Most of what we install replaces hardware that was never meant to last fifty-plus years. Shoreline's housing went up mostly between 1965 and 2001, with the bulk of it from the 1980s and 90s, so the openings we measure are standard sizes for that era - but the track and spring systems bolted into them are not what you'd spec today. We stock torsion springs rated for the cycle counts that match daily use in a household this size (median income here is $118,077, and most owners run two vehicles through that door, not one). We carry galvanized track sections, sealed ball-bearing rollers, and weather-stripped bottom seals built for a cold, damp climate rather than a dry one. We don't carry every niche opener brand - if you want a specific smart-home integration beyond the standard models we stock, we'll tell you that up front instead of ordering something we can't service later.
