Understanding the weather stripping of garage door
Maybe you use your garage just for your cars. Maybe it can also be a seminar. Or a storage room. Whatever you use your garage for, you need to make sure it stays dry. Otherwise, what's the point? However, when you went there recently, you found that the weather here was colder than usual. It's still hotter. Even if you clean it regularly, it seems dirty. And, all of a sudden, it looks brighter than usual. That's why you need a garage door weatherstrip.
In general, it is recommended to remove the existing retainer from the bottom of the garage door. In some cases, a new retainer can be installed on the existing retainer, but the new retainer must be firmly installed on the bottom of the garage door.
