Most of the garage doors we find in Darien went up around 1957, and a lot of them are still the original door - a single, narrow wood panel or early steel slab sized for one car, not the wide two-car openings builders started pouring a decade later. These doors were hung on extension springs mounted along the horizontal track, not the torsion bar you'd see on anything built after the mid-1970s. That hardware is the whole story. Extension springs stretch and fatigue on a fixed schedule, and after sixty-some years most of what's left in these openings is well past any reasonable service life, patched instead of replaced because the door itself still looks fine. The fault shows up as a door that slams the last foot of travel, or won't lift past waist height without a shove - classic signs the spring tension has dropped off and the safety cable, if one was ever added, is doing more work than it should.
Darien sits about 4 miles from our Stamford shop, inside a service area where the median household income runs $183,112 and the broader housing stock dates to 1955-1984 - but Darien's own median build year, 1957, puts it at the early edge of that range. That matters here because the earlier the build, the more likely the door and track are original, not a 1970s or '80s replacement.
