How to get the most out of your Garage Door Seal

Garage door seals are great, but you need to use them in conjunction with other types of weatherproofing or insulation to get the most out of them. For instance, using a garage door insulation kit is a good idea if you want maximum protection against the elements. I have a post on the best garage door insulation kits here if you want to check them out.

The installation of a garage door seal is unbelievably simple. Just use adhesive, it will usually come with the seal, and make sure you’ve trimmed it to fit your garage door. Most seals come in the size of 16 feet or 20 feet, so assuming you won’t need all of that, I’d suggest cutting it to fit your garage and saving the rest for when you might need to replace the seal.

Finally, there isn’t much to garage door seals, however, I’d personally suggest buying a seal with the yellow safety strip or adding one yourself especially if you’re planning to use/be in your garage when it’s dark and/or if you have children running about. Tripping on a hard, usually concrete floor is something I definitely try to avoid, garage door seals shouldn’t be the reason for an injury, make sure you securely attach it to the floor and be mindful, so you don’t trip and fall.
