Window sashes must be checked regularly for mold, mildew, and damage. If you catch these issues early, you can save money on repairs in the future.
The sash is the internal framing that can be moved vertically up or down in windows that are open. This article will demonstrate how to perform several simple repairs to the sash.
Weather Stripping
Wooden window sashes can add an elegant look to your home. They are also durable and can last many years if they are properly maintained. However, they can be damaged or deteriorate as time passes due to exposure to elements and normal wear and wear and tear. However, sash repair experts can bring your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.
The first step in sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. It can cause drafts if worn or loose. Start by identifying the window repairs near me's brand and the date of manufacture for the glass (etched on the glass's corner or on the aluminum spacers between panes). Take the sash off, and mark its width and height so that you can purchase new weather stripping that is compatible with the original.
Then, take the sash from the holder and place it on flat surfaces to allow you to access all four sides. If your sash was double-hung, you must remove the ropes and weights that should be buried within the jamb lining. Once you've taken the sash off using a utility knife, you can use it to cut off the weather stripping that was formerly in place at the corners, and then remove it manually or using a putty blade.
When the sash is clean, you can replace the parting stops. These are long pieces wood that separate 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 a piece of scrap wood.
After removing the stopper for the parting and cutting it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth the compound using your putty tool, and allow it to dry for at least a day. After it has fully dried, apply a top coat of acrylic latex paint. This will help protect the putty and give your sash a modern appearance.
Sash Hardware
The hardware that holds the windows sashes can become worn out with time and use. This could lead to the window or door that is difficult to open or close. The good news is that repairing and replacing this hardware is usually quite simple and inexpensive. If a sash becomes difficult to operate try spraying grease into the jamb channel and then open it to see if that solves the issue. If not, the problem is likely with the balance of the sash and you'll need to take out the sash in order to access the hardware.
Ideally, window sashes must swing open and closed without effort, however, this can be an issue when the weights wear out or if the sash's meeting rail isn't properly glazed. This problem could be caused by many factors, including a lack of maintenance and a mismatched weight rating.
If the hinge arms of a window are beginning to slide, this could cause the sash to drag and eventually hit the frame in the corner directly opposite the hinge arm (Photo 1). To correct the issue ensure that the sash is in the proper position within the frame opening, and then remove it. If the sash is secured to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).
Because of sagging hinges and a general lack in energy efficiency, old windows especially in older homes, may be difficult to open or close. In many cases it is a matter of making a few minor adjustments that can make these windows operate smoothly again and save homeowners money on energy bills.
To make these repairs to sash it is essential to have all of the necessary tools lined up before you begin. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will help you get the channel back on position correctly after you've completed. Remove the sash and take out all the hardware, including the beads for parting cords, chains, and cords that hold the sash in place. A hot gun with nozzle shield and medium setting will soften any hardened putty. Remove the old sash, and keep it in a bag with a label.
Sash Weights
Sash weights are able to be replaced to enhance the efficiency of your window sash and decrease the cost of energy. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and attached to the movable the sash with rope. They provide counterbalance, allowing the window to be opened and closed without the use of electrical or mechanical devices. When they fail, sashweights are usually neglected or not used by homeowners.
It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also need an additional piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights the sash cord.
Mortise and Tenon joints are used to join windows made of older wood. The wood pegs holding the components together can be removed by the use of a pin punch and hammer. Most of them have an enormous diameter on one side and a smaller diameter on the other side, so it is essential to remove the smaller-diameter sides first. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line using a knife, then tapping the mortised area loose using mallets.
After the sash has been removed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is then covered with a wooden access panel that can be cut off to allow you to view the inside of the frame.
When the sash has been shut off and the access panel is removed, you can remove the weight you used and replace it. Be sure to weigh the sash prior to you do this, since the old weights could be different in size from the one you need. Once the new weight is installed, you can thread the string through the sash pulling mechanism. Then, nail the string to your boxed frame. Leave a few inches of space at the top of the string for future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is connected to the weights. This supports and keeps the sashes within the jamb in a balanced manner. As time passes, these cords can become damaged and make it impossible to raise the windows. A new sash cord will give you the ability to move the sash up and down and will keep it in its position when it is opened.
The first step to replace sash cords is to locate and take out the access panels located in the jambs. These are usually installed by screws or nails and must be removed or repositioned. It is possible to remove them with a hammer or chisel, but it is always better to lay out dust sheets prior to starting 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's important to be patient, as these are often wedged or nailed in place. If the sash is still in place, break the mortise and tenon joints free with a hammer or screwdriver and then remove each wood peg. The sash should move freely now, but it may require some lubrication to make it feel less stiff.
With the sash in an open position, measure enough sash cord/chain to reach from the pulley on the top of the jamb to the sash slot on the bottom. Cut the chain or cord and attach it in Step 6 above. You can do this with nail, hammer or screws. However nails are less likely to cause damage.
Unless you've bought a kit that replaces the old counterbalance system it is recommended to keep the original weights for balancing in place. It's not expensive to buy them from a salvage store and they'll be easy to install once you have the sash opened. Based on the dimensions and shape of your window you may need to use one or two sashweights to keep it open.
