How to Replace a Metal Garage Door Weather Seal
A weather seal on a metal garage door, also known as weather stripping, is a strip of plastic or treated rubber, serving as a barrier against harsh weather conditions. It isolates the door and prevents the garage floor from becoming wet and dirty with dust, snow, and wind-driven rain. At the same time, the weather seal keeps out insects, snakes, and rodents by creating a seal between the garage door and floor. Last, it keeps your tools, vehicle, and other items safe and prevents exposure to the elements, reducing the risks of costly moisture and rust damage. However, the weather seal may break down over time, with exposure to extremes of cold and heat and direct sunlight. You can always use the services of a repairman, but replacing the damaged weather seal is not a difficult task. Just follow the guide bellow, and you will have it replaced in no time.
Step 1–Purchase Materials
Look at the old weather seal and find out the type and size you will need for your garage door. One of the most common types in new doors is compression weather stripping, but there are also rigid weather strips, pressure-sensitive adhesive-backed foams, etc. Typically, old doors are fitted with rigid strips and self-adhesive foam stripping which is nailed in place. You will find the exact type of material on the seal’s back once you have it removed. If you don’t see any screws, pull the seal out of the groove, and it will come out easily. If you notice screws, you have to remove them as explained in step 2. Visit the local hardware store and buy the right type of weather seal. For rigid weather strips, you have to also purchase a number of screws. Again, look at the old seal in order to choose the right size of screws.
Step 2–Replace Weather Seal
Compression Weather Stripping
Pull out the old seal if you haven’t already removed it when looking for the type of replacement you need. Put the new piece in place and use aviation shears to cut off some of it, if too long. After that, slip it in back into the slot to seal the air into the house.
Rigid Weather Strips
Use the power screwdriver to remove the screws, sliding the weather seal out of the groove. Look for 2 inward facing grooves at the bottom of the garage door which create a lip. The weather seal at the door’s base is found in this lip, fitted in place by screws. Remove them using the power screwdriver. You have to bow the new weather seal in half when you slide it in. Otherwise, it may not fit in the grooves. After you fit it in place, line up by using the holes in the sides of the door’s bottom and finish by putting the screws.
