Mandan Insulation serves Glen Ullin, ND as an insulation contractor for older single-family homes throughout Morton County, providing home insulation, spray foam insulation, attic upgrades, and basement wall insulation for houses built before 1960 that need real thermal improvements - not patches. We respond within one business day and give you a written quote before any work starts.
Glen Ullin homes built before 1960 are the dominant housing type in this community, and most were insulated to standards that fall well short of what Climate Zone 6 requires today. Our home insulation work covers the full envelope - attic, rim joists, basement walls, and crawl spaces - addressing each area in the order that delivers the most benefit for a home in this climate.
Older Glen Ullin homes commonly have uninsulated rim joists and sill plates where the floor system meets the foundation wall - a gap that allows outside air to enter directly under the living space floor. Spray foam applied to the rim joist seals air infiltration and adds R-value simultaneously, making it the single most impactful upgrade available for homes of this age in this climate.
Most attics in Glen Ullin homes built before 1970 are well below the R-49 to R-60 level recommended for Climate Zone 6. With January temperatures that can drop below minus 20 degrees Fahrenheit and a heating season that runs from October through April, the attic is where inadequate insulation has the largest effect on monthly heating costs - and where additional coverage delivers the most consistent return.
Glen Ullin sits in Morton County where frost depth commonly reaches 4 feet in winter, which means the soil surrounding every basement wall in town is frozen solid for months. Uninsulated concrete walls transfer that cold directly into the floor system above, making first-floor rooms uncomfortable throughout the heating season. Interior basement wall insulation - spray foam, rigid board, or framed batts - makes a real difference in how warm the house feels from the ground up.
In Glen Ullin homes built before the 1980s, air leaks at attic hatches, partition top plates, and around electrical and plumbing penetrations allow warm interior air to escape into the cold attic all winter. Sealing these bypasses before adding blown-in insulation is not optional in this climate - without it, insulation alone cannot perform as rated because air continues moving through and around it.
For Glen Ullin homeowners whose attics already have some insulation but need more, blown-in cellulose or fiberglass installs over existing material in a single visit without any demolition. It fills around pipe and duct penetrations and brings coverage to recommended levels efficiently - and on a home that has been standing since the railroad era, it is often the most practical way to make a meaningful improvement to heating costs this season.
Glen Ullin is a small Morton County community of roughly 750 to 800 residents, situated along Interstate 94 about 60 miles west of Bismarck near the Heart River. The town was founded as a Northern Pacific Railroad stop in the late 1800s, and most of its residential housing reflects that era - wood-frame construction on standard town lots, many of the homes built between 1900 and 1960, with older plaster walls, original wood windows, and foundations that have endured generations of freeze-thaw cycles. These homes were built solidly for their time, but the insulation installed in the early to mid-1900s degrades, settles, and falls far short of the R-49 to R-60 attic levels that Climate Zone 6 recommends today. The heating season in Glen Ullin runs from October through April, and January lows can drop below minus 20 degrees Fahrenheit - conditions that expose every weakness in an under-insulated envelope.
The frost depth in Morton County reaches 4 feet or more in a typical winter, and the spring thaw brings its own problems. Clay soils around Glen Ullin drain slowly, so hydrostatic pressure builds against basement walls in March and April when the snowmelt has nowhere to go. Homes with uninsulated or cracked basement walls face moisture intrusion at exactly the same point they are most vulnerable from months of thermal stress. An insulation contractor serving Glen Ullin needs to think about moisture management alongside thermal performance - closed-cell spray foam on rim joists and basement wall surfaces addresses both at once, which is why it is our first recommendation for older homes in this community.
Our crew works throughout Glen Ullin regularly, and we understand the local conditions that affect insulation work here. The homes we see most often in Glen Ullin are older wood-frame structures from the railroad and early farming era - homes that have been re-sided once or twice over the decades, often with aluminum or vinyl installed over original wood lap siding. Underneath that re-siding, it is common to find deteriorated sheathing or wall cavities with little or no insulation still in place. We plan for this when scoping rim joist and basement work, because what looks like a clean exterior does not always indicate what is behind it.
Glen Ullin sits along I-94 in Morton County, near the Heart River. The community is close to the original Northern Pacific Railroad corridor that shaped this part of North Dakota's development. The Morton County seat is in Mandan, where county permits and records are handled for the broader region. For building questions specific to the community, the Morton County government is the right contact for permit guidance.
We serve neighboring communities along the I-94 corridor including Hebron, ND to the west and Mandan, ND to the east - all Morton County communities where older housing stock creates similar insulation challenges.
Call or submit a request online and we will follow up within one business day. We will ask a few questions about your home and what you have been noticing - high heating bills, drafts, cold floors - so we can plan the site assessment efficiently.
We visit your Glen Ullin home to inspect the attic, rim joists, basement walls, and any crawl spaces. We measure actual installed R-values and check for air leak locations. You receive a written quote with line-item costs before any commitment - no pressure, no vague estimates, and no surprise charges added later.
Most residential insulation jobs in Glen Ullin are finished in a single day. For spray foam applications, the treated area needs to be clear during application and for a short cure period. For blown-in attic work, you can remain in the home. We go over all of this during scheduling so nothing is a surprise on installation day.
When the job is done, we walk through the completed work with you, explain what was done and why, and answer any questions. If anything comes up after we leave, you can reach us by phone. We do not consider the job finished until you are satisfied with what was done.

(701) 291-0855Glen Ullin is a small Morton County city of roughly 750 to 800 residents, located along Interstate 94 near the Heart River in southwestern North Dakota. The town was founded in the 1880s as a stop on the Northern Pacific Railroad, and farming has been the backbone of the local economy ever since. The character of the community is entirely residential and agricultural - single-family homes on standard town lots, many with a detached garage or outbuilding on the property. Because the town developed early and grew slowly, most of its housing stock dates to the 1900 to 1960 era. These are older wood-frame homes that have been through many cycles of renovation and re-siding, and they reflect the kind of practical, built-to-last construction common in small North Dakota railroad towns. For more on the town's history, the Glen Ullin Wikipedia entry provides a good overview of its railroad and agricultural roots.
The surrounding landscape is rolling prairie and farmland, with the Heart River running nearby. Properties on the outer edges of town are often larger lots with outbuildings or small agricultural structures that need the same winter weatherization attention as the main house. Glen Ullin's Morton County location connects it to neighboring communities that face similar housing and climate challenges - including Hebron, ND to the west and New Salem, ND to the east along the I-94 corridor.
