Frequently Asked Questions

Here are some of the things people ask us most. If you do not see your question here, just give us a call.

We are based in Marshville, NC and travel about 50 miles in all directions. That covers Union County, Mecklenburg County, Cabarrus County, Stanly County, Lancaster County SC, and Chesterfield County SC. We have gone further for certain customers when the job calls for it.
We come to you. Whether it is a job site, a shop yard, a farm, or a construction project - Matt loads up the truck and rolls out to wherever the equipment is sitting. Most work gets handled on the spot without any hauling.
Yes - that is the whole point of 704 Diesel and Welding Services. Most mobile mechanics stick to engines or stick to welding. We do both, plus metal fabrication, line boring, and heavy equipment repair. You deal with one person and one truck instead of hunting down two different contractors.
Line boring is a machining process that restores worn pin bores back to factory tolerances. When the bore on an excavator arm or loader pivot gets sloppy from wear, line boring can fix it in place instead of requiring you to buy a whole new component. It saves significant money on heavy equipment repairs.
We do our best to respond quickly when equipment goes down mid-job. Call (704) 291-0286 and describe the situation. We will give you an honest answer on how fast we can get out there. We know downtime costs money and we do not drag our feet.
