Sashes for windows must be inspected regularly for signs of mold, mildew, and damage. By catching problems before they become serious you will save money on repairs in the future.

Weather Stripping

Wood window sashes add the classic look to your home. When properly maintained, they will last for a long time. However, they can be damaged or deteriorate as time passes due to exposure to elements and normal wear and tear. Sash repair specialists can restore windows to their original state and maintain their appearance much longer than 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 could cause drafts if worn out or loose. To fix it, begin by determining your window's brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its width and height, so you can find new weather stripping that matches.

Then, remove the sash and set it on a surface so you can access all four sides. If the sash is double glazed window repairs-hung, you'll also need to take off the weights and their accompanying ropes which should have slipped into the pocket of the jamb liner. Once you've removed the sash, use a utility knife to cut away the weather stripping that was formerly in place at the corners, and then remove it by hand or with a putty knife.

Once the sash has been cleared, you can install the stoppers that separate the two sashes. These are long pieces that divide the sashes. Pam prefers the standard 1/2-inch by 3/4-inch window trimming from the lumberyard. However, you can also use a scrap piece of wood.

After removing the stopper for the parting and cutting it to length, apply a thin coat of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife, and then let it dry for a minimum of a day. When it's completely dried and dried, apply a second coat of acrylic latex paint. This will protect the putty, and give your sash a modern look.

Sash Hardware

The hardware that holds the window sashes may wear out with time and use. This could result in a door or a window that is difficult to open or close. The good news is that fixing and replacing this hardware is typically very simple and cost-effective. If you're having trouble opening a sash spray some grease into the jamb channel. Then slide the sash open to see if it resolves the problem. If not, the issue is most likely due to the sash balance and you'll need to take out the sash in order to access this hardware.

Window sashes should open and close without much effort. However, this can be difficult if the weights are worn out or the sash-to rail connecting rail isn't properly covered with. This issue can be caused by a variety of reasons, such as the lack of maintenance or the wrong weight rating for the specific sash.

If the hinge arms on the window begin to move, this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To address this problem, first ensure that the sash is squarely inserted into the opening of the frame and then take it out of the window. If the sash has been screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close due to sagging hinges and a general inefficiency. Sometimes, a few simple fixes can make these windows operate smoothly again and help homeowners save money on energy costs.

It is crucial to have the tools you need before you start. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will allow you to get the channel back on position correctly after you've completed. Then, remove the sash and take off 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 can soften any hardened putty. Remove the old sash and keep it in a bag labeled.

Sash Weights

No matter if your window sash repair needs are to replace a damaged cord or simply to keep your windows functioning and functional, replacing worn-out sash weights will improve sash operation and cut down on the energy cost. Sash weights are made of heavy iron or lead cylindricals that are contained inside a concealed cavity, and attached by ropes to the movable window sash. They are counterbalancers that allows the window to be closed and opened without the need for mechanical or electrical devices. If they fail, sashweights are often ignored or disabled by homeowners.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll need to find one that fits correctly. You will also need an additional piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights to the sash cord.

Mortise and Tenon joints are used to join windows made of older wood. The wood pegs that hold the components together can be removed using the use of a pin punch and hammer. Most of them have large diameters on one side and a smaller diameter on the other, which is why it is essential to remove the smaller-diameter sides first. Later sashes made use of glue instead of pins. They can be separated by using a knife and mallets.

Once the sash is freed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually, this is done through an opening in the bottom of each jamb. The hole is then covered with a wooden access panel that can be ripped off to let you observe the inner workings of the frame.

When the sash has been shut off and the access panel is removed, you can remove the old weight and replace it. Be sure to weigh the sash prior to you do this, since the old weights may be different in size from the one you need. Once the new weight is installed, you can thread an appropriate length of string through the pulling mechanism. Then attach the string to the frame, but only leave a few inches of string hanging from the head for future adjustments.

Sash Cords

In most old double-hung window, a cord or chain is affixed to the weights. This helps keep the sashes in the jamb in a balanced manner. As time passes, these cords can get damaged and make it difficult to raise windows. A new sash cord can restore the ability to move the sash upwards and downwards and hold it in place when it is opened.

The first step to replace cords for sash is to locate and remove the access panels in the jambs. These are usually screwed or nailed in and must be removed. You might be able to use a hammer and chisel to prise them off, but it's always better to lay down dust sheets prior to starting any work.

After the access panel has been removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using the chisel or flat bar. It is important to take your time as they're often placed in a wedge or nail. If the sash remains in place, pry out the mortise and tenon joints using the help of a hammer and pin or screwdriver, and then take out the wood pegs attached to each piece. It should now be possible to move the sash back and forth without difficulty, though it might require oil if it feels stiff.

With the sash open Take a measurement of the sash chain to reach from the pulley on the top of the jamb to the sash slot on the bottom. Cut the cord/chain and then fix it as described in Step 6 above. You can either 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 weights for balancing in place. They are not expensive and are easy to install if purchased them from salvage shops for architectural use. Based on the dimensions and shape of your window you may require one or two sashweights in order to keep the sash open.
