We stock torsion springs in the sizes that match 1960s-70s residential doors, along with standard rollers, cables, and center bearings - the parts that fail most often in housing from this era. What we don't always carry on the truck: panels or sections for doors that were custom-ordered decades ago, since manufacturers don't keep every old profile in production. If your door needs a specific obsolete panel, that's a lead-time item, not a same-visit fix, and we'll tell you that honestly instead of promising a part we don't have. For openers, we carry common gear kits and circuit boards that cover most of what fails in older drivetrains. The short drive from Stamford means we can come back quickly once a special-order part arrives - we just can't pretend every part for a 55-year-old door is sitting on the shelf, because it usually isn't.
