The garage door seal is also recognized as weather stripping and astragal. Seals are found around all four sides of any garage door. The function of the weather seals for garage doors is to keep critters and insects away from the garage while also blocking humid and cold air from entering through the cracks below and sides of the garage door. By weatherproofing the garage door, you can save on your electricity and thus the energy bill and stay warmer throughout the winter.
If there are water, dirt, or rodent droppings in your garage, there’s a high chance the problem has started and entered through your garage door. Garage doors are very massive as compared to other general doors. They usually come with a bottom seal which helps keep out wind, water, dirt, and undesired stuff. However, these seals can themselves break down over the years. In several extreme cases, the driveway apron or concrete floor under the door can settle, shift, or crack, introducing large gaps below the door that standard seals are unable to cover.
Weather-sealing of a garage door is usually a simple and easy procedure. It is done by installing or replacing the sealed bottom of the garage door, and the weather stripping on the stop moulding along the top and sides of the door. Sealing garage door sides are also equally important. You can also go for a lean weather stripping idea between the door panels if you want to achieve an airtight door as much as possible.
Importance of Weather-Seals for Garage Doors
It is also vital to weather-seal your garage door to protect your garage from harsh forces like extreme rains, snowfall, wind, and hail. If water seeps into your garage, it can freeze to form ice and other water damages that can ruin your flooring and easily seep into your living spaces.
If your garage door is in good working condition, then weather-sealing for you would be mostly a DIY job. Sometimes, a garage door needs a gasket adjustment, replacement, or other types of repairs. As it is vital that your garage door must work and seal properly, you may need a professional garage door installation company to handle this tedious job.
Here are five ways that would be helpful to weather-seal your garage door.
5 Striking Seals for Garage Doors
1. Seal Bottom of Garage Door
The garage door bottom seal is also known as door sweep. It is a long strip of vinyl or rubber that is attached to the lower edge of the garage door. When the door closes, this flexible material compresses and seals the gap between the door and the floor to keep out critters, water, dirt, and cold breezes. When you can see daylight penetrating from the bottom of the door, in spite of being closed, you will get to know that it is time to replace the bottom seal.
The wooden garage doors generally use a basic strip-like seal with angular edges that help to seal against the front side of the door and the flooring. These are usually installed with aluminum or galvanized roofing nails.
Whereas metal garage doors usually have an aluminium channel at the bottom of the door that houses a U-shaped rubber gasket, sometimes recognised as an astragal or T-style seal. This gasket just slides into two tiny tracks on the channel for installation. You can also opt for a metal gasket channel instead of aluminium for a wooden garage door so that you can use this type of rubber gasket.
These U-shaped rubber gaskets have several benefits. They are easy to install and are available in a variety of sizes to seal gaps of varying heights. Thus it can be a smart and logical solution for large gaps created by cracked or sunken garage floors.
2. Threshold Seals for Garage Doors
A threshold seal also has a similar function as the bottom seal on a garage door. However, unlike the bottom seal, it is attached to the floor of the garage rather than the door. Thresholds can be used alone or can also be combined with a door seal. They are majorly used to keep out the surface water in cases where a driveway slopes down towards a garage. They can also help cover a large gap at the bottom of the door.
A vinyl threshold seal with good quality is believed to be more durable than a door seal. It is installed with the help of an adhesive that is generally included with the threshold.
As the thresholds block water flowing in the garage, it also blocks it from going out of the garage. Thus it can be inconvenient in cases when you want to hose out your garage. It also becomes difficult to sweep the dirt and debris out of the garage.
3. Garage Door Stop Weather Stripping
There are chances of wind and rain also to enter into the garage through the sides and top of the garage door. To prevent their entry into the garage, these doors generally have vinyl or rubber weather stripping installed onto the wooden door to stop moulding. This door stop is typically attached to the door jamb and almost touches the front side of the door.
You can install new door weather stripping onto your garage door stops if it doesn’t have one or if it has been old and worn out. A worn stripping does not seal any longer against the garage door. New weather stripping comes in the form of rolls, and you can easily cut it to the required length with the help of a utility knife. It is usually installed with galvanized screws or nails. The door-side flange of the new weather stripping must press strongly against the door to form a good seal.
4. Vinyl Door Stop With Integrated Weather Strip
Doorstop moulding combined with weatherstripping is a smart solution for doors that have old, rotten, or destroyed door stops that require replacement. This unique door stop moulding is typically made of vinyl and has a flexible weather-seal flange and a wood-look moulding strip all in one piece. It can be easily cut with the help of a saw and installed with stainless steel or galvanized siding nails.
For installing your doorstep, you need to position each piece such that it is parallel to the door side. After positioning of the pieces is done, then push the moulding towards the door so that the weatherstrip flange gets slightly compressed against the door. It will then get fastened to the moulding to the door jamb present with nails. While installing, it’s recommended to install the top moulding prior and then overlap the ends of the top moulding with the side stops.

5. Garage Door Weather Stripping
For sealing the gaps between individual door panels, there is special V-shaped garage door panel weather stripping designs. This is considered to be particularly helpful for old wooden doors that have panels having flat edges. On the other hand, new fibreglass and metal doors usually possess interlocking edges for preventing air intrusion.
The door panel weather stripping is sold in the form of rolls and it is self-adhesive. You can simply stick it to the bottom or top edge of each panel. When you close the garage door, the panels of the door constrict the weather stripping to produce an effective seal, which is much similar to the weather stripping present on the standard house entry doors.
