They are proactive in communicating upcoming preventative maintenance and ensure we are well informed ahead of time, which helps us plan efficiently and avoid unexpected disruptions. We have been extremely satisfied with the performance of Southeast Repair.

On 4/2/2026 Will Denival had this to say:
Wavexpress Transportation inc- My truck had a coolant leak and I called Joe. He came out and diagnosed the truck and informed me what the issues were and how to best take care of it and advise me on what I needed to do and he didn’t charge me anything but gave me some real helpful advice because the part needed to fix the truck was out of stock. Joe is an honest and straightforward mechanic which is refreshing to see in this industry.

On 2/9/2026 Luis Painting had this to say:
