Real repair guides, maintenance advice, and what we're seeing out on the road across Katy and greater Houston.
Real fixes from a real driveway mechanic. I’m Scott, owner and only mechanic at On The Move Mobile Mechanic. I come to you anywhere in Katy, Cinco Ranch, Fulshear, Cypress and the greater Houston area. Every article here comes from problems I actually diagnose in customers’ driveways and parking lots: cars that won’t start, batteries that die overnight, failing alternators and starters, brakes, oil changes, tune-ups, and the extra beating Houston heat puts on a car.
My goal is to help you figure out what’s going on before you spend money. Some posts walk you through a quick check you can do yourself, like testing an alternator or telling a dead battery from a bad starter. Others explain what a proper diagnosis looks like, and when it makes sense to have a mechanic come to you instead of paying for a tow. I work labor-only, so after I diagnose the problem you can buy the parts wherever you like. If you’d rather have it looked at in person, call or text 346-717-6593.
