Is open-cell spray foam the right fix for my attic or crawl space?
Open-cell foam insulation is a soft spray foam that seals air leaks and insulates in the same step. In Lakeville homes we use it most in attics, crawl spaces and along the rim joist, the band of framing that sits on top of the foundation, so the house holds its heat and the power bill usually comes down.
Most people call us about a room over the garage that never warms up, cold floors above a crawl space or a heating bill that keeps climbing. The price moves with how much area gets foam, how thick it goes, how hard the space is to reach and whether old insulation that's soaked or full of droppings has to come out first through insulation removal. The schedule mostly turns on the weather and on whether anything has to be fixed before we spray. Your estimate puts each step on its own line, so you see your own figure before anything is decided.
How we put in open-cell foam insulation
Before anyone sprays, I talk with you about moisture. Open-cell seals air well and costs less than closed-cell foam, the dense kind that blocks moisture, but it lets moisture pass through the way fiberglass does. So every open-cell estimate includes a talk about whether your space needs a moisture layer too, and I'd rather you see that on the quote now than be surprised by it later. On the day, our installers close off the work area, spray around the pipes, wires and the hatch so no gap is left open, and lay the foam at full depth right out to the edges, because thin edges are where the cold usually gets in. When the foam's done, they trim it where it ran thick, clean up and leave the space to air out.
In a crawl space, foam on the walls often goes together with a crawl space vapor barrier over the dirt floor, which keeps ground moisture from rising into the space. We also spray open-cell in shops and offices as part of our commercial insulation work for business owners.
Open-cell foam insulation in Lakeville: permits and the houses we see
The City of Lakeville requires a permit to build, enlarge, alter, repair, move or tear down a building, and that list doesn't name insulation on its own. So the question of whether your foam job needs one goes to the city's Building Inspections office, which takes permit questions before work starts. When a job calls for a permit, we pull it, sign for it and set up the inspections. If we're unsure, we check with the city's building office before we start, so you're not left guessing.
What we see most here are finished basements with a cold rim joist behind the drywall, rooms over attached garages and attics with ductwork running through the cold space, so I check those spots on nearly every visit. We're based in Lakeville and work in many of the cities around it, and we run into the same houses on jobs in Apple Valley and Farmington. If your city isn't on our list, call and ask.

I look and write it up

Our installers spray the foam
Before the day, we tell you when to leave and when you can come back, since that depends on the foam we're using. Plan for everyone in the house, pets included, to be somewhere else while our installers work.

Questions about open-cell foam in Lakeville
How much does open-cell spray foam insulation cost near Lakeville MN?
Installing spray foam insulation in the Minneapolis-St. Paul area usually costs about $2,800 to $11,000 per job. That's the usual range around here, not our price, and where your job lands depends on how much area gets foam, how thick it goes and what has to come out or be fixed first. Your estimate lists each step so you can see your own number.
How long do we have to stay out of the house after spray foam insulation?
You should be out of the house while the foam is sprayed and stay out until it has cured and the space has been aired out and cleaned, which is national EPA guidance. Some foam makers recommend 24 hours before anyone comes back, but that varies by product, so we plan your return around the instructions for the foam we're using.
Does open-cell foam need a vapor retarder in Minnesota?
It can, because a vapor retarder, a layer that slows moisture, may be needed with open-cell foam in colder climates. Minnesota's residential code requires one on the inside of frame walls in Climate Zones 6 and 7, and when open-cell goes on foundation walls the state's energy code has it sprayed right onto the wall, with a vapor retarder and air barrier on the side that's warm in winter. I go over which of those rules applies to your house when I write the estimate.
What is the difference between open-cell and closed-cell spray foam?
Closed-cell is the dense foam that blocks moisture, and open-cell is softer and easier on the budget. Open-cell can also soak up and hold water if it gets wet, so we match the foam to the spot, and a space that stays damp may be better served by closed-cell foam insulation.
Can spray foam insulation be installed in cold weather?
Usually yes, as long as the air and the surfaces are at the temperature and humidity the foam needs and the surfaces are dry. In a Minnesota winter that can mean warming the space first or moving the day, and some foams come in a seasonal version for the weather, so it's fair to ask which one we plan to use.
What is the best way to insulate an attic that has ductwork in it?
When ductwork runs through the attic, spray foam under the roof is often the better choice, because it makes the attic an unvented space and brings leaky ducts inside the part of the house you heat and cool. Without ducts up there, sealing the gaps and topping up blown-in insulation, loose fill blown through a hose, usually does the job for less. That's the call I'll help you make once I've seen the attic.
