Montana Contractor Guide

Licensing in Montana

The average home improvement project in Montana runs about $35,000. That's close to the roughly $35,540 national average project cost. That puts it roughly in the middle nationally — 23rd highest of the 50 states. Montana has no statewide contractor license, so vetting falls entirely on you: check local city or county licensing (many require it even where the state doesn't), get references, and confirm insurance directly. The most common projects here are Insulation upgrade, Deck addition and Window replacement. Montana does not license general contractors statewide. Electricians and plumbers must be state-licensed.

How to Vet and Pay a Contractor Safely

Get at least three written bids for anything over a couple thousand dollars — a bid that's dramatically lower than the others is a red flag, not a deal. Never pay more than 10–30% upfront (many states cap deposits by law); the rest should follow a payment schedule tied to inspected milestones, with the final payment held until the work passes a final walkthrough. Confirm the contractor carries general liability and workers' comp insurance — ask for a certificate naming you, not just their word for it — and get every change order in writing before the work starts, not after. For structural, electrical, or plumbing work, confirm your contractor is pulling the required permits — unpermitted work can complicate a future sale and may not be covered by insurance if something goes wrong.
