Frequently Asked Questions

How much does new attic insulation cost?

The cost of attic insulation varies based on factors like the size of your attic, the type of insulation chosen (e.g., fiberglass attic insulation, spray foam), the required R-value for our climate, and whether old insulation removal is needed. We provide a detailed, no-obligation quote with flat-rate pricing after our free in-home energy audit.

What is the difference between blown-in and fiberglass attic insulation batts?

Fiberglass batts are pre-cut blankets of insulation that fit between standard joists. They are effective but can leave small gaps. Blown-in insulation is a loose-fill material (often fiberglass or cellulose) that is blown into the attic, creating a smooth thermal blanket that fills every nook and cranny, which is often more effective at preventing air leakage.

How long does an attic insulation installation take?

Most residential attic insulation projects, including preparation and cleanup, can be completed in a single day. Larger or more complex projects might take longer, but we will provide a clear timeline with your quote.

Do you offer a warranty on your work?

Absolutely. We offer a comprehensive warranty covering both the insulation materials and our workmanship. We believe in the quality of our service and want you to have complete confidence in your investment.

Is there an ideal time of year to install attic insulation?

Attic insulation can be installed year-round. However, many homeowners choose to upgrade in the spring or fall to prepare for the peak temperatures of summer and winter. This ensures their home is ready to handle extreme weather, maximizing energy savings from day one.
