Window Sash Repairs
Make sure to check the sashes of your windows regularly for damage, mildew, and mold. If you catch these issues early you can save money on repairs in the future.
The sash is an interior frame that moves upwards and downwards in windows that open. This article will teach you how to make several easy repairs to your sash.
Weather Stripping
Wooden window sashes can add an elegant appearance to your home. They are also sturdy and can last many years provided they are properly maintained. They can, however, be damaged or degraded over time due to exposure and normal wear. Fortunately, sash repair specialists can bring your windows back to their original condition and keep them looking great for much longer than newer replacement windows.
Weather stripping is the first aspect to consider when you are repairing windows with sash. It is located on both the frame and sash. It can cause drafts if it's damaged or is loose. Start by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corner or on the aluminum spacers between panes). Then, take the sash off and mark its width and height, so you can find the appropriate weather stripping replacement to match.
Then, remove the sash from the holder and place it on a flat surface to allow you to access all four sides. If your sash has a double-hung, you'll need to remove the weights and the ropes that go with them which should have slipped into the pocket that was intended to be in the jamb liner. After removing the sash using the utility knife, take off the old weather stripping by hand or using a putty knife.
After the sash has been cleared, you can replace the parting stops. These are long pieces that split the sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you could also substitute a scrap piece of wood.
After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife, then let it dry for at least a day. Once it's fully cured, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a new look.
Sash Hardware
The hardware that supports window sashes can wear out over time and use. This could result in a door or a window that is difficult to open or close. It's important to know that replacing or fixing this hardware is usually straightforward and cost-effective. If you are having trouble opening a sash, spray some lubricant into the jamb channel. Then slide the sash out to see if it resolves the problem. If the issue continues it's likely the sash balance. You will need to remove the window sash to access the hardware.
Ideally, window sashes must swing open and closed with minimal effort but this is a difficult task when the weights are worn or if the sash that joins rail isn't properly glazed. This problem can be caused by a number of reasons, such as lack of maintenance or by a mismatched weight rating for the particular window sash.
If the hinge arms on windows begin to slide, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To correct the issue make sure the sash is centered in the frame's opening and remove it. If the sash has been screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).
Windows that are old, especially in older houses, can be difficult to open and close, due to hinges that are sagging and general lack of energy efficiency. In many instances, a few minor repairs can transform these windows into smooth operators again and save the homeowner money on energy costs.
It is crucial to have the tools you need before you start. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will allow you to get the channel back into the correct position after you've finished. Remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place. The nozzle shield of the heat gun and a medium setting will soften any hardened putty. Take off the old sash and put it in a labeled bag.
Sash Weights
If your window sash repairs are to replace a damaged cord or to keep your windows functioning, replacing worn out sash weights will improve sash operation and help reduce energy costs. Sash weights are composed of iron or lead cylindricals that are contained in a concealed cavity and connected by ropes to the moveable window sash. These weights act as counterbalances, which allows you to open and close the window without the need for mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they break; therefore, you may need to search for replacements.
A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to find a replacement that fits properly. You will also need a new piece of string, a length of sash cord, and a few sash pulleys to connect the new sash weights the sash cord.
Mortise and Tenon joints can be used to join older wood windows. The wood pegs that hold the components together can be removed using a pin punch and hammer. The majority of them are large on one side and smaller on the other. It is essential to first remove the smaller diameter sides. Later sashes utilized glue instead of pins. They can be cut by using a knife and mallets.
Once the sash has been released, you can remove sash stops and gain access to the pockets for weights. This is usually done through tiny holes at the bottom of every jamb. Full Document is then covered by an access panel made of wood which can be removed to allow you to view the inside of the frame.
Once the sash is stopped and the access panel is removed, you are able to remove the weight you used and replace it. Make sure you weigh the sash prior to you do this, since the old weights may be different sizes than what is needed. After the new weight has been installed, thread the string through the sash pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches at the head of the string for future adjustments.
Sash Cords
Most double-hung windows of the past come with a chain or cord attached to the weights which supports and keeps the sashes balanced in the jamb. As time passes, these cords may become damaged and make it difficult to raise windows. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its position when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. These are usually screwed or nailed into and need to be removed. You may be able to use a hammer and chisel for removing them, but it's always better to lay down dust sheets prior to beginning any work.
After you have removed the access panel, you can begin working on the sash. Take the narrow beads (also called "tie rails") out of their grooves with the chisel or flat bar. They are typically wedged into or nailed but can be removed and it's worth your time here. If the sash is still in place, pry the mortise-and-tenon joints out with a screwdriver or hammer and then take out each wood peg. The sash should be able to move freely now, but it may require some lubrication to make it feel less stiff.
With the sash open With the sash in an open position, measure the sash chain or cord to extend from the pulley on the top of the jamb to the sash slot at the bottom. Cut the cord or chain and secure it as in the previous step. You can use a hammer and screws or nails, but nails are less likely to cause damage.
It is recommended to keep the original weights in place unless you have purchased a kit that will replace the counterbalance. They are not expensive and are easy to install if you buy them from architectural salvage stores. Depending on the size of your window one or two sashweights could be needed to keep it open.
