Steel panel replacement for Bonita's mid-1970s garage doors, done by a crew that drives 12 miles from San Diego with the right hardware loaded before the truck leaves.
Bonita sits about 12 miles from San Diego, and that drive changes how a panel job actually runs here. We're not sending a truck across town for a five-minute look - we load the hardware for the job before we leave, because a second trip out to this side of the county costs the whole afternoon. That means figuring out the panel size, the hinge spacing, and whether the door is torsion or extension spring before the truck ever leaves the yard.
Most houses in Bonita went up between 1967 and 1992, with the median right around 1975, which puts a lot of doors here in steel sectional territory - flat or lightly ribbed panels on hardware that's changed more than once since these houses were built. We pull the damaged section, match the panel width and the color as close as the manufacturer's current line lets us, and reset the hinges and rollers on that section so the whole door tracks evenly again, not just the piece we swapped.
We don't guess at panel sizing over the phone. On a mid-70s door, panel heights and rail spacing vary enough between manufacturers that a wrong guess means a second drive out here, and we'd rather get it right the first time than promise a same-day fix we can't back up.
What It Costs
We're not going to put a number here that we can't stand behind for your specific door - panel cost depends on the width, whether the color needs custom matching, and whether one panel got hit or three. What we can tell you is how the decision usually breaks in a neighborhood like this one.
Bonita's median household income runs around $117,750, close to but a bit under the $118,431 figure for the wider San Diego service area we work. That gap doesn't change what a panel costs to replace, but it does show up in which owners fix one section and which ones decide, once we're already out there, to replace the whole door instead. On an older steel door, replacing one panel on a door that's already dented in two other spots is often money spent twice.
The honest limit here: if your door is old enough that the manufacturer's discontinued that panel profile, we may not be able to match it exactly, and we'll tell you that up front rather than order something that won't sit flush.
Doing It Yourself
A single dented panel on a steel sectional door is one of the more DIY-friendly garage door repairs, if you can find the right part. That's the catch in a place like Bonita: with a median build year around 1975, a fair number of these doors are old enough that the exact panel profile isn't sitting on a shelf anywhere close by. You may end up ordering from the manufacturer directly, and lead time on an obsolete profile can run longer than the repair itself.
If you do go after it yourself, the panel swap is usually the easy part - unbolt the hinges, slide the section out, slide the new one in, rebolt. Where people get hurt is the spring. If the dent is on the bottom panel and the door won't balance right afterward, don't start loosening anything near a torsion spring under tension. That's not a panel problem anymore, that's a spring problem, and it's the one part of this job where a mistake breaks bones, not just doors.
We'd rather you call for the tricky matching or the spring work and handle the easy bolt-and-swap yourself if you're comfortable with it. There's no reason to pay a truck's worth of labor for a job a homeowner with a socket set can do in twenty minutes.
How It Shows Up
On the doors we see out this way, panel damage tends to fall into two buckets. The first is a straight dent - a bumper, a bike, a trailer hitch clipping the bottom panel - which is a clean single-panel swap on most of these mid-70s steel doors. The second is sun and time: paint chalking, seam gaps opening up where the panel's been flexing on original hardware for decades, and hairline cracks along the ribbing on doors that have never been touched since they went up.
The mild temperate climate here means we're rarely dealing with rot or rust-through the way you would in a wetter region - the failures are mechanical and cosmetic, not structural decay. That's actually good news for panel-only repairs, since the frame and rail underneath are usually still sound even when the visible panel looks rough.
What we watch for on a house this age is whether one bad panel is really a symptom of a door that's due for full replacement - worn rollers, a track that's slightly bowed, hinges stripped from forty-plus years of cycling. If that's what we find, we'll say so before we start bolting on a new panel that's better than the rest of the door.

Can you match the panel color on an older Bonita door exactly?
We match as close as the manufacturer's current stock allows, but on a door built in the 1970s, factory paint runs have shifted over the decades. Expect a close match, not always a perfect one, especially on doors that have faded unevenly in the sun over the years.
How long does a single panel swap take once you're on site?
Once we've confirmed the panel size and it's in the truck, the swap itself is usually quick. The variable is finding the right part for older, discontinued profiles common on 1970s-era doors - that step happens before we drive out, not after.
Is it worth replacing one panel on a 45-year-old door?
Sometimes yes, sometimes no. If the rest of the door and hardware is sound, a single panel swap is the cheaper fix. If the door's already showing wear elsewhere, we'll tell you honestly when a full replacement makes more sense than patching one section.
