The DIY Question
The question we get most from this neighborhood isn't whether to replace a door, it's whether a homeowner can order one online and hang it themselves. For a lot of houses, the honest answer is no, and it's not about the door panel itself. It's about what's behind it.
Most houses in Lucas Valley-Marinwood went up around 1963, right in the middle of the build window that runs from 1938 to 1996 across this part of the service area. That means original framing, original header heights, and in a lot of cases an opening that was never squared to modern track tolerances. A new door kit assumes a stock 7-foot opening with plumb jambs. A house built in the early '60s doesn't always give you that. Get the measurement wrong by half an inch on one side and the new door binds on the track before the opener ever gets bolted in.
We're not saying don't try. We're saying measure the opening, top, middle, bottom, both sides, before you order anything, and if the numbers don't match on all four points, that's the sign this isn't a weekend kit job.
The Complications
The complication we run into most in this pocket of the service area is jamb condition, not door style. Framing from the early 1960s used dimensional lumber that's shrunk and settled over sixty years, so the rough opening on a lot of these garages is out of square by more than the quarter-inch a new door frame can absorb.
The mild coastal climate band this area sits in is actually a point in your favor here, we're not fighting the rust and warp problems that install crews deal with in freeze-thaw regions, so the wood itself is usually sound even where it's shifted. That means the fix is almost always shimming and re-framing the jamb, not replacing it outright.
The other thing that comes up: older garages sometimes have a single incoming circuit shared with something else in the house, which matters once you're running a new opener. We check that before we quote, not after.
What the Repair Takes
An install starts with pulling the old door and track off the opening and inspecting the jamb and header for square, level, and rot, the last one being rare here given the mild climate, but we still check. If the framing's out, we shim it to true before anything new goes in; skip this step and the new door will bind on one side within a year.
From there it's new track, new hardware sized to the door weight and width, weatherstripping at the jamb and floor, and the opener mount, if you're replacing that too. We test the balance with the door disconnected from the opener first, a properly balanced door should hold at any point when lifted by hand. If it doesn't, the spring tension gets adjusted before we ever power up the opener and call it done.
What It Costs
We don't post a flat number for installs here because the jamb work we described above changes the job. A clean opening with square framing is a different quote than one that needs re-framing before the door goes in, and given the age of the housing stock in this area, we see both.
What we can tell you: the quote is free, it's based on what we find at your opening, not a phone estimate, and it covers the door, track, hardware, and labor as one number, not add-ons discovered halfway through. If you want a number before we're on site, the most useful thing you can give us is the rough opening measurement and whether you're keeping or replacing the opener.
How Long It Takes
A straightforward swap, same opening, sound jamb, opener staying, is usually a single-day job. Add jamb re-framing, which is common enough in this age of housing stock that we plan for it, and you're looking at extra time on site for the framing work before the door itself goes in.
We travel from Novato, about 3 miles out, so scheduling isn't the bottleneck, it's whatever the opening needs once we're there. We'd rather tell you it's a two-visit job up front than rush a re-frame to hit a one-day promise.
What Is on the Truck
For installs in this area we carry standard-width track and hardware sized for the door widths common in 1960s single and double garages, plus the shims and jamb stock we use often enough here that we don't want to be driving back to Novato mid-job for them.
What we don't carry as stock: custom wood door panels or oversized openings outside standard dimensions. If your house has one of those, we'll confirm the order before the install date rather than show up and find out on site. That's the one limitation worth knowing going in, everything else on a standard install, we bring with us.

Questions, answered
Do you install garage doors in Lucas Valley-Marinwood, or just repair them?
We do full installs here, traveling from our Novato location about 3 miles away. It's the same crew and truck stock as our repair calls, installation isn't a separate branch or a different service area, just a different scope of work on the same job.
Why does my 1960s garage opening not fit a standard door kit?
Framing from that era has settled over sixty years, so the rough opening is often out of square by more than a new door frame can absorb without shimming. It's common enough in houses built around 1963 that we check jamb square before quoting, not after we've already ordered the door.
Will the mild climate here affect my new door or opener?
Less than you'd think in a harsher climate, no freeze-thaw cracking, less warp on wood jambs. The bigger factor for houses here is the age of the framing itself, not weather exposure, which is why we spend more time on jamb condition than on weatherproofing.
