Shenandoah sits about 3 miles from The Woodlands, and the houses here skew noticeably newer than the broader service area, where the median build year lands around 1988. Here, the typical home went up closer to 2002. That gap of a decade and a half matters more than it sounds. A door built in the early 2000s usually came with a steel opener bracket rated for heavier insulated panels, a safety-reversal sensor pair required by code at that point, and a torsion spring sized for a double-car door rather than the lighter single-spring setups common on older single-bay garages. We see fewer of the flat, non-insulated panel doors that show up on 1980s stock elsewhere in the area, and more sectional doors with foam cores that add weight the opener has to work against. When a spring goes on a 2002-era door, it's almost always a torsion spring under real load, not the stretch-style side springs you'd find on something built twenty years earlier. That changes what parts we bring and how we price the job before we ever get a look at it in person.
