We stock belt-drive, chain-drive, and screw-drive opener heads, along with battery backup units, which matter more here than in milder parts of the country given the severe-cold band this whole service area sits in - a backup unit keeps the door working through a winter power blip instead of leaving a car trapped. We carry standard bracket kits to fit the older header clearances common in houses built in the 1960s and 70s, since a new opener doesn't always bolt straight onto hardware from that era without an adapter plate. What we don't carry on the truck is anything proprietary to a smart-home system tied to a builder's original install - if your house has a less common integrated system, we may need to order a matching part before we can finish the swap. We'd rather tell you that up front than start a job we can't close out the same day.
