The two most common types of wooden windows are casement windows and double hung windows, Casement windows consist of one or more sections of sash that open out or in, depending on the design preference or a code requirement. Double hung windows have upper and lower sash sections that raise and lower as preferred they also caled as a sash windows. Replacing these windows is a relatively straight forward procedure that can be accomplished with a few basic hand tools and some knowledge of construction systems.

Once the replacement windows has been received on site, the first step is to remove the existing windows. In order to do this it is necessary to expose the window frame and clear the nails or screws that hold it in place. Where wood siding is installed it will be necessary to remove the trim pieces that surround the window. This can be accomplished with a nail bar and hammer, or other nail pulling tool.

Where the exterior walls are stucco it is necessary to remove enough stucco and lath to expose the window frame. This can be accomplished by cutting the stucco approximately 2 inches from the edge of the window frame and removing the material with a flat bar and a hammer. Be sure to clean all nails and building paper down to bare wall framing at the area of the window opening.

On the inside of the room it is necessary to remove the wall finish in order to expose the interior edges of the windows frame. Plaster or drywall can be removed in a similar manner as that used to remove the stucco. Cut the material approximately 2 inches from the edge of the windows frame and remove all nails or screws down to clean wall framing.

Next, remove any wood stops or parting bead on the windows frame and take the sections of windows sash out. For casement replacement windows it will be necessary to remove the hinges as well. With double hung replacement windows it will be necessary to remove the spring loaded return mechanism on the side of each sash.

With the edges of the window frame fully exposed, use a reciprocating saw to cut the nails or screws that attach the window to the wall framing. Run the saw blade in the seam at the top, bottom and both sides of the frame. The frame should now be ready to maneuver out of the window opening. In the event the frame will not pull out, a flat bar will most likely work to free the window frame.

Finally, install the new window frame using nails or wood screws and shim the frame to plumb and level. Install the sash panels and any stops or parting bead. Where windows are pre-assembled as a unit, the installation will not require any additional stops or moldings. To complete the installation, fill and patch the stucco and drywall and replace the exterior trim where removed.

There are many types and styles of wooden windows from which to choose. The following compares the types and styles of several wooden windows:

Awning windows allow light and breeze in a room. They are great when you want privacy but need light and ventilation. Disadvantage is the screen is set inside so dust falls onto the floor rather than into the sash windows.

Casement windows are energy efficient and great over sinks in the kitchen. They crank open so are easier to maneuver. Disadvantages are in older homes the hinges are often unstable thus increasing the risk of burglery.

Double hung windows provide superior ventilation. The top can be opened while the bottom remains close. They are great in kid’s bedrooms, dens and family rooms. A disadvantages is their tendency to leak air. A good thing to keep in mind that only half opens while other choices open both top and bottom.

Picture windows are a good choice if you are not concerned with ventilation. They provide an unobstructed view of the outdoors. They are for looks only. A main disadvantage to the picture window is the expense of replacement in case of breakage. Another thing to consider is the large area for energy transfer reduces their efficiency.

Bay windows allow for multiple views plus both sides can be open for ventilation. A disadvantage of the bay window is they generally do not include screens thus allowing insects into the room.

Hopper windows are often used in basements. It is a casement window lying on its side. The entire pane tilts inward allowing for optimum ventilation. A disadvantage of the hopper windows is since they are often placed in basements there is an added security risk for any windows on the ground level.
