The sash is the internal framing that can be moved vertically up or down in windows that open. This article will show you how to make several simple sash repairs.
Weather Stripping
Wooden window sashes can add a classic look to your home. They are also durable and will last for many years if they are properly maintained. However, upvc window repairs may become damaged or deteriorate in time due to exposure to elements and normal wear and tear. Sash repair specialists can restore windows back to their original condition and maintain their beauty much longer than replacement windows.
The first step for repair sash window damage is to fix weather stripping. It's found on both the sash as well as the frame. It could cause drafts if worn out or loose. To fix it, start by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width so that you can locate replacement weather stripping to match.
Then, take it off and place it on a surface to allow access to all four sides. If your sash has a double-hung, you'll have to remove the weights and their ropes that should have fallen into the pocket of the jamb liner. After removing the sash using the utility knife, take off the weather stripping that was left by hand or using the putty blade.
After the sash is cleared, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim 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 to the bottom of the sash. Smooth the compound with your putty tool, and let it dry at least a day. Once the putty has fully dried, you can apply an acrylic latex topcoat. This will help protect the putty and give your sash a modern appearance.
Sash Hardware
The hardware that supports the windows sashes can become worn out over time and with use. This could lead to a door or a window that is difficult to open or close. The good news is that fixing and replacing this hardware is usually relatively easy and affordable. If you're having difficulty opening the sash, spray some lubricant into the jamb channel. Then, you can slide the sash out to see if this resolves the problem. If the problem persists it's likely the sash balance. You will need remove the window sash to get access to this part of the hardware.
Window sashes need to be able to open and close with minimal effort. However, this could be a challenge if the weights have been worn out or the sash connecting rail isn't properly coated. This problem could be caused by many factors that include an absence of maintenance or an unmatched weight rating.
If the hinge arms of a window are starting to lose their elasticity, this could cause the sash's to drag and eventually strike the frame in the corner opposite the hinge arm (Photo 1). To address this issue, first make sure the sash is squarely inserted into the frame's opening and then remove it from the window. If the sash has been screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Due to sagging hinges, and a general lack in energy efficiency, older windows especially in older homes, may be difficult to open or close. Many times it is a matter of making a few minor adjustments that can help these windows function smoothly once more and help homeowners save money on their energy bills.
It is crucial to have the tools needed before you start. Begin by marking the position of the hinge channel on the frame with a pencil (Photo 1). This will make it easier to position the channel in the proper position after you've finished. Remove the sash and take off the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place. Soften any hardened putty with a heat gun set to medium and fitted with an nozzle shield. Remove the old sash, and place it in a bag that is labeled.
Sash Weights
Sash weights can be changed to improve the operation of your window sash and decrease the energy cost. Sash weights are heavy, lead or iron cylinders that are enclosed in a concealed cavity and linked to the moveable sash by a rope. These weights act as counterbalances and allow you to open and shut the window without requiring mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and turned into scrap when they fail; therefore, you may need to search for replacements.
It's difficult to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also require a fresh piece of string, a length of 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 holding the components together can be removed with pin punches and hammers. The majority of these pegs have large diameters on one side and a smaller size on the other, which is why it is crucial to take out the small-diameter sides first. Sashes made later in the century used glue instead of pegs and can be separated by cutting through the glue line with an instrument, and then tapping the mortised area loose with a mallet.
After the sash has been removed, you can remove the sash stop and gain access to the weight pocket. Usually, this is done through an opening in the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the inside workings.
Once the sash is stopped and the access panel has been removed, you are able to remove the weight you used and replace it. Be sure to weigh the sash first, as the weights you have may not be the correct size. After the new weight is in place then tie a string to it and thread it through the sash pulley. Then, you can attach the string to the boxed frame. Leave a few inches of space at the top of the string to allow future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is connected to the weights. This helps keep the sashes within the jamb in a balanced manner. Over time, these chains can get damaged and render it impossible to raise windows. A new sash cable will give you the ability to move and lower the sash and keep it in position when it is opened.
The first step in replacing cords for sash is to locate and remove the access panels within the jambs. These are usually screwed or nailed into and need to be removed. It may be possible to remove them using the hammer or chisel but it is always best to lay out dust sheets before beginning any work.
After you have removed the access panel, you can begin working on the sash. Use a flat bar or chisel, to pry the tiny parting beads from their grooves. It is essential to be patient, as these are often placed in a wedge or nail. If the sash remains in place, break the mortise-and tenon joints with a screwdriver or hammer and then take out each wood peg. It should now be possible to move the sash back and forth without difficulty, though it will probably need some oil if it feels stiff.
Measure the length of sash chain/sash cord needed to reach the sash slot at the bottom of the pulley located at the top of the jamb. Cut the chain or cord and then secure it in the previous step. You can either employ a hammer and nail or screws, but nails are less likely to cause damage.
It is recommended to keep the original weights in place unless you've purchased a kit that will replace the counterbalance that was previously installed. They're not costly and simple to install if purchased them at architectural salvage stores. Based on the size of your window one or two sash weights may be needed to keep it open.
