Service Areas
Mobile diesel mechanic and welding services brought directly to your location anywhere in Mecklenburg County and the Charlotte metro area.
Serving Mecklenburg County Since 2022
Mecklenburg County is one of our most active service areas. The Charlotte metro has no shortage of construction activity, fleet operations, and industrial equipment that needs attention - and we are out there regularly keeping things running.
Whether you are managing a construction site in south Charlotte, running a fleet out of a warehouse in Huntersville, or dealing with a piece of equipment that broke down somewhere off I-485, we can get to you. Matt covers the whole county and is familiar with the area.
From routine diesel service and diagnostics to emergency welding repairs on heavy equipment, we handle it on-site so you are not towing anything anywhere.

Learn MoreWhy Local Matters
Working with a local mobile mechanic means faster response, less downtime, and someone who actually knows your area.
We run a tight service area out of Marshville - Mecklenburg County is well within range. That means we can typically get to you faster than a larger shop with calls backed up across a bigger territory.
We work with contractors, fleet operators, and equipment owners throughout the Charlotte metro on a regular basis. We know the kind of work that happens here and what it takes to keep equipment running.
When a piece of equipment breaks down on a job site in Charlotte, the last thing you need is a tow bill on top of repair costs. We come to you and handle it right there, keeping your costs down and your schedule intact.
Most of our business comes from word of mouth. Contractors and equipment operators in the Charlotte area keep calling back because we do the work right and stand behind it.
