We run out of Stamford, about 3 miles from Cos Cob, so there's no separate branch here and no reason to pretend there is. That short distance means a morning opener swap doesn't eat the whole day in drive time - we can usually get the old unit down and the new one tested before early afternoon.
We'll ask for the door's age and whether it's ever had a spring or cable replaced, because that tells us whether the opener install is a clean swap or whether we're also dealing with hardware that should've been replaced years ago. If your door was never matched to a torsion spring (common on original 1959 doors that got a panel replacement at some point but kept the old spring), we'll flag it before we quote the opener job, not after.
