Your Local Spray Foam Insulation Contractor in OKC
Trusted Spray Foam OKC is owned and run by Garrett Sullivan from our shop at 3401 N May Ave. Oklahoma City homes cover nearly a century of building: older homes on crawl spaces in Nichols Hills, Midtown and the neighborhoods around Capitol Hill, mid-century ranches in Warr Acres, Bethany and Del City, and newer homes with attic ductwork from Edmond and Yukon to Moore and Mustang.
Oklahoma County sits in climate zone 3A. Summers are long, hot and humid, attics pass 140°F, and spring brings hail, high winds and heavy rain. Fiberglass slows heat but lets air move through every gap. Spray foam is a polyurethane foam that expands to fill cracks and gaps, creating an air barrier and adding R-value in a single application.
Every project starts with a free estimate. We check for moisture and past roof damage, measure the space, explain whether open-cell or closed-cell foam fits, and give you a written quote. When blown-in or fiberglass is the better value, we will tell you.

Pricing
Spray Foam Insulation Cost in Oklahoma City
The going rate for spray foam is based on board feet: the area sprayed times the thickness in inches. In Oklahoma City, open-cell foam typically runs about $0.45 to $0.80 per board foot installed, and closed-cell about $1.00 to $2.00. Here is what that means for the projects people ask about most.
| Project | Typical cost | How it adds up |
|---|---|---|
| 1,000 sq ft, open-cell 3 in | $1,350–$2,400 | 3,000 board feet |
| 1,000 sq ft, closed-cell 2 in | $2,000–$4,000 | 2,000 board feet |
| 20x20 garage, closed-cell 2 in, walls and ceiling | $2,000–$4,000 | About 950 to 1,100 sq ft of surface |
| 2,000 sq ft house, roof deck, open-cell 5.5 in | $5,700–$11,400 | 2,300 to 2,600 sq ft of roof deck |
| Crawl space encapsulation | $5,000–$15,000 | Liner, foam walls and dehumidifier |
| New spray foam roof with coating | $4.00–$7.00 per sq ft | Thickness, prep and access |
| 40x60 metal building, closed-cell 2 in | $10,000–$20,000 | Walls and roof |
Planning ranges. Access, old insulation removal and code-required coatings change the total. Your free estimate gives you an exact written price. See our Oklahoma City cost guide.
Choosing insulation
Open-Cell vs Closed-Cell vs Blown-In: Is It Cheaper to Spray Foam?
Blown-in and batt insulation cost less upfront. Spray foam costs more because it also air seals, and in an Oklahoma City attic full of ductwork that air seal is where most of the comfort difference comes from. Here is how the options compare.
| Feature | Open-cell foam | Closed-cell foam | Blown-in fiberglass |
|---|---|---|---|
| R-value per inch | About R-3.5 to R-3.8 | About R-6 to R-7 | About R-2.2 to R-2.9 |
| Air seal | Yes, at about 3.5 in | Yes, at about 1 in | No |
| Moisture | Vapor permeable | Vapor retarder at about 1.5 in | Does not block vapor |
| Best OKC uses | Roof decks, interior walls, sound control | Crawl spaces, metal buildings, roofs, vaulted ceilings | Open attic floors with no ducts |
| Typical cost | $0.45–$0.80 per board foot | $1.00–$2.00 per board foot | About $1.25–$2.50 per sq ft for R-38 |

Rodents and insulation
Do Mice Chew Through Closed-Cell Spray Foam?
They can, but they rarely live in it. Mice tunnel through and nest in fiberglass and loose fill, which is why so many Oklahoma City attics and crawl spaces end up full of droppings. Cured closed-cell foam is rigid, offers no soft nesting material and is not food, so mice tend to move on.
No insulation is fully rodent-proof. The real fix is sealing entry points. Spray foam closes the small gaps at sill plates, rim joists, plumbing and wiring penetrations that mice use, and larger openings at the foundation and roofline should also get steel mesh or hardware cloth. That is also what farmers and shop owners do to keep mice out of equipment buildings.
Keeping mice out of a home or shop
- ✓Remove droppings and contaminated insulation safely
- ✓Seal sill plates, rim joists and penetrations with foam
- ✓Cover vents and larger gaps with steel mesh
- ✓Replace torn blanket insulation in metal buildings with closed-cell foam
- ✓Pair sealing with traps or pest control for an active problem
Honest answers
Spray Foam Concerns: Red Flags, Removal and Insurance
Spray foam gets mixed press. Here are straight answers to the concerns Oklahoma City homeowners raise most.
Why is spray foam now a red flag?
Some buyers and inspectors worry because roof deck foam hides the decking from view and bad installs can cause odor or trap moisture. Nearly every problem traces back to poor installation. Documented, professional work is rarely an issue.
Why are people removing spray foam?
Most removals come from foam sprayed over wet wood, sprayed too thick in one pass, or mixed at the wrong temperature. We check moisture first and spray in proper passes.
Why don't insurance companies like spray foam?
Some insurers and roofers are cautious because roof deck foam makes leaks and hail damage harder to inspect from inside. Fixing roof issues first and keeping product and thickness records answers most concerns.
What are the negatives of spray foam?
Higher upfront cost than fiberglass, about 24 hours out of the home while it cures, and it is hard to remove later. Poor installation causes most of the problems you read about.
Where should you not use expanding foam?
Not over wet wood or an active roof leak, against chimneys or heat sources without clearance, over recessed lights not rated for contact, or over old wiring that has not been checked.
What is the lifespan of spray foam?
Properly installed spray foam does not sag or settle like fiberglass and is generally expected to last for decades, often the life of the building.
Built for Oklahoma weather
Spray Foam, Hail and High Winds in Oklahoma City
Spring storms are part of life in Oklahoma County. Closed-cell spray foam bonds to the roof deck and framing and adds racking strength, and a seamless spray foam roof gives wind fewer edges and seams to lift. Neither replaces a storm shelter or proper roof framing, but both help a building hold together and stay dry.
On flat and low-slope commercial roofs, spray foam roofing with a granulated coating handles most hail well, and damage is usually repaired with simple patches. Before we spray any roof deck, we check for leaks and past hail damage so foam never covers a problem.
Why OKC buildings use spray foam
- ✓Seals air leaks that drive up summer cooling bills
- ✓Keeps attic ducts out of 140°F heat
- ✓Stops condensation in metal shops and barndominiums
- ✓Seamless, insulated roofs for flat commercial buildings
- ✓Reduces thermal bridging and outdoor noise
