Weather Stripping

Wooden window sashes are a great way to add a classic look to your home. They are also durable and can last many years provided they are properly maintained. However, they can be damaged or degraded as time passes due to exposure to the elements and normal wear and wear and tear.

The first step for repair double glazed window sash windows is to address weather stripping, which can be found on both the sash and frame. It can cause drafts if it's worn or loose. Start by identifying the window brand and the date of manufacture for the glass (etched on the corner of the glass, or the aluminum spacers between panes). Remove the sash and mark its size and width so that you can purchase replacement weather stripping that matches.

Then, remove the sash from its holder, and place it on an even surface that allows you to reach all four sides. If the sash is double-hung, you'll need to remove the weights as well as their accompanying ropes which should have slipped 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 using a putty knife.

After the sash has been cleared and clean, you can put in the parting stops. These are long pieces of wood that are used to separate the two sashes. Pam likes to replace these with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also use a piece of scrap wood.

After removing the stoppers for parting and trimming them to the desired length and thickness, 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 at least a day. Once it's fully cured and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash an updated appearance.

Sash Hardware

The hardware that supports windows sashes can become worn out over time and use. This could result in a door repairing or a window 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 you're having difficulty opening the sash, spray some oil into the jamb channel. Then, you can slide the sash out to see if that fixes the problem. If not, the problem is likely to be with the sash balance, and you'll need to remove the sash windows repair to access this hardware.

Window sashes should open and close without much effort. However, this could be difficult if the weights are worn out or the sash-to-rail meeting rail is not properly covered with. This issue could be caused by a number of things, such as lack of maintenance or by an incorrect weight rating for the specific window sash.

If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash to slide and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To correct the issue ensure that the sash is aligned in the frame's opening and take it off. If the sash has been screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close, due to sagging hinges and an overall lack of energy efficiency. In many instances, a few minor repairs can transform these windows into smooth operation and save homeowners cash on energy costs.

It is crucial to have the tools you need before you start. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to place the channel in the proper position after you've finished. Remove the sash and take out all the hardware including the parting beads cords, chains, and cords that keep the sash in place. Heat gun with nozzle shield and medium setting will soften any hardened glue. Remove the old sash, and store it in an bag with a label.

Sash Weights

Whether your window sash repairs are to replace a broken cord or simply to keep the windows functional, replacing worn out sash weights will improve sash operation and reduce energy costs. Sash weights consist of heavy iron or lead cylindricals that are contained in a hidden cavity and are connected via 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. If they fail, sashweights are often neglected or not used by homeowners.

A sash weight that has fallen out of the cavity is difficult to recover, so you will want to find a replacement that is suitable for the. You will also require a fresh piece of string, a length sashcord and a few sashpulleys for tying the weights you are replacing to the cord.

Mortise and Tenon joints are used to join old wood windows. Hammers and pins can be used to cut off the wood pegs holding the components together. The majority of these pegs have large diameters on one side and a smaller diameter on the other, so it is essential to remove the small-diameter sides first. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting the glue line with a knife, then tapping the mortised area loose using a mallet.

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. This hole is then covered by an access panel made of wood which can be removed so that you can see the inner workings of the frame.

After the sash has been stopped and the access panel has been removed, you can remove the weight you used and replace it. First, weigh the sash, as the weights you've got may not be of the right size. After the new weight is installed, tie a string to it and then thread it through the pulley of the sash. Then, attach the string to your boxed frame. Leave a few inches protruding at the head of the string to allow for future adjustments.

Sash Cords

In the majority of old double-hung windows, a chain or cord is connected to the weights. This keeps the sashes of the jamb balanced. Over time, these cords can get damaged and render it impossible to raise the windows. A new sash cable will restore the ability to raise and lower the sash, and ensure it stays in place 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 in and need to be removed. It may be possible to remove them using an axe or hammer, however, it is best to lay out dust sheets before starting any work.

After removing the access panel, you can begin to work on the sash. Use a flat bar or chisel to pry the small parting beads from their grooves. It is essential to take your time, as these are often placed in a wedge or nail. If the sash is still in place, break the mortise and tenon joints free with a screwdriver or hammer and then take out each wood peg. It should now be possible to move the sash around freely, though it might require oil if it feels stiff.

Take a measurement of the length of sash cord/chain required to reach the sash slot at the bottom of the pulley located at the top of the jamb. Cut the cord/chain and attach it as described in the previous step. You can do this with a hammer, nails or screws. However, nails are less likely to cause damage.

It is recommended to keep the original weights in place unless you've purchased a kit to replace the counterbalance. It's not expensive to buy them from architectural salvage stores and they'll be easy to install once you have the sash open. Based on the size of your window one or two sashweights may be needed to keep the sash in an open position.
