Insulation Services in Bozeman, MT
Since opening in Bozeman in 2018, Cullen Insulation has been proud to serve a community that values hard work, craftsmanship, and neighborly service. Our company was founded in Fargo, North Dakota, in 1988 by Terry Cullen, and those roots still shape how we do business today. Led by our president Dan Frisch and VP Eric Brutger, we continue to bring that same level of excellence to Big Sky Country and our Bozeman friends and neighbors. We work with homeowners, builders, and property managers across the Bozeman area with a strong focus on relationships, communication, and doing the job right.
Bozeman is a unique place to live and build. Set at about 4,800 feet high in the Gallatin Valley, this area sees harsh winters, heavy snowfall, and wide temperature swings from day to night. That mountain climate can put real demands on homes and buildings. Insulation plays an important role, especially in attics and crawl spaces, in controlling heat loss, managing moisture, and helping prevent issues like ice damming.
As Bozeman continues to grow, local homes and buildings need to perform well in every season. Whether you are near Montana State University, building for a growing neighborhood, or working on a property connected to the greater Yellowstone or Big Sky area, Cullen Insulation is here to help you create a more comfortable and efficient space.
As a trusted insulation contractor Bozeman property owners rely on, we understand that every project is different. Our team takes the time to understand your goals and recommend the right solution for your structure and your climate.

Insulation Services We Provide to Our Bozeman Community
In this region, attics and crawl spaces deserve special attention. Heat loss through an under-insulated attic can lead to uneven indoor temperatures, higher heating bills, and ice damming when rooftop snow melts and refreezes. Crawl spaces can also create comfort and moisture issues when they are not properly insulated and sealed. By addressing these areas and reducing unwanted air movement throughout your home or building, we help customers create spaces that feel better year-round.
For many properties, that starts with tightening up the building envelope. Air sealing Bozeman homes and buildings is one of the most effective ways to reduce drafts and prevent conditioned air from escaping. When outside air gets in and indoor air leaks out, insulation cannot perform as well as it should. Sealing those gaps helps improve comfort and supports better energy performance.
We also provide spray foam insulation Bozeman property owners often choose for areas where insulation and air control need to work together. In the right applications, spray foam can help reduce air movement while supporting strong thermal performance.
For projects that call for a dependable, cost-effective insulation system, we install fiberglass insulation Bozeman, MT homeowners, builders, and contractors continue to trust. Fiberglass remains a strong option for many residential and commercial applications and can be an effective choice for walls, ceilings, and other insulated areas.
As an insulation company Bozeman, MT residents know and recommend, Cullen Insulation works with homeowners, builders, multifamily contractors, and commercial clients throughout the region. No matter the size of your project, we stay focused on communication, dependable service, and work done with care.

Installing Excellence for our Bozeman Community
We love being part of the Bozeman community and the things that make it special. From the pride of the MSU Bobcats community to the steady flow of residents and visitors drawn by Yellowstone, Big Sky, and life in the Gallatin Valley, Bozeman continues to grow while holding onto its strong sense of place. That local character matters, and we are proud to serve it.
Cullen Insulation may have started in Fargo in 1988, but our approach has always been centered on relationships, respect, and doing right by the people we serve. Since coming to Bozeman in 2018, we have been grateful for the opportunity to work with local homeowners, builders, and property managers who care deeply about their properties and community.
In a climate like this one, insulation is an important part of comfort, efficiency, and long-term building performance. Harsh winters, snowfall, and mountain weather can expose weak points in a structure quickly. The right insulation and air sealing plan helps protect against those issues while supporting better comfort in every season.
