Patio Door Replacement as Building Envelope Restoration by Window & Door Solutions

Existing patio door systems often fail due to air leakage, moisture intrusion, flashing breakdown, and structural movement. These failures affect the continuity of the wall assembly and reduce the overall thermal and structural performance of the building envelope.

At Window & Door Solutions, patio door replacement is treated as a building envelope restoration process rather than a simple unit change. Each replacement addresses system failure at the interface between exterior cladding, structural framing, and interior environmental separation layers.

The replacement process restores proper alignment between framing, insulation, and environmental control layers. This ensures the opening functions as a fully integrated part of the wall system under Canadian environmental conditions, including wind load, precipitation exposure, and seasonal thermal variation.
