A garage door that's been grinding, sagging, or slow to close all summer doesn't fix itself over the dry months. It gets worse. Add a few weeks of winter rain, a swollen wood frame, or a spring that's been one hard-close away from snapping, and that small annoyance turns into a door that won't open at all, or one that comes down fast and unannounced. Choosing the right company before that happens is cheaper and safer than choosing one in a panic after it does.
