This is home base. We are based in Marshville and serve the entire county - from Monroe and Waxhaw to Weddington and everywhere in between.
Home Turf - Serving Union County Since 2022
Union County is where we live and work. 704 Diesel & Welding Services is based in Marshville and we run jobs throughout the county every week - construction sites, agricultural operations, fleet yards, and everything in between.
When you call a shop that is based in your county, response times are faster, pricing tends to be more straightforward, and you are dealing with someone who has a real stake in the local community. That is what you get with us.
From Monroe down to Waxhaw and out to Indian Trail, Stallings, and Marvin - if you are in Union County and need diesel work or welding done, we are the closest call you can make.

Learn MoreWhy Local Matters
There is a real difference between calling a local operator and calling a distant company with a tech in the area. Here is what makes us different.
704 Diesel is based in Marshville. We are not a regional company with a contractor in the area - we live here, work here, and our reputation is built here. That matters when you need work done right.
When your equipment goes down in Union County, no one can get to you faster. We are already here. That kind of response time is hard to beat and can save you serious money in downtime.
Union County has a strong mix of construction, agriculture, and growing industrial operations. We work with all of it and understand what the equipment here goes through day to day.
The majority of our business in Union County comes from referrals. When a contractor calls their buddy for a recommendation, we want our name to come up. That only happens when the work is done right.
