A few factors set the price of any insulation job in Collinsville. Attic or wall size, the insulation type you pick, blown-in, fiberglass, or spray foam, and the scope of prep all move the number. If old or damaged insulation needs to come out first, or the attic is tight to work in, that adds to the scope. The honest answer is that we price it after seeing it, with a free evaluation and a written quote for your Collinsville home.
What type of insulation is best for a Collinsville attic?
For most Collinsville homes, blown-in insulation over the attic floor plus air sealing gives you the most comfort for the money, especially with sharp seasonal swings between cold and heat. That combination closes the air leaks and thin spots batts usually leave behind. Where you need to air seal the roof deck or condition the attic, spray foam is the stronger option. The honest recommendation comes after we inspect your attic, not from a script.
How much attic insulation does a Collinsville home need?
For climate zone 4A, where Collinsville sits, the Department of Energy recommends attics at about R-49 to R-60. A lot of the established homes throughout Collinsville were built with far less, commonly R-19 to R-30. During the free evaluation we check your current R-value and tell you how far off you are. Topping up to the recommended level may also qualify for rebates through Ameren and other local utility programs.
Where do you work besides Collinsville?
Our Collinsville crew works throughout Collinsville and nearby areas including Maryville, Caseyville, Fairview Heights, Edwardsville, and Troy. Unsure if your street is covered? Dial (314) 756-5661 and we’ll check in a moment.
How disruptive is an insulation job?
For blown-in insulation, plan on about a day, and there’s no need to leave your home. Spray foam calls for leaving the home for around a day while it cures and off-gasses. Either way, we’ll walk you through the timeline before booking your Collinsville job.
