The Guy Behind 704 Diesel

Based in Marshville, NC - bringing real diesel and welding know-how directly to your job site or shop floor.

Matt Harris working on diesel equipment
Founded 2022

Built on Referrals, Backed by Real Work

Matt Harris started 704 Diesel & Welding Services in 2022 with a pretty simple idea - if the machine won't come to the shop, bring the shop to the machine. He's a hands-on guy who'd rather drive to your job site and get things fixed than have you sit around waiting for a tow.

Word got around fast. Most of Matt's work still comes through referrals and word of mouth, which is a good sign that people are happy when he leaves. He's built a reputation across Union County, Mecklenburg County, and into South Carolina for showing up, keeping it straight, and getting the job done right the first time.

One thing Matt noticed early on: clients would sometimes not realize all the things he could actually do. He'd wrap up one job and then get called back weeks later for something he could've knocked out the same day. That's exactly why this site exists - so you know everything on the table before you call.

More Than Just a Wrench

A lot of diesel mechanics stick to one thing. Matt doesn't. Between mobile service calls and shop work, he covers a wide range of diesel and welding work that most people don't realize they can get from one guy.

Diesel Mechanic Work

Engine diagnostics, repairs, and maintenance for diesel trucks and heavy equipment - out in the field or at the shop.

Learn More

Mobile Welding

On-site welding wherever the job takes him - structural repairs, broken frames, busted implements - handled right where the problem is.

Learn More

Heavy Equipment Repair

Excavators, loaders, skid steers, dozers - if it's big, diesel-powered, and broken, Matt knows how to get it moving again.

Learn More

Line Boring

Save money on parts by having worn bores machined back to spec on-site. Cheaper than buying new and faster than shipping it out.

Learn More

Industrial Welding

Shop-based industrial welding repair for tougher structural and fabrication jobs that need the right setup to do correctly.

Learn More

Metal Fabrication

Custom fabrication work from the shop - brackets, frames, guards, repairs, or anything that needs to be built from scratch or rebuilt stronger.

What Makes 704 Different

There's no shortage of mechanics and welders out there, but finding one who will actually come to you, knows heavy equipment inside and out, and can handle both the mechanical and the metal work on the same visit - that's a shorter list.

We Come to You

No tow truck fees, no waiting around. Matt brings the tools and the know-how directly to your job site, farm, or yard.

One Guy, Many Skills

Diesel mechanic, welder, fabricator, line boring - Matt handles it all. You get one contact for the whole job instead of juggling multiple contractors.

Straight Talk

You'll get a real answer on what's wrong and what it'll cost. No upselling, no confusion - just honest work at a fair price.

Fast Turnaround

Downtime costs money. Matt understands that and works to get you back up and running without dragging things out.
