Window Sash Repairs

Sashes for windows must be inspected regularly for signs of mold, mildew, and damage. By catching these problems early you will save money on future repairs.

The sash is an interior frame that is able to move vertically up and down in windows that open. This article will teach you how to perform several simple repairs to sash.

Weather Stripping

Wood window sashes give the classic look to your home. When properly maintained, they can last for many years. They can, however, become damaged or degraded with time due to exposure or normal wear and tear. Thankfully, sash upvc repair experts can restore your windows to their original condition and maintain their appearance 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. It can cause drafts if it's damaged or is loose. Start by identifying the brand of window and the manufacturer's date (etched on the glass's corner or on 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, take it off and set it on a work surface so you can access all four sides. If the sash is double glazing (http://www.Gabiz.kr/g5/bbs/board.php?bo_table=Free&wr_Id=1545968)-hung, you must remove the ropes and weights that should be buried within the jamb lining. After you've removed the sash, use a utility knife to cut away the weather stripping from the corners. Then, take it off by hand or using a putty knife.

Once the sash has been cleaned, you can replace the stoppers that separate the two sashes. These are long pieces that separate the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trimming from the lumberyard. But, you can substitute for a scrap piece of lumber.

After removing the parting stops and cutting them to the desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife, and then let it dry for at least a few days. When it's completely dried, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new look.

Sash Hardware

The hardware that holds the window sashes can wear out over time and use. This can result in windows or doors that is difficult to open or close. It's a good idea to know that replacing and repairing this hardware is often straightforward and cost-effective. If a sash is difficult to operate you can try spraying some oil into the jamb channel then open it to see if that solves the issue. If not, the issue is likely with the balance of the sash and you'll need to take out the sash to gain access to the hardware.

Ideally, window sashes should move open and shut without effort, but this is a difficult task if the weights become worn or if the sash's meeting rail isn't properly glazed. This could be caused by a variety of factors that include an absence of maintenance or an unmatched weight rating.

If the hinge arms of a window are beginning to slide, this could cause the sash to slide and eventually hit the frame in the corner opposite the hinge arm (Photo 1). To fix this issue, first make sure the sash fits squarely in the opening of the frame and then remove it from the window. If the sash is fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Due to sagging hinges, and a general lack of energy efficiency, old windows particularly those in older homes, may be difficult to open or close. In many instances, a few minor repairs can turn these windows into smooth operation again and save the homeowner money on energy costs.

In order to make these sash repairs it is essential to have all of the necessary tools lined up before you begin. Mark the hinge channel's location on the frame (Photo 1) with a pencil. This will assist you in getting the channel back in the correct position after you've finished. Then, remove the sash and remove the hardware including the parting beads (Photo 2) and the chains or cords that secure it. A hot gun with nozzle shield and a medium setting will soften any hardened putty. Take off the old sash and keep it in a bag labeled.

Sash Weights

Sash weights are able to be replaced to enhance the efficiency of your window sash and decrease energy costs. Sash weights consist of heavy iron or lead cylinders that are enclosed in a concealed cavity and attached by ropes 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 from a sash that fell out of the cavity is difficult to retrieve, so you will want to find a new one that fits correctly. You will also need an additional piece of string, a length sash cord, and a few sash pulleys that will tie the new sash weights the sash cord.

Older wood windows are joined by mortise and tenon joints. The wood pegs that hold the parts together can be removed with the use of a pin punch and hammer. The majority of them have large diameters on one side and a smaller one on the other, which is why it is essential to remove the small-diameter sides first. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line using the help of a knife, and then tapping the mortised section loose with mallets.

After the sash is removed, you can remove the stopper on the sash and get access to the weight pocket. This is usually done through a small hole at the bottom of each jamb. The hole is then covered with an access panel of wood which can be removed so that you can view the inside of the frame.

After the sash has been stopped and the access panel is removed, you can take off the weight that was previously installed and replace it. Weigh the sash first because the weights you have may not be the correct size. Once the new weight has been installed, you can thread the string through the sash pulling mechanism. Then, you can 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, a chain or cord is affixed to the weights. This helps keep the sashes within the jamb level. Over time, these cords could break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash upwards and downwards and keep it in place when opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are typically attached by nails or screws and require removal. It may be possible to remove them using a hammer or chisel, but it is always better to lay out dust sheets prior to starting any work.

Once the access panel is removed, you can start working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with the chisel or flat bar. 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 screwdriver or hammer, then remove each wood peg. You should now be able to move the sash back and forth freely, although it may require oiling if it seems stiff.

Determine the length of the sash chain or sash cord required to reach the sash slot on the bottom from the pulley located at the top of the jamb. Cut the chain or cord and attach it in the previous step. You can use a hammer and screws or nails, however nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the old counterbalance system it's recommended to keep the original balancing weights in place. They are not expensive and are easy to install if purchased them from salvage shops for architectural use. Based on the size of your window, one or two sashweights may be needed to keep it open.
