About Porter's Repair
Family owned. Napa Valley rooted. Honest work since day one.
Our Story
30+ Years of Keeping Napa Valley Moving
Porter's Repair was built on a simple idea: treat every customer the way you'd want to be treated. Mark Porter started the shop with a set of tools, a lifetime of mechanical knowledge, and a commitment to honest, quality work — and that hasn't changed.
For over 30 years, we've been the shop that Calistoga and the greater Napa Valley community turns to when something goes wrong. From daily drivers to farm tractors, we've seen it all — and we fix it right the first time.
We're not a chain. We don't upsell you on parts you don't need. We tell you what's wrong, what it'll cost, and we get it done. That's the Porter's way.
Honest Estimates
We tell you what's wrong and what it costs — upfront, no surprises. Free estimates on every job.
Quality Work
We don't cut corners. Every repair is done right, with quality parts and the care your vehicle deserves.
Community First
We live and work here in the Napa Valley. Our reputation is built on the trust of our neighbors, and we take that seriously.
