A garage door that starts closing and then reverses, or simply won't close no matter how many times you hit the button, is one of the most ignored problems in a Chester County garage. Homeowners get used to backing the car in, hitting the remote twice, or just leaving the door cracked a few inches because "it's been doing that for weeks." The trouble is that this isn't a minor annoyance that waits patiently for spring. Left open or unsecured through a snowy, icy winter, that garage becomes a wind tunnel for nor'easter gusts, a spot where pipes along the garage wall can freeze, and an easy opening for anything from stray animals to opportunistic break-ins during the holiday season when packages and gifts tend to pile up inside. A door that won't fully seal also lets road salt spray and melting snow track in, which speeds up rust on tracks, hinges, and the bottom of older steel doors common in this area's housing stock. None of that gets better on its own.
