Dunbar's houses went up around 1956 on average, about a decade ahead of the 1967 median we see across the wider Charleston service area. That gap matters more than it sounds. A house built in the mid-50s usually got its opener retrofitted later, sometimes twice, onto a header and bracket that were never sized for it. When we get a call from Dunbar, the first thing we check isn't the logic board - it's whether the mounting point the opener hangs from has loosened or cracked over sixty-plus years of vibration. We travel out from Charleston, about 6 miles, and we bring test units for the two or three motor types most common on homes this age. The fix itself is usually straightforward: swap the failed part, check travel limits, confirm the safety reverse still works. What takes the extra time here is confirming the bracket and header can actually hold the replacement, not just the old one that's already failing.
