Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls.
