Cos Cob's housing stock centers on a median build year of 1959, older than the wider service area's 1968 median. Garage openings from that era were often framed narrower than today's standard, and the track hardware bolted to the jamb may not match what current door lines ship with. We stock insulated steel doors in widths that cover the common single and double openings found on these mid-century houses, along with torsion spring systems rated for the heavier insulated sections. We don't carry every custom width or specialty wood-look panel off the truck - those get special-ordered, and that adds lead time we won't pretend away. For most Cos Cob openings, a standard-width insulated steel door with a new torsion spring and updated rollers is the right call, and it's what we keep on hand. If your opening is non-standard, we measure first and order second, not the other way around.
