Des Moines homes run older than the typical house across our service area. Regional housing here spans 1962 to 2005 with a median build year of 1983, but Des Moines itself centers closer to 1974 - a decade of construction that used lighter-gauge steel doors, smaller torsion springs rated for lower cycle counts, and openers with none of the safety-reversal sensors that became standard later. With roughly 12,066 households in the area and a median household income near $89,787, a fair share of these houses have never had the original door touched, which means original hardware still doing the job three, four decades on.
