About Us

We are a locally owned and operated diesel repair shop proudly serving King George, VA and surrounding areas. We specialize in service and repair for medium-duty trucks, heavy-duty trucks, and all types of trailers. We have a passion for diesel trucks and helping hard working people stay on the road. Demand for diesel repair is rising — and we’re here to meet it with expertise and efficiency. 

Integrity & Precision - We believe in doing what's right. Honest diagnosis and fair pricing. Every repair is performed with accuracy, backed by experience and proper tools.

Accountability - We stand behind our work. If something is wrong, we make it right.

Transparency - We diagnose, explain what's wrong, what it'll take to fix, and what it'll cost - before we turn a wrench.

Safety - Every truck and trailer we service leaves our shop roadworthy and ready - safety cannot be compromised.

Trust - Built over time, earned everyday. We believe the strongest part of our business isn’t the tools in our shop — it’s the trust we build with our customers. We value every relationship, and it shows in the way we communicate, the honesty in our diagnostics, and the pride we take in every job. Whether it’s your first visit or your fiftieth, you’re not just another ticket — you’re part of the HDR Services family.
