Time on the Job
Most houses in San Anselmo went up around 1954, which puts this town ahead of the broader service area's median build year of 1966. That decade matters more than it sounds like it should. A door installed on a house built in 1954 has had roughly seventy years to accumulate rust on its hinges, stretch in its extension cables, and wear grooves into its rollers if nobody has ever swapped the hardware. We see a lot of original torsion springs on these homes still doing the job they were sized for in the Eisenhower administration, and a lot of them are one cold snap away from snapping mid-lift. The mild temperate climate here has been kind to the wood jambs and the paint, which is the only reason some of this hardware has lasted as long as it has. It hasn't been kind to the lubrication, which dries out the same everywhere. If your opener sounds like it's grinding gravel, or the door drifts an inch after you let go of the remote, that's original-era hardware telling you it's tired, not broken yet.
Booking a Visit
We run out of Petaluma, about 18 miles from San Anselmo, so we schedule the trip rather than dropping by on a whim. Tell us the age of the house and what the door is doing - grinding, drifting, refusing to close all the way - and we can usually tell you over the phone whether it sounds like a spring, a cable, or an opener gear before the truck ever leaves Petaluma. That saves everyone a wasted trip if it turns out to be something we don't handle. We'd rather ask a few questions up front than show up to the wrong job.
How It Shows Up
On a house this age, the failure usually announces itself the same handful of ways. The door slams the last six inches instead of settling, which means a spring has lost tension. It hangs crooked on one side, which points to a cable that's frayed or a drum that's worn unevenly. Or the opener runs but the door barely moves, which on original hardware is often a stripped gear inside a motor that's outlived its warranty by fifty years. None of these get better with time, and a spring under uneven tension is the one that can hurt someone. If you're hearing a bang followed by the door refusing to budge, stop trying it and call - that's a spring, and it's not a two-person lift job.
