Questions People Ask Before They Call
Hours, warranty, rides, prices, and what "onsite" actually means. If yours is not here, call (781) 438-3838 and ask.
Hours, Warranty, Rides, and the Name
What are your hours?
Monday through Friday, 8:00 AM - 5:00 PM. We are closed Saturday and Sunday. There is an after-hours key drop at the shop, so you can leave the car the night before and we start on it first thing.
Do you come to my house or office? Is Onsite a mobile mechanic?
No. The name means the work happens on site, in our own bays at 30 Pine St Middle Unit, Stoneham, MA 02180, with our own ASE Master-certified technicians. Nothing is subcontracted out and marked up. Alignment, diagnostics, transmission work, and brake jobs all happen under one roof.
Do your repairs come with a warranty?
Yes. Every repair is covered by a written 12-month / 12,000-mile warranty on parts and labor, whichever comes first. We use OEM or OEM-equivalent parts.
Do you have loaner cars or a shuttle?
We do not keep a loaner fleet. We offer early drop-off, after-hours key drop, and a short-range local shuttle in the Stoneham area. Most routine work (oil changes, brakes, alignments) is done the same day, so most customers do not need a car in between. If a repair will take several days, we tell you before you commit.
Do I need an appointment?
Walk-ins are welcome, and most routine work is done the same day. Booking online or calling (781) 438-3838 gets you a bay faster, especially for bigger jobs. If a repair will take more than a day, we tell you when we give you the estimate.
How much will my repair cost?
You get a free written estimate before any work begins, and we only recommend what the car actually needs. Every service page on this site lists a typical price range. A diagnostic visit runs about $100 to $160, and that fee is applied to the repair if you have us do the work.
Will using an independent shop void my factory warranty?
No. Under the federal Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty because you had maintenance or repairs done at an independent shop. We document every job so your service record stays complete.
Which towns do you serve?
Most of our customers come from within about 15 miles of the shop: Stoneham, Woburn, Winchester, Wakefield, Melrose, Medford, Malden, Reading, North Reading, Lynnfield, Saugus, Burlington, Arlington, Lexington, Somerville, Cambridge, Everett, Revere, and Boston. The shop is at 30 Pine St Middle Unit, Stoneham, MA 02180, just off Route 93 and Route 28.
Do you do Massachusetts state inspections?
We do not issue inspection stickers. We do the part that decides whether a car passes: a pre-inspection check of brakes, tires, lights, wipers, exhaust, and steering, and the repairs after a rejection. If your check engine light is on, we diagnose and fix the cause so the emissions test will pass.
About the Work
What auto repair services do you offer in Stoneham, MA?
Brake repair, engine repair, transmission service, A/C repair, exhaust repair, wheel alignment, suspension and steering, electrical diagnostics, oil changes, and timing belt replacement. All work is done by ASE Master-certified technicians on all makes and models.
How much does auto repair cost at Onsite Automotive?
Every job is priced on the parts and labor it actually needs. We give you a free written estimate before starting, and we never upsell. For reference: an oil change runs about $50 to $120, a four-wheel alignment $100 to $180, and brake pads and rotors $250 to $700 per axle. Call (781) 438-3838 for a quote on your car.
Do you service all makes and models?
Yes. We service every domestic brand (Ford, Chevrolet, GMC, Jeep, Dodge, Ram, Chrysler, Cadillac, Buick, Lincoln) and import brand (Toyota, Honda, Subaru, Nissan, Hyundai, Kia, Mazda, Lexus, Acura, Infiniti, BMW, Audi, Volkswagen, Volvo, MINI). We use manufacturer-specific diagnostic tools so each car gets dealer-level diagnosis.
How long will my repair take?
Most routine services (oil changes, brake pads, alignments) are done the same day. Larger jobs such as timing belts, transmission service, or major engine work usually take 1 to 3 business days. You get a clear timeline with your estimate.
What happens if my check engine light is on?
We scan the car, confirm the fault with live data rather than just reading the code, and tell you what it will take to fix. An illuminated check engine light is an automatic emissions failure at inspection, so do not have the code cleared the night before. The car needs a normal week of driving after a repair before its readiness monitors will pass.
Do you work on electric and hybrid vehicles?
We service hybrids from Toyota, Honda, Ford, and others, and we handle the parts of an EV that wear like any other car: tires, alignment, brakes, suspension, 12-volt battery, wipers, and cabin filters. High-voltage battery and drive-unit work on EVs goes to the manufacturer.
