We were recently asked if was possible to add insulation into the walls of an older home? The short answer is yes. Especially if the home does not currently have insulation in the wall cavity. The long answer is this: In order to get the new insulation blown into the wall cavity, access points will need to be made in the wall every 12 to 16 inches. Most of the time these access points are located at the top of the wall near the ceiling. Sometimes, we also have to cut in access points near the bottom of the wall as well. In comparison, the cost of adding the insulation and making repairs to the wall are minimal compared to the cost of the monthly utilities being paid out with no insulation in the wall.
