Drivers for the company have shown up in multiple accounts using trucks numbered like 06, 50, and others on roads such as 281, Walzem Road through active school zones, 1604, and Interstate 35 near exit 174A, where reports mention speeding over posted limits, passing in turn lanes, phone use behind the wheel, and close calls with other drivers that put vehicles and people at risk during regular service runs.
Customers have flagged repeated problems with how the trucks are handled on San Antonio area roads, which drags down marks for communication and overall reliability even when the core trade work gets done. Speed and quality ratings suffer from these incidents that happen during normal travel between jobs, while price feedback stays mixed since the company advertises competitive rates but the driving issues overshadow any savings.
