Mobile Diesel Repair
Mobile Diesel Repair
When a diesel truck breaks down, getting it repaired on-site is often faster than arranging a tow.Â
Columbia Fleet Service provides mobile diesel repair for owner-operators, commercial fleets, transportation companies, and contractors throughout Central Maryland and the Baltimore-Washington metro area.
Our 15 mobile service trucks are equipped to diagnose and repair many common mechanical problems wherever your truck is located. When roadside repairs aren’t possible, we can also coordinate heavy-duty towing and repairs through our Jessup facility, giving you one company from breakdown to repair.
