How to Seal Garage Door Sides and Top for Maximum Protection
A garage door is one of the largest entry points to your home. If the sides and top are not properly sealed, it becomes a major source of energy loss and a potential vulnerability for intruders and pests. In the GTA, where winter temperatures drop sharply, preparing your garage door for winter is a necessity.
Effective sealing involves more than just a bottom strip; it requires a comprehensive barrier around the entire frame.
Why a Proper Seal is Essential
Energy Efficiency: A well-sealed door prevents cold air from infiltrating your home during winter and keeps hot air out during summer. This reduces the workload on your HVAC system and lowers utility costs.
Pest and Debris Prevention: Quality vinyl weatherstripping eliminates the small gaps that insects and rodents use to enter your garage.
Structural Protection: Sealing the top and sides prevents moisture from seeping into the wooden door jambs, which can lead to rot and expensive repairs over time.
Operational Quietness: Seals act as a cushion, reducing friction and vibration when the door opens and closes.
Garage Door Seal Options
Depending on your door type and home architecture, there are several specialized sealing solutions:
Vinyl Weatherstripping: Installed on the exterior of the door jamb, this creates a tight fit against the door panels to block wind and rain.
Jamb Seals: These are installed along the interior frame to enhance insulation and fill gaps between the door and the wall.
Brush Strips: Ideal for doors with irregular surfaces, these flexible bristles minimize dust and drafts while allowing for smooth operation.
Bottom T-Seals: These attach to the bottom of the door to form a watertight barrier against the garage floor.
How to Check Your Current Seals
The best way to identify leaks is the “Daylight Test.” On a sunny day, close your garage door and turn off all interior lights. If you see light peeking through the top, sides, or bottom, your seals have failed. In Ontario’s climate, vinyl seals often become brittle and crack over time, requiring replacement to maintain efficiency.
Professional Installation vs. DIY
While some homeowners attempt a DIY approach, professional installation ensures a precision fit. At Dodds Doors, our technicians use heavy-duty, high-grade vinyl that remains flexible in freezing temperatures.
