Because installs here are scheduled from Columbia rather than from a local base, the best way to keep the date firm is to have the basics sorted before we show up: door size, whether you want insulated panels given our winters, and whether the opener is part of the job or staying as-is. With 2,055 households in Mount Pleasant and a housing stock centered on the early 1980s, a lot of openings are standard sizes, which keeps measuring simple, but older framing can still throw a surprise.
If your door is still working but rough - noisy, slow, or the remote is temperamental - that's a repair call, not an install, and it's worth starting there instead. We'd rather look at it first than sell you a door you don't need yet.
