Mashore Autobody: honest body work from a family shop in Brentwood
Family owned since 2006. Free estimates, and we work for you, not your insurance company.
Serving Brentwood, Oakley, Antioch, Discovery Bay and Byron.
Why Mashore Autobody
We work for you, not your insurance company.
We are not contracted with any insurance company, on purpose. When a shop is contracted with an insurer, the insurer becomes its customer. We want you to be ours. We work with every insurance company, we send your claim to yours, and the choice of shop stays yours.
Who we are
Family owned since 2006
Steve Mashore started Mashore Autobody in 2006 with one rented bay at this location. The 2008 crash made it hard, and he kept believing that good work and treating people right would carry the shop. Today the shop owns the building, and Steve's son Casey manages much of the day-to-day work.
Most of our customers find us through friends and family. We would like to meet more of you.
