Seams and finish wear
On a door this age, you'll also see the panel seams separating slightly at the hinge points, or paint and wood finish failing unevenly across sections that have been replaced piecemeal over the years.
Los Altos Hills, Sunnyvale
Most Los Altos Hills garages went up around 1976, which means panel sizes and finishes that don't match today's stock doors. We match panels and replace full sections from our Sunnyvale shop.
On the truck
A house built around 1976 in Los Altos Hills usually has a door from that same era or a replacement installed sometime after - often a wood-look embossed steel panel or a solid raised-panel wood door, both common choices when this area was built out. The panel widths and rail spacing on doors from the mid-1970s don't always match what big-box suppliers stock today, so we carry a range of panel profiles and can special-order a matched section rather than forcing a mismatched one onto your door. We bring stock in the truck from Sunnyvale and order ahead for anything unusual, including wider panels sized for the larger single-family lots common in this area. If your door is original to a 1976-era build, tell us the brand stamp or model tag if it's still legible - it saves a trip.
Symptoms
The giveaway on a damaged panel is usually a dent or crack on the bottom two sections, where a car bumper or a stray ball does the damage, or warping along the top panel from decades of sun exposure.
On a door this age, you'll also see the panel seams separating slightly at the hinge points, or paint and wood finish failing unevenly across sections that have been replaced piecemeal over the years.
If only one panel is bent but the door still opens and closes true on the track, that's a panel job, not a full door replacement. If the whole door racks sideways when it moves, the problem is likely the track or hardware, not just the panel - worth mentioning before you call.
DIY or pro
Swapping a single panel sounds simple and sometimes is, especially on a door with exposed hinges and no torsion spring tension across that section. But doors from the 1976 era often use hardware that's been modified or re-hung at least once in close to 50 years, and mismatched screw patterns or stripped hinge holes turn a one-panel swap into a full day of improvising. We'll say plainly: if your door is a standard steel sectional and the panel is a common size, a confident DIYer can often do this safely with the door disconnected from the opener. If it's a custom wood door or anything with the spring still under tension, that's not a weekend project - leave the spring alone and call.
The repair
We start by confirming the panel section, not just the dent - matching width, rib profile, and finish, since doors from the 1976 construction wave in this area were rarely identical even on the same street.
Once we have the right panel in hand, we disconnect the opener, support the door, pull the damaged section's hinges and rollers, swap the panel, and re-hang hardware before testing balance and travel.
On a door with original or decades-old hinges, we'll usually recommend replacing those at the same time rather than reusing worn hardware on a new panel - mixing new steel against stretched hinge holes is how a panel loosens again within a year. We test the full cycle before we leave, not just the repaired section.
Watch-outs
Serving Sunnyvale, CA
The most common surprise on an older door is finding out the panel color or wood grain no longer matches once the new section is in place - finishes fade unevenly over decades, and we can't promise a seamless match on anything original to a mid-1970s install. Sometimes a panel that looked like the only damage turns out to be masking a bent track or sagging torsion hardware underneath, which means the job grows once we're inside it. We'll always call before expanding scope. And if a door built in that original 1976 window has enough wear across multiple panels, full replacement can end up cheaper than patching one section at a time - we'll tell you honestly which side of that line your door is on.
Questions
Often, yes. A lot of homes here went up around 1976, and we carry or can order panel profiles matching that era's common steel and wood-look styles. Exact color match on faded wood isn't guaranteed, but width and panel style usually can be matched closely enough that it isn't obvious from the street.
No, we run out of Sunnyvale, about 6 miles away, and bring parts and panels with us on the truck. We serve Los Altos Hills as part of our regular route, so we're not driving in cold for a single job.
Usually, if the rest of the door is sound and the hinges aren't stretched out. If your door is original to a 1976-era build and already showing wear on multiple panels, we'll tell you if a full door makes more financial sense than patching sections one at a time.
