"They were very professional, took care of helping me get the home energy audit and the rebates for attic and wall insulation. Also improved attic ventilation installing soffit vents and baffles. We got three estimates and they were a very good price, but the service is what sold us."

"Anthony and his team did an incredible job insulating our full gut remodel in Fairfield. He took the time to put together a foam package that made the most of our budget. The crew was polite, neat and efficient. They took great care to cover finished surfaces before spraying and did a thorough clean up so we could jump right into sheet-rocking. Highly recommended for quality of work, constant communication and value!"

Insulation questions, answered by experts

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

Minimal but regular checks can ensure maximum thermal performance.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.
