Incorporated in 1992, Serianni Construction is built on a solid foundation that dates back to 1958, when our father, Basil Serianni, a Master Cabinetmaker, came to Canada and embarked on a lifetime of quality craftsmanship that continues to this day.

What began in the early ‘60s as sole proprietorship based mainly on custom residential work has grown into a full-fledged, family-run corporation that provides general contracting, pre-construction, construction management and design/build for major corporate, industrial, commercial, institutional, municipal, residential and multi-residential clients in Niagara and beyond.

Our business has been family owned and operated for more than 50 years. We offer a full range of construction services and we have the human, material and equipment resources to take on jobs of any size. We are flexible in our approach and recognize that each project is unique. Through many years of experience, we have developed the skills, techniques and expertise to ensure a successful project completion every time. Founder Basil Serianni still runs our millwork shop, and his words guide our approach to every job we do: “Do it right, do it once, and do it like it’s yours.”

Our philosophy is simple: provide premium-quality construction at competitive rates, while maintaining absolute personal commitment and involvement with our clients, and with the design and consulting professions. It’s a way of doing business that has served us well, and resulted in a strong reputation for quality, effectiveness and efficiency. Our long list of satisfied customers continues to grow, and now reaches far beyond our local base, and throughout Ontario.

We take pride in our growing number of repeat clients, including Tim Hortons (TDL Group Corp), Niagara College, the City of Welland, the City of Port Colborne, the Niagara District School Board, Welland Forge, MMFX, and many others. Our clients tell us they value our attention to detail, professionalism, competence, and, most importantly, consistently completing projects on time and on budget.
