New Garage Door Installation, Built for Corte Madera's 1960s Openings

Parts We Carry

Corte Madera's housing stock centers on 1960, which means a lot of garages here were framed for a single steel door on extension springs, not the wider double-car torsion setup that became standard later. We carry hardware for both: narrow single-door sections for original openings, wider insulated doubles for homes that have already been widened, and torsion conversion kits for owners moving off old extension springs. Given the area's median household income of $220,771 - well above the broader service area's $137,006 - we also stock more wood-look composite and full-view glass panel doors than a lower-income suburb would typically order, because that's what gets asked for here. We don't carry every manufacturer's full catalog on the truck; anything outside standard steel, composite, or aluminum-and-glass gets special-ordered, and that can add lead time. If you want a specific wood species or a custom color match, plan on waiting for the order rather than same-day install. The mild temperate climate band this area sits in means we're not building in heavy weatherstripping or insulation for extreme cold, but UV exposure on south-facing doors still matters over a few decades, so we talk through panel finish durability before you commit to a color.

Can You Do This Yourself

Swapping a garage door yourself is possible if the opening is standard and you're replacing like-for-like. Where it gets risky in Corte Madera specifically is the age of the framing: houses built around 1960 often have headers sized for the lighter single-layer doors of that era, and a modern insulated steel or composite door can weigh two to three times as much. Hanging that weight on old jamb hardware without checking the header first is how tracks pull loose within a year. Torsion spring work is also not a DIY job regardless of the house's age - the spring is under enough tension to cause serious injury, and if your home still has the original extension spring setup, converting it to torsion means new header-mounted hardware, which is carpentry and spring work at once. If your opening is unmodified and you're doing a direct swap with no structural change, a careful homeowner can manage it. Anything involving the header, the track width, or spring conversion is where we'd tell you to call rather than guess.

Why This Fails Locally

The failure pattern here traces straight back to the 1960 build date. Original single-car openings in this part of the county were framed narrow, and the header above them was sized for a light door - often under 100 pounds - on extension springs mounted along the horizontal track. Decades later, when an owner wants a modern insulated double door, that header isn't rated for the new weight, and the jamb studs weren't built to carry torsion spring tension at all. We've seen it show up as a door that lifts unevenly, a track that pulls away from the frame within the first year, or an opener that strains because the door itself is heavier than the unit was ever sized for. None of this is visible from the driveway - it only shows up once the new door's weight is actually hanging on the old structure. Houses that have already been remodeled with a widened opening and new header don't have this problem, but if your garage looks original from 1960, assume the structure behind the drywall is original too.

How We Fix It

We come from San Rafael, about three miles out, so we bring the full measuring kit and a range of header hardware on the first visit rather than guessing and coming back. Before any door goes in, we check the header's span and rating against the new door's actual weight - not the catalog average, the real weight of the model you've picked. If the header's undersized, we reinforce it or replace it before hanging anything, which is extra labor but it's the difference between a door that holds for years and one that sags in twelve months. Where a home is still running extension springs, we convert to torsion when the owner's moving to a heavier door, because torsion hardware is what actually handles that load safely over time. We balance the door to the opener afterward, not before, since a door that's out of balance will burn out an opener's motor regardless of how new the opener is. One limit worth being upfront about: if the header reinforcement needed is more extensive than a garage door job - structural work tied into the roofline - that's outside what we do, and we'll say so rather than take the job anyway.

Where This Job Goes Sideways

The most common surprise on a Corte Madera install is what's behind the trim once the old door comes off. A home built around 1960 that's never had the garage touched can have jamb studs that look fine from the front but are undersized or slightly rotted at the base where decades of runoff have sat against them. We can't see that until the old door and track are off, which means a quote based on a driveway look can change once we're into the opening. The other spot this goes sideways is sizing: an owner measures their own opening and orders online, then finds the door doesn't match the header clearance or the track depth available, and we're called in to make a door fit a rough opening it wasn't built for. With only 4,037 households in Corte Madera against roughly 134,170 across the territory we cover, the specific older hardware this housing era needs isn't something a supplier keeps on a shelf nearby - unusual spring sizes or discontinued track profiles sometimes mean a multi-day wait on parts, and we'd rather tell you that upfront than promise a timeline we can't hold.
