Assess: Window Replacement

  • Insert Windows

    When replacing with an insert windows, the old sash, side jambs and trim are removed, but the original frame is left in place. The new window is inserted into this opening. This is a good option when:

    • The old sill and frame are in good condition.
    • The insert can be installed into the existing construction in a way that is square and structurally sound.
    • Casing and trim need to remain in place.

    Since the insert window sits inside the original window frame, the overall glass area may be reduced compared to the original window. The benefit of insert windows is that the interior and exterior finish materials (ie: wallpaper, paint, siding) are not compromised. Slightly out-of-square conditions of the existing frame should be accomodated, if possible. Significant out-of-square conditions should be fixed with complete window replacement.

  • Full Window Replacement

    When doing a full window replacement, the existing frame is completely removed and the new window placed into the rough opening that was occupied by the old window. This is a good option when:

    • The old window frame is deteriorated.
    • A larger opening is required by choice or by code.
    • You want to maximize energy efficiency.
    • The existing frame will not allow for an insert window.

    When doing a full window replacement, there is the opportunity to fix issues such as water or air leakage that may have occurred around the old frame.
