Weather Stripping

Wood window sashes give the classic look to your home. If properly maintained, can last for years. However, they can be damaged or degraded over time due to exposure and normal wear and tear.

Start by identifying the window's brand and the manufacturer's date (etched on the corner of the glass or on the aluminum spacers between panes). Remove the sash and mark its width and height so you can get new weather stripping that is compatible with the original.

Then, remove the sash from the holder and place it on flat surfaces to allow you to access all four sides. If your sash has been double-hung, take out the weights with their ropes that should have fallen into the pocket inside the jamb lining. After removing the sash using the utility knife, remove the old weather stripping by hand or using a putty knife.

Once the sash is clear it is time to replace the parting stops. These are long pieces wood that divide the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimming from the lumberyard. But, you can substitute a scrap piece of wood.

After removing the parting stops and trimming them to your desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using your putty knife, and let it dry at least a day. Once it's fully cured then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new appearance.

Sash Hardware

The hardware that supports window sashes susceptible to wear and tear due to time and usage, and the result can be a door or window that can't be opened or closed easily. It's a good idea to know that replacing or fixing this hardware is usually simple and inexpensive. If you are having trouble opening the sash, spray some oil into the jamb channel. Then, slide the sash out to see if that fixes the issue. If the problem persists it's likely that the sash balance is off. It is necessary to remove the window sash to access the hardware.

The ideal situation is for window sashes to swing open and closed without effort, however, this can be an issue when the weights are worn or if the sash that joins rail isn't properly glazed. This issue could be caused by a number of factors, including the lack of maintenance or the wrong weight rating for the specific sash.

If the hinge arms on the window begin to move, this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To fix the problem, make sure that the sash is aligned in the frame opening, and then remove it. If the sash has been attached to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Due to hinges that are sagging, and a general lack in energy efficiency, windows that are old, especially those in older houses, could be difficult to open or close. In most cases, a few simple repairs can transform these windows into smooth operators and save homeowners cash on energy costs.

It is important to have the tools you need before you start. Mark the hinge channel location on the frame (Photo 1) using pencil. This will allow you to position the channel in the proper location after you've completed.

Sash Weights

Sash weights can be replaced to improve the operation of your window sash, and also reduce the cost of energy. Sash weights consist of iron or lead cylinders that are encased inside a concealed cavity, and are connected via a rope to the movable window sash. These weights provide counterbalance, allowing the window doctor (continue reading this) to be closed and opened without the need for mechanical or electrical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.

A sash weight that has fallen out of the cavity is difficult to get back and you'll need to find a replacement that is suitable for the. You will also require a new piece of string, a length sash cord, and a few sash pulleys to connect the new sash weights onto the sash cord.

Older windows made of wood are joined with mortise and tenon joints. The wood pegs holding the components together can be removed by pin punches and hammers. The majority of these pegs are large on one side and smaller on the other. It is important to remove first the smaller diameter sides. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallets.

Once the sash is freed, you can remove the sash stop and access the weight pocket. Usually it is done by drilling an opening in the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the inner workings.

Once you have the sash stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with the new. Make sure you weigh the sash prior to you do this, as the weights that were previously used may be different sizes than what is needed. After the new weight has been installed, thread a string through the sash pulling mechanism. Then nail the string to the boxed frame, leaving a few inches of string protruding from the head for future adjustments.

Sash Cords

In the majority of double-hung windows the chain or cord is affixed to the weights. This keeps the sashes of the jamb level. As time passes, these cords can become damaged and make it impossible to raise the windows. A new sash cable will restore the ability to move and lower the sash, and ensure it stays in place when opened.

The first step to replace sash cords is to locate and remove the access panels within the jambs. These are usually fixed or screwed in and must be removed or moved. You could use a hammer or chisel to remove them but it's best to lay down dust sheets before beginning any work.

After you have removed the access panel, you are able to begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using a chisel or flat bar. It's important to be patient because they are usually placed in a wedge or nail. If the sash is still in place, pry the mortise and tenon joints free with a hammer or screwdriver, then remove each wood peg. The sash should be able move freely, however it may need some lubrication to feel less stiff.

Determine the length of sash cord/chain needed to reach the sash slot at the bottom of the pulley on the top of the jamb. Cut the chain or cord and secure it in the step 6 above. You can use nail, hammer or screws. However, nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the counterbalance system that was in place before, it's best to keep the original weights for balancing in place. They are not expensive and simple to install if purchased them from architectural salvage stores.
