Why is it important to Replace the Garage Door Seal?

This can make it difficult to maintain a comfortable temperature inside the garage, leading to higher energy bills as you try to heat or cool the space. By replacing the seal, you can help reduce drafts and improve energy efficiency, saving you money on your energy bills. 

Water protection: A damaged seal can also allow water to enter the garage during storms or heavy rain, potentially leading to water damage or mold growth.
