How To Replace Weather Stripping On Bottom Of Garage Door (Step-by-Step)

Let’s start with the exact process to fix your garage door seal.

Tools and Materials You’ll Need

Before starting, gather these items:

• New weather stripping (correct size)
• Measuring tape
• Flathead screwdriver
• Utility knife
• Lubricant (silicone-based)
• Gloves

Step 1: Measure the Garage Door Width

Measure the full width of your garage door.

📏 Example:

• Standard single door: ~8–9 feet
• Double door: ~16 feet

Always buy a seal slightly longer and trim it later.

Step 2: Remove the Old Weather Stripping

1. Open the garage door fully
2. Locate the bottom seal track
3. Slide the old seal out from one side

Tip:
If it’s stuck, use a flathead screwdriver to loosen it.

Step 3: Clean the Track

Before installing the new seal:

• Remove dirt and debris
• Wipe with a dry cloth
• Apply light lubricant

This helps the new seal slide in smoothly.

Step 4: Insert the New Weather Stripping

1. Align the seal with the track grooves
2. Slide it from one end
3. Pull evenly across the entire door

Important:
Make sure the seal is centered and not twisted.

Step 5: Trim Excess Material

Use a utility knife to cut off extra length.

✂️ Leave about 0.5–1 inch (1–2 cm) on each side for proper sealing.

Step 6: Test the Door

Close the garage door and check:

• No visible gaps
• Seal touches the floor evenly
• Door closes smoothly

✅ If everything looks good, you’re done!
