“Jarrell Contracting shares NSC Applied Products Group’s passion for customer service. That is evident in their extreme attention to detail in engineering and pre-planning for a project such as St. Roch Parish School. This is matched with their talented project management, field management and service technician group that diligently works through issues that are always present in the world of commercial construction.”
“I have worked on numerous school projects: the one thing that cannot change is the first day of school. Jarrell did an amazing job of working on a tight summer schedule, while maintaining quality and excellence. “
John Berglund, St. Roch School
“The difference that a comfortable climate makes in a school setting is remarkable. Student learning is up while discipline issues are down. The teachers’ productivity is higher as is the morale of both students as well as staff. I cannot thank Jarrell Contracting enough for their outstanding work this summer in installing our AC/HVAC system. From the beginning of the project until its timely completion, we received efficient and courteous service. The people at Jarrell Contracting are truly professional tradespeople who I would recommend to anyone.”
