Since 2008 Marquart Equipment Repair & Sales, (a division of T.J. Marquart & Sons, Inc.) has been a trusted resource for truck and trailer repair, maintenance and fabrication. We use only OEM and high quality after market parts that we have tested on our own fleet. We do not put parts on your equipment that we would not run on our own. Down time means lost revenue and production, so we provide the best possible service, quickly and reliably. We treat your trucks, trailers, construction, agricultural, and snow removal equipment as if they were our own. Commitment to customer needs has served us well, and we look forward to assisting with your parts and maintenance for years to come.
From routine maintenance to complex engine rebuilds, we have the expertise and equipment to handle all your commercial vehicle repair needs.

“First time visiting. Definitely pleasant people to deal with. Came for a reefer wash out. Ouchy on the cost. That's the only thing they lost points for. Awesome job on the wash out 💪”
