New Construction Installation

Lots of customers would rather have their windows and doors installed with new construction installation rather than retrofit because new construction installation makes your new windows or doors look like they were built with your home with minimal to no glass loss. This type of installation requires specially skilled installers but more importantly an artisan stucco team which we have here at XO Window Systems.

RETROFIT INSTALLATION Services

This type of installation is more cost affective than new construction installation and requires no disturbing of your exterior stucco or wood siding. The original window frames are left in the walls to maintain the homes original weather/vapor barrier. The new windows and doors are installed over the old original frames using a mounting flange or z bar framed window or door. In most cases there is no painting required for retrofit windows and most work is done within 1 or 2 days. A window is only as good as it’s installation!
