Replacement vs New Construction Windows

Window replacement is just how it sounds. We pop out the old sashes and replace them with a pocket replacement window built to fit within your existing window frame. Windows are most commonly replaced to improve energy efficiency like upgrading from old single-pane to double-pane glass, for example.

New construction windows requires the removal of the exterior and interior trim around the window in order to expose the studs of the home. It is a more involved process for your contractor to ensure the exact match of exterior materials. New construction is a good option if you think the studs and frame of the window should be replaced because of damage, or if you are planning on replacing the exterior of your home such as new siding or exterior window trim.

Replacement Windows (sometimes referred to as ‘retrofit’)

  • Installation is fairly quick
  • Less expensive – labor and required materials are not as much
  • Still can upgrade the quality and energy efficiency

New Construction Windows

  • Allows for different sized windows
  • Allows for different window placements (like the image below)
  • Allows for improved insulation where needed

 New construction windows allows for more light in the living room
