Tips for Weather proofing and Sealing Your Sectional Garage Door From the Elements

Begin by checking the seals and weatherstripping on your door. Constant exposure to the elements can cause cracks, detachment, or degradation. Pay special attention to the bottom seal, side seals, and the top strip. Replace any that show signs of wear to avoid letting water or air in.

The bottom seal (also known as a door sweep) blocks water, debris, and pests. If it’s damaged or no longer provides a snug fit, it needs replacing. Remove the old seal by sliding it out of the track, then insert the new one. Make sure it forms a tight barrier when the door is closed. For replacement seals and expert tips, contact your local B&D Accredited Dealer.

A threshold seal (sometimes referred to as an exclude-a-seal) attaches to the garage floor where the door meets the ground, adding an extra layer of protection against water infiltration. The installation process is simple: clean the floor area, apply the recommended adhesive, and carefully press the seal into place. While some water may still enter during heavy rainfall, you’ll drastically reduce leaks. For more sealing supplies, explore our options and upgrades.

Bristle seals along the top and sides of the door help keep dust, sand, and other debris at bay. If these seals are missing or damaged, consider purchasing replacements through a B&D Accredited Dealer. Make sure any new bristle seals align with your sectional door’s specific design.

Another efficient way to regulate temperature and save on energy is insulation. You can opt for insulation kits specifically made for sectional doors, or upgrade to a B&D Panelift Icon equipped with Insul-Shield. Insulated doors can help retain heat during winter and keep the garage cooler over summer.

Even with high-quality seals, small gaps around the door frame might persist. Fill these gaps using caulk or expanding foam designed for exterior use. Sealing them tightly helps prevent drafts and additional moisture intrusion.

While many weatherproofing tasks can be undertaken independently, scheduling a professional maintenance check is advisable. A qualified technician will verify your door’s alignment, spring tension, and sealing performance catching minor issues before they escalate. Regular servicing prolongs your door’s life and helps sidestep costly future repairs.
