Do you come to my site?
Yes. We're mobile and in-shop. We come to you anywhere in the San Francisco Bay Area. Your machine doesn't move when it's down, so we bring the shop to it.
What areas do you cover?
San Jose, Fremont, Oakland, Livermore, Stockton and the surrounding areas, out toward the Central Valley. If you're near there, call and we'll tell you straight.
What equipment and brands do you work on?
Dozers, loaders, excavators, backhoes, motor graders, skid steers and on-highway diesel trucks. We service Caterpillar, Peterbilt, Kenworth, John Deere, Cummins, Detroit Diesel, Case IH, New Holland, Hino, Claas and Bobcat. We're dealer-trained with a Caterpillar background and 20+ years combined experience.
Mobile or in-shop — which do I get?
Both. A lot of work we handle right where the machine sits. Bigger jobs come into the shop. Tell us what's down and we'll tell you which makes sense.
How do I get a quote?
Call or text (925) 858-8630, Mon–Fri, 7am–5pm. We diagnose honestly — no phantom rebuilds, and we won't upsell you a rebuild when it's a $30 sensor.
