Built Fast, Settling Now
St. Michael turned from a farm town into one of the northwest metro's main family suburbs in about twenty-five years. Subdivisions arrived in waves: a big push in the mid-90s, another through the early 2000s, and a new round of construction in the 2020s around Town Center and the city's remaining open land. The STMA school district keeps pulling young families up I-94, and the housing stock shows it, with block after block of two-story homes, split entries, and townhomes built between 1995 and 2010. That 1995 to 2010 window is our sweet spot for insulation work. Those houses were framed tight enough to trap moisture but insulated only to the code of their day, which means attics at half of today's required R-value, bonus rooms over garages with air pouring through the floor system, and rim joists stuffed with fiberglass that does nothing to stop airflow. Ice dams are the winter tell. A ridge of ice at the gutter line almost always traces back to attic air leaks, and we fix the cause rather than chipping at the symptom. Underfoot, St. Michael deals with the same physics as the rest of Wright County: frost that drives several feet down, a spring melt that saturates the backfill around every foundation, and concrete that moves because of it. Driveways poured during the 90s boom are now twenty-five to thirty years into settling, and the aprons, stoops, and sidewalks show it. From our Monticello shop the drive is about twelve minutes, so our crews are in town constantly, often on both insulation and leveling jobs in the same week.

Two Crews, One Trip Down I-94
Our insulation crew works St. Michael attics, bonus rooms, rim joists, and basements with open-cell and closed-cell spray foam, and we bring attic insulation up to current code where the framing allows. Townhomes get the same attention as single-family homes; an end unit with one cold wall is one of the more common calls we take from this part of the corridor. For homeowners with detached shops or garages, closed-cell foam turns an unheatable shell into a building you can work in through January. The concrete leveling side lifts settled garage aprons, driveways, front stoops, patios, and sidewalk panels with structural polyurethane foam. The process uses dime-sized injection ports instead of the large holes mudjacking requires, the material cures in about fifteen minutes, and lifted slabs go back into service the same day. We also fill voids under slabs before they settle, which costs far less than lifting after the fact.
- Spray FoamClosed-cell and open-cell foam that seals air leaks and insulates in a single pass.
- AtticNew insulation and top-ups that stop heat loss through the biggest escape route in the house.
- Concrete LevelingPolyurethane foam injection that lifts sunken driveways, sidewalks, and floor slabs back to grade, usable the same day.
- Driveway LevelingSettled driveway slabs and garage aprons raised back to grade, drivable again the same day.
Spray foam, our specialty
Attic spray foam and air sealing is the job we do most in St. Michael, because the city's 90s and 2000s two-stories are exactly the housing that benefits. It is the flagship service of our insulation division, and ice dam calls from St. Michael keep it busy every winter.
Spray foam insulation in Minnesota →St. Michael questions
What causes ice dams on St. Michael homes, and can insulation fix them?+
Warm indoor air leaks into the attic, melts the underside of the snowpack, and the meltwater refreezes at the cold eaves. Insulation alone rarely fixes it; the air leaks have to be sealed first. We air-seal the attic floor, then insulate to current code, which stops the cycle at its source.
My bonus room over the garage is always cold. What is the fix?+
That floor hangs over unconditioned garage space, and builders typically filled it loosely with fiberglass. Spray foam applied to the garage ceiling cavity air-seals and insulates in one step. Paired with sealing the knee walls and rim area, it usually brings the room within a couple degrees of the rest of the house.
Is polyurethane leveling strong enough for my driveway?+
Yes. The structural foam we inject expands to fill voids and supports loads well beyond what a residential slab requires. It also weighs a fraction of mudjacking slurry, so it adds almost nothing to soil that is already settling. Driveways, garage aprons, and even street panels are routine lifts for it.
