Rim Joist Insulation in the Twin Cities

If your home was built before the late 1990s, there is a good chance your rim joist was never insulated. Minnesota code did not require it back then, so in thousands of Twin Cities homes the only thing between your floor framing and a January night is a bare 2×10 or 2×12.

Cold conducts straight through that bare wood, and outside air leaks in as your foundation settles and cracks. That is why your floors feel cold and your basement feels drafty all winter. We spray foam the entire rim joist cavity, sealing and insulating it in one application, so the air movement stops and the floors above warm up.

Rim joist sealing is one of the most effective upgrades an older Minnesota home can get, and it can help your project qualify for local energy rebates. As an official Trades Partner, we diagnose exactly what your home needs and handle 100% of the utility rebate paperwork for you, so you don’t have to lift a finger to get your cash back.

Our Rim Joist Insulation Services

Closed-cell spray foam is the right material for rim joists, sealing air leaks, insulating, and resisting moisture in a single application. At Spray Foam Insulation Plus, our certified technicians spray foam rim joists in basements and crawl spaces across the Twin Cities, as a standalone project or as part of a larger basement insulation job, with results you can count on.


Why Choose Rim Joist Insulation?

  • Keep Mice Outside: Mice find their way in by feeling warm air escape through cracks near the rim joist, right at ground level. Sealing it removes the heat trail and the entry points.
  • Warmer Floors Upstairs: Cold conducts through an uninsulated rim joist and chills the floors above it. Sealing the rim warms the rooms over your basement.
  • Stop Basement Drafts: Much of the draftiness in an older home enters around the rim joist and sill plate. Spray foam closes those leaks for good.
  • Control Moisture: Closed-cell foam insulates and acts as a vapor barrier in one step, keeping condensation from collecting on cold wood in the rim cavity.
  • Seal Hidden Air Leaks: We close off the cracks and gaps around the rim joist and foundation that pull cold air into your home as the house settles.

Rim Joist Insulation FAQ

The rim joist, sometimes called a band joist, is the framing that runs around the perimeter of your home where the floor structure meets the foundation. In most homes built before the late 1990s it was never insulated, which makes it one of the leakiest spots in the whole house: cold air, moisture, and pests all find their way in there.

Fiberglass stuffed into a rim joist lets warm indoor air reach the cold wood behind it, where moisture condenses and can lead to mold and rot. Closed-cell spray foam seals the cavity, insulates, and acts as a vapor barrier in one application. It is the reason building code began requiring spray foamed rim joists in new homes in the late 1990s.

Yes. Mice are nearly blind and find openings by feeling the warm air that escapes through cracks near the foundation, right where the rim joist sits. When spray foam stops that air movement, the heat trail disappears and the gaps they squeeze through are sealed shut.

Most rim joist projects are completed in a few hours. We can spray foam the full perimeter of a typical basement in a single visit, and many customers combine it with attic or basement insulation work on the same day.

We only need access to the rim joist itself, the band of framing at the top of your foundation walls. Pulling stored items a few feet away from the perimeter is usually all it takes. We protect everything nearby and leave the space cleaner than when we came.

Prices follow material costs, so a number published today could be wrong next month. Call and you will talk directly to Travis, the owner. He can usually share current ballpark and per-square-foot ranges over the phone, then give you a firm quote after seeing your home.
