Weatherstripping is one of the most overlooked yet essential components of your garage door system. This humble strip of material serves as the first line of defense between your garage and the outside world, protecting your home from the elements while improving energy efficiency and comfort.
For homeowners in the Sunapee region, where winters can be harsh and summers humid, proper weatherstripping is particularly crucial. A well-sealed garage door can reduce your heating bills, prevent water damage, and keep pests from entering your home.
There are several types of weatherstripping available for garage doors, each with its own advantages and ideal applications:
Bottom Seals (Astragal) The bottom seal is the most critical weatherstripping component on your garage door. It creates a barrier between the door bottom and the floor, preventing water, debris, and cold air from entering. Modern bottom seals are typically made from flexible rubber or vinyl and should be replaced every 3-5 years depending on usage and weather exposure.
Side Seals (Jamb Seals) Side seals run vertically along both edges of your garage door, creating a tight seal against the door frame. These are often overlooked but play a vital role in preventing drafts and water infiltration. Quality jamb seals are made from weather-resistant PVC or rubber and feature a brush or fin design for optimal sealing.
Top Seals (Header Seals) The top seal attaches to the header above your garage door and prevents air and water from entering through the gap at the top of the door when closed. Like side seals, these should be inspected annually and replaced when showing signs of wear.
How do you know when it's time to replace your garage door weatherstripping? Here are the telltale signs:
1. Visible daylight - If you can see light coming through when the door is closed, your seals are compromised 2. Drafts and temperature changes - Notice your garage getting unusually cold in winter or hot in summer? 3. Water intrusion - Finding puddles or moisture in your garage after rain is a clear indicator 4. Pest problems - Gaps in weatherstripping provide easy entry points for insects and rodents 5. Cracked or brittle material - UV exposure and age cause weatherstripping to deteriorate 6. Increased energy bills - Poor sealing means your HVAC system works harder
