New Garage Door Installation for Larkspur Homes Built Around 1971

Parts We Carry

Most garages in Larkspur went up around 1971, and that year tells you a lot before we even see the door. Builders in that stretch were putting up single-layer steel doors on extension spring systems - two long springs running along the horizontal tracks, not the torsion bar you'd see on newer construction. A lot of those original openings are still standard sizes, which works in your favor: we carry new doors in the common widths that fit straight into a 1970s-era frame without reframing the opening. For insulation, Larkspur sits in a mild temperate band, so we're not pushing anyone toward the heaviest foam-core doors built for extreme cold or heat - a mid-weight insulated steel or a wood-composite door covers what the weather here actually asks of it. We stock torsion conversion hardware too, since a fair number of owners replacing an old extension-spring door want to move to torsion while they're at it - quieter, and the springs last longer under daily use. What we don't stock on the truck is custom-milled wood carriage doors; those get special-ordered and the lead time runs longer than a standard steel unit.

Can You Do This Yourself

Swapping an old single-layer door for a new insulated one on a 1971-era opening is mostly straightforward measuring and lifting - a two-person job if you're handy and the frame is square. Where it stops being a DIY project is the spring system. If your garage still has the original extension springs from that build era, converting to torsion means mounting a shaft, drums, and cable drums under real tension, and that's not a project to learn on a ladder. Even sticking with extension springs, a new door is heavier than the 1970s steel it's replacing in most cases, which means the spring sizing has to change too - guess wrong and the opener strains or the door won't hold position. If you're comfortable with track alignment, weatherseal, and hardware torque specs, the panel-and-track part is doable. The spring and cable work is where we'd tell you to call it in, same as we'd tell a neighbor.

How We Fix It

We come out from San Rafael, about 3 miles up the road, so there's no separate dispatch delay built into scheduling a Larkspur job. First stop is the opening itself - on a house from the early '70s we check whether the frame has settled or shifted over fifty-plus years, because that affects whether the new door needs shimming to sit flush. Then we size the door and spring system together: a new insulated steel door typically runs heavier than what came standard in 1971, so the torsion or extension spring gets matched to the actual installed weight, not the old one. We pull the original door, track, and hardware, set the new jamb brackets plumb, hang the new panels, and tension the springs to the door's real weight before we test full-cycle operation. Opener compatibility gets checked last - older openers sometimes need a new travel limit set for a thicker insulated door, and we handle that as part of the same visit rather than a callback.

Where This Job Goes Sideways

The most common surprise on a 1971-era Larkspur garage is the frame itself. Fifty years of settling can leave an opening slightly out of square, and a new door that looks like a drop-in replacement sometimes needs the jamb reset before it'll seal properly - that adds labor time nobody budgeted for. Another spot: owners who want to keep the original opener because it still runs fine. Older openers paired with a new, heavier insulated door sometimes can't lift it reliably, and we'll say so rather than install a door that strains the opener every time it opens. One honest limit on our end - if the opening itself needs structural framing work, not just hardware, that's outside what a garage door installation covers, and we'll point you to someone who handles that part before we come back to finish the door.
