Weather Stripping & Seals in Glenoma: Why Your Door Leaks Heat
2026-07-24 7 min read A2Z Garage Doors
A customer called last Tuesday. Her heating bill had spiked, and she'd noticed cold air pouring around her garage door frame. The culprit wasn't the door itself, but worn weather stripping and seals that had cracked from years of Glenoma's damp winters. Replacing them cost far less than the energy she was losing monthly. Weather stripping and seals in Glenoma aren't glamorous, but they're one of the highest-return fixes you can make to your garage.
What Weather Stripping & Seals Actually Do
Your garage door has multiple seals working together. The bottom seal (or threshold) runs horizontally along the floor where the door meets concrete. Vertical side seals run the full height of the door frame. Top seals sit above the door opening. Together, they block drafts, moisture, and insects.
Think of them as the gasket on a refrigerator. Without a good seal, everything inside leaks out. In Glenoma's climate, where rain is frequent and temperatures drop hard in winter, a failing seal means your garage becomes an outdoor room. If you heat that space, you're paying to warm the neighborhood.
Signs Your Seals Need Replacement
Look for visible cracks, gaps, or hardening in the rubber. If you can slip a credit card between the door and frame easily, your seal is compromised. Check the bottom seal first.it takes the most abuse from impacts, debris, and moisture.
Cold drafts near the door in winter are the most obvious signal. Some homeowners also notice increased pest activity or water pooling after rain. A deteriorated bottom seal often leaves water stains on the concrete or damp spots inside the garage.

Choosing the Right Seal Material
Basic rubber seals are affordable and adequate for most homes. They last 5 to 7 years in Glenoma's wet climate. Premium silicone or EPDM rubber seals run 20 to 40 percent more but resist UV damage and stay flexible longer, often lasting 10 to 12 years.
If your garage gets direct afternoon sun or sits exposed to heavy rain, the premium option makes financial sense. If it's shaded and protected, standard rubber does the job. Either way, proper installation matters as much as material choice.
Maintenance Between Replacements
Clean seals quarterly. Glenoma's damp environment breeds mold and algae. A damp cloth and mild soap will extend seal life by years. Check for tears or gaps during your seasonal garage door maintenance routine. Catching small damage early prevents bigger problems.
