Our Flawless Window Installation Process

Opening review and layout planning

For patio doors, we review the opening, floor level, and traffic pattern, then measure for the right configuration and track system.

Door configuration and ordering

You choose between sliding or French‑style units, glass and grid options, and hardware, while we handle ordering, access planning, and timing with your deck or patio.

Windows Installation Estimation

Precise installation and adjustment

We prepare the sill, set the frame plumb and square, insulate and seal around it, then adjust rollers, locks, and weatherstripping so the door glides easily and seals tightly.

High-performance windows & doors built for Quebec’s harsh winters and hot, humid summers.
