Walnut Creek questions
We have no maintenance records at all. Where do we start in Walnut Creek?
With one baseline condition inspection across the fleet. It tells you what each unit needs now, and the results become the schedule going forward.
Can you work on vans parked at an office or shared lot?
Yes, as long as the property owner permits the work and there is safe space to work around the vehicle.
Do you actually come to Walnut Creek, or do I bring the vehicle to you?
We come to you. AssetStacc Mobile Service performs inspections, preventive maintenance and diagnostics at your yard, shop or job site in Walnut Creek. Work that genuinely requires a dealer or specialty vendor is coordinated by us and tracked until the unit is back in service.
Can you help with carrier 90-day inspections in Walnut Creek?
Yes. We perform contracted 90-Day Vehicle Safety Inspections for California carriers under Vehicle Code §34505.5, with separate records for trucks, tractors and trailers. The carrier's representative attests to the inspection and repairs. This is not the CHP-conducted BIT terminal inspection; annual periodic inspection booking is not offered.
Do you offer emergency or after-hours service?
Not at this time. Service hours are Monday through Friday, 7:00 AM to 6:00 PM. Extended availability is planned for the near future.
What happens to the inspection and repair records?
Everything is recorded on the asset's permanent history in AssetStacc — what was done, what was found, what is due next — so you can produce the record when an inspector, an insurer or a buyer asks for it.
What kinds of vehicles and equipment do you service in Walnut Creek?
Passenger vehicles, light-, medium- and heavy-duty trucks, semi-tractors, trailers, construction machinery and off-road equipment.
Also serving: Sacramento, Concord, Vacaville, Fairfield, Oakland, San Jose, Vallejo, Roseville, Rocklin, Rancho Cordova, El Dorado Hills, West Sacramento
