Installing new siding on a home can significantly improve its curb appeal. Some types of siding even improve the home’s insulative properties, enabling homeowners to save money on heating and cooling costs. With the right kind of siding and correct installation, your siding should last for several decades, and your siding may only need to be repaired if there is significant damage. Poorly installed siding may allow water to enter your home, causing mold or foundation problems. Despite its durability and long life, siding can be damaged in some circumstances. The siding on the house may become dented, cracked, broken, or even ripped off by strong winds, flying debris, or hail.
