Building envelope repairs are needed when there is damage or deterioration to the layer of a building that compromises its ability to protect the interior from the elements. This can include issues such as cracked or missing siding, damaged roofing materials, leaking windows, deteriorating sealants, masonry or concrete delamination, or more. These repairs are important to address promptly to prevent water infiltration, air leaks, heat loss, etc., which can lead to costly damage to the building’s structure and systems.
Before proceeding with any repairs, it’s important to understand the codes and regulations involved, how to find qualified contractors, if they offer warranties, and if they are dedicated to following good building practices.
The building envelope is the physical barrier that separates the interior of a building from the external environment. It’s composed of a combination of materials; walls, windows, doors, roofs and floors that work together to protect the building from external elements like wind, rain, sun and temperature changes. The building envelope plays a crucial role in providing thermal comfort, preventing air and water infiltration, and controlling energy consumption. It also helps maintain the structural integrity of the building and protects it from damage.
In the City of Toronto, for example, building envelopes are subject to various rules and regulations to ensure their safety, functionality, and aesthetics. The Ontario Building Code (OBC) sets out minimum standards for the design and construction of buildings, including requirements for insulation, moisture control, and air tightness. Builders and developers must comply with the OBC when constructing or renovating a building in the city.
As stated on the Government of Ontario website, “Municipalities are responsible for the enforcement of the Act and the Building Code within their jurisdiction.” Again, for example, the City of Toronto has its own set of zoning by-laws and building regulations that govern the design and appearance of buildings in the city. These regulations may include restrictions on height, setback requirements, and design guidelines for building facades. Before starting a construction project in Toronto, builders must obtain the necessary permits and approvals from the city’s building department to ensure compliance with these regulations.
Conservation districts or heritage buildings may have additional rules and regulations regarding building envelopes to preserve the historical character of certain buildings and neighbourhoods. Builders and developers working on properties in these areas must adhere to specific design guidelines and restrictions to protect the cultural heritage of the city.
It’s crucial to consult with experienced building science consultants, engineers and contractors who can help guide the rehabilitation process and ensure the desired results are achieved. Here are several factors to consider when it comes to choosing the right contractors for you:
Start by researching contractors who specialize in building envelope restoration. Look for well-established companies with an excellent reputation in the industry and interview them to get a sense of their experience, expertise and communication style.
Verify that the contractors have the necessary licenses and credentials to work on building envelopes in your area. This includes certifications in relevant areas like waterproofing, insulation and energy efficiency.
Request references and check them thoroughly. Don’t be afraid to reach out to past clients about their experiences working with the contractor, the quality of their work, their education regarding rules and regulations, and whether they respected the budget and timeline.
Before signing any contracts, review them carefully to ensure all the details are clearly outlined, including the scope of work, timelines, payment schedules, and warranties. Make sure you are comfortable with all terms and conditions before moving forward.
Regularly check in with the contractor to ensure the project is moving along as planned and that any issues are addressed promptly. Inspect the work to make sure it meets your standards, specifications and regulations.
As the project nears completion, do a final walkthrough with the contractor to address any remaining issues or touch-ups. Make sure they provide any required documentation and warranties for the work done.
Working with a Building Envelope Consultant can provide you with numerous benefits for any renovation project. They are experts who specialize in the design, construction and maintenance of building enclosures. They can ensure that building repairs and renovations meet the required standards for safety, functionality and aesthetics as they have a deep understanding of the codes and regulations involved. Working with quality contractors is just as important - they also have a deep understanding of the codes and regulations involved, obtain the necessary permits and approvals, and follow good building practices to ensure that the building envelope repairs are carried out in compliance with the applicable rules and regulations.
