Blown-In Insulation in Royalton, MN
Blown-in fiberglass and cellulose for attics and walls.
The Workhorse for Minnesota Attics
Blown-in fiberglass and cellulose are the most economical way to bring an open, vented attic floor up to a real Minnesota depth. The material fills between and over the joists, covers odd framing without gaps, and a typical attic takes a morning.
A proper blown-in job starts before the hose does: we check the roof deck and ventilation, cover recessed lights that need covers, baffle the eaves so the new depth does not choke airflow, and air-seal the ceiling penetrations that feed ice dams. Then we blow to a measured depth. You get the number in inches and R-value, not a vague promise of "more".
Blown-in also fills closed wall cavities in older homes through small access holes - a practical upgrade for older housing stock around St Cloud and Little Falls where the walls were built empty.

Common Questions
How many inches of blown-in insulation does a Minnesota attic need?
Minnesota attics are typically brought to roughly R-49 or better, which lands around 14 to 18 inches depending on the material. We measure to a stated depth and give you the inches and R-value in writing, not a vague 'top-up'.
Can you blow insulation on top of my existing attic insulation?
Yes, if the existing material is dry, clean and not rodent-damaged. If it is wet, mouldy or contaminated it has to come out first; burying a problem under new material only hides it.
Is blown-in fiberglass or cellulose better?
Both perform well installed properly. Cellulose is denser and fills tight spots well; fiberglass does not absorb water and weighs less on old framing. We recommend based on your attic rather than defaulting to one.
