How to seal double doors?

Welcome back to the MM Garage Door Repair Utah blog! As your trusted local garage door experts, we’re always here to help you keep your garage in top shape. One common issue we see is air leakage around garage doors, especially double doors. This can lead to higher energy bills, drafts, and even pest intrusion. So, the question is: How do you effectively seal double garage doors? Let’s dive into the details!

Why Sealing Your Double Garage Doors Matters

Before we get into the “how,” let’s quickly cover the “why.” Properly sealing your double garage doors offers several key benefits:

• Energy Efficiency: A well-sealed garage prevents heat from escaping in the winter and cool air from escaping in the summer, reducing your energy consumption and saving you money.
• Pest Control: Gaps around your garage doors are an open invitation for insects, rodents, and other unwanted guests. Sealing them up keeps these critters out.
• Weather Protection: Sealing helps protect your garage and its contents from rain, snow, wind, and dust.
• Noise Reduction: A tight seal can help dampen outside noise, creating a quieter environment inside your garage.

Identifying the Problem Areas

The first step in sealing your double garage doors is to identify where the leaks are occurring. Common problem areas include:

• The bottom of the doors: This is where the door meets the floor.
• The sides of the doors: Where the door edges meet the door frame.
• The top of the doors: Where the door meets the header.
• Between the two doors: The center where the two doors meet on a double garage door.

A simple way to check for leaks is to stand inside your garage on a sunny day and look for light shining through any gaps. You can also use a lit candle or incense stick and hold it near the door edges. If the flame flickers or the smoke wavers, you’ve found a leak.

Tools and Materials You’ll Need

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

• Garage door bottom seal: This is a rubber or vinyl strip that attaches to the bottom of the door.
• Garage door side and top seal (weatherstripping): This comes in various materials like rubber, vinyl, or foam.
• Center seal (astragal): This is specifically designed to seal the gap between the two doors.
• Utility knife or scissors: For cutting the seals to the correct length.
• Measuring tape: For accurate measurements.
• Hammer or screwdriver: Depending on the type of fasteners used for the seals.
• Caulk gun and exterior-grade caulk: For sealing small gaps and cracks.
• Clean rags: For cleaning surfaces before applying seals.
• Safety glasses and gloves: For personal protection.

Step-by-Step Guide to Sealing Double Garage Doors

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

Step 1: Prepare the Area

Start by cleaning the areas where you’ll be applying the seals. Remove any dirt, debris, or old sealant. Use a scraper or putty knife to remove any stubborn residue. A clean surface ensures proper adhesion of the new seals.

Step 2: Install the Bottom Seal

The bottom seal usually slides into a channel on the bottom of the door. Measure the width of your garage door and cut the bottom seal to the appropriate length. Slide the seal into the channel. You may need to use a lubricant like silicone spray to help it slide in smoothly. If your door doesn’t have a channel, you can purchase a bottom seal that attaches with adhesive or screws.

Step 3: Install the Side and Top Seals (Weatherstripping)

Measure the length of the side and top jambs of your garage door opening. Cut the weatherstripping to the correct lengths. Apply the weatherstripping to the jambs, ensuring it makes good contact with the door when it’s closed. Most weatherstripping has an adhesive backing, but you may need to use screws or nails for added security, especially in high-wind areas.

Step 4: Install the Center Seal (Astragal)

The center seal, or astragal, is crucial for sealing the gap between the two doors. Measure the height of the doors and cut the astragal to the correct length. Attach the astragal to one of the doors, ensuring it overlaps the other door when closed. This seal often comes with pre-drilled holes for easy installation with screws.

Step 5: Caulk Any Remaining Gaps

After installing the seals, inspect for any remaining gaps or cracks. Use a caulk gun and exterior-grade caulk to seal these areas. Apply a bead of caulk along the edges of the seals and any other areas where air might be leaking. Smooth the caulk with your finger or a damp cloth for a clean finish.

Tips for a Perfect Seal

Here are a few extra tips to ensure a perfect seal:

• Choose the right materials: Select high-quality seals that are designed for garage doors and can withstand the elements.
• Measure accurately: Precise measurements are crucial for a tight seal.
• Don’t overtighten screws: Overtightening can damage the seals and the door frame.
• Inspect regularly: Check your seals periodically for wear and tear and replace them as needed.

Safety Note

Always disconnect the power to your garage door opener before working on the door. Wear safety glasses and gloves to protect yourself from debris and sharp edges. If you’re not comfortable working on your garage door, it’s best to call 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, but generally, you should replace them every 3-5 years.

Q: Can I use regular weatherstripping from a hardware store?

A: While you can, it’s best to use weatherstripping specifically designed for garage doors, as it’s more durable and designed to withstand the wear and tear of a garage door.

Q: My garage door is uneven with the floor. What should I do?

A: You may need to adjust the bottom seal or consider having a professional level the floor.
