At Gold Standard Handyman, we start our garage door insulation installation by thoroughly cleaning out any loose debris and Muddobber nests from the garage door panels. We then cut each foam panel to fit perfectly and install it with expanding foam. This glues it in place and seals off the backside, creating an air pocket. This simple process can cool your garage down by up to 26° in the summer and heat it up by up to 14° in the winter. All of my customers have noticed a significant improvement in their garage temperature after this installation. Get an estimate today!
