The details
Southern New Hampshire winters are hard on springs and seals, and we keep doors running from Nashua to the Lakes Region. With long, hard winters with heavy snow loads, springs that break in sub-zero mornings is one of the most common calls we get.
Seals wear out faster in climates with real winters: rubber stiffens in the cold, gets torn by plowed snow and ice, and flattens over time. A new seal is one of the cheapest ways to make a garage warmer and drier.
If your floor dips or slopes, a threshold strip fills the gap a seal alone can't.
