Garage Door Tips, Fixes & Real Jobs from Contra Costa & Solano County

I'm Dustin Cantu, owner of Generational Garage Doors, based in Martinez, CA — I've done every job myself, on every truck, for 9+ years across Contra Costa and Solano County. This blog is where I write up what I actually get asked on driveways and phone calls: spring replacements, opener installs, insulation, maintenance, and the occasional unusual job — like converting a decades-old tilt-up wood door into a modern sectional door.

No filler, no recycled content — just what I've learned doing this work every day. New posts go up monthly. Browse what's below, or scroll down to watch a couple of real jobs in action.
