The Problem
Walk into most garages in West Bend and you're standing under a door that's older than the last remodel. Housing here went up mostly between 1958 and 1999, with the median build year landing around 1976. That means a lot of doors, tracks, and bottom seals installed decades ago on original hardware that was never built for the winters this area actually gets. The seal at the bottom of the door - the rubber strip that's supposed to press flat against the slab - hardens, cracks, and pulls away from the concrete over time. Once that happens, cold air doesn't sneak in, it pours in. Same goes for the weather stripping along the sides and top of the panel, where vinyl gets brittle and shrinks back from the jamb it's supposed to seal against. Owners usually notice it as a cold spot near the garage door, frost on the inside of the panel, or a draft they can feel standing a few feet back. It's rarely the opener and rarely the springs. It's the seal doing exactly what fifty-year-old rubber does.
The Common Mistake
The mistake we see most in West Bend is caulking or foam-spraying around a door instead of replacing the seal itself. It looks like a fix for a season, then the caulk cracks in the cold and you're back where you started, except now there's caulk stuck to the slab. The other common mistake is swapping in a generic seal strip without matching the track and threshold gap on that specific door - a lot of these older 1970s-era units have slightly different bottom astragal channels than what's sold off the shelf today, so a seal that doesn't seat right just curls and lets air through anyway within a month. On a house built in that mid-1970s window, the garage slab has often settled or sloped slightly too, which throws off how flush a stock seal sits. Skipping that check is how people end up replacing the same weather seal twice in one winter and assuming the door itself is the problem when it's the fit.
What the Weather Here Does to It
This area sits in a cold, severe climate band, and that's the whole reason seal failure shows up as often as it does. Rubber and vinyl don't fail from one bad night, they fail from the repeated swing - a stretch below freezing, a warm afternoon, back below freezing again - dozens of times a winter. That cycle is what makes a seal brittle years before it would wear out somewhere milder. On doors that trace back to the 1958-1999 building stock common across this area, the seal has usually already been through thirty or more of these freeze-thaw cycles before anyone thinks to check it. Once a seal cracks, cold air moving under a door doesn't just chill the garage - it pulls heat off any pipe or duct routed along that wall, which is its own separate problem in a climate this severe. The fix has to hold through that same cycle next winter, not just look sealed on install day.
