We stock standard torsion springs across the wire gauges common on steel sectional doors from the late 1980s through the 2000s, which covers most of what's installed in Hillsborough. Rollers, cables, and hinges in the common residential sizes ride on the truck, along with limit switches and circuit boards for the chain and belt-drive openers typical of that build period. What doesn't ride on the truck: specialty panel sections in discontinued colors, smart-opener upgrade kits, and anything custom-ordered for a non-standard door width. With median household income in Hillsborough at $98,467, well above the $77,799 average across our territory, we see more requests here for insulated panel upgrades and quieter belt-drive openers than straight like-for-like repairs - those are parts-order jobs, usually a few days out, not truck-stock items.
