“He checked out our crawl space and came out with pictures and great explanations. Little did I know that our vapor barrier had been damaged and our wood was starting to mold. He was great at explaining the best insulation methods for our crawl space and gave us separate quotes for each of the projects. Their lead time is fantastic, they keep up with their jobs, so you are only waiting a few days after you make your decision.”

Straight answers

Questions we get every week

Straight answers to the questions homeowners ask us most.

How much does spray foam insulation cost in Northwest Arkansas?
Cost depends on three things: the square footage being treated, open cell versus closed cell foam, and how accessible the space is. Because those vary so much house to house, we price every job with a free in-home estimate, in writing, before any work starts.
Should I choose open cell or closed cell spray foam?
Open cell is the cost-effective choice for most NWA attics and interior walls. Closed cell adds a moisture barrier and higher R-value per inch, which matters for crawl spaces, metal buildings, and rim joists. We recommend based on your home during the free estimate, not on which product has the bigger margin.
Do you offer free estimates?
Yes. Every estimate is free, in person, and in writing. Call us or send the short form and we will schedule a visit, usually within a few business days.
Will new insulation actually lower my energy bill?
In most under-insulated NWA homes, yes, and noticeably. The Department of Energy estimates air sealing plus insulation saves an average of 15 percent on heating and cooling. Homes built before modern code often save more. We will tell you honestly if your insulation is already adequate.
How much does it cost to spray foam a 1,000 square foot area?
It depends on foam type, depth, and access, which is why published ranges are wide: one NWA installer lists $1,700 to $4,200 for 1,000 square feet at three inches. Open cell lands lower, closed cell higher, difficult access higher still. We quote your actual space free, in person, and in writing.
Why will insulation companies not publish exact prices?
Because the same square footage can honestly double in price depending on foam type and access, and a published number would mislead half the callers. The fair substitute is a free written quote that itemizes areas, foam type, depth, and removal, so you can compare bids line by line instead of guessing.
Does spray foam insulation hurt home resale value?
A documented, correct install does not; in a hot Arkansas market, sealed attics are a selling point. The resale problems in the headlines trace to undocumented foam sprayed over aged roof decking, mostly in the UK, where inspectors could not verify the timber underneath. Keep the written scope and photos from your install.
How do I choose between the insulation companies near me?
Read the reviews for specifics rather than the star count: what customers describe is what a crew actually does. Ask each company for a written, itemized quote and proof of insurance, and notice whether they will ever tell you no. A contractor who sometimes says your insulation is already fine is the one whose yes means something.
How long does installation take?
Most blown-in attic jobs are done in one day. Spray foam projects typically run one to two days. Crawl space encapsulation is usually two to three days depending on size and moisture conditions. You get a firm timeline with your written estimate.
What is the biggest real risk with spray foam?
The installer, not the material. Foam is permanent, so a crew that sprays over moisture, skimps on depth, or skips ventilation creates problems that cannot be cheaply undone. Vet the contractor harder than the product: written foam type and depth, a moisture inspection first, insurance you have actually seen.

Your house is leaking money. We have been fixing that since 1996.
