Why Weekes

Diligence + Workmanship + Integrity = Trust

Principal Greg Weekes (P.Eng.) founded Weekes Engineering in 2008 to deliver professional engineering services that focused on diligence, quality workmanship and integrity. The result is a company that has built a trusted reputation in their home city of Hamilton Ontario and throughout the Greater Toronto Area.

We have learned that customers appreciate an honest assessment of their project’s viability and that is what we give—direct answers that allow project stakeholders to make informed decisions.

Thoughtful solutions

Each project is unique and we will always consider its particular needs. We then look at alternatives and their implications before making a decision on the final solution. We thoroughly understand code compliance issues related to building projects. We deliver complete solutions for building systems which are compliant with regulations and efficiency standards in effect. As a result, Weekes Engineering solutions minimize compliance risk for all stakeholders.

We have an extensive understanding and knowledge of fire stop systems and fire resistance ratings.

Weekes Engineering has professional engineering services experience and expertise in new construction, heritage retrofits, upgrades, residential, retail, commercial and regulatory compliance projects. We have an excellent reputation and the trust of architects, engineers, contractors and customers.
