Replacement windows fit inside the existing window frame, so you only have to change out a few pieces to install new windows.

If your window frame is soft from water damage, you may need to replace the frame. To find what size window you will need, measure the width at the top, middle and bottom. Also measure the height at the left, right and middle.
For older windows, use a putty knife and pry bar to carefully remove the stops holding the window in the frame. Cut the balance cords for the bottom sash with a utility knife and allow the weights to fall. Lift out the bottom sash. Remove the parting stops. Lower the top sash and cut the balance cords. Remove the top sash. Then remove the balance cord pulleys.
Raise the bottom sash. Remove the screws along the sides of the plastic stops and remove the stop. Lower the sash, cut the cords and remove it. Remove the top sash the same way and remove the remaining stops.

If you have a stucco house with aluminum frame, start by measuring the width at the top, middle and bottom. Also measure the height at the left, right and middle.
Tape an “X” pattern on the windows in case the window breaks. To remove the sash, open the window, lift it out and tilt the bottom out. Unscrew and remove the divider. Remove any screws along the fixed glass’s frame. Slid the sash toward the middle, lift up and tilt the bottom out to remove it.
