Customer reviews reference specific team members including Corey, Jeff, and Larissa the Fleet Manager, with several reviewers highlighting positive delivery experiences and professional conduct. One reviewer described a load unloading process completed efficiently, while another noted staff assistance with rolling tarps during an early morning delivery. However, critical feedback exists: one customer documented repeated warranty work rescheduling without notification and unreturned phone calls regarding control department issues, and a separate reviewer reported a concerning driver interaction involving a company vehicle in traffic. These accounts present a mixed service experience for prospective clients to consider.
What Customers Say
Across 8 reviews, 5 awarded 5 stars highlighting staff helpfulness, fast unloading, and professional conduct. One 3-star review cited warranty rescheduling issues and unreturned calls, while a 1-star review complained about driver behavior. The mixed feedback suggests quality varies by department and individual technician.
