How to Seal Gaps in Your Garage Door

Gaps around a garage door may seem like a minor issue, but they can cause big problems. From drafts and water seepage to unwanted critters making their way in, these gaps reduce energy efficiency and may even damage items stored in your garage. Luckily, sealing garage door gaps is a straightforward DIY project that can help keep your garage protected. Here’s how you can fix different types of gaps and ensure your garage door is properly weatherproofed.

Common Garage Door Gaps

Garage door gaps can appear for several reasons, such as settling foundations, worn weather stripping, or misaligned doors. Common places where gaps form include:

  • Bottom of the garage door: This gap can result from worn-out bottom seals or an uneven floor.
  • Sides of the garage door: Often caused by improper door alignment or weather stripping that has deteriorated over time.
  • Top of the garage door: Sometimes the gap can appear due to incorrect door height settings or misaligned tracks.

How to Fix a Gap Under the Garage Door

The most common gap occurs at the bottom of the door, especially during Ottawa’s cold winter months when ground frost can shift the garage floor. Here’s a step-by-step approach to fixing the gap under the garage door:

  1. Replace the Bottom Seal
    • The bottom seal, also known as the weather stripping, helps block out drafts and water. Over time, it can wear out, causing gaps. Replacing it with a garage door bottom gap filler made from rubber or vinyl is an effective way to close the gap.
    • Make sure to choose a seal that fits your garage door track. Measure the door’s width to find the correct size.
  2. Install a Threshold Seal
    • For larger gaps, consider adding a garage door threshold seal. This rubber strip attaches to the floor rather than the door, providing an extra layer of protection.
    • Threshold seals work well for uneven floors or driveways and are excellent for preventing water from seeping under the door.
  3. Adjust the Garage Door Tracks
    • If you still notice a gap at the bottom of the garage door, check the tracks. Sometimes, the tracks may need to be adjusted slightly to ensure the door sits evenly when closed.
    • Loosen the brackets and make small adjustments to align the door properly, then retighten.

How to Seal Gaps on the Sides of the Garage Door

Garage door side gaps can be just as problematic, allowing drafts and pests to enter. Here’s how to seal gaps on the sides:

  1. Install Side Weather Stripping
    • Side weather stripping is designed to close the space between the door’s edges and the frame. Choose a flexible rubber or vinyl strip that can form a tight seal when the door is closed.
    • Attach the weather stripping to the door frame, ensuring that it compresses slightly when the door closes to create a firm seal.
  2. Adjust the Door Alignment
    • Sometimes the garage door has gaps on the sides because it is not aligned correctly. If one side appears higher or lower, try adjusting the tension on the garage door springs or adjust the tracks to bring the door back into proper alignment.
    • If you’re unsure about adjusting the springs, it’s best to call a professional to avoid potential safety hazards.

Fixing Gaps at the Top of the Garage Door

If you notice a gap between the top of the garage door and the frame, it may be due to improper door settings or worn top seals. Here’s how you can fix gaps at the top:

  1. Adjust the Door Opener Settings
    • Sometimes, adjusting the travel settings on the garage door opener can help ensure the door closes tightly against the frame. Refer to the owner’s manual for guidance on how to adjust these settings.
  2. Add a Top Seal
    • You can install a garage door top gap seal to fill any remaining space. This seal attaches to the top frame of the garage and helps prevent air and debris from entering.

Choosing the Right Products for Sealing Garage Door Gaps

When it comes to picking the best materials for sealing garage door gaps, consider factors like climate and the size of the gap:

  • For large gaps, a rubber threshold seal or an adjustable bottom seal works best.
  • For narrow gaps, vinyl weather stripping along the sides and top can provide a tight seal.
  • For Ottawa’s climate, choose weather-resistant materials that can withstand temperature extremes, from harsh winters to humid summers.

Regular Maintenance Tips to Prevent Gaps

Keeping your garage door in good shape is essential to avoid future problems. Here’s how you can maintain it:

  • Inspect the seals regularly: Check for wear and tear every few months, especially before the winter season.
  • Clean the tracks and seals: Remove dirt and debris that may interfere with the door’s operation.
  • Lubricate moving parts: This helps the door move smoothly and can prevent misalignment over time.

The Verdict

Whether you’re dealing with a gap at the bottom, sides, or top of the door, these DIY fixes can help you close the gaps and keep your garage comfortable year-round.
