Stud to Stud.
All parts of your existing windows will be completely removed all the way back to the studs. New windows will be installed in the centre of the wall with new jamb extensions either in wood or vinyl. The exterior of your new windows will be complimented by new aluminum flashing that will tie your new windows with the existing structure of your home. All aluminum flashing will be caulked in order to ensure that no water can penetrate the perimeter. Windows will receive minimum of two passes of insulating foam after which new interior casing will be applied to finish up the job.
