Prices are parts plus labor. You get the exact figure in writing before we start. Alfonso Garage Door is a licensed and insured California contractor.
Wide doors, wider spring bills. San Mateo Park, Baywood and Aragon carry a lot of 16-foot doubles behind period homes. A 16-foot door is a two-spring counterbalance, so the honest starting figure there is the $320 to $560 pair, not the single-spring line.
Wood doors are still common. Carriage-style and solid wood doors weigh far more than a steel sectional, which means heavier springs, heavier hardware and a longer balance procedure. Where a wood door has swelled with winter damp, the fix is often a track and hardware job at the top of the range rather than a spring at the bottom.
Panel supply, not panel labor, sets the price. A single steel section is $250 to $800 installed, and the spread is almost entirely about whether the manufacturer still makes your profile. On discontinued profiles we price both a section and a full door in the same visit so the comparison is in front of you.
“Half the calls in San Mateo Park are 16-foot doubles. People price a single spring on the phone, then find out their door has two. I would rather say it up front.”
On a 16-foot double, a full spring and cable rebuild lands around $500 to $700, and a new insulated double is a different order of money. The rebuild is usually the right call unless the sections themselves are failing. Ranges for every service are on the San Francisco cost guide.

Yes, $250 to $800 for a single steel section installed, when the profile is still made. If it is discontinued we will price both options for you.
Yes. They need heavier springs and heavier hardware, and we spec them to the door’s actual weight rather than a chart.
