Excellence
Built from the Ground Up
Founded in 2017 by Tristan McKay in Cornwall, Ontario, SD&G Contracting began with a simple promise: do the work right, treat every client like a neighbour, and build something that lasts.
What started as a small local operation has grown into a thriving team of dedicated professionals serving residential and commercial properties across Cornwall and the surrounding SD&G region. From our humble beginnings, we've built our reputation on three pillars — Expertise, Commitment, and Innovation.
Over the years, we've cultivated a passionate and skilled crew that shares one common goal: delivering exceptional quality for every client, on every project. We continue to grow and evolve, always ensuring our work reflects the values and dedication that have defined SD&G since day one.
