How far out is Mount Prospect from your shop?
About three miles from our base in Des Plaines. We don't keep a branch or depot in Mount Prospect itself - we drive out for every job, including routine maintenance visits.
Doing It Yourself
You can do real maintenance yourself on a door this age: wipe down and lightly oil the rollers and hinges, check that the photo-eye sensors near the floor are aligned and clean, and look at the bottom seal for cracking before cold weather sets in. What you shouldn't touch is the spring. On houses from the late 1960s and 1970s we still find extension springs running along the horizontal track rather than a torsion bar over the header - older hardware that stores a lot of force and lets go without warning if a cable frays. If your door has that setup, leave spring work to someone who does it daily. One honest limit here: if the track is bent or the jamb has shifted with the house settling, no amount of lubrication fixes that, and we'll tell you it's a track or structural repair, not a maintenance visit.
How It Shows Up
With the climate here running cold through winter, the failures we see on 1960s and '70s stock follow a pattern. Steel panels from that era are thinner-gauge than what's sold now, so they dent and then don't seal flush, letting cold air push the bottom seal loose. Wood doors from the same period swell in damp fall weather and bind in the track, which strains the opener and the rollers it's dragging. Openers installed as upgrades in the 1980s and '90s are now reaching the end of their working life, and when the gears inside wear down, the door starts reversing partway up or drops faster than it should. None of that is unique to one house - it's what a fifty-plus-year-old door, built for that generation's hardware standards, does under repeated freeze-thaw cycles.
