Gaps in garage doors are not only unsightly, they can also let in dangerous pests. However, closing off those spaces is a quick and easy way to improve the appearance of your garage and keep your home and car safe. If you are wondering how to seal garage door cracks, you can be sure that it is a quick and painless process.
The easiest way to seal a garage door is to fit grommets. You will need the top, side, and bottom straps, along with the recommended fasteners. All of these materials are available at your local hardware store, and there's also a chance you'll need a ladder.
This article will walk you through the process of sealing gaps on the top, sides, and bottom of your garage door. Let us begin!

1. Measure the garage door
You want to start measuring your garage door. This will help you determine how much peel to buy. Measure the length at the top, middle, and bottom of the garage door, and then find the perimeter of the door by adding all the sides.
I like to use a laser measurer because you don't need help to keep it in place and it's more accurate than a tape measure. But a tape measure will work just fine.
The idea here is to get an estimate of the dimensions of the door so that you can purchase enough sealant. You don't want to go out in the middle of work!
2. Buy strippers and supplies
Once you have your door measurements, it's time to shop for trim and hardware. All of these items can be found at your local hardware store.
Let's say the door is 3 meters wide and 2.5 meters high. That means the perimeter of the gate is 36 feet. You will need 10 feet of bottom straps, 10 feet of top straps, and 16 feet of side straps. You will also need a nail gun or a hammer.
If you need to add concrete where the garage door meets the ground, you'll need to purchase concrete as well. And this is where it gets a bit tricky. It's incredibly difficult to estimate the right amount of concrete for the job, but it's always better to have more than you need.
3. Prepare the area
Now is the time to prepare the area. This is a crucial step as you want to make sure the surface is clean and free of debris. Otherwise, your seals may not fit your garage door correctly.
Start by sweeping the floor and removing any cobwebs. Then use a hose to spray down the connector. Remember to allow the door to dry completely before proceeding to the next step.
If you're in a hurry, you can use a leaf blower to quickly dry the door. Just make sure you don't blow any dirt or debris into the port.
4. Install the lower seal
Now is the time to apply the bottom seam. This is a very important step as the floor seal will help keep water and rodents out of your garage.
- Start by removing the old tape at the bottom of the door. If there isn't one, you can skip this step.
- Then unroll and trim the new seal. You want the fence to be slightly longer than the gate so it can overlap on both sides.
- To install the gasket, start at one end of the door and press the gasket into place. Most of the strips slide over the plastic handrail at the bottom of the door.
However, it may be necessary to use two screws or clamps to secure the seal at the ends. I prefer the screws because they create a tighter grip when stripping. The screws are also easier to remove when you need to replace the stripping.
5. Install the side seals
The next step is to place the side seals. This prevents airflow and insects from entering your garage.
However, do not confuse the side seals with the door jamb seal. The side seals should be mounted on the outside of the door, while the door frame seal should be mounted on the inside.
To install the side seal, start at the top corner of the garage door and nail the seal into place. Continue installing the seal until you reach the bottom corner of the door. Then use a caulk gun to apply a bead of caulk along the outside length of the joint.
6. Apply top seal
The top seal is similar to the side seal. You want to install it outside the door to prevent airflow and bugs.
- First remove the old weatherstripping at the top of the door to fit the top seal. If there is no time track, you can skip this step.
- Now cut the time by measuring the size by measuring the door. Make it a little longer than the door so you can trim it when you're done installing it.
- To install the gasket, start at one end of the door and nail the gasket into place. Remember to seal the outside length of the joint with a bead of caulk.
7. Test the port
Now is the time to test the port. This is a very important step as you want to make sure the door is securely closed before closing it.
Start by opening the door and then closing it. You should hear a hiss when the door closes. This makes the door airtight.
You should check the joints if you do not hear the hiss. Make sure they are secure and have no gaps. After checking that the connector is sealed, you are done with the installation part.
8. Clean up the clutter
This is where most do-it-yourselfers fail. You don't have time to clean up the mess. However, it is important to clean off any caulk or caulk that gets on the door. This will help prevent unsightly clutter from ruining the look of your garage.
Use a damp cloth to wipe off the caulk or caulk that gets on the door. You can also use a putty knife to scrape off excess material. Just be careful not to damage the port.
9. Check the stamps regularly
It is important to regularly inspect the seals to make sure they are still in good condition. You should review them at least once a year. But you may need to check them more often if you live in an area with extreme weather conditions.
If you notice gaps or cracks in the joints, replace them as soon as possible. This is generally a simple and inexpensive task. However, if you wait too long, the damage can run into the thousands.
The advantages of a hermetic garage door
You may be wondering why you should bother sealing your garage door. After all, it's just a door, isn't it?
Incorrect! A sealed garage door has many benefits and I will list the top four benefits below.
A sealed garage door keeps the elements out.
One of the main benefits of a sealed garage door is that it keeps the elements out. If you live in an area with extreme weather conditions, you know how important this can be.
A sealed garage door keeps out wind, rain, snow, and ice. This protects your car and all other items in the garage.
An enclosed garage keeps the bugs out.
Another benefit of a sealed garage door is that it keeps bugs out. Nobody likes to deal with bugs, especially at home.
A sealed garage door prevents insects from entering your home. This is especially important if you have food in your kitchen that you don't want to share with the bugs.
Peeling garage doors keep animals out
If you live in an area with a lot of snakes, you know how important it is to keep them out of your garage. A sealed garage door will do just that.
It will also keep other small creatures like rodents out of the house. This is important if you live in an area where these little critters are a problem.
save energy
An airtight garage door can help you save money on your energy bills. This is because a sealed door keeps cool air inside during the summer and helps trap warm air inside during the winter.
For example, if you have an attic fan, the sealed door will prevent cold air from escaping through the garage. This will help you save money on your energy bill.
How long does disassembly take?
The life of the seal depends on the quality of the product and the traffic that passes through the door. In general, however, stripping can take several years.
Mine lasted about five years before I had to replace it. And that with kids and a dog running in and out of the driveway all the time!
If you live in an area with extreme weather conditions, you may need to replace the caulk more often. This is because the seal is subject to increased wear.
For example, if you live somewhere with harsh winters, snow can build up over time and cause you to wear away faster. I saw this first hand as my stripping time was much shorter at my previous house (which was in a snowy area).
How much does it cost to remove weather from a garage door?
The cost of caulk depends on the size of your door and the type of caulk used. You can expect to spend between $50 and $100.
If you have a very large door or need to use a high-end product, you may need to spend more. But you can probably spend less if you have a small door or use an inexpensive product.
Sealing your garage door is a relatively inexpensive way to improve the energy efficiency of your home. It's also an easy project that most people can do on their own.
If you're thinking of sealing your garage door, I'd say go for it. It's a great way to keep your home closed and save money on your energy bills.
final thoughts
As you can see, a closed garage door offers many advantages. It is important to regularly inspect the seals to make sure they are still in good condition. If you notice gaps or cracks, they should be addressed immediately.
Stripping your garage door is a relatively easy and inexpensive way to improve the energy efficiency of your home. It's also a great way to keep bugs and animals out of your garage. So if you're looking for a way to make your home more comfortable and save on energy bills, you've come to the right place.
