2024-01-15 8 min read

Weatherstripping is one of the most important yet often overlooked components of your garage door system. Proper weatherstripping protects your garage from the elements, improves energy efficiency, and can save you hundreds of dollars annually on heating and cooling costs.

What Is Garage Door Weatherstripping?

Weatherstripping refers to the seals installed around your garage door that prevent air, water, dust, and pests from entering your garage. There are several types of weatherstripping, each serving a specific purpose:

Bottom Seal (Astragal): This rubber or vinyl seal attaches to the bottom of your garage door, creating a barrier between the door and the floor. It's your first line of defense against water, leaves, and small animals.

Side Seals (Jamb Seals): These run vertically along both sides of your garage door frame, sealing the gap between the door and the frame.

Top Seal (Header Seal): Installed at the top of the door opening, this seal prevents drafts and water infiltration from above.

Signs You Need New Weatherstripping

How do you know when it's time to replace your weatherstripping? Look for these warning signs:

1. Visible gaps or daylight around the edges of your closed garage door 2. Water infiltration during rainstorms 3. Increased energy bills due to air leakage 4. Cracked, brittle, or deteriorating seal material 5. Pest problems - insects or rodents entering through gaps 6. Dust and debris accumulation in your garage

Choosing the Right Weatherstripping Material

Different materials offer various benefits depending on your climate and needs:

Vinyl: Affordable and easy to install, vinyl works well in moderate climates but may crack in extreme cold.

Rubber: More durable than vinyl, rubber weatherstripping handles temperature extremes better and provides excellent sealing.

EPDM Rubber: This synthetic rubber offers superior weather resistance and longevity, making it ideal for Florida's humid climate.

Brush Seals: These feature bristles that conform to uneven surfaces, perfect for older garage floors that aren't perfectly level.
