Spray Foam Insulation in Fayetteville, AR

Spray foam insulation in Fayetteville has to handle both seasons. Fayetteville's climate is humid subtropical: July highs average about 89°F, temperatures pass 100°F about three times a year, and January nights average around 25°F at Drake Field, with about 6.5 inches of snow and roughly 47 inches of precipitation a year. We are Spray Foam Insulation Fayetteville, and we insulate and air seal attics, crawl spaces, walls, metal buildings and barndominiums across Northwest Arkansas.

A young, fast-growing housing stock

Fayetteville had 93,949 residents in 2020 and an estimated 106,623 in 2025. The median home was built in 1997, and 24.4% of homes date to 2000 to 2009 and 19.2% to 2010 to 2019. About 58.2% of occupied homes are rented. Newer homes usually need targeted sealing and fixes for hot bonus rooms and attic ductwork. Older ranch homes and rentals often need the basics: attic depth, crawl space moisture control and air sealing.

Climate zone and targets

Washington County is in Climate Zone 4A. Arkansas's residential energy code is based on the 2009 IECC with Arkansas amendments and has been in effect since January 1, 2015. For existing homes in Zone 4, the U.S. Department of Energy suggests R-60 in an uninsulated attic, or about R-49 added where 3 to 4 inches are already in place, and R-19 for floors over unheated space.

Closed cell vs open cell

Closed-cell foam is dense, about R-5 to R-7 per inch, and slows moisture as well as air. We use it on crawl space walls, rim joists, metal buildings and barndominium walls. Open-cell foam is softer, about R-3.5 to R-3.7 per inch, fills irregular cavities and costs less, which makes it common on roof decks over attics that hold ductwork. The Department of Energy recommends against open-cell foam below ground level.

Spray foam insulation cost

HomeGuide lists installed spray foam at $1.50 to $5.00 per square foot: about $1.50 to $3.50 for open cell and $3.00 to $5.00 for closed cell. Foam on a roof deck runs about $1,500 to $9,000 in HomeGuide's figures, and crawl space encapsulation $3,000 to $15,000. Many small jobs carry a minimum of $1,000 to $2,000 or more. Your written estimate, after we measure, is the price.

Hot attics and ductwork

A large share of Northwest Arkansas homes, especially those built since the 1990s, run the air handler and supply ducts through the attic. On a summer afternoon, that equipment sits in some of the hottest air on the property. Two fixes work: seal the ceiling and add depth on the attic floor, or move the insulation to the roofline so the attic stays closer to room temperature. We price both when ducts are in the attic, so you can weigh cost against comfort.

How to compare spray foam insulation contractors

When you search for spray foam insulation companies near me or call insulation contractors, ask each one for the foam type, thickness and R-value of every area in writing, how they handle attic ventilation and crawl space moisture, and how long you need to stay out while the foam cures. Insulation companies that do this well put it on paper. That is how we quote. Get a free estimate
