A dented or cracked section rarely means buying a whole new door. If your door model is still in production, Alfonso orders the matching panel, swaps it, and aligns it to its neighbors — typically from $250 per section installed in San Francisco. When panels are discontinued, we'll price both a new section and a new door so you can compare.
| Job | Starting price |
|---|---|
| Single steel section, supplied and installed | from $250 |
| Two or more sections | from $550 |
| New single-car door if panels are unavailable | from $1,200 |
Starting prices for San Francisco and the Bay Area, parts and labor, last updated July 2026. What can raise the price: two springs instead of one, a heavy, insulated, wood or oversized door, worn cables, rollers or drums we find on the visit, or a part we have to order.

This is one of the most difficult and dangerous repairs. We strongly recommend you do not attempt it.
INSPECT: You can safely look at the damage.
GET INFO: Take photos of the damage. Write down the manufacturer name or model number, often found on a sticker on the side of the door.
⚠️ This is not a simple DIY project:
Structural Integrity: The panels are the door’s main structure. Removing one without proper support can cause the entire door to sag or collapse.
High-Tension Components: The bottom panel is connected to the lift cables and high-tension springs. Trying to remove this panel yourself is extremely dangerous.
Extreme Weight: Panels are large, heavy, and very awkward to handle.
The Matching Problem: Sourcing the exact matching panel is the hardest part. It must match the color, style, insulation, and even the model year. A professional has the supplier relationships to do this.

If the dents are only part of the story and the whole door looks tired, read upgrading an old garage door for instant curb appeal.
A single steel section starts at $250 installed. The exact price depends on the door's size, insulation level, and how the panel has to be sourced. Multiple sections start at $550. Once damage spreads past two sections on an older door, a new door often costs about the same and resets the whole system's age — we'll show you both numbers.
Not at first. A factory-fresh panel next to a door that's spent fifteen years in coastal sun and salt air will read slightly brighter. The gap fades noticeably within a season as the new panel weathers. Where the mismatch would be stark, we'll tell you before ordering — sometimes a repaint of the full door or a different approach serves you better.
Depends where the hit landed. A cosmetic dent in the panel face is usually fine to operate. A crease at a hinge line or panel edge is not — the door flexes at every joint as it curves through the track, and a compromised section can fold. We can assess it quickly, brace it if needed, and keep the door usable while the replacement section ships.
Often yes, and it's a common request in the older Sunset and Richmond housing stock where wood doors meet decades of fog. Bottom sections rot first because they sit in splash and seal contact. We can fabricate or source a matching wood section, and we'll also fix the drainage or seal problem that rotted it — otherwise the new panel goes the same way.
In-production panels from major manufacturers typically arrive in one to two weeks; the installation itself takes two to four hours including hinge transfer, alignment, and a balance check, since a new section changes the door's weight slightly. Discontinued panels are the wildcard — we'll know within a couple of days whether one can be sourced.
