Why Is It Important to Seal Your Garage Door?
A well-sealed garage door can offer multiple benefits, from improving energy efficiency to keeping your garage cleaner and safer.
Here are some of the reasons why sealing your garage door is important:
1. Energy Efficiency
Sealing your garage door can help regulate the temperature in your garage.
If your garage is attached to your home, sealing the door will help prevent heat loss in the winter and keep your garage cool during the summer.
By preventing air from escaping, you can reduce your heating and cooling costs.
2. Protecting Your Garage from Water
When it rains or snows, water can seep in through the edges of an unsealed garage door, leading to moisture problems, including rust, mould, or even damage to your stored items.
Sealing the door can help protect your garage from these weather-related issues.
3. Preventing Pest Infestation
A poorly sealed garage door can be an open invitation to pests, including insects, rodents, and other small animals.
Sealing the door prevents these unwanted visitors from making their way into your garage and home.
Types of Garage Door Seals
There are several types of seals available for garage doors, each designed to address different issues. Here are the most common types:
1. Bottom Seal
The bottom seal, also known as a weatherstripping or threshold seal, is the most important seal on a garage door.
It is installed at the bottom of the door to prevent air, water, dust, and pests from entering through the gap between the door and the ground.
Types of Bottom Seals: These can be made from various materials, including rubber, vinyl, or silicone.
Some models have a flexible lip to provide a tight seal, while others feature a more rigid design.
2. Side and Top Weatherstripping
Weatherstripping along the sides and top of the garage door helps to seal the edges where the door meets the frame.
This type of seal prevents air from entering, which helps maintain temperature control and reduces energy loss. It also keeps debris from getting inside your garage.
Types of Weatherstripping: Common materials include foam, rubber, and felt, which provide different levels of protection depending on your needs.
3. Threshold Seal
A threshold seal is a rubber or vinyl strip placed along the bottom of the garage floor.
This seal works in conjunction with the bottom seal to create a barrier between the garage and the outside elements.
Types of Threshold Seals: Some threshold seals are simply flat strips, while others are raised or have a lip that fits snugly under the garage door to provide better sealing.
How to Seal Your Garage Door: Step-by-Step Instructions
Now that you understand the importance of sealing your garage door, let’s take a closer look at how to go about it. Follow these simple steps to seal your garage door effectively.
Step 1: Inspect the Garage Door
Before you start sealing your garage door, take a close look at the door and its components. Check for any visible gaps, cracks, or wear and tear that could be letting in air or moisture.
You’ll also want to inspect the existing seals to see if they’re damaged or worn out.
Tip: If your garage door is old or the seals are brittle, it may be time to replace them entirely for a more effective seal.
Step 2: Clean the Surface
Clean the area around the garage door where you’ll be applying the seal. Dust, dirt, or old sealant can affect the adhesion of the new seal, so it’s important to clean the surface thoroughly.
Use a cloth or a soft brush to remove any debris.
Tip: If there’s old weatherstripping on the door, remove it carefully using a utility knife or scraper.
Step 3: Measure and Cut the Seal
Before applying the new seal, you need to measure the length of the door’s edges (top, sides, and bottom) and cut the seal to fit.
Use a measuring tape to ensure you have the correct measurements. For a bottom seal, it’s important to cut the seal precisely to fit the width of the door.
Tip: Leave a little extra length on the seal, as you can trim it down after fitting it into place.
Step 4: Apply the Bottom Seal
Start with the bottom seal, as this is the most important part.
If you’re using a rubber or vinyl bottom seal, simply press it into place along the bottom of the door, ensuring that it aligns evenly with the edges.
Some bottom seals come with adhesive backing for easy installation, while others require a nail or staple gun to secure them.
Tip: Make sure the seal is flush with the bottom of the door, with no gaps between the door and the seal.
Step 5: Install Side and Top Weatherstripping
Once the bottom seal is in place, move on to the sides and top. Apply weatherstripping along the edges where the door meets the frame.
Cut the weatherstripping to size and ensure it is securely attached to the door frame. You can use adhesive-backed weatherstripping or use a stapler or nails to secure the strips.
Tip: Ensure that the weatherstripping is applied evenly and firmly so that there are no gaps for air or water to seep through.
Step 6: Check the Seal and Adjust if Necessary
After the seals are installed, close the garage door and check the results. You should see that the door is now flush with the floor, and there should be no visible gaps around the edges.
Open and close the door a few times to ensure everything is functioning smoothly.
Tip: If you notice any gaps or unevenness, adjust the seals accordingly for a perfect fit.
Benefits of Sealing Your Garage Door
By sealing your garage door, you can enjoy several benefits, including:
1. Improved Energy Efficiency
Sealing your garage door helps maintain a stable temperature inside your garage.
This can reduce the amount of heat or cold air that enters your home, thus lowering your heating and cooling costs.
2. Better Protection Against Weather
A well-sealed garage door helps keep rain, snow, and wind from entering the garage.
This is particularly important if you live in areas with harsh weather conditions, such as rainy regions or places with heavy snowfalls.
3. Pest Prevention
A sealed garage door prevents rodents, insects, and other pests from getting inside. This is especially important in areas where wildlife and insects can be a nuisance.
4. Enhanced Comfort
If your garage is connected to your home, sealing the door helps create a more comfortable living environment by keeping drafts out and maintaining a consistent indoor temperature.
