Florence is older than most of the territory we cover out of Georgetown. The typical house here went up around 1975, well ahead of the broader service area's median of 1993. That puts a lot of Florence garage doors into their third or fourth decade of hardware, sometimes with replacement panels bolted onto original tracks and brackets that were never meant to be mixed and matched.
It's a small area by household count - about 423 homes - so you won't find a big-box contractor with a local crew here. What you get instead is a lot of variety: some houses have had a full door-and-opener swap at some point, others are still running whatever came with the place in the 70s. We see both on the same street.
