The sash is the internal frame that is vertically moved upwards or downwards in windows that open. This article will show you how to perform easy repairs to your sash.
Weather Stripping
Wood window sashes add the classic look to your home. If properly maintained, they can last for many years. However, they can become damaged or degraded in time due to exposure to elements and wear and wear and tear. Fortunately, sash repair specialists can restore your windows back to their original condition and keep them looking fantastic for much longer than newer replacement windows.
Weather stripping is the first aspect to consider when you are repairing windows that have sash. It's on both the frame and the sash. It can cause drafts if damaged or is loose. Start by identifying the brand of window and the date of manufacture for the glass (etched on the glass's corner, or the aluminum spacers between panes). Then, remove the sash and mark its height and width so that you can locate new weather stripping that matches.
Then, remove the sash from its holder, and place it on an even surface that allows you to see all four sides. If the sash is double-hung, remove the weights with their ropes that should be buried inside the jamb lining. After removing the sash using the utility knife, you can remove the weather stripping that was left by hand or with a putty knife.
When the sash is clean it is time to replace the parting stops. These are long pieces of wood that divide the two sashes. Pam prefers to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard, however you can also use a piece of scrap wood.
After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for a minimum of a day. After the putty has completely cured and dried, you can apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a fresh look.
Sash Hardware
The hardware that holds the window sashes may wear out with time and use. This can result in windows or doors that is difficult to open or close. The good thing is that fixing and replacing this hardware is usually very simple and cost-effective. If a sash is difficult to operate you can try spraying some lubrication into the jamb channel then open it to see if it resolves the issue. If not, the problem is likely with the balance of the sash and you'll need to remove the sash in order to access the hardware.
The ideal situation is for window sashes to be able to open and close with minimal effort but this can be an issue when the weights are worn or if the sash that joins rail isn't properly coated. This problem could be caused by many factors such as the lack of maintenance or an unmatched weight rating.
If pop over here of a window are beginning to lose their elasticity, this could cause the sash's to drag and eventually land on the frame in the corner that's opposite the hinge arm (Photo 1). To fix the problem, make sure that the sash is in the proper position within the frame's opening and take it off. If the sash is screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).
Old windows, particularly those in older houses, can be difficult to open and close, due to sagging hinges and general inefficiency. Many times just a few easy fixes can help these windows function smoothly and help homeowners save money on their energy bills.
To complete these sash repairs it is important to have all the necessary tools lined up before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will allow you to get the channel back in the correct position after you've finished. Then, remove the sash and take off the hardware, including the parting beads (Photo 2) and the chains or cords that secure it. The nozzle shield of the heat gun and a medium setting will soften any hardened glue. Remove the old sash and place it in a labelled bag.
Sash Weights
Whether your window sash repairs are to replace a damaged cord or just to keep your windows functioning and functional, replacing worn-out weights on sash can improve sash operation and help reduce energy consumption. Sash weights are heavy lead or iron cylinders that are enclosed in a hidden cavity and connected to the movable sash by a rope. These weights function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners and turned into scrap when they break; therefore you may have to locate replacements.
A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to locate a new one that fits correctly. You will also require a new piece of string, a length of sashcord and a few sashpulleys for tying the new weights to the cord.
Mortise and Tenon joints can be used to join older wood windows. The wood pegs that hold the parts together can be removed with pin punches and hammers. The majority of these pegs are large on one side and smaller on the other. It is crucial to first remove the smaller diameter sides. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line with an instrument, and then tapping the mortised section loose using a mallet.
After the sash is released, you can remove the sash stops and access the pockets for weights. This is typically done by drilling tiny holes at the bottom of every jamb. This hole is covered with the wooden panel which can be removed to reveal the inside workings.
After you have the sash stopped and the access panel removed, you will be able to remove the weight of the old sash and replace it with new. Make sure you weigh the sash before you do this, since the weights that were previously used may be a different size than what you require. Once the new weight is installed, tie a string to it and thread it through the pulley for the sash. Then nail the string to the frame, but only leave a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
In the majority of double-hung windows the chain or cord is attached to the weights. This keeps the sashes in the jamb level. Over time, these cords could break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash up and down 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. They are typically screwed or nailed into and require removal. You could use a hammer or chisel for removing them however, it is always best to lay down dust sheets prior to starting any work.
Once the access panel is removed, you can begin working on the sash. Utilize a flat bar, or chisel to pull the tiny partsing beads out of their grooves. It is important to take your time because they are usually stuck or nailed to the floor. If the sash is still in place, break the mortise and tenon joints using pin punch and hammer or screwdriver, and then take out the wood pegs attached to the components. The sash should be able to move freely, however it may require some lubrication to feel less stiff.
With the sash open, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot on the bottom. Cut the cord or chain and fix it using the previous step. You can either use a hammer and screws or nails, however nails are less likely to cause damage.
my response to leave the original weights in place unless you have purchased a kit to replace the counterbalance. It's cheap to purchase them from a salvage store and they will be easy to install once you've got the sash opened. Based on the size of your window two or three sash weights may be needed to keep it open.
