From the business
In the shop's own words: “Meet Bay City Welding”
Bay City Welding is a mobile welding service based in San Francisco, run out of a small shop by Mark. Whether you need a quick fix on the road or a job scheduled in advance, we bring the same care and craft to every project.
We've cut bed frame legs on a Sunday afternoon, fixed a motorcycle kickstand within the hour for a rider passing through from San Diego, and welded a car's a-arm the same day it broke down. When other shops don't pick up the phone, we do.
We show up on time, quote a fair price, and do the job right the first time. If you need a welder in San Francisco, call and talk to Mark directly.
- Owner-operated by Mark
- On-site or in-shop repairs
- Same-day and weekend availability
- Fair, upfront pricing
