How To Seal an Up and Over Garage Door

By Stormstop / 1st October 2024

Sealing around a garage door is essential for energy efficiency, insulation, and pest prevention. If you’re preparing for winter, having a quality up and over garage door seal is even more important for keeping your garage in good condition. To help you stay ahead of the game, this guide covers how to seal an up and over garage door and answers common questions about sealing gaps at the bottom, top, and sides.

 

How Do You Draught Proof an Up and Over Garage Door?

Draught-proofing an up-and-over garage door involves sealing all the gaps where cold air, dust and water can enter. This can be achieved by using different types of up-and-over garage door seals that each serve a specific purpose.

Here are the types of up and over garage door seals you'll need:

 

Tools for Sealing an up and over Garage Door

  • Measuring Tape – For accurate width and length measurements.
  • Utility Knife or Scissors – To cut seals to size.
  • Screwdriver/Drill & Screws – For attaching multi-seals.
  • Cleaning Cloths & Detergent – Clean edges and floor before sealing.
  • Lubricant Spray – Keeps hinges and rollers in working order.

 


 

How to Seal an Up and Over Garage Door from Inside

Sealing an up and over garage door from the inside can help to create an additional layer of protection against draughts, leaves, rainwater and pests. One of the most effective ways to do this is by installing an up and over garage door bottom seal. Here’s how you do it.

  1. Prepare the Door - Close the door, clean edges, and inspect for gaps.
  2. Attach the Bottom Seal - Measure the bottom edge and install a rubber blade up and over garage door bottom seal.
  3. Test - Close the door to check that the seal meets the floor.

For more details, see our bottom seal fitting guide.

 

How Do I Cover the Gap at the Top of My Garage Door?

The gap at the top of the garage door can be a prime source of draughts and water leakage. To fix this, you’ll need to install an up and over garage door top seal. Garage door multi seals can be fitted along the top edge of the door to create an effective seal. 

  1. Measure & Clean - Measure the top edge, then clean the area.
  2. Cut and Attach - Cut the multi-seal to fit, peel backing, and apply along the top. Add screws for extra hold.
  3. Test & Adjust - Check for gaps after closing the door and adjust if needed.

How Can I Seal the Sides of My Garage Door?

To seal the sides, the multi seal works as an up and over garage door side seal and can be fitted in the same way as the top seal.

  1. Measure, Cut & Attach - Measure each side, cut the seal to size, and apply along the door frame.
  2. Secure with Screws - Ensure a firm hold by adding screws along the edges.

 

How Do I Close the Gap Between My Garage Door and Floor?

You can install a garage door floor seal to close the gap between your garage door and the floor. This creates a durable barrier to block out cold air, water, and debris:

  1. Choose a Seal - Select a rubber or vinyl threshold seal to fit the gap.
  2. Prepare the Surface - Clean the floor area, mark the placement, and apply adhesive.
  3. Attach & Cure - Place the threshold seal along the adhesive, then allow 24 hours for curing.

How Do You Maintain an Up and Over Garage Door?

Regular maintenance keeps your up and over garage door seal effective:

  • Inspect Seals - Check multi-seals, bottom seals, and threshold seals for wear every few months.
  • Lubricate Parts - Apply lubricant to hinges and rollers for smooth operation.
  • Clean Regularly - Remove dirt from the edges for a consistent seal.
  • Check Door Alignment - Ensure the door closes flush with the frame.
