The housing across Sugar Land's service area mostly went up between 1976 and 2015, with the median build year sitting around 1995 - most of it that 1980s and 90s stock you'll find repeated across the 23 named areas we work, from Telfair a mile out to Pecan Grove six miles south. That matters because torsion springs have a rated life measured in door cycles, not years, and a spring installed when the house was built is now three to four decades into a job it was never meant to do forever.
The moderate-heat climate band here adds a second layer. Garages in this part of Texas run hot for long stretches, and heat dries out the lubricant on torsion springs and cracks aging nylon rollers faster than it would in a cooler climate. Combine original-to-the-house hardware with that heat cycle and you get the pattern we actually see on calls: springs and rollers failing in the same decade of a house's life, across the same subdivisions, within a few months of each other during the hottest stretch of the year.
