About Northstar
A Missoula-based building group dedicated to honest work, clear communication, and craftsmanship that lasts.
Our Story
Built by hand.
Run by a local.
Northstar Building Group, LLC was founded by Mike Streit on a straightforward idea — that the best contractors are the ones you can call directly, who show up when they say they will, and who treat your property like their own.
From a single tree removal to a full commercial steel build, every project we take on gets the same standard of care. We’re a versatile crew, but we’re never spread thin. Quality first. Always.
Based in Missoula and serving Western Montana, we’re proud to be locally owned, locally accountable, and locally invested in the communities we work in.
- Locally owned & operated
- Free written estimates
- Residential & commercial
- Licensed & insured
What We Stand For
Four values. Every job.
These aren’t slogans on a truck. They’re how we run every project we touch.
Honesty
We say what we mean and mean what we say. Quotes are clear, timelines are realistic.
Integrity
We do the right thing — even when no one is watching. Especially then.
Communication
You’ll never wonder where your project stands. We pick up the phone.
Detail
The little things separate good work from great work. We obsess over them.
Rooted in Missoula.
We live here. Our kids go to school here. Our reputation walks the same streets you do. That’s why
we treat every project — small or large — like our name depends on it. Because it does.
