Benefits of Garage Door Threshold Seals
While garage door threshold seals have a lot of benefits, we have listed the three most prominent among them for your knowledge.
- Barrier Against External Factors: Even though garages are fairly protected due to a large door and a roof to shield them from trespassers, a complete barrier is still missing without a garage door seal. It’s because of this seal that the open space between the garage floor and door can be closed completely for protecting the indoors from the outdoors.
Moreover, installing a garage threshold seal shields your garage from cold weather and heavy rains that can come in through the door gaps, small cracks, etc. A garage weather seal further increases the life of your garage if everything remains safe inside from external factors.
- Protection for the door: An average garage door needs to be opened and closed several times, which makes it quite prone to damages when it opens and closes. That’s where garage door seals provide doors with a cushioning that helps the door succumb to the heavy beating. Acting as a foam for the door, a weather seal makes sure that the garage door does not bang on the concrete flooring every time (Source).
- Insulation Against Extreme Temperatures: People often keep a lot of things in their garage beside a car that is vulnerable to extreme cold or heat. To ensure that your valuables stay damage-free, you can add a threshold seal so that the outside temperature does not affect the indoors.
How Door Threshold Seals Work?
Most garage door threshold seals are made of two separate parts. These are the actual cushioned bottom of the garage door itself, and the liner that you attach to the ground below it.
This is usually done with an industrial adhesive and can be removed at any time without damaging your property at all. Acting as a wedge, the liner raises off of the ground just enough for the garage door to create a perfect seal.
Its raised design helps to aide with water resistance. The standard width of these under garage door thresholds are 3-inches, with extra-large 6-inch options also available for purchase.
How to Install Garage Door Seals
Installing garage door thresholds seal is actually a very simple process. We’ll lay out all of the steps so that you can easily do this by yourself.
- Clean the area. Before even thinking about laying down your new seal, make sure that the entire surface of your garage floor is clean. Any excess dust or debris could weaken the adhesive, causing a loose threshold liner.
- Lay down adhesive. Lay down some adhesive, which should be included with your garage door threshold seal kit. Simply squeeze a liberal amount along the entire length of the garage door. Try to do this in a zig-zag pattern for the best results.
- Apply the threshold seal liner. Line up the threshold seal and press it into place perfectly.
How Much Does a Garage Door Threshold Seal Cost?
A garage door bottom seal can cost you anywhere between $50 to $200, depending upon the material, brand, and length of the seal. For interior doors, you might not need to apply a lot of garage door bottom seals.
On the other hand, you are going to need a long seal strip for an exterior garage door because it will be broader in size. If you do it yourself, then you just pay for the seals, but if you are using an expert to install it for you, then you will have to pay a few bucks more for the installation costs, which can differ from region to region.
How are Garage Door Seals Fitted?
For the fitting, ensure that when the garage door is in a closed position, it offers firm and tight closure. Positioning the threshold in front of the door is ill-advised, as it will cause water to seep in after running down on the face of the door.
The seal mostly comes in two materials, vinyl, and aluminum. We recommend the flexible vinyl because it lasts longer, is not corroded by water, and is durable.
Although the garage door seals differ when being set up for domestic and industrial use, one similarity that remains is that the threshold is normally notched around the door channels.
How to Choose the Correct Height for the Threshold Seal
To choose the right size for your garage threshold, you just need to measure the space between the garage floor and the garage door from various positions. From those N number of positions, select the largest one. We measure from multiple positions as the floor is not always leveled flawlessly, so measuring from four or five places will ensure that you have the correct height for the threshold seal.
After that, find the right level of shielding you require for your garage door against rainy weather, storms, and other severe factors. A seal with large height will help protect yours indoors against water and other issues. If your home is in an area that often faces heavy storms and flooding, you should go for a seal with a decent height to keep the water out of the area.
Additionally, if you want to install a larger seal to barricade your indoors from the severity of standing rainwater and storms, you can mount a taller threshold, and place it a little away from the door. That way your door can close easily.
How to Choose the Correct Length For Your Garage
To get the right length for your garage door seal make sure to measure the width of the garage door opening. Technically, you should have a longer door seal available than the width of the door opening so that you do not run out of it during the installation.
For instance, if your garage door width is around 9 feet, then you need to have a garage door threshold seal of 10 feet 3 inches long. These seals can be cut easily to the appropriate length using a hacksaw or a pair of scissors, based on the seal material.
How to Create a Water-Tight Seal
To ensure maximum safety, we recommend you create an appropriate threshold so that it sits around the door frame properly. For a watertight seal, you will also need to cut the threshold in such a way that there is no gap in between them. You can do this by using sharp scissors, a box cutter, or a hacksaw.
Place the seal properly behind the door so it has a snug fit. Then, mark the edges on both sides where the threshold seal will need to be cut to fit in in the door channel or frame. That way, you can ensure the area has little entry of water or debris inside the room, ensuring a dry and clean garage. Make sure the threshold’s hump touches the garage door completely without leaving any gap or spacing in between.
If there is gapping, you will need to make the necessary adjustments wherever needed. We recommend using a high-density foam that you can insert in the gaps to cover them completely, allowing you to close off the area and prevent water or debris ingress.
High-density foam blocks are ideal for traditional garage doors that have gaps between the door and the floor. Applying the foam with the help of a high-quality sealant and adhesive will make the area completely waterproof.
Factors to Consider When Installing the Best Garage Door Threshold Seal
Before we look at the factors to consider before installing a garage door threshold installed it is important that we know what it is and how it works.
To find a fitting threshold for your garage, take measurements of three different positions. Take note of the measurements between the garage door and the floor and determine the largest distance.
It is prudent to take three measurements because it is highly unlikely that your floor is completely level.
If rain protection is a major concern, then you should consider getting a high seal. The more protection you need, the higher the seal needs to be. It goes without saying, people who live in areas prone to flooding or heavy storms should consider getting ultra-high threshold seals.
If for any reason you need more protection against more severe storms or standing water, a taller threshold will serve you well. Just make sure to push it back slightly, so that it does not impede the garage door’s opening and closing mechanism.
To land the correct length of seal for your garage door, you need to measure the width of your garage door from one end to the other. For proper installation, take a seal that is at least 2 inches more than the length discovered.
For instance, if you find your garage door measuring 10-inches go for a Garage Door Threshold Seal that is 12 inches long. Thresholds can easily be reduced to fit by using a pair of scissors or a hacksaw depending on its material.
For a watertight seal, the threshold ought to be cut to fit the door channel. After making the necessary size adjustments to the seal, ensure that the hump stays behind the garage door. This will guarantee that no adjustments will be required in the future.
Older garage doors often came with open tracks that left some space between the wall and the track where water would trickle in. To solve this problem, go for a garage door threshold seal that comes with high-density foam inserts.
These do a great job of blocking off the gaps and preventing water ingression through these structural spaces.
Considering the seal quality, we use two common materials mentioned earlier, vinyl, and aluminum. We highly recommend vinyl, as it is sturdy and able to resist a host of different elements, including water and direct sunlight.
In addition to exposure to elements, the quality also determines the longevity of the install. A flimsy construction will be susceptible to breakages especially when put up against the strong wind and water currents for a long time.
For a proper idea of what weight limits a placed on a product go through the manufacturers’ fine print carefully. Many manufacturers will group threshold seal sizes versus the weight of vehicles it can support without collapsing.
The seal sizes vary from 1-2 inches and can support vehicles weighing from 4500 pounds to airplanes of 50 tons depending on the size of your garage.
You might feel like hiring a professional to install a garage door threshold seal or rubber seal, but you might install it on your own. Changing seals or installing a new one through a professional can be a costly service, so why not do it on your own?
With a little bit of patience, an extra person to help, and dish soap you can replace the garage rubber seal yourself. During the installation, you will also need markers, measuring tape, and adhesive sealant to install the new threshold seal in place. Another thing to note before installing the seal is to clean the dust and grease from the area.
We mentioned earlier that you need a good-quality sealant that adheres to either the floor or door. That’s how the garage door seal stays in position and keeps the area sealed efficiently. Before choosing a door seal for your garage door, make sure to check whether the T-ends match with the door track of your garage. The adhesion sticks perfectly with the door seal only when the T-ends stick to the track completely.
Additionally, extra width is always good for the seal as it makes it adhere in place tightly. Another thing to note is that the door seals mentioned in the list in this post do not come with a track replacement kit. You will have to buy that separately to change the old track if needed.
A garage door rubber seal requires high-quality adhesive to have an effective grip over the floor. You will first need to apply two lines of adhesive parallel to each other. After that, you can add a zig-zag pattern between those two lines to let the seal grip the floor as firmly as possible. You can find tons of videos online showing how to apply the adhesive correctly for replacing a garage threshold seal.
Before purchasing a garage door seal kit, make sure to find some value in your purchase. A garage rubber seal with the value might have complimentary offers, good customer service, and a warranty period to give you additional perks. That way, you know your investment was worth it.
Besides the perks, you also want the seal to have high durability and longevity. You might have to spend a few extra bucks but that will be better than purchasing a cheap and low-quality item that is inefficient and counterproductive.
