How to seal doors?

Welcome to the MM Garage Door Repair Utah blog! As your local garage door experts, we’re dedicated to providing you with the best advice and service. One of the most common questions we get is about sealing garage doors. A properly sealed garage door not only keeps out the elements – rain, snow, wind, and pests – but also helps to improve energy efficiency and protect your belongings. In this comprehensive guide, we’ll walk you through the process of sealing your garage door like a pro. Let’s dive in!

Why Seal Your Garage Door

Before we get into the “how,” let’s quickly cover the “why.” Sealing your garage door offers several significant benefits:

• Energy Savings: A drafty garage can significantly impact your home’s heating and cooling costs. Sealing gaps prevents heat loss in the winter and keeps cool air in during the summer.
• Protection from the Elements: Rain, snow, and wind can damage your garage and its contents. A good seal keeps these elements out.
• Pest Control: Gaps in your garage door are an open invitation for rodents, insects, and other unwanted critters. Sealing them off helps keep pests at bay.
• Noise Reduction: A well-sealed garage door can help dampen outside noise, creating a more peaceful environment.
• Protection from Debris: Dust, leaves, and other debris can easily blow into your garage through gaps. Sealing helps keep your garage cleaner.

Identifying Problem Areas

The first step in sealing your garage door is to identify where the gaps are. Common problem areas include:

• Bottom of the Door: This is the most common area for gaps, as the rubber weather stripping can wear down over time.
• Sides and Top of the Door: Gaps can occur along the sides and top of the door due to shifting or settling of the door frame.
• Between Door Sections: If you have a sectional garage door, gaps can sometimes form between the sections.

Carefully inspect your garage door, both inside and out, to identify any areas where light or air is coming through. Use a flashlight at night to make it easier to spot gaps.

Tools and Materials You’ll Need

Before you start sealing your garage door, gather the necessary tools and materials. Here’s a basic list:

• New Bottom Seal: Choose a bottom seal that is compatible with your garage door. Measure the width of your door to ensure you get the correct length.
• Garage Door Side and Top Weather Stripping: This is typically made of vinyl or rubber and comes in rolls.
• Utility Knife or Scissors: For cutting the weather stripping to size.
• Measuring Tape: For accurate measurements.
• Hammer or Mallet: For tapping the weather stripping into place.
• Screws or Nails: Depending on the type of weather stripping you choose, you may need screws or nails to secure it.
• Caulk (Optional): For sealing small gaps or cracks.
• Safety Glasses and Gloves: To protect your eyes and hands.
• Clean Rags: For cleaning the surfaces before applying the weather stripping.

Sealing the Bottom of the Garage Door

The bottom seal is crucial for preventing drafts and keeping out moisture. Here’s how to replace it:

1. Remove the Old Seal: Most bottom seals slide into a channel on the bottom of the door. Remove any screws or fasteners holding the old seal in place, then slide it out. You may need to use pliers or a screwdriver to help loosen it.
2. Clean the Channel: Use a wire brush or scraper to clean any debris or rust from the channel. This will ensure a good fit for the new seal.
3. Measure and Cut the New Seal: Measure the width of your garage door and cut the new seal to the correct length using a utility knife or scissors. It’s better to cut it slightly longer than necessary, as you can always trim it down later.
4. Install the New Seal: Slide the new seal into the channel. You may need to use a lubricant, such as silicone spray, to help it slide in more easily.
5. Secure the Seal: If the seal has pre-drilled holes, use screws to secure it in place. Make sure the screws are tight enough to hold the seal securely, but not so tight that they damage it.

Sealing the Sides and Top of the Garage Door

Sealing the sides and top of the garage door is just as important as sealing the bottom. Here’s how to do it:

1. Remove the Old Weather Stripping: If there is old weather stripping in place, remove it carefully. Use a putty knife or scraper to help loosen it if necessary.
2. Clean the Surface: Clean the surface where the new weather stripping will be installed. Remove any dirt, dust, or debris.
3. Measure and Cut the New Weather Stripping: Measure the length of the sides and top of the garage door opening. Cut the new weather stripping to the correct lengths using a utility knife or scissors.
4. Install the New Weather Stripping: Position the weather stripping along the sides and top of the door opening. Make sure it is aligned properly and that it creates a tight seal when the door is closed.
5. Secure the Weather Stripping: Use screws or nails to secure the weather stripping in place. Space the fasteners evenly along the length of the weather stripping.

Sealing Gaps Between Door Sections

For sectional garage doors, gaps can sometimes form between the sections. Here’s how to address them:

• Inspect the Sections: Check the alignment of the door sections. If they are misaligned, you may need to adjust the tracks or hinges.
• Apply Weather Stripping: You can use thin weather stripping designed for this purpose. Apply it to the top edge of each section to create a seal when the door is closed.
• Consider Professional Help: If the gaps are significant or the sections are severely misaligned, it’s best to consult with a professional garage door technician.

Final Solution

Once you’ve completed all the steps above, inspect your garage door to ensure that it is properly sealed. Close the door and check for any remaining gaps. If you find any, you can use caulk to seal them. Apply the caulk carefully and smooth it out with your finger or a damp cloth.

Safety Note

Always disconnect the power to your garage door opener before working on the door. This will prevent accidental operation of the door, which could cause injury. Wear safety glasses and gloves to protect your eyes and hands. If you are not comfortable working on your garage door, it’s best to consult with a professional.

FAQs

Q: How often should I replace my garage door seals?

A: It depends on the climate and the quality of the seals. Generally, you should inspect your seals at least once a year and replace them every 3-5 years, or sooner if they are damaged or worn.

Q: What type of weather stripping is best for garage doors?

A: Vinyl and rubber weather stripping are both good choices. Vinyl is more durable and weather-resistant, while rubber is more flexible and can conform to irregular surfaces.

Q: Can I use spray foam to seal gaps in my garage door?

A: While spray foam can be effective for sealing large gaps, it’s not recommended for garage doors. It can be difficult to control and can damage the door or its components. It’s better to use weather stripping or caulk.

Q: My garage door is still drafty after sealing it. What should I do?

A: Double-check all the seals to make sure they are properly installed and that there are no gaps. If you’re still experiencing drafts, there may be other issues with your garage door, such as damaged panels or misaligned tracks. In this case, it’s best to consult with a professional garage door technician.
