On the truck for a Breckenridge maintenance stop we carry torsion springs sized for the standard 7-foot single and double doors common on houses from the early '60s, plus the rollers, hinges, and cable that wear out fastest on hardware that age. A lot of these doors run on side-mounted torsion setups that newer national door brands don't stock anymore, so we carry what actually fits instead of what's easiest to order.
We don't carry every proprietary opener part for every brand ever installed here - if your opener is an older or less common unit, we may need to order a specific gear or circuit board rather than swap it on the spot. That's the trade-off of a house this age: the door hardware is simple and we stock for it, but the opener electronics sometimes aren't.
Given the severe cold climate this area sits in, we also carry weatherstripping and bottom seals rated for that swing, since a cracked seal on a 1962 door frame lets in more cold than the door itself ever will.
