Why Garage Door Weatherproofing Matters
Your garage door is one of the largest moving parts of your home, and it plays a vital role in protection and security. But beyond keeping your car safe, the door also acts as a barrier against wind, rain, dust, pests, and temperature changes. Without proper garage door weatherproofing, small cracks and gaps can let in moisture and drafts that damage both the door and your home’s energy efficiency.
Weatherproofing is more than just comfort, it saves money on utility bills, prevents structural damage, and extends the lifespan of your garage door.
Common Signs Your Garage Door Needs Weatherproofing
Before diving into solutions, check if your garage door shows these warning signs:
- Drafts inside the garage – Cold or hot air sneaks through gaps.
- Puddles of water near the door – Indicates seal failure.
- Visible cracks or brittle seals – Old weatherstripping no longer works.
- Rust or wood rot on the door – Caused by exposure to moisture.
- Higher energy bills – Leaks force heating and cooling systems to work harder.
If you notice one or more of these, it’s time to invest in garage door weatherproofing.
5 Expert Weatherproofing Tips for Your Garage Door
1. Replace the Bottom Seal
The bottom seal (or threshold seal) prevents water, dirt, and pests from entering your garage. Over time, this rubber strip cracks or flattens. Replacing it is simple and inexpensive but makes a big difference in protection.
Pro Tip: Choose a heavy-duty rubber seal for long-lasting performance.
2. Install Weatherstripping on Sides and Top
Even if the bottom seal is intact, gaps often remain along the top and sides of the door. Vinyl or rubber weatherstripping fills these spaces and prevents drafts.
Pro Tip: Look for UV-resistant weatherstripping to avoid wear from direct sunlight.
3. Add Garage Door Insulatio
If your garage feels like an oven in summer or a freezer in winter, insulation panels are the solution. They keep the garage temperature stable, protect stored items, and improve your home’s energy efficiency.
Pro Tip: Insulated garage doors also operate more quietly compared to non-insulated doors.
4. Seal Garage Floor Cracks
Even with strong seals, cracks in the concrete floor can allow water and pests inside. Use epoxy or concrete filler to repair gaps and create a smooth base for the garage door seal.
5. Maintain the Door’s Finish
Metal doors are prone to rust, while wooden doors can warp or rot. Regularly applying protective paint, sealant, or stain keeps your garage door looking good and protected from harsh weather.
Pro Tip: Wash your garage door twice a year to remove dirt, salt, and moisture buildup.
