How to seal a double door?

Welcome back to the MM Garage Door Repair Utah blog! I’m your friendly neighborhood garage door technician, here to tackle another common homeowner concern: sealing a double garage door. A properly sealed garage door is crucial for maintaining energy efficiency, protecting your belongings from the elements, and keeping unwanted pests out. Double doors, while offering ample space, can sometimes present a greater challenge when it comes to achieving a tight seal. But don’t worry, I’m here to guide you through the process, step-by-step.

Why Seal Your Double Garage Door?

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

*

Energy Savings: Gaps around your garage door allow heated or cooled air to escape, increasing your energy bills. A good seal helps maintain a consistent temperature in your garage, reducing energy consumption.

*

Weather Protection: Rain, snow, and wind can easily enter your garage through unsealed gaps, potentially damaging stored items, vehicles, and even the garage structure itself.

*

Pest Control: Insects, rodents, and other unwanted critters can find their way into your garage through even the smallest openings. Sealing your door helps create a barrier against these pests.

*

Noise Reduction: A well-sealed door can help dampen outside noise, creating a quieter and more comfortable environment inside your garage and home.

Identifying Problem Areas

The first step in sealing your double garage door is to identify the areas where air and water are entering. Common problem spots include:

*

The Bottom Seal: This is the rubber or vinyl strip that runs along the bottom edge of the door. It’s prone to wear and tear and can become cracked or damaged over time.

*

The Side Seals: These seals run along the sides of the door frame and can become compressed or detached, creating gaps.

*

The Top Seal: Similar to the side seals, the top seal can also deteriorate and allow air and water to enter.

*

Between the Doors (for doors that meet in the middle): This area is especially prone to gaps if the doors don’t align perfectly or if the weatherstripping is damaged.

To check for leaks, you can visually inspect the seals for cracks, gaps, or damage. You can also use a flashlight at night to shine light around the door’s perimeter from the inside. If you see light shining through from the outside, you have a leak.

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 seal that is compatible with your garage door model. Measure the width of your door to ensure you purchase the correct length.

*

New Side and Top Seals: Again, choose seals that are compatible with your door frame. Vinyl or rubber weatherstripping are common choices.

*

Utility Knife or Scissors: For trimming the seals to the correct length.

*

Measuring Tape: For accurate measurements.

*

Hammer or Mallet: For tapping the seals into place.

*

Screwdriver or Drill: Depending on the type of seals you’re using, you may need screws to secure them.

*

Caulk (Optional): For sealing any small gaps or cracks.

*

Gloves and Safety Glasses: For protection.

Step-by-Step Sealing Guide

Now, let’s get to the actual sealing process. Here’s a step-by-step guide to sealing your double garage door:

Step 1: Remove the Old Seals

Start by removing the old bottom, side, and top seals. For the bottom seal, you may need to loosen or remove screws or brackets that hold it in place. For the side and top seals, you can usually pull them out by hand or use a utility knife to cut them free.

Step 2: Clean the Surfaces

Thoroughly clean the surfaces where the new seals will be installed. Remove any dirt, debris, or old adhesive. This will ensure a good bond between the new seals and the door frame.

Step 3: Install the New Bottom Seal

Slide the new bottom seal into the retainer on the bottom of the door. You may need to use a lubricant, such as soapy water, to help it slide in easier. Secure the seal with screws or brackets, if necessary.

Step 4: Install the New Side and Top Seals

Measure and cut the new side and top seals to the correct length. Apply adhesive or use screws to attach the seals to the door frame. Make sure the seals are properly aligned and create a tight seal against the door when it’s closed.

Step 5: Seal the Gap Between the Doors (If Applicable)

If your double doors meet in the middle, install weatherstripping along the edge of one door to create a seal against the other door. You can use adhesive-backed weatherstripping or screw-on seals.

Step 6: Test the Seal

Close the garage door and inspect the seals for any gaps or leaks. Use a flashlight to check for light shining through. If you find any gaps, adjust the seals or apply caulk to fill them.

Final Solution

After completing the above steps, your garage door should be properly sealed. However, if you are still experiencing issues with drafts or leaks, it may be necessary to adjust the door’s alignment or replace other components, such as the hinges or rollers. In some cases, the door frame itself may be damaged and require repair or replacement.

Safety Note

Always disconnect the garage door opener before working on the door. This will prevent accidental operation and potential 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 call a professional.

FAQs

Q: Can I use any type of weatherstripping for my garage door?
