For a standard-size replacement with a door we stock, removal and install usually happen in the same visit - the garage isn't open and unsecured overnight. The old door comes off, the new jambs and track go in, the door hangs, and the opener gets programmed to it before the crew leaves.
Where that timeline stretches is custom sizing or a special-order color or window pattern, which has its own lead time from the manufacturer before the crew ever shows up to install. That wait happens before the appointment, not during it - once we're on site, it's still a same-day job in most cases.
With roughly 13,448 households in Oakley, a meaningful share of them built within a few years of each other, we see clusters of these installs come through together - not because of any one event, but because doors and openers installed at the same time tend to wear out at the same time.
