Insulation slows heat; air sealing stops it - gaps around pipes, outlets, and framing are often the biggest source of heat loss in older homes.
Learn MoreReach out by phone or through our contact form. We ask a few basic questions about your home - its age, the areas you want insulated, and any problems you have noticed, like high heating bills or cold rooms. No technical knowledge required. We respond within 1 business day.
We visit your home, measure the areas to be insulated, check for existing issues like moisture or damaged material, and identify where air is escaping. You get a written estimate that spells out exactly what is included and why - before any work is agreed to. No obligation.
On the scheduled day, our crew handles everything: prep, installation, and cleanup. For most homes, the work is done in a single day. When we finish, we walk you through the completed work so you can see what was done and ask any questions before we leave.
We carry full liability insurance and workers compensation on every project. Before work starts, we can hand you proof of current coverage - so you are protected if anything unexpected happens on your property.
Every quote starts with an in-person visit - we measure the space, check for air leaks, and explain exactly what the job involves. You get a written estimate before we touch anything. No surprise charges, no pressure.
We are a Minot-based company. We know the local climate, the age of the housing stock, and what it takes to keep a North Dakota home warm when January temperatures drop below zero. You get someone who already understands your situation.
You get a written estimate before work starts and a full walkthrough when the job is done. We show you what was installed, where, and at what depth - so you always have documentation for your records, tax credits, or a future home sale.

We had ice dams on the roof every single winter for years. After they insulated and sealed the attic, we went through the whole season without one. The difference showed up on our heating bill too - noticeably lower than the year before.
Mark T., Minot - Attic Insulation
The spray foam crew finished the crawl space in one day, which I did not expect for a job that size. The floors above it used to be cold no matter what we did. Now they hold heat the way the rest of the house does. Happy with the result.
Diane K., Bismarck - Spray Foam Insulation
I called after noticing our gas bill was way higher than our neighbors with a similar house. They came out, found the attic was way under-insulated for North Dakota winters, and had the blown-in installed within the week. Straightforward process.

Rising bills with no change in habits almost always point to heat escaping through gaps in your building envelope. The most common culprits are an underinsulated attic, unsealed rim joists, or deteriorating crawl space insulation. The U.S. Department of Energy estimates that air sealing and insulation together can cut total energy costs by up to 15 percent annually.
Wind-driven infiltration pushes cold air through gaps with more force than still-air convection. In Minot's consistently windy climate, even small cracks around outlets, pipe penetrations, or attic hatches let in far more cold air during a north wind than a national average would suggest. That is why air sealing is not optional here - it is the foundation of any insulation upgrade. The DOE covers this at energy.gov/energysaver/air-sealing-your-home.U.S. Department of Energy - Air Sealing
Ice dams form when heat escaping through your attic warms the roof deck and melts snow, which then refreezes at the cold eaves. The water backed up behind that ice can force its way under shingles and into your home. Adding attic insulation and sealing the gaps where warm air rises from your living space removes the root cause - not just the symptom.
Blown-in insulation covers large attic floors quickly and cost-effectively. Spray foam is the right choice when you need to seal an area while insulating it at the same time - rim joists, crawl space walls, and tight attic cavities are the most common applications. Closed-cell spray foam also acts as a moisture barrier, which matters in a region with significant freeze-thaw cycling.
Most likely, yes. Homes built in Minot before 1990 were insulated to standards far below what is recommended today for Climate Zone 7 - one of the coldest designations in the country. Many of these homes have original insulation that has settled or degraded over decades. A quick attic check - if the floor joists are visible, you are likely under-insulated - tells the story clearly.
Yes. The Inflation Reduction Act created a tax credit covering up to 30 percent of qualifying insulation project costs, capped at $1,200 per year for existing homes. Your contractor should confirm which materials qualify and provide documentation at tax time. North Dakota utility programs through MDU Resources have also offered rebates for energy efficiency improvements. More information is available at the ENERGY STAR federal tax credits page.

Homes built before modern energy codes in North Dakota were insulated to standards far below what is recommended today. If you have never had an insulation upgrade, a current assessment will almost always find room for improvement.
In almost every case, yes. Ice dams form because heat is escaping through your attic. The North American Insulation Manufacturers Association covers this in detail at naima.org - and the fix is typically attic insulation combined with air sealing, not roof repairs. Read more at NAIMA
Tell your contractor before the job starts that you want to apply for the federal energy efficiency tax credit. They need to confirm the materials qualify and provide manufacturer documentation. The credit is worth up to 30 percent of project cost, capped at $1,200 per year.

Minot is North Dakota's fourth-largest city, with roughly 48,000 to 50,000 residents and a regional hub for shopping, medical care, and services across north-central North Dakota. The city earned the nickname "Magic City" after growing almost overnight following the arrival of the Great Northern Railway in 1886. Its neighborhoods range from older downtown blocks where most homes date from the 1940s through 1970s, to newer subdivisions on the city's south side.
A large share of Minot's housing stock consists of ranch-style and two-story wood-frame homes built in the postwar era - homes that are now 50 to 80 years old and often under-insulated by current standards. The area around Roosevelt Park and the neighborhoods near the Souris River include many homes rebuilt or renovated after the historic 2011 flood that damaged more than 4,000 homes. The city also has a strong presence from Minot Air Force Base, just north of the city, which brings a rotating population of military families who often need help quickly understanding what their home needs for this climate.
Minot's winters are among the harshest in the continental United States, with average January lows well below zero and frost that penetrates 5 to 6 feet into the ground. That combination of extreme cold, older housing stock, and a history of flood damage makes insulation one of the highest-return improvements a Minot homeowner can make - and it is exactly the kind of work Minot Insulation does every day.
