Closed-cell foam insulation in Apple Valley MN - more insulation in every inch
Cold floors over the garage, a drafty attic or a chilly basement wall? Dense foam sprayed in place seals air out and holds heat in.
Is closed-cell foam worth it for my Apple Valley home?
Closed-cell foam insulation is a dense foam, sprayed in place, that fills gaps, stops drafts and blocks moisture while it insulates, and in Apple Valley we use it most on basement walls, rooms over the garage and tight spots where every inch counts. It gives about twice the energy efficiency per inch of open-cell foam, and it keeps curing for a while after it goes on, so you'll plan some time out of the house.
Most foam calls start with a cold basement, a drafty room over the garage or an older house where the walls never seem to hold heat. Around the Twin Cities, the price runs higher when old insulation has to come out, when the walls and ceilings are already finished, when foam gets injected into closed walls or when the attic is hard to get into, and the size of the area and how thick it goes matter most of all. The schedule mostly turns on the time of year and on a permit, because Apple Valley's Building Inspections Division issues permits and inspects work under the state building code and city rules, and if the city asks for one on your job, we handle the paperwork and set up the inspections. If you're planning to frame along a basement wall later, tell me early, since Minnesota rules want closed-cell foam sprayed right onto the foundation wall with a gap left between the wall and any framing. The estimate is where you get your own number.

What closed-cell foam looks like
How we install closed-cell foam insulation
I start by looking, because foam seals in whatever's behind it, so a leak, a wet spot or old insulation full of droppings has to be found and dealt with before anything goes on. Closed-cell gives you more insulation per inch but costs more, so we only suggest it where that trade is worth it, like a basement wall, the floor over a garage or an attic where the ductwork lives. If anyone at home has asthma, allergies or skin trouble, I want to know before we book, since EPA says people with those histories should read the product information carefully before choosing spray foam and may want safer options, and I'll talk those through with you. On the day, our crew pulls out any soaked or dirty insulation, masks off what shouldn't get foam and sprays onto clean, dry surfaces, paying close attention to the edges and corners where coverage tends to run thin. Then we clean up, and you stay out until the foam has cured.
Closed-cell isn't the only foam worth pricing, and when budget or noise between rooms matters more than inches, we'll put it side by side with open-cell foam insulation. Property managers and business owners call us too, and our commercial insulation work brings the same foam to offices, shops and rental buildings.
Why Apple Valley homeowners call us for closed-cell foam

I'd rather answer the same question three times than have you agree to foam you don't really understand, so I walk you through what I found before we talk materials. The work is backed by our satisfaction guarantee.
The thing that matters most with foam is finding what's wrong before it gets sealed in for good. Call (651) 268-6025 or send us a message, and I'll come take a look.

What happens after you call about closed-cell foam in Apple Valley?
Call or send a message
Reach us at (651) 268-6025 or through the form, and we'll set a time for me to come out. Our hours are Monday through Friday from 8 AM to 10 PM and weekends from 6 AM to 9 PM.
I walk the space with you
I look over the attic, walls, basement or crawl space with you and tell you what I found and what I'd do first. That includes whether closed-cell is worth its price there or whether something cheaper does the job.
Pick a day that suits foam
Once you decide, we choose a day with temperature and humidity in mind, because both affect how the foam cures. You line up somewhere for the family and pets to stay while we spray.
Our crew sprays, I check
Our installers spray the foam and clean up, and I look over the work before we call the job finished. You come home once the cure time for that foam has passed.
Closed-cell foam questions from Apple Valley
How much does closed-cell spray foam cost in the Twin Cities?
Closed-cell spray foam in the Twin Cities usually costs about $3,300 to $4,900 for 1,000 square feet at 3 inches thick. That's what the work generally runs around here, not our quote, and a basement wall, a garage ceiling or a whole attic will each land differently depending on size, thickness and how easy it is to reach. I'll give you a number for your house at the estimate.
How long do we have to stay out of the house after spray foam insulation?
You stay out during spraying and cleanup and for a while afterward as the foam cures, which is what EPA guidance says, and that goes for kids and pets too. Some foam makers recommend 24 hours before anyone comes back, though it varies by product, so I'll tell you the wait for the foam we're using before we book the day.
Is closed-cell or open-cell foam better for my home?
Closed-cell is the better fit when you need the most insulation in a tight space and want moisture kept out, and open-cell is the better fit when price and quiet matter more. Closed-cell has the higher R-value, which is how well insulation slows heat, and costs more, while open-cell is a much better sound barrier. I'll tell you which one I'd use where once I've seen the space.
What is the best way to insulate an attic, spray foam or blown-in?
For most attics, sealing the gaps first and then topping up with blown-in insulation, loose fill blown through a hose, is the better buy. Closed-cell foam costs more, so it usually only wins when your ductwork runs through the attic and you want it kept on the warm side. Either way, I check what's already up there first, because new insulation over soaked or dirty material just hides the problem.
Can a plumber or electrician work near spray foam later?
Yes, but EPA says plumbers and electricians working near the foam later on should not heat it or grind it, because that can give off toxic emissions. Let anyone doing that work know the foam is there so they can plan around it.
Does an insulation contractor need a license in Minnesota?
A contractor working in more than one skill area needs a Minnesota license, while a specialty contractor offering only one skill area doesn't. The state's Department of Labor and Industry lists insulation and vapor barriers under interior finishing, so ask whoever you hire what work they do and whether they hold a state license.
