Exterior Renovations
Window performance depends on the product, opening, installation, and surrounding wall working together. Accurate planning records dimensions, operating style, interior and exterior finishes, access, water-management details, and any signs of damage so the scope covers more than setting a new frame in place.
Some projects replace units in existing openings, while others alter opening size or configuration. The City identifies different permit considerations for those scopes, so the proposed change and current requirements should be checked before ordering. Structural, bedroom-egress, and exterior-finish implications can also affect the plan.
Room-by-room window planning
Each opening is reviewed for light, ventilation, privacy, furniture placement, safe operation, cleaning access, and the needs of the room. Bedrooms and altered openings deserve additional attention. A schedule records sizes, configurations, colours, hardware, glazing choices, trim, and required repairs to reduce ordering and installation ambiguity.
Existing openings versus structural changes
The City notes that replacing a window with the same size and type can follow a different permit path than creating or enlarging an opening. Structural changes and other project conditions may require approvals. Final requirements should be confirmed for the address and full scope before fabrication begins.
Connecting the window to the wall
Installation planning addresses sill support, flashing, drainage, air sealing, insulation, exterior cladding, and interior finish transitions. The correct detail depends on the wall and product system. Existing leakage or deterioration may require additional repair, which should be documented and approved instead of hidden behind new trim.
Installation, protection, and handover
The sequence considers occupied rooms, furniture protection, security, weather exposure, dust control, and safe access. Openings should not be left vulnerable longer than necessary. Closeout includes operation checks, finish review, care information, and a clear record of approved changes or concealed-condition repairs completed during installation.
