As described above, in the present invention, after cutting the outer wall of a building into a rectangular shape and removing the old window frame, a new window frame is attached from the outdoor side, and an adjustment frame is attached to the outdoor side of the mounting piece of the new window frame. Since we installed caulking material between the adjustment frame and the cut surface of the outer wall, the rectangular adjustment frame and the cut line of the outer wall surrounding it will be attached to the outside of the window after the replacement work is completed. Moreover, since the space between the adjustment frame and the cut surface of the outer wall is sealed with caulking material as described above, it is possible to reliably prevent rainwater from entering from this space for a long time. In addition, after fitting the new window frame into the opening from the outdoor side, a spacer is inserted through the notch in the mounting piece of the new window frame to position the new window frame, so little or no repair is required on the interior wall. The windows can be replaced without any problems, which shortens the construction period and reduces costs.
