Garage door installation in Altadena usually means fitting a new door to an opening that was never standard to begin with. The neighborhoods up against the San Gabriels are full of detached garages built between the 1920s and 1950s, many now used as workshops or studios, and a surprising number have settled out of square or carry door sizes no modern catalog lists as stock. When you call Stonegate Garage Door Repair at (844) 972-4229, the job starts with measuring what is actually there, not assuming the rough opening matches the old door that is hanging in it. We handle the full system, mechanical and motorized, so one visit covers panels, tracks, springs, and the opener.
Why Altadena Homes Are Different
Altadena’s housing stock does most of the explaining. The streets around Lake Avenue and up toward Christmas Tree Lane are lined with California bungalows, Craftsman cottages, and mid-century ranches, and many of their garages were built as separate wood structures rather than attached boxes. Decades of dry Santa Ana winds and intense sun bake south- and west-facing wood doors until paint fails in sheets. Seasonal canyon winds flex older doors, and winter rain finds every crack a finish once sealed. The result is that doors here do not age gracefully. They warp. The hardware loosens. And because so many garages now hold a home office, a kiln, or an ADU tenant rather than a car, a door that refuses to close is an urgent problem for more than just the family sedan.
Terrain matters too. Sloped lots along the foothill streets mean many garage floors drain toward the door, which accelerates rot in wood jambs and rust in track brackets. We regularly see original hardware still in place on 1940s carriage doors, repaired over the years with whatever bracket happened to fit. That kind of patchwork history means a replacement door often starts with rebuilding the opening itself, not just hanging a new panel on old framing. If you live in the 91001 or 91003 ZIP codes, you likely already know this from watching your own door fight its frame. Our job is to make the door and the opening agree again.

Our Main Altadena Services
Most calls from Altadena start with one of two problems: a door that will not go up, or an opener that runs but will not move the door. Stonegate Garage Door Repair sends technicians who already know the older hardware common in these foothill garages, so diagnosis moves faster and the fix is aimed at the actual failure.
Garage Door Repair in Altadena
When an Altadena garage door stops mid-travel or drops hard to the ground, the cause is usually a broken spring, a snapped cable, or a track that has pulled away from a shifting wood frame. Older detached garages with single-spring hardware put more stress on every component, and a door that has been patched for decades often has a mix of parts that never quite matched. We inspect the whole system rather than just swapping the part that failed, because a second failure is often already underway two feet away. For a full walkthrough of what door repair covers and what it costs here, see our dedicated Garage Door Repair in Altadena page.
Garage Door Opener Repair in Altadena
Altadena garages converted to studios and ADUs put a lot of faith in the opener, because that door may now be the main entrance to a living space. A LiftMaster or Craftsman opener mounted on a 1950s beam can work fine for years and then start running without moving the door, usually because the carriage, limit settings, or photo eyes have fallen out of adjustment. We cover the brands homeowners actually have here, diagnosing the motor and the door together since one often misbehaves because of the other.

Garage Door Installation in Altadena
New door installation in Altadena is rarely a straightforward swap. Homes here run heavily to 1920s-1950s construction with detached garages that were framed by hand, and many openings are no longer square after decades of settling and hillside drainage. A new door often needs a rebuilt threshold, new jambs, or low-headroom track before it can swing true. That changes the job from a simple hardware mount into a custom fit, which is exactly where our experience with older openings and non-standard sizes matters. Garage Door Installation starts with measuring the opening itself, then matching a door and track system that will actually work in that space.
Garage Door Replacement
Signs you need it
A door with cracked panels, a rotting wood frame, or rusted-through steel sections has reached a point where replacement costs less than repeated repairs.
What it costs in Altadena
A full new door installation in Altadena typically runs $700 to $2,200 depending on door size, material, and the condition of the existing opening.
How we do it
We remove the old door and its hardware, check the opening for square and level, repair or reframe where needed, then install the new door, track, springs, and weather seal as one matched system.
Garage Door Installation Service
Signs you need it
When an Altadena garage has been converted to a workshop or ADU and the old door cannot hold a seal against wind and dust, a properly installed new door restores both security and comfort inside the space.
What it costs in Altadena
Standard installation labor for a single door is typically part of the $700 to $2,200 installed range, with the final figure set by the written estimate before work begins.
How we do it
We confirm the rough opening dimensions, select track and spring configuration for the available headroom, then install the door sections, hardware, and any new opener or seal the job requires.
Garage Door Seal Installation
Signs you need it
Daylight under the door, dust blown in by Santa Ana winds, or water pooling at the threshold after winter rain all point to a failed bottom seal or side weatherstrip.
What it costs in Altadena
Seal replacement is a focused job and is typically quoted as part of a larger repair or installation, not as a standalone project with its own price band.
How we do it
We inspect the door for level, replace the bottom and side seals with material sized to Altadena’s older wood doors, and test the door’s travel to confirm a tight close.
What Garage Door Installation Costs in Altadena
| Item | Typical range in Altadena |
|---|---|
| New door installation (full system) | $700 – $2,200 |
| Opener installation | $250 – $550 |
| Panel replacement | $250 – $500 |
How long does garage door installation take in Altadena?
Most single-door installations are completed in one day, but an opening that needs reframing or custom track work can extend the job. The written estimate lays out the timeline before any work starts.
Will my older Altadena garage need extra work before a new door?
Often, yes. Out-of-square openings, low headroom, and settled wood jambs on 1920s-1950s garages frequently require reframing or new track mounting before a new door installs correctly. The estimate accounts for that up front.

What Altadena Customers Say
"Track was bent and two of the rollers were shot. He straightened what he could, swapped the rollers for nylon ones, lubricated everything, and had it done in about an hour."
- Heather Miller"Fixed the spring properly and the door works fine. He did leave the old spring and some hardware by the side of the house, and I had to text to ask about hauling it off. They came back for it, just took a couple of days."
- Bryce Rhodes"Door installed in about four hours, old one hauled away, and he stayed to program both cars and the wall panel before he left."
