You have probably noticed dirt, water, or droppings inside your garage at some point in time, and this most likely means that your garage door is not securely sealed off. The seals that most garage doors come with normally break down over time (in extreme cases they even shift over a bit and start to damage your concrete) and it is important to keep up with maintaining this necessary feature. This is one feature that you don’t notice how important it is until it starts to break.
Weather-sealing your garage door is a relatively simple process. You can easily replace the bottom seal and also ad thin weatherstripping to the side door panels to make the door airtight. Listed below are 5 different ways you can weather-seal your door to make sure nothing goes in or out without your consent.
This could also be known as the door sweep, and it is a long strip of rubber that is attached to the bottom of your door. Once you are able to see sunlight come through the bottom of the door when it is closed you should think about replacing the seal.
Most wood garage doors use simple seals with angled edges, and they are installed with simple roofing nails. If you have a metal garage door they usually have an aluminum channel on the bottom of the door that holds a astragal seal, also known as a T-style.
This seal slides into two tracks for installation. These types of seals are very easy to install, and they also come with different sizes to seal different heights of gaps. This is overall an easy fix for cracked or sunken garage floors.
This has a similar function to the above seal, but it is attached to the floor itself instead of the door. These are best used to keep out water when the driveway angles down a bit, and in particularly wet climates.
These are also very useful in filling large gaps below doors. Vinyl threshold seals are more durable to use for this type of seal and they are installed by using an adhesive usually included with the threshold.
Remember that this works both ways in your garage, so if you are hosing down your garage anytime soon, or even sweeping out dirt, this could prove difficult with this sort of seal.
The elements can also get into the garage through the sides and top of the door. There is usually rubber weatherstripping on the wood door stop molding on the door jam to prevent this.
If your door doesn’t have this you should think about doing this yourself by buying new weatherstripping rolls, cutting it to length, and installing it with some nails. You should tell it is on tightly if the door-side flange of weatherstripping presses well against the door.
This is a great option for old and rotten door stops. This is usually made out of vinyl with a wood-looking molding strip with a flexible weather-seal flange in one piece. This is very easy to cut with a saw and you can, once again, use steel siding nails.
Make sure to push the molding towards the door so the weatherstripping flange is compressed and then fasten the molding to the door with your nails.
Individual door panels can be sealed off with V-shaped panel weatherstrips. This is much more useful on older wood doors with flat edged panels. These strips are sold in rolls and are self-adhesive.
Simply stick to each panel flatly, and when the door is closed the panels should compress the weatherstripping to create a more effective seal.
