Window Sash Repairs
Check the windows sashes regularly for any damage, mildew and mold. You can avoid the cost of repairs in the future by catching these issues in the early stages before they become out of control.
The sash is an inside frame that can move vertically up and down in windows that are open. This article will show you how to do a variety of simple repairs to the sash.
Weather Stripping
Wooden window sashes can add an elegant look to your home. They are also sturdy and will last for many years when they are maintained properly. However, they can become damaged or degraded with time, due to exposure and normal wear. Sash repair specialists can restore windows back to their original condition and keep them looking great much longer than replacement windows.
The first step for sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. If it's loose or worn out, it could cause drafts, as well as other issues. To fix it, start by finding your window brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its width and height so that you can locate the appropriate weather stripping replacement to match.
Then, remove the sash from its holder and place it on flat surfaces to allow you to reach all four sides. If your sash has a double-hung, you'll need to remove the weights and their ropes that should have fallen into the pocket of the jamb liner. Once you've removed the sash and the weights, use a utility knife to remove the weather stripping that was formerly in place at the corners. Then, remove it manually or using a putty knife.
Once the sash is clear, you can replace the parting stops. These are long pieces wood that divide the two sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, however you could also use scrap wood.
After removing the parting stops and cutting them to the desired length then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty tool and let it dry at least a day. After it has fully dried, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a modern appearance.
Sash Hardware
The hardware that holds window sashes is susceptible to wear and tear from time and usage, and the result can be a window or door that isn't able to open or close easily. The good news is that repairing and replacing this hardware is typically quite simple and inexpensive. If you're having trouble opening the sash, spray some oil into the jamb channel. Then, slide the sash out to see if it resolves the issue. If the issue continues, it is most likely to be due to the sash's balance. You'll need to take off the window sash to get access to this part of the hardware.
The ideal situation is for window sashes to swing open and closed without effort, but this is difficult when the weights wear out or if the sash's meeting rail isn't properly coated. This problem can be due to various reasons, including an absence of maintenance or a mismatched weight rating.
If window repairs near me on a window begin to sag this could cause the sash to drag and then hit the frame in the opposite corner (Photo 1). To correct the issue make sure the sash is centered in the frame's opening and take it off. If the sash has been fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, older windows particularly those in older houses, could be difficult to open and close. In most instances, a few minor repairs can turn these windows into smooth operation and save homeowners cash on energy costs.
It is important to have the tools you require before you start. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will allow you to put the channel in the correct location after you've completed. Then, remove the sash and take off the hardware including the parting beads (Photo 2) and the cords or chains which hold it in place. The nozzle shield of the heat gun and a medium setting will soften any putty that has been hardened. Remove the old sash, and keep it in a labeled bag.
Sash Weights
Sash weights are able to be replaced to enhance the efficiency of your window sash and reduce energy costs. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and attached to the movable window sash using a rope. These weights act as counterbalances, which allows you to open and close the window without requiring mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners and then turned into scrap when they break; therefore you might need to locate replacements.
A weight from a sash that fell out of the cavity is difficult to recover, so you will want to find a new one that is suitable for the. You will also require a new piece of string, a length sash cord and some sash pulleys that will tie the new sash weights the sash cord.
Older wood windows are joined by mortise and tenon joints. Hammers and pins can be used to remove the wood pegs holding the parts together. The majority of them have an enormous diameter on one side and a smaller diameter on the other, so it is essential to remove the small-diameter sides first. Later sashes used glue instead of pins. They can be separated with a knife and mallets.
After the sash is released, you can remove stops on the sash and get access to the weight pockets. This is usually done via an opening at the bottom of each jamb. The hole is then covered with an access panel of wood that can be cut off so that you can view the inside of the frame.
Once you have the sash stopped and the access panel removed, you'll be able to take off the weight of the old sash and replace it with new. Be sure to weigh the sash before you do this, since the old weights may be a different size than what you require. Once the new weight is installed you can tie a string around it and then thread it through the pulley of the sash. Then, nail the string to your boxed frame. Leave a few inches of space at the top of the string to allow for future adjustments.
Sash Cords
The majority of double-hung windows with a history have a cord or chain attached to the weights which keeps the sashes balanced in the jamb. As time passes, these cords may break, making it difficult to raise the window. A new sash cable will restore the ability to raise and lower the sash and keep it in place when it is opened.
The first step in replacing sash cords is to locate and remove the access panels in the jambs. These are usually screwed or nailed in and need to be removed. You might be able to use a hammer and chisel to prise them off, but it's always better to lay down dust sheets prior to beginning any work.

After the access panel has been removed, you can start working on the sash. Use a flat bar or chisel, to pry the tiny parting beads out of their grooves. It is essential to take your time, as these are often wedged or nailed in place. If the sash remains in place, pull the mortise-and-tenon joints out with a hammer or screwdriver and then remove each wood peg. You should be able to move the sash back and forth freely, though it might require lubrication if it feels stiff.
Measure the length of sash chain/sash cord needed to reach the sash slot on the bottom of the pulley at the top of the jamb. Cut the cord or chain and secure it as in Step 6 above. You can employ a hammer, nail or screws, but nails are less likely to cause damage.
If you don't have an upgrade kit to replace the old counterbalance system, it's best to keep the original balancing weights in place. They're not expensive and simple to install if purchased them at architectural salvage stores. Based on the size of your window one or two sashweights might be required to keep the sash in an open position.
