Replacement Windows and Patio Doors

Replacement vs. New Construction

Replacement windows, also known as retrofit windows, are designed for existing structures and are installed within the existing frame. This simplifies the installation process, saving time and money, because the contractor typically doesn’t have to remove any exterior siding, interior trim or expensive moulding. Replacement windows are available in a variety of styles and sizes, including custom sizes, to fit almost any opening. 

If your window frames aren’t in good condition, you’re planning to create a new or enlarged opening or you’re replacing siding, you may want to consider using new construction windows instead. They’re designed with a nail fin for direct fastening to the studs. 

Considerations for replacement or retrofit patio doors are generally the same as new construction patio doors.
