Open-cell foam insulation in Hoffman Estates IL - a quieter house with fewer drafts
Drafty rooms or a hot room over the garage? We spray open-cell foam that stops the air leaks and quiets the house.

Is open-cell spray foam right for my house?
Open-cell foam insulation in Hoffman Estates, IL is a soft spray foam we apply right onto attic rafters, walls and the room over the garage, where it fills the cracks drafts come through and slows heat, so rooms hold an even temperature and the house gets quieter.
Most people call Hoffman Estates Insulation Services because a room won't stay comfortable, the power bill keeps climbing or the upstairs bedrooms hear every car going by. We work across Hoffman Estates and the cities around it in the northwest suburbs. The first thing I want to know is where the air's getting in, because foam works best when it's sprayed where the leaks really are.
The price moves with how many square feet we're covering, how thick the foam goes, whether old insulation has to come out first and how hard the space is to reach. The schedule turns on that prep and on the time your family spends out of the house while the foam cures. The estimate is where we pin down your job, and I'll tell you what I'd do first.
- We spray foam into attic rafters, open walls and the room over the garage.
- Old insulation that's soaked or full of droppings comes out before any foam goes in.
- Gaps around pipes, wires and the attic hatch get filled as the foam goes on.
What happens after you call about open-cell foam?
I come out to look at most jobs myself, and our installers do the spraying. Here's how it goes from your first call to the walk-through once the foam has cured.
Call or send us a message
Call (847) 380-5407 or use the form, and tell us which part of the house you're thinking about and roughly how big it is. We get back to you and set a time for me to come out.
I come out and look
I go up in the attic or down in the crawl space, ask what you've noticed and check for wet old insulation and hidden leaks. Then I walk you through what I found, what I'd do first and whether foam is worth the money for your house at all.
Our installers do the work
If you go ahead, we set a day and talk through where everyone, pets included, will stay while the foam cures. Our installers then do the work in the order we agreed on, clearing out bad material first and spraying last.
We go over the finished job
Once the space has been aired out and cleaned, I go over the finished job with you and show you where the foam went and what got sealed. Your satisfaction, guaranteed.

(847) 380-5407Open-cell foam questions from Hoffman Estates homeowners
These are the questions people in Hoffman Estates ask me most about open-cell foam. If yours isn't here, call (847) 380-5407 and I'll give you a straight answer.
How much does open-cell spray foam insulation cost near Hoffman Estates?
In the Chicago area, open-cell spray foam usually costs about $1,900 to $2,900 to cover 1,000 square feet at 3 inches thick. That's the going rate for the work around here, not our price. Your number moves with how much area there is, how thick it goes and how much prep the space needs, and your estimate is where we sort that out.
Is open-cell or closed-cell foam better for my house?
Open-cell is usually better when you want air sealing and a quieter house for less money, and closed-cell is better when moisture is a concern. Closed-cell slows heat about twice as well per inch and can block water vapor too, while open-cell lets vapor pass through but is much better at stopping sound. I'll tell you which one your space calls for after I've seen it.
Can open-cell foam be sprayed in a sealed attic in Hoffman Estates?
Yes, open-cell can be sprayed under the roof to make the attic part of the heated house, but that kind of sealed attic needs a way to get moisture out built into the plan. We work out how the attic will dry before we spray. If moisture looks like a real problem up there, I'll steer you toward closed-cell instead.
How long do we have to stay out of the house after spray foam?
Plan to stay out until the foam has finished curing and the house has been aired out and thoroughly cleaned. Some foam makers recommend about 24 hours for professional systems, but that can vary by product. We'll go over the time for the foam we're using well before the day comes so you can plan a place to stay.
Can an electrician or plumber work near spray foam later?
Yes, they just need to keep heat and grinding off the foam, because burning or grinding it can give off fumes you don't want in the house. We'll show you where the foam is so you can tell anyone who works up there later.
How do I know a contractor can work in Hoffman Estates?
Ask whether they're registered with the village, which every contractor here has to be, and check their insurance, training and references before anyone sprays foam in your house. A crew that's comfortable answering those questions is usually the one you want.
