How long your Steel Line Door Seal lasts depends on your location, climate and weather conditions. As a general rule, you should expect your rubber door seal to last at least two years, with the best insulation and energy savings found when combined with a rubber floor threshold seal.
Here are some warning signs to look for when deciding if it’s time to replace the weather stripping:
Water begins to enter your garage near the door.
Pieces of the garage door seal are breaking off when you touch it.
Visible distortions in the stripping, such as cracks or color changes.
The seal is no longer bouncing back into place and leaves a gap between the garage door and the floor.
