Window installation: what the scope should cover
Installation quality matters alongside the window itself. Understand the work around the opening before comparing bids.
A complete installation scope
The written scope should identify removal, opening preparation, installation method, fastening, water management, air sealing, insulation, trim, cleanup and disposal.
Water and air management
Windows are part of the wall system. Flashing and sealants help manage water, while perimeter sealing and insulation help limit uncontrolled air movement.
Interior and exterior finishing
Clarify whether casing, trim, sill work, paint or stain touch-up, exterior capping and siding repairs are included.
Final walkthrough
Operate each window, check locks and screens, review visible sealant and trim, confirm cleanup and collect warranty and product documentation.
