Sometimes it is necessary to replace casement windows depending on design and functional considerations. There are valuable energy efficient and ventilating window styles that can be added to fit particular applications. However, if the window is not consistent with the architectural design or it does not suit or complement a particular opening, then it can be removed and replaced with double hung windows.
Removing Hinges on Casement Window
Casement windows are supported by loose pin hinges or fixed pin hinges. For a loose pin hinge, use a flat blade screwdriver to loosen the screws or position a tack puller beneath the top ball of the pin and gently hammer it outwards. This easily removes the hinge.
The correct method of removing a fixed pin hinge is to undo screws that hold the leaf of the hinge to the sash or the frame. Loosen the screws using a screwdriver and remove them from the hinge.
There are casement windows that are reinforced into position using molding. In this case, use a putty knife and place it in the gap between the molding and the extension jam. Use a wood mallet or hammer to gently tap on the putty knife; work on all four sides of the casement window to loosen the molding.
Release Casement Window
To remove the window from position, place a crowbar between the loosened molding and the extension jam. Push it a little in and take care not to use too much force, then pry the molding off and work on all the four sides of the window.
If there are nails, use a claw hammer to pull them out and remove the jamb located inside of the window. On the outside, find if there are shingles and nails and remove them as well.
Carefully pull out the casement window from the opening and place it in a safe position.
Preparation to Install Double Hung Window
Use a stiff brush to remove old caulk and paint debris from the window opening. A chisel can be used to chip out hardened and stubborn caulk. Brush out the entire surface and pay attention to the jamb, sill and the surrounding wall.
Look out for cracks, seals, or gaps on the surface and make necessary repairs.
Repair Jambs and Sills
If the surface around the window’s opening are uneven or have imperfections, use coarse sandpaper to smooth the surface. Remove the debris or particles using a soft brush and prepare caulk to even out the surface.
Apply an even coat of caulk on the wall, jamb or sill and let it dry completely before putting a second layer.
Wear protective working gloves and overalls when removing casement windows. Pay attention when working with the hammer and old nails to prevent injuries or accidents.
Always use a well built ladder when working on windows positioned high up on the wall. Make sure it is firmly propped and secured against the wall.
