Windows and exterior doors

Balance fit, performance, appearance, and installation details.

Measure the actual openings

Existing openings may vary. Have the installer confirm dimensions and installation conditions before ordering. Record orientation, desired operation, accessibility needs, and any local performance requirements.

Compare complete packages

The product price may not include trim, flashing, hardware, screens, disposal, finish repair, or labor. Ask for a written scope that identifies the full installed assembly.

Watch the lead time

Custom sizes and finishes may set the project schedule. Confirm availability and delivery before committing to demolition or surrounding work.

Verify after installation

Check operation, locks, visible finish, weather-sealing details, and the required inspection status. Save manuals and warranty information.

Project checklist

  • Verify field measurements before ordering.
  • Compare complete installation scope.
  • Check operation and finish at handover.
Project-specific advice matters: Confirm codes, permits, product specifications, and construction methods with your local authority and appropriately qualified professionals.
