Guarding Against Frost: How to Seal Gaps Around Your Garage Door Before Winter

As winter approaches, sealing gaps around your garage door is one of the most effective ways to protect your home from cold drafts, moisture, and rising energy bills. For homeowners searching online for “garage doors companies near me,” understanding the importance of winter-proofing your garage can save you money and keep your space comfortable all season long.

• Energy Efficiency: Gaps around your garage door allow cold air to enter, making it harder to heat your home and increasing utility costs.
• Protection from Moisture and Debris: Sealing prevents rain, snow, and debris from entering, reducing the risk of rust, mold, and water damage.
• Pest Prevention: Proper seals keep out rodents and insects seeking warmth during winter.
• Extended Door Lifespan: Weatherproofing reduces wear on your garage door system, helping it last longer.

1. Inspect for Gaps and Damage

 

• Check for visible light around the sides, top, and bottom of the door.
• Look for worn or cracked weatherstripping and any loose panels or hardware.
• Use a flashlight at night to spot leaks from inside the garage.

2. Replace or Install Weatherstripping

 

• Bottom Seal: Install a flexible rubber or vinyl strip along the bottom edge to block drafts and moisture.
• Side and Top Seals: Attach seals along the vertical tracks and top frame to prevent air and water infiltration.
• Threshold Seal: For extra protection, add a threshold seal directly to the garage floor.

 

Tip: Always clean and dry surfaces before applying new seals for maximum adhesion and durability.

3. Add Garage Door Insulation

 

• Polystyrene panels or polyurethane foam can be fitted to the inside of your garage door for added thermal protection.
• Insulation helps stabilize garage temperature and reduces the load on your home’s heating system.

4. Lubricate Moving Parts

 

• Cold weather can cause metal components to contract and lubricants to thicken.
• Apply a silicone-based lubricant to hinges, rollers, springs, and tracks to ensure smooth operation and prevent wear.

5. Check the Opener Housing

 

• Ensure the garage door opener and its housing are sealed to prevent cold air from affecting motor performance.

• Durability: Select weatherstripping and seals rated for extreme temperatures and moisture.
• Versatility: Choose seals that fit your specific door type and gap size.
• Aesthetics: Modern seals are available in various colors to match your garage door.
