Open-cell foam insulation in Jerome ID - quieter rooms that hold their heat
Drafty rooms, a hot upstairs or a loud room over the garage usually mean air and sound are getting through. Open-cell foam seals and quiets them.

Is open-cell foam insulation right for you?Let's look at your Jerome house


Most calls about open-cell foam insulation in Jerome, ID start with a room that won't behave, like a hot upstairs, a drafty bedroom or the room over the garage where you hear every car door. Open-cell is a soft, porous spray foam, and once it's 3.75 inches thick or more it stops drafts as well as slowing heat.
We do things in order, because foam sprayed over a roof leak, a wet spot or bad wiring just hides the problem until it's bigger. So the fixes come first, and the foam goes on last.
Price comes down to the area we're covering and how deep the foam goes, plus how easy the space is to reach and whether old insulation or repairs come first. Those set the schedule too, along with your family being out while the foam cures, and the estimate gives you a written plan and your price.
You can count on me to explain what's going on in your house before we touch it, so call (208) 544-9045 and ask.
Where open-cell foam insulation earns its place
Open-cell foam goes where air leaks and noise are the problem and there's room for some depth, so I match it to the space instead of spraying everything.
Attic rooflines
We spray the underside of the roof so the attic is closed in with the rest of the house, which makes the most sense when ductwork lives up there.
Rooms where quiet matters
Its soft, open structure soaks up sound better than denser foam, so it's a good pick for bedrooms, home offices and the room over the garage.
Shops and business buildings
Business owners call us about shops and metal buildings too, and we plan the foam around how the space gets used as part of our commercial insulation work.

Open-cell foam questions
How much does open-cell foam insulation cost in Jerome?
Across the US, open-cell spray foam usually runs about $0.45 to $0.65 per board foot, which is one square foot of foam an inch thick. That's the market's typical range, not our price, and because area and depth add up fast, I measure your house and price it at the estimate.
What is the best way to choose between open-cell and closed-cell spray foam?
Start with how much room you have, because one foam maker rates open-cell at R-3.8 per inch and closed-cell at more than R-6.5, R-value being how well insulation slows heat. Only closed-cell works as both an air and a vapor barrier, so if dampness is the worry, closed-cell or a crawl space vapor barrier is usually the better fix. The same maker says open-cell suits milder climates best, though either can be used anywhere, so ask me how that fits your house.
Is spray foam worth the extra cost over blown-in insulation in my attic?
Usually not in a plain attic, because sealing the gaps and topping up blown-in insulation, loose fill blown through a hose, does the job for less. Foam costs more because it seals air while it insulates, and that pays off when your ductwork lives up there, since spraying the roofline brings the ducts inside the sealed part of the house.
How long does it take before we can go back in the house after spray foam?
Plan on being out at least 24 hours, which is what Consumer Product Safety Commission staff advise when spray foam goes in. The actual re-entry time, meaning when you can come back, depends on the foam formula, how much goes into the space, temperature, humidity and ventilation, and EPA guidance says to wait until the foam has cured and the house has been aired out and cleaned. Book the kids and pets somewhere for at least that long, and I'll let you know when it's time.
Is open-cell spray foam safe if someone in my family has asthma?
Talk it over before you choose it, because the commission's staff advise anyone with asthma, respiratory allergies, skin conditions or a past reaction to isocyanates, one of the chemicals in spray foam, to review the product information carefully first. If anyone in your house is in that group, we go over the product information with you and talk about other options, since sometimes another kind of insulation is the better call.
What should I ask an insulation contractor in Idaho before I sign?
Ask for the disclosure statement, because Idaho's contractor licensing office notes that state law requires a general contractor to give you one before a contract over $2,000 to alter or repair your home. The federal safety guidance also suggests asking what time of year suits spray foam where you live and how temperature and humidity affect the job, and that's a fair question to put to me.
