Restoration Experts

As one of Canada’s largest Building Sciences team, we can quickly assemble the appropriate group of experts with the relevant experience to analyze, recommend, and above all, communicate repair and renewal solutions that balance the potential benefits with the cost and estimated life cycle. Whether correcting problems with leakage or deterioration, we combine our experience with building science theory and knowledge of the practical realities of cladding performance to create appropriate solutions for each specific project.

Heritage Preservation and Renewal

We contribute to the advancement of heritage preservation and restoration by serving on the Board of Directors and committees of industry organizations such as the Canadian Association of Heritage Professionals (CAHP) and the Association for Preservation Technology. We are retained by clients to assess the condition of heritage structures and provide recommendations on appropriate repairs. Clients also retain us to manage and review ongoing construction to confirm that the specified repairs are implemented in a manner that is not only technically correct but that minimizes the risk of disturbing the asset. On many projects, WSP collaborates with heritage architects who design programs to preserve original finishes and other heritage features.

Ours is a practical management approach. We balance the need for improved performance with many other factors, including cost, durability and physical appearance. We start heritage conservation projects by understanding the client’s objectives for the property in the short, medium and long term. We review documentation that explains the construction and significance of the building. Visiting the site allows us to explore and document the building’s current condition, performance and state of deterioration. Our repair, restoration and renewal strategies are designed to address deficiencies while being as minimally invasive as possible so as to not significantly alter the building’s form and fabric.
