Weather Stripping
Wood window sashes give the classic look to your home and, when properly maintained, they will last for a long time. However, they can be damaged or degraded over time due to exposure or normal wear and tear. Fortunately, sash repair specialists can restore your windows to their original condition and maintain their appearance for longer than replacement windows.
The first step in sash window repairs is addressing weather stripping, which is found on both the sash and frame. It can cause drafts if it's worn or loose. To fix it, start by determining the brand of your window and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its height and width so that you can locate replacement weather stripping to match.
Then, take the sash from its holder and place it on flat surfaces to allow you to reach all four sides. If the sash is double glazed window repairs-hung, remove the ropes and weights that should have fallen into the pocket inside the jamb lining. After removing the sash using the utility knife, you can remove the weather stripping that was left by hand or using a putty knife.
After the sash is cleared, you can install the stoppers that separate the two sashes. These are long pieces of wood that are used to separate the two sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimming from the lumberyard. However, you could also substitute with a scrap piece of wood.
After removing the parting stops and cutting them to the desired length and thickness, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife, and then let it dry for at least a few days. When it's completely dried then apply a top coat of acrylic latex paint. This will help protect the putty, and give your sash a modern look.
Sash Hardware
The hardware that supports the window sashes can wear out over time and with use. This can result in the window or door that is difficult to open or close. It's a good idea to know that replacing and repairing this hardware is often simple and inexpensive. If a sash is difficult to operate, try spraying some lubrication into the jamb channel then open it to see if this solves the issue. If not, the issue is most likely due to the sash balance and you'll have to take off the sash to access this hardware.
Window sashes need to open and close with little effort. However, this may be difficult if the weights are worn out or the sash-to-rail connecting rail isn't properly coated. This issue can be caused by a variety of factors, including insufficient maintenance or a mismatched weight rating for a particular sash.
If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash's to drag and eventually hit the frame in the corner that's directly opposite the hinge arm (Photo 1). To address this issue, first make sure the sash is firmly seated in the frame's opening and then remove it from the window. If the sash is attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, old windows, especially those in older houses, could be difficult to open and close. In most instances, a few easy repairs can turn these windows into smooth operators for the first time and save the homeowner money on energy costs.
In order to make these sash repairs it is important to have all the necessary tools in place before you begin. Mark the hinge channel's location on the frame (Photo 1) using pencil. This will make it easier to put the channel in the right position after you've finished. Remove the sash, and then remove the hardware including the parting beads (Photo 2) and the cords or chains that hold it in place. Heat gun with nozzle shield and a medium setting will soften any hardened putty. Remove the old sash and keep it in a labeled bag.
Sash Weights
If your window sash repairs are to replace a broken cord or to ensure that the windows are functional by replacing worn out sash weights will improve sash operation and cut down on energy costs. Sash weights consist of heavy iron or lead cylindricals that are contained in a hidden cavity and Window repairs are connected via a rope to the movable window sash. They are counterbalancers which allows the window to be opened and closed without the need for mechanical or electrical devices. If they fail, sashweights are usually neglected or not used by homeowners.
It's not easy to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits properly. You will also require an additional piece of string, a length sash cord, and a few sash pulleys that will tie the new sash weights the sash cord.
Older windows made of wood are joined by mortise and tenon joints. Hammers and pins can be used to take out the wood pegs holding the parts together. The majority of them have large diameters on one side and a smaller one on the other, which is why it is crucial to take out the small-diameter sides first. Later sashes made use of glue instead of pins. They can be cut with a knife and a mallet.
Once the sash has been removed, you can take off the sash stops and gain access to the weight pockets. This is usually done via a small hole at the bottom of every jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings.
After 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. Be sure to weigh the sash prior to you do this, as the weights that were previously used may be different in size from what is needed. After the new weight is 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 adjustment.
Sash Cords
Most old double-hung windows come with a chain or cord attached to the weights that helps keep the sashes balanced within the jamb. Over time, these cords can get damaged and make it impossible to raise the windows. A new sash cord will give you the ability to move the sash upwards and downwards and hold it in place when opened.
The first step to replace sash cords is to locate and remove the access panels within the jambs. They are typically attached by nails or screws and must be removed. It may be possible to take them out using the hammer or chisel however, it is best to lay out dust sheets before starting any work.
Once the access panel is removed, you can start working on the sash. Take the narrow beads (also called "tie rails") out of their grooves with a chisel or flat bar. It is important to be patient, as these are often stuck or nailed to the floor. If the sash remains in place, break the mortise and tenon joints with the help of a hammer and pin or screwdriver, then remove the wood pegs attached to each piece. The sash should be able move freely, however it might require some lubrication in order to feel less stiff.
With the sash open Take a measurement of the sash chain to extend from the pulley at the top of the jamb to the sash slot in the bottom. Cut the cord/chain and then secure it as in Step 6 above. You can either employ a hammer and nail or screws, but nails are less likely to cause damage.
It is best to keep the original weights in place unless you've purchased a kit that will replace the counterbalance. They're not costly and easy to install if you buy them from architectural salvage stores.
