The truck that comes out to Rowland Heights carries belt-drive and chain-drive opener units, rail kits, and the mounting brackets that fit the steel header framing common in homes built around 1976. That matters here because a lot of the original headers in this part of town were never built for today's heavier insulated doors, so a straight bolt-on swap isn't always possible - sometimes the bracket needs reinforcing before the opener goes up. We bring circuit boards, remotes, and keypads compatible with older chain-driven units, since plenty of houses out here are still running openers from their original build era. What we don't carry on the truck is specialty glass-panel door hardware or anything built for a commercial-grade door; that's a different job with a longer lead time on parts, and we'll tell you that up front rather than make you wait on a part that isn't coming.
