The sash is an interior frame that is able to move upwards and downwards in windows that are open. This article will teach you how to do a variety of simple repairs to sash.
Weather Stripping
Wooden window sashes are a great way to add an elegant appearance to your home. They are also sturdy and will last for many years provided they are properly maintained. They may, however, get damaged or deteriorated over time, due to exposure and normal wear and tear. Fortunately, sash repair specialists can restore your windows to their original condition and keep them looking fantastic for longer than replacement windows.
Weather stripping is the primary aspect to consider when you are repairing sash windows. It's on both the frame and sash. If it's loose or worn out, it can cause drafts and other issues. Start by identifying the window brand and the manufacturer's date (etched on the corner of the glass or the aluminum spacers between panes). Then, remove the sash 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 an even surface that allows you to see all four sides. If your sash was double-hung, you must remove the ropes and weights that should be buried in the jamb lining. After you've removed the sash, use a utility knife to remove the weather stripping from the corners, and then remove it manually or with a putty knife.
Once the sash is clear it is time to replace the parting stops. These are long pieces wood that separate the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could substitute with a scrap piece of wood.
After removing the parting stop and trimming it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth out the compound using your putty knife, and then let it dry for at least a few days. Once the putty has fully cured it is possible to apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a fresh look.
Sash Hardware
The hardware that supports the window sashes may wear out over time and with use. This could lead to windows or doors that is difficult to open or close. It's good to know that replacing or fixing this hardware is usually easy and affordable. If you are having trouble opening a sash spray some oil into the jamb channel. Then, you can slide the sash out to see if it resolves the problem. If not, the issue is most likely due to the sash balance and you'll need to take out the sash in order to access this hardware.
Sashes for windows should be able to open and close without much effort. However, this may be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't properly coated. This problem can be caused by a variety of things, such as insufficient maintenance or the wrong weight rating for a particular window sash.
If the hinge arms on the window begin to move, this can cause the sash drag, and then eventually to hit the frame in the opposite corner (Photo 1). To fix the problem make sure the sash is centered in the frame opening, and then remove it. If the sash has been screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).
Old windows, particularly those in older homes, can be difficult to open and close, because of sagging hinges and a general inefficiency. In most cases, a few simple repairs can transform these windows into smooth operators for the first time and save the homeowner money on energy costs.
It is important to have the tools you need before you start. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). window repair will make it easier to put the channel in the right location after you've completed. Remove the sash, and then remove the hardware including the parting beads (Photo 2) and the chains or cords that hold it in place. Soften any putty that has been hardened with the help of a heat gun set at medium and equipped with a shield for the nozzle. Remove the old sash and store it in a bag with a label.
Sash Weights
If your window sash repairs are to replace a broken cord or to keep your windows functioning by replacing worn out sash weights will improve sash operation and help reduce the energy cost. Sash weights are made of heavy iron or lead cylinders that are enclosed in a hidden cavity and attached by a rope to the movable window sash. These weights act as counterbalances and allow you to open and close the window without the need for mechanical or electrical devices. The sash weights are usually ignored or discarded by homeowners, and are turned into scrap when they fail. Consequently you might need to find replacements.
A weight in a sash that has fallen out of the cavity is difficult to get back It is therefore important to find a new one that fits correctly. You will also require a fresh piece of string, a length sashcord and some sashpulleys to tie the weights you are replacing to the cord.
Mortise and Tenon joints can be used to join older wood windows. The wood pegs that keep the components together can be removed using pin punches and hammers. The majority of them have a large diameter on one side and a smaller size on the other, which is why it is essential to remove the small-diameter sides first. 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 stops on the sash and get access to the pockets for weights. This is typically done by drilling tiny holes in the bottom of each jamb. This hole is then covered by a wooden access panel that can be cut off so that you can see the inner workings of the frame.
When the sash has been shut off and the access panel has been removed, you can remove the weight that was previously installed and replace it. Be sure to weigh the sash prior to you do this, since the old weights may be different sizes than what you require. After the new weight is installed, run a string through the sash pulling mechanism. Then, you can nail the string to the boxed frame, but leave a few inches of string protruding from the head to allow for future adjustments.
Sash Cords
Most old double-hung windows come with a chain or cord attached to the weights which helps keep the sashes level in the jamb. Over time these cords can break, making it difficult to raise the window. A new sash cable will restore the ability to move and lower the sash, and keep it in place when opened.
The first step in replacing sash cords is to find and remove the access panels in the jambs. They are typically attached by nails or screws and need to be removed. You may be able to employ a hammer and chisel to prise them off but it's best to lay down dust sheets before beginning any work.
After you have removed the access panel, you can begin to work on the sash. Utilize a flat bar or chisel, to pry the small partsing beads out of their grooves. They are usually wedged in or nailed, but they can be removed, so it's worth taking your time here. If the sash is still in place, pull the mortise-and tenon joints with a screwdriver or hammer, then remove each wood peg. The sash should be able move freely, however it may require some lubrication in order to feel less stiff.
Take a measurement of the length of the sash chain or sash cord required to reach the sash slot at the bottom from the pulley at the top of the jamb. Cut the chain or cord and attach it in Step 6 above. You can employ a hammer and screws or nails, but nails are less likely to cause damage.
