Spring Repair for Tamalpais-Homestead Valley Doors

Parts We Carry

We carry torsion and extension springs in the sizes that cover most doors going back to the 1960s, which is when most of the housing stock out here went up. That means standard torsion springs on steel shafts, extension springs with safety cables for the older side-room setups, and the end bearing plates and cable drums that wear out alongside them. The mild temperate climate on this side of the county is kind to steel - you don't get the rust-through failures we see in wetter, colder regions - but galvanized coating doesn't stop a spring from reaching the end of its cycle count. We stock the common wire gauges and wind directions on the truck. What we don't stock is the oddball stuff: custom-length springs for a door that's been shimmed or rebuilt off-spec, or parts for an opener model that's been out of production for twenty years. Those get special-ordered, and that adds a day or two, sometimes more depending on the manufacturer.

Why This Fails Locally

A door installed when a house here was built in 1963 is running torsion hardware that predates the safety standards common today - no containment cable, single spring on a double door, sometimes a center bracket that's been patched rather than replaced. That matters because a 1960s build means the spring in your garage has likely been replaced once or twice already by whoever owned the house before you, often with a universal spring that's close enough in size but wrong in cycle rating. Close enough works for a while. Then it snaps early, usually on a cold morning or after a stretch of heavy use, and the owner is standing in the driveway wondering why a 'new-ish' spring just failed. The age of the housing stock here is the reason this keeps happening - it's not bad luck, it's hardware reaching the end of a life that was shorter than advertised.

Getting It Booked In

We run this job from San Rafael, about 7 miles out, so there's no branch or depot in Tamalpais-Homestead Valley to swing by on a whim. When you call, we ask for the door's width, whether it's one spring or two, and roughly how old the opener is - that lets us load the right spring before the truck leaves. Skipping that step means a wasted trip and a second drive back out. If you can send a photo of the spring and the torsion tube, even better - it cuts the guesswork down to almost nothing. We don't promise a same-day window from here; the drive factors into how the day gets scheduled, and we'd rather tell you that straight than promise something we can't hold to.

Time on the Job

Once the truck is on-site, a standard torsion spring swap on a single door runs under an hour in most cases - the bulk of the time is winding the new spring to the correct tension and checking the balance point, not the part swap itself. A double door with two springs takes a bit longer, and if the bearing plate or cable drums are also shot, add time for those. The part that doesn't show up in the on-site number is the 7 miles each way - if you're comparing our quoted job time to a shop that has a branch three streets over, remember the clock on our end includes getting out to you.

The Cost of This Job

We don't post a flat number here because spring jobs vary more than people expect - one spring versus two, standard wind versus high-cycle, whether the drums or bearings need to come out too. What we can tell you is that houses from the 1960s era common to this area often need more than 'just the spring' because the rest of the hardware has been sitting under tension for decades without being touched. A technician will give you the actual number on site, broken out by part, before any work starts. If a quote looks suspiciously low over the phone without anyone seeing the door, that's usually because it's missing something.

Where This Job Goes Sideways

The most common mistake we see corrected after the fact: a spring that's the right length but the wrong cycle rating, installed as a quick fix years ago, now failing again sooner than it should. The second: extension springs installed without safety cables, which is a real hazard if one lets go. We won't leave a job without the cables in place, even if that wasn't part of the original call. And here's the honest limit - if your opener is old enough that replacement parts are genuinely unavailable, we'll tell you that a spring fix isn't worth doing in isolation, and that the opener itself is the better money. Those are judgment calls made at the door, not over the phone.
