NW Twin Cities Insulation Contractor & Concrete LevelingThe cold
stops here.
Foam-Tek is the insulation contractor sealing attics, walls, and garages across the northwest metro with spray foam. The same expanding polyurethane technology lifts sunken driveways and slabs back to level. One technology, two fixes, free estimates.
One material, two trades
Expanding polyurethane, put to work twice
The foam that seals your attic against a January wind is the same chemistry that lifts a sunken driveway back to grade. Most companies do one or the other. Foam-Tek built both trades on the same trucks, the same material science, and the same crews.
Division 01 · Primary
Insulation
Spray foam, blown-in, batts, and dense-pack. Attics, walls, garages, and rim joists sealed for Minnesota winters and sized to Minnesota energy rebates.

Insulation services
Sealed tight, floor to ridge
Every job starts with a free assessment of where your building actually loses energy. Then we spec the right material, not the one we happen to sell.
CLOSED-CELL · OPEN-CELL
Spray Foam Insulation
Our flagship service. Liquid polyurethane expands to fill every crack, gap, and rim joist, then cures into an air, moisture, and thermal barrier in one pass. The right answer for attics, garages, basements, and pole buildings that have to survive Minnesota winters.
Everything about spray foam →FOAM · BATTS · BLOWN-IN
Attic Insulation
Insulation and re-insulation for attics that leak heat all winter. We match the method to the attic: spray foam, fiberglass, or blown-in cellulose.

FIBERGLASS · CELLULOSE
Blown-In Insulation
Blown-in fill that levels evenly across attic cavities, closing the gaps batts leave behind and raising R-value without a teardown.

HIGH R-VALUE BATTS
Fiberglass Insulation
Batt installation for walls, floors, and new construction that meets modern code and keeps conditioned air where you paid to put it.

DENSE-PACK · LOOSE-FILL
Cellulose Insulation
Recycled-fiber insulation for attics and walls. Quiets road noise, slows heat loss, and installs clean in retrofit homes.

RETROFIT WALLS
Dense-Pack Insulation
Existing walls packed tight through small access points. Kills drafts in older homes without opening up the drywall.

SHOPS · FINISHED SPACES
Garage Insulation
Foam or fiberglass for garages that need to hold heat: workshops, gyms, and the third stall you actually work in.

Concrete services
Sunken concrete, raised in hours
We inject expanding polyurethane through dime-sized holes, fill the voids frost heave left behind, and lift the slab back to grade. No demolition, no truckloads of new concrete, no waiting a weekend to park on it. Drag the slider: this is a Foam-Tek driveway job.

How a job runs
Four steps, one visit
Most residential jobs, insulation or concrete, are done in a single day.
- Step 1 of 4
Assess
A free on-site look at where your building loses energy or where your slab has settled. You get straight answers and a firm number, not a sales pitch.
- Step 2 of 4
Prep
We mask, ventilate, and protect the work area. For concrete, that means marking utilities and drilling a handful of dime-sized holes.
- Step 3 of 4
Apply
Commercial rigs meter the foam to spec: precise thickness on walls and attics, controlled lift under slabs, checked against a level line as it rises.
- Step 4 of 4
Inspect
We verify coverage and cure, patch the injection holes, and haul out everything we brought in. Then we walk the job with you before we leave.
Our work
Real jobs, before and after
These are our own photos from work across the northwest metro. The thermal images are shot with our camera on site, which is how we find the heat loss before we ever open a wall.
The camera finds what the eye cannot: 35.3°F in this ceiling corner against 57.2°F beside it. That gap is the heat loss we seal.

Fair questions
Asked by every homeowner, answered straight
Foam holding up a driveway sounds wrong the first time you hear it. These are the questions we get on real driveways, with the answers we give there.
Foam? To hold up my concrete?+
Yes. Cured polyurethane is rigid, waterproof, and supports thousands of pounds per square foot. It weighs a fraction of the mudjacking slurry it replaced, so it lifts the slab without adding load to soil that already settled once.
Won't animals chew through it?+
Under a slab there is nothing for them to want: the foam is inert, has no food value, and there is no cavity to nest in. In walls and attics, foam actually closes the entry gaps that mice and insects use in the first place.
Won't my concrete just sink again with the next frost cycle?+
The foam fills the voids that water needed to do its frost-heave work, and it does not wash out or absorb water the way a sand base does. Pair a lift with seam sealing and you have taken away both the space and the moisture that caused the settling.
How much can insulation actually cut my bills?+
It depends on what we find in the assessment: how leaky the building is now, its size, and your fuel. That is why the assessment is free and specific. We measure, then give you a number for your house instead of a brochure claim.
Open-cell or closed-cell spray foam?+
Closed-cell is denser, waterproof, and adds structural rigidity, which makes it the workhorse for rim joists, basements, and exterior assemblies. Open-cell is more economical per inch and better at sound, a fit for interior walls and big attic spans. We spec whichever the assembly calls for.
