How Much Does Attic Insulation Cost in Oklahoma City?

Blown-in attic insulation in Oklahoma City typically costs about $1.25 to $2.50 per square foot of attic floor to reach R-38 to R-49. For a 1,500 square foot attic, that is commonly about $1,900 to $3,750. Removal of old insulation, air sealing and spray foam change the total, so here is how each piece adds up.

Typical Oklahoma City Attic Insulation Prices

• 1,000 sq ft attic, blown-in to R-38 to R-49: about $1,250 to $2,500
• 1,500 sq ft attic, blown-in to R-38 to R-49: about $1,900 to $3,750
• 2,000 sq ft attic, blown-in to R-38 to R-49: about $2,500 to $5,000
• Old insulation removal: about $0.75 to $2.00 per sq ft
• 1,500 sq ft attic, removal plus new blown-in: about $3,000 to $6,750
• Attic air sealing: about $500 to $1,500
• 1,500 sq ft attic roof deck, open-cell spray foam: about $3,700 to $6,600
• Radiant barrier on a 2,000 sq ft roof deck: about $1,200 to $3,000

What Moves the Price

The biggest factor is how much insulation you already have. An attic with 6 inches of clean fiberglass needs far less material to reach R-49 than one with 2 inches of packed rock wool. Attic size comes next, followed by access: low-pitch attics, small scuttle holes and complex rooflines take longer.

Removal is the biggest add-on. If old insulation is wet from a roof leak, smells, or is full of mouse droppings, it needs to come out before new insulation goes in. Air sealing is the best-value add-on, because once new insulation is blown in, the leaks underneath are buried.

Blown-In or Spray Foam?

For most Oklahoma City attics, blown-in insulation on the attic floor gives the most comfort for the money. Roof deck spray foam costs more, but it makes sense when your air handler and ductwork are in the attic, because it keeps that equipment out of 140°F summer heat. Compare both in blown-in vs rolled insulation.

Rebates That Lower the Cost

The federal 25C tax credit no longer applies to work completed after December 31, 2025, but many OG&E customers can still qualify for OG&E's attic insulation rebate when the home is at least 10 years old and the attic starts under 8 inches or R-23. Read tax credits and rebates in Oklahoma City.
