board of Plumbers, part of the state Department of Labor and Industry, oversees plumbing licenses. The state issues journeyman licenses, for plumbers working under supervision, and master licenses, for plumbers who can run jobs and supervise others.

Check the license

Ask for the plumber's license number and look it up with the state's online license search. Make sure it's active and matches the name of the person or business you're hiring.

Permits

Larger jobs, such as water heater replacements, gas lines and new plumbing, usually need a permit and inspection. Ask who will arrange it.

Get quotes in writing

For bigger jobs, get a written quote that lists the work, materials, permit and clean-up. Compare quotes by what's included, not only the price.

Questions to ask

How long will the water be off? Is there a warranty on parts and labor? Who do I contact if something goes wrong afterward?

Ready to go

Red flags

Be wary of anyone who asks for full payment up front, won't share a license number, or suggests skipping the permit to save money. A licensed plumber should be comfortable explaining the inspection and putting the scope of the job in writing before starting.

Keep the paperwork

Keep the invoice, permit and any warranty documents with your home records. Note the brand and model of anything installed. If a problem shows up later, those details help the plumber who did the work, or a new one, sort it out quickly.
