Gap Around Your Garage Door? Replace the Weather Seal

Gap Around Your Garage Door? Replace the Weather Seal

If you have a gap at the bottom or side of your garage door, it is most likely due to the bottom rubber weather seal deteriorating over time or the vinyl garage door seal may be missing altogether. This is one of the most common problems homeowners face when it comes to garage door maintenance. We are going to take a look at the different types of weather seal you can install at the bottom and around the opening of your garage door to keep out unwanted pests and debris. The two products below are the most popular types of bottom weather seal and vinyl trim for garage door openings on the market today.


The weather seal at the bottom and around the opening of your garage door is designed to keep dirt, leaves, bugs, and rodents out of your garage. Over time this weather seal can deteriorate leaving you with a gap around the garage door. Luckily, there are many solutions to fix this problem and get your garage door back into original shape.

Garage door weather seal is usually made of rubber at the bottom and vinyl at the top and sides of the opening. These materials will wear out over time due to exposure to the elements and will eventually need to be replaced. Replacement weather seals can be found online and any DIY homeowner can perform the repair. In this article we will discuss bottom garage door weather seal, vinyl weather seal for the garage door opening, weather seal for wood garage doors, and how to close up gaps when your concrete is uneven.


Replacing the Garage Door Bottom Weather Seal

The bottom weather seal on a garage door will shrink and stiffen over time causing you to have gaps under your door. Typically, you will see a 3-4” gap on both ends of your garage door due to the rubber material shrinking. This is more prevalent in hotter climates and usually it takes a few years before you start to see the gaps.

Because garage doors spend most of the time in the down position, the bottom weather seal will flatten out and lose its shape. As this happens the seal between the bottom of your garage door and the concrete will lose its effectiveness, therefore requiring replacement. Weather seal will start to lose its pliability quicker in colder climates.

M-D Building Products makes a universal bottom weather seal kit that comes with everything needed to replace the bottom seal on most garage doors. Their kit includes 18ft of bottom rubber seal and aluminum retainer along with the screws needed to attach it. This kit is universal and will fit most garage doors on the market today.

Installing Vinyl Trim Around Garage Door Opening

The first thing we need to determine is the type of trim you have installed on your garage door opening at the sides and top. Many builders install a 1x2 piece of wood to save money instead of the traditional vinyl trim that includes a weather seal. The wood trim does not offer any type of seal to prevent dirt and debris from blowing into the garage.

If you have wood trim around the opening of your garage door, you can remove it and replace it with garage door vinyl trim. The vinyl trim made for garage doors will not rot like wood and it has a seal that is angled toward the garage door so there is a tight fit to the garage door as it closes. This helps prevent wind, rain, and debris from blowing into the garage and also helps keep your garage warmer or cooler depending on the climate you are in.

Installation of vinyl trim is easy and can be done with finish nails and a hammer or using a pneumatic finish nailer preferably with galvanized nails. You want to make sure to use galvanized nails when attaching the vinyl trim to the jamb so the nails don’t rust and stain your trim. After the trim is installed you can caulk and paint it to match your home or the garage door. Be sure not to paint the back side of the vinyl trim as it could stick to your garage door and cause problems.

M-D Building Products manufacturers a garage door vinyl trim that can be used on all types of garage door and can be painted to match the home. The product is easy to install around the top and sides of your garage door opening. It stays flexible during cold temperatures, and helps keeps out leaves, dust, and insects.

Uneven Concrete? Use a Garage Door Threshold

Many homes have uneven concrete where the garage door closes down due to how it was originally poured or the house may have shifted over the years. As this progresses you will start to see a gap under your garage door. This is because a garage door is supposed to be straight with the header. As you drive up to your home everyday, your eye will always see horizontal flaws before vertical.

If your home foundation has shifted and you now have a gap under your garage door, you can install a garage door threshold in the area where the gap is. A threshold is a durable vinyl seal that helps prevent draft, dirt, insects, and rain from entering under your garage door. The threshold can be cut down so you can install it only in the area where you have a gap. This will allow the garage door bottom weather seal to make contact with the threshold therefore eliminating any gaps you might have under the garage door.

M-D Building Products also manufacturers garage door threshold to help in situations with uneven concrete. Installation is easy when using the supplied silicone adhesive and the product is durable enough to be driven over by a vehicle. Closing up the gap at the bottom of your garage door will keep out pests, debris, and draft air therefore making your home more efficient. Its a win, win.

Weather Seal for Wood Garage Doors

If you have older wood garage doors, they will start to smile over time. What this means is the bottom left and right hand corner of the door will start to rise because that is where the tension cable is connected and all the force from the spring is pulling on the bottom section. You can’t do much about the sagging wood section because it is something that took years to create. You can however, install weather seal and threshold.

If you stand back and look at your garage door, you will notice it hits the concrete in the center first. There is not much you can do with the sagging wood section, but you can build it up with a garage door threshold or add nail-on wood door bottom weather seal. Like we discussed previously, you can install a threshold where your garage door comes down and meets the concrete. Garage door threshold is great because you don’t have to use it all the way across your door opening. You can attach it to your concrete where there are gaps and that will provide a seal between the door and the concrete.

If you choose to install weather seal on the bottom of your door, they make weather seal for wood garage doors that is nailed to the bottom to provide a better seal. This weather seal is designed specifically for wood garage doors and is designed to be attached with galvanized nails. The seal is more of a flat design and it has an angled flap that is supposed to be installed outwards to prevent water and debris from blowing under the garage door.
