Open-cell foam insulation in Fayetteville AR - a sealed attic that fits your house
Upstairs too hot and the power bill climbing? We spray open-cell foam under your roof deck so the attic stops leaking air you pay for.
Is open-cell spray foam right for your Fayetteville attic?
Open-cell foam insulation in Fayetteville is foam we spray onto the underside of your roof deck or into open walls, where it swells to fill the gaps, so it insulates and stops air leaks in the same pass. The spraying is the quick part. The time you plan around is the stretch you're out of the house afterward.
Most calls start with a hot room upstairs, a room over the garage nobody can keep comfortable, or a power bill that jumps every summer. Foam is a strong fix when your ducts run through the attic, because sealing the roof deck brings them inside the part of the house you're heating and cooling, but if they don't, I'll usually tell you that sealing the gaps and topping up blown-in insulation is the better buy. The price moves with the size and pitch of your roof, how deep the foam goes and whether old insulation that's wet or full of droppings has to come out first, and the schedule turns on that prep and on a day you can be out of the house. I'll give you the figure for your house at the estimate.

Open-cell spray foam in attics and walls
How we install open-cell foam insulation
Before we spray under a roof deck, we check where your ducts run, because that decides whether sealing the attic pays off. We also talk through how a sealed attic will handle moisture, so you know what you're getting before you say yes. Once you go ahead, we pull out any old insulation that's soaked or full of droppings, fix what caused it, and cover the floors and anything stored up there. If we're sealing the attic, we close off the vents so outside air stops coming in, then our installers spray the underside of the deck and keep the foam as full at the eaves and edges as it is in the middle, since the edges are where crews tend to run thin. We trim it back, clean up and haul off the waste.
Some calls go past the attic. If the damp is coming up from under the house, foam overhead won't fix it, so we often start with a crawl space vapor barrier that keeps ground moisture out. We also spray open-cell foam in shops, offices and rental buildings through our commercial insulation work.
Why Fayetteville homeowners call C&J Fayetteville Insulation Company for open-cell foam
I check every attic myself
I come out to look at every job myself, so the person quoting your attic is the one who crawled through it. Our own installers do the spraying, which means the crew in your house answers to me.
Licensed and insured in Arkansas
Arkansas licenses home improvement contractors by job size, with a Limited license for residential projects under $50,000 in labor and material and an Unlimited one for projects of any size. We're fully licensed and insured, and you should ask any contractor for proof before you hire them.
Started in 2023 to fix causes
I spent years doing upkeep for a property management company, tracing drafty rooms and damp floors back to attics and crawl spaces, and started this business in 2023 to fix them properly. That's why we find the cause before we quote, and I'd rather tell you foam won't help than sell it to you.

Open-cell spray foam questions in Fayetteville
How much does spray foam insulation cost in Fayetteville?
Installing spray foam insulation in Fayetteville usually costs about $2,200 to $8,500 per job. That's the going range for spray foam in general, not open-cell alone, and the size of your attic and the prep it needs decide where you land. I'll give you your own figure at the estimate.
What is the best way to choose between open-cell and closed-cell spray foam?
Choose by where the foam goes, because closed-cell packs more R-value, how well insulation slows heat, into each inch and blocks moisture vapor, while open-cell lets vapor pass through. Open-cell rates about R-3.6 per inch, and closed-cell is about R-6 per inch, rigid, and acts as a vapor retarder. Under a roof deck open-cell is the usual pick, and where blocking moisture matters more, closed-cell foam is usually the better fit.
How long do I need to stay out of the house after spray foam is installed?
Safety guidance advises leaving the house during the install and for at least 24 hours afterward, so plan a place for the family and pets to stay that long. Anyone with a history of skin conditions, respiratory allergies or asthma is advised to read the product information carefully and, if needed, consider another kind of insulation. Ask us about our safety steps before the spray day and we'll go through them with you.
Does sealing the attic with spray foam lower the power bill?
It can, mostly when your ducts are in the attic, where sealing it can save up to 10% of heating and cooling energy. That savings applies to houses with attic ductwork, so if yours run somewhere else, foam is harder to justify and the cheaper gap-sealing fix usually wins.
Will a sealed attic cause moisture problems in my house?
It can raise moisture, so it's worth weighing before you spray. In one study, houses with sealed attics had higher moisture in the attic and the living space, on average, than houses with vented attics. That's the moisture talk we have with you at the start, and if you already see damp floors or sweating windows, we find that cause first.
Do I need a permit for spray foam insulation in Fayetteville?
Check before the job starts, because the city's list of work that doesn't need a permit names things like painting and flooring, not insulation. The city building official issues permits to alter or repair a building, Fayetteville inspects alterations and repairs, and Fayetteville Building Safety asks you to call 479-575-8238 and speak with an inspector about permit questions. Before work starts I check with the city's building office about what your job needs, and when a permit is called for we take care of the paperwork and the inspections.
Work that goes with open-cell foam insulation
Commercial insulation
If you own a shop, office or rental building, the same foam and the same look-first approach carry over to bigger roofs and walls.
Crawl space vapor barrier
When damp air rises from the dirt under your house, a barrier on the crawl space floor stops it before any attic work can help.
