How to Choose a Plumber in Boise, ID
Five checks before you hire any plumber in Boise: the Idaho license, the insurance certificate, how the price is built, the scope in writing, and who pulls the City permit. For scale, national guides put a plumber at $45–$150 an hour (read November 6, 2026) and the City of Boise's permit for a single fixture at $55. This page ranks no one and lists no ratings.

The five checks
- Idaho license. Ask for the plumbing contractor certificate number and look it up with DOPL. The record should be a contractor credential, active, unexpired, and under the same name as the quote. Step by step.
- Insurance. Ask for the certificate of liability insurance and call the agent named on it to confirm it is current. A license is not proof of insurance.
- How the price is built. Hourly plus a trip fee, or a flat rate? Is a diagnostic fee credited if you approve the repair? What is the after-hours charge? National guides put after-hours rates at $125–$170 an hour against $45–$150 in regular hours.
- Scope in writing. What is being replaced, with what, and what happens if the job grows once a wall or floor is open.
- The permit. Inside Boise, replacing a water heater, re-piping and adding fixtures all need a City plumbing permit. The contractor pulls it and books the inspection; it should be a line on the quote. What needs a permit.
Red flags
- No certificate number on the truck, the website or the quote, and reluctance to give one. Idaho's plumbing rules, as published, expect the number in a contractor's advertising.
- Asking you to pull the permit for work they are doing.
- A price that only exists verbally, or a large cash deposit before anything is written down.
- Pressure to replace a whole line or a whole system without showing you camera footage or the failed part.
- A name on the invoice that does not match the name on the license record.
Match the plumber to the job
- Drain and sewer work wants a company with its own cable machine, jetter and camera. Drain cleaning.
- Water heaters want someone who checks the gas line, venting, pan and expansion tank against the City's inspection list. Water heaters.
- Hidden leaks want detection equipment before any cutting. Leak detection.
Why no company list
Boise Elite Plumber is a referral service, not a plumbing company, and this page is not a ranking. We name companies only when we can describe each one from its own published information, and we have not done that work for Boise yet. Until we have, a list here would be guesswork, so there is none.
