Our Projects




We decided to contract Preston Construction for our major dental lab and childcare renovation. At Niagara College, we need to replace countertop for Lab and center. The additional design was a high quality, beautiful and our staff is happy. Preston always follows my concerns and Kevin, the project manager, offered exceptional personalized support and supervision.

Preston positively beat our expectations with their work on Our Voyageur Lab renovation. This project takes place at Niagara College Canada. They accept “Commitment as ACT not as WORDS”. We do not need to consistently monitor their work. The site supervisor – Kevin, was outstanding, and I happy to hire them again.

With positive experience, I would like to work again with Preston construction. Our Law office in City of Kitchener need Demolition, Electrical, Mechanical, Flooring work. This Project act as a base for our relationship. Without any second thought, I recommend your organization for all kind of Commercial Projects.
