Services We Offer
Plumbing
P.J. Dionne Company began as a plumbing company and plumbing still comprises the majority of our work. Our projects range from simple service calls to complex new construction or renovation projects valued at several million dollars.
HVAC
Commercial heating, ventilation and air conditioning is an expanding component of our business, guided by our highly experienced HVAC Project Manager. We install and maintain a wide range of HVAC equipment from leading manufacturers.
Service & Maintenance
Our plumbing and HVAC service professionals are problem solvers. We seek not only to address the immediate issue, but to identify conditions that limit system performance and offer cost-effective solutions. We strive to fully inform customers about the causes of any problems so that they can make educated choices regarding repair or replacement.
BIM / Pre-Fab
As mechanical systems become more specialized and complex, it becomes more difficult to fit them, with adequate clearances, into the finite space of walls, ceilings and utility rooms. We’re expanding our use of Building Information Modeling (BIM) to determine the optimal design and prevent conflicts before they happen.
