San Carlos
San Carlos doors and what they need
San Carlos still has extension springs on many original doors, so spring repair here depends on which system the door runs. Converted single-car openings are where a door off its track tends to start.
Extension springs are a pair plus safety cables
The $200 starting price is for a torsion spring. Extension springs are their own row on the price list, from $225 for the pair, because they are a different job: both are replaced at once, each threaded with a containment cable so a future break stays on the cable instead of crossing the garage. Plenty of original San Carlos installs never had those cables at all, and adding them rides along with the spring work rather than being a separate visit.
Converted garages carry adapted hardware
A single-car opening widened in the 1980s usually got a door adapted to fit rather than specified for it, and adapted setups drift out of balance. When one of those comes off its track, the off-track repair, from $200, applies, and the visit includes finding out whether the setup underneath will just put it back on the same path. If it will, we say so and quote the correction before you commit to either.
Questions
Cost questions from San Carlos
What do extension springs cost to replace in San Carlos?
From $225 for the pair, installed, with the containment cables checked or replaced. A single torsion spring starts at $200. We list them separately because they are genuinely different jobs.
My San Carlos garage has no safety cables in the springs. What does adding them cost?
Fitted on their own they are one of the smallest visits we make, and fitted during spring work they fold into the job. Either way they are cheap insurance against a spring crossing the garage when it lets go.
Is converting extension springs to torsion worth the money?
On a door you plan to keep for years, often yes: torsion runs smoother and holds balance longer. The conversion price depends on the headroom and the shaft hardware your opening takes, so it comes from a look at the garage. We quote it next to a straight extension replacement and you compare the two numbers directly.
