Increase Comfort and Energy Efficiency in Your Home and Basement with Spray Foam in the Rim Joist

Most homes in Michigan have insufficient or no insulation in their rim joist, causing cold outside air to enter the home around the foundation area easily.

Open cell spray foam expands 100 times to fill all the cracks and crevices in the rim joist. With a total air seal that other insulation materials can’t hold a stick to, spray foam in the rim joist is one of the most cost-efficient ways for homeowners to take control of the comfort and energy efficiency in their home and basement.

Updating a Rim Joist with Spray Foam Insulation is a Major Home Improvement for the Investment

Improving Your Home’s Performance Doesn’t Have to Be Difficult

The process of insulating a rim joist is quick and simple for homeowners who want to get started with comfort and energy-efficient updates or for the homeowner ready to retrofit the entire house with foam insulation.


If there is currently old fiberglass insulation in the rim joist, a crew will remove the old insulation and dispose of it, so you don’t have to mess with it. They will then ensure any furniture or storage bins are cleared away from the basement walls. If necessary, the crew will then place plastic over the windows and any shelves and storage to ensure they don’t get overspray on them.

If we are also insulating your crawl space, the rim joist is included in that scope of work as well.

"Had the roof deck in my attic and rim joists done on my house by Bill and his crew. From start to finish these guys were nothing but the best/friendliest/most professional company out there. I was sold from the minute I got my initial estimate, and ultimately, in the end, everything was delivered as promised. Not sure what these guys are making, but whatever they are, they deserve a raise because they 100% deserve it."
