Window sashes must be inspected regularly for signs of mold, mildew, and damage. By catching problems before they become serious you can save money on future repairs.

The sash is an inside frame that can move up and down vertically in windows that open. This article will teach you how to do easy repairs to your sash.

Weather Stripping

Wood window sashes provide the classic look to your home and, when properly maintained, can last for a long time. However, they can be damaged or degrade as time passes due to exposure to the elements and normal wear and wear and tear. Thankfully, sash repair experts can restore your windows to their original condition and maintain their appearance for longer than replacement windows.

The first step for sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It can cause drafts if it's worn out or loose. To fix it, start by determining your window's brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off, and mark its size and width so that you can get replacement weather stripping that matches.

Next, remove the sash and set it on a table to allow access to all four sides. If your sash has a double-hung, you'll need to take off the weights and their accompanying ropes, which should have fallen into the pocket that was intended to be in the jamb liner. After you've removed the sash, use a utility knife to remove the weather stripping that was formerly in place at the corners. Then, remove it manually or with a putty knife.

After the sash is cleared, you can replace the parting stops. They are long pieces of wood that separate the two sashes. Pam likes to replace these with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you can also replace them with 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 it out using your putty knife and let it dry for at least a few days. Once it's fully cured then apply a top coat of acrylic latex paint. This will protect the putty, and give your sash a modern appearance.

Sash Hardware

The hardware that supports window sashes can wear out over time and use. This could result in windows or Window repairs doors that is difficult to open or close. The good news is that fixing and replacing this hardware is usually very simple and cost-effective. If a sash isn't easy to operate try spraying oil into the jamb channel, and then slide it open to see if that resolves the issue. If not, the problem is most likely due to the balance of the sash and you'll have to take off the sash to gain access to the hardware.

The ideal situation is for window sashes to be able to open and close with minimal effort but this is an issue when the weights wear out or if the sash meeting rail isn't properly glazed. This could be caused by a variety of factors, including a lack of maintenance and an unmatched weight rating.

If the hinges on windows begin to slide, this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To fix this issue, first make sure the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash is screwed to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, old windows especially in older homes, may be difficult to open and close. In many cases, a few simple repairs can turn these windows into smooth operators again and save the homeowner money on energy bills.

In order to make these sash repairs it is essential to have all the necessary tools in place before you begin. Mark the location of the hinge channel on the frame (Photo 1) with a pencil. This will help you get the channel back in position correctly after you've completed. Remove the sash and remove the hardware including the beads that separate (Photo 2) and the chains or cords that secure it. Heat gun with nozzle shield and a medium setting will soften any hardened glue. Remove the old sash and place it in a bag with a label.

Sash Weights

Sash weights can be changed to improve the performance of your window sash, and also reduce the energy cost. Sash weights are hefty lead or iron cylinders, which are enclosed in a concealed cavity and connected to the movable window sash using rope. They provide counterbalance which allows the window to be closed and opened without the use of electrical or mechanical devices. When they fail, sashweights are often ignored or disabled by homeowners.

A weight from a sash that fell out of the cavity is difficult to recover It is therefore important to find a replacement that fits correctly. You will also require a new piece string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

Mortise and Tenon joints are used to join windows made of older wood. Pin punch and hammer can be used to cut off the wood pegs holding the parts together. The majority of these pegs are big on one side and smaller on the other. It is crucial to first remove the smaller diameter sides. Later sashes made use of glue instead of pins. They can be cut with a knife and mallets.

After the sash is removed then you can take out the stopper on the sash and get access to the weight pocket. This is usually done through an opening at the bottom of every jamb. The hole is then covered with a wooden panel that can be removed to reveal the inside workings.

After the sash has been stopped and the access panel has been removed, you can take off the weight you used and replace it. Weigh the sash first because the weights you've got may not be the right size. Once the new weight has been installed, thread a string through the sash pulling mechanism. Then nail the string to the boxed frame, leaving a few inches of string hanging from the head for future adjustments.

Sash Cords

In the majority of old double-hung windows the chain or cord is connected to the weights. This supports and keeps the sashes within the jamb balanced. As time passes, these cords may break, making it impossible to raise the window. A new sash cable can restore the ability to raise and lower the sash and keep it in place when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are usually fixed or screwed in and will need to be removed or repositioned. It may be possible to take them out using an axe or hammer, but it is always better to lay out 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 pry the tiny parting beads from their grooves. It is essential to be patient, as these are often wedged or nailed in place. If the sash is still in place, remove the mortise and tenon joints using a hammer and pin punch or screwdriver, and then take out the wood pegs attached to the components. You should now be able to move the sash around without difficulty, though it might require lubrication if it feels stiff.

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

It's best to leave the original weights if you've purchased a kit to replace the old counterbalance. They're not costly and are easy to install if purchased them from architectural salvage stores. Based on the dimensions and shape of your window, you may require one or two sashweights in order to keep it open.
