Separate unchanged units from altered openings

Describe exactly what will be retained and changed when confirming the project with Building staff. The linked guide does not establish a blanket exemption for every same-size replacement.

Resolve heritage review before choosing materials

Work on designated heritage properties or properties in heritage conservation districts may need a heritage permit. The City recommends discussing proposed work with staff, with the review route depending on its effect on heritage attributes. Confirm the property’s status and accepted requirements before choosing materials, profiles, divisions or finishes.

Photograph the facade as well as each frame

An elevation photo shows how openings line up and how trim relates to the surrounding wall. Add close views of sash divisions, sills and frame condition from both sides. Keep any accepted appearance requirements with the opening list. Product availability or a matching overall size does not establish approval for a protected feature.

Compare window layouts and operation

Review entrance and patio-door changes together

Include the full entry frame, sidelites, transom and threshold in the quote request. Mark swing and hardware preferences, or the operating panel for a patio door. Have your installer assess retained materials and repairs, and coordinate any changed opening with the responsible professional before final manufacturing dimensions are approved.

Compare an agreed scope of supply and installation

Use the same quantities, dimensions, glass and finishes in each proposal. Identify removal, frame repairs, sealing and interior and exterior finishing separately. For supply only, agree who approves sizes and receives the products. Check any later substitution against the accepted property requirements and update the opening schedule before release.
