Window Sash Repairs
Regularly inspect the window sashes for signs of damage, mildew and mold. By catching problems before they become serious you can save money on future repairs.
The sash is an internal frame that can move upwards and downwards in windows that open. This article will show you how to perform several simple repairs to the sash.
Weather Stripping
Wood window sashes add the classic look to your home. When properly maintained, can last for many years. However, they can be damaged or degraded in time because of exposure to the elements and normal wear and tear. Sash repair experts can restore windows to their original condition and maintain their beauty much longer than replacement windows.
The first step in repair sash window damage is to fix weather stripping. It's found on both the sash and frame. If it's damaged or worn out, it can lead to drafts and other problems. To fix it, begin by finding your window brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its width and height, so you can find replacement weather stripping to match.
Then, remove the sash and place it on a table so you can access all four sides. If your sash is double-hung, you'll have to take off the weights and the ropes that go with them that should have fallen into the intended pocket in the jamb liner. After removing the sash with the utility knife, you can remove the weather stripping that was left by hand or with the putty blade.
After the sash is cleaned, you can replace the parting stops. These are long pieces of wood that are used to separate the two sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could substitute for a scrap piece of lumber.
After removing the parting stops and trimming them to your desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, and let it dry at least one day. When the putty is fully dried it is possible to apply a topcoat of acrylic. This will help protect the putty and give your sash an updated look.
Sash Hardware
The hardware that holds the window sashes can wear out over time and use. This could result in windows or doors that is difficult to open or close. It's good to know that replacing or repairing this hardware is often easy and affordable. If a sash isn't easy to operate try spraying grease into the jamb channel and then open it to see if it solves the issue. If not, the problem is likely to be with the balance of the sash and you'll need to remove the sash to access the hardware.
Window sashes should be able to open and close with minimal effort. However, this could be difficult if the weights are worn out or the sash-to rail meeting rail is not properly glazed. This can be due to various reasons such as the lack of maintenance or an unmatched weight rating.
If the hinge arms of a window are beginning to sag, this can cause the sash to slide and eventually strike the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To fix this problem, first ensure that the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash was fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).
Old windows, especially those in older homes, may be difficult to close and open because of sagging hinges and general inefficiency. In many instances, a few minor repairs can transform these windows into smooth operation for the first time and save the homeowner money on energy bills.
It is essential to have the tools needed before you begin. Begin by marking the position of the hinge channel on the frame using pencil (Photo 1). This will allow you to put the channel in the proper location after you've completed. Take the sash off and take out all the hardware, including the parting beads cords, chains, and cords that keep the sash in place. Soften any hardened putty with an electric heat gun set to medium and equipped with a nozzle shield. Remove window repairs near me and place it in a bag with a label.
Sash Weights
Sash weights can be replaced to enhance the efficiency of your window sash, and also reduce the cost of energy. Sash weights are made of heavy iron or lead cylindricals that are contained in a hidden cavity and connected by a rope to the movable window sash. They function as counterbalances and allow you to open and close the window without having to use mechanical or electrical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners.
A weight in a sash that has fallen out of the cavity is difficult to get back and you'll need to find a new one that fits properly. You will also require an additional piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights to the sash cord.
Mortise and Tenon joints can be used to join old wood windows. Hammers and pins can be used to remove the wood pegs that hold the parts together. The majority of them are large on one side and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be cut with a knife and mallet.
Once the sash has been removed, you can take off the sash stops and gain access to the weight pockets. This is typically done by drilling an opening at the bottom of each jamb. This hole is covered by a wooden access panel which can be removed to let you observe the inner workings of the frame.
After you have the sash stopped and the access panel removed, you'll be able to remove the old sash weight and replace it with the new. Be sure to weigh the sash first, as the weights you have might not be the correct size. Once the new weight is installed, tie a string to it and thread it through the sash pulley. Then nail the string to the frame, but only leave a few inches of string protruding from the head for future adjustment.
Sash Cords
In the majority of old double-hung windows the chain or cord is connected to the weights. This keeps the sashes in the jamb level. Over time, these chains can get damaged and render it impossible to raise the windows. A new sash cable will give you the ability to raise and lower the sash, and ensure it stays in place when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. They are typically fixed or screwed in and will need to be removed or moved. You could employ a hammer and chisel to remove them but it's best to lay down dust sheets prior to starting any work.
After the access panel has been removed, you can start working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves with a chisel or flat bar. It is essential to be patient as they're often wedged or nailed in place. If the sash is still in place, pry the mortise-and-tenon joints out using a hammer or screwdriver and then take out each wood peg. You should be able to move the sash back and forth freely, though it may require oil if it feels stiff.
Measure the length of the sash chain or sash cord required to reach the sash slot on the bottom, and the pulley on the top of the jamb. Cut the cord/chain and then secure it as in the previous step. You can employ a hammer, nail or screws, but nails are less likely to cause damage.
It's best to leave the original weights in place unless you have purchased a kit that will replace the old counterbalance. It's cheap to purchase these from salvage shops for architectural purposes and they will be easy to install once you have the sash unlocked. Depending on the size and shape of your window, you might need to install one or two sashweights to keep it open.
