Window Sash Repairs

Check the windows sashes regularly for damage, mildew, and mold. You can reduce the cost of repairs in the future by catching these issues early before they become too much.

The sash is an internal frame that moves upwards and downwards in windows that are open. This article will teach you how to do simple repairs to sash.

Weather Stripping

Wooden window sashes can add an elegant look to your home. They are also sturdy and last for a long time when they are maintained properly. However, misty they can become damaged or degraded in time because of exposure to the elements and normal wear and tear. Thankfully, sash repair experts can restore your windows to their original condition and keep them looking great for much longer than newer replacement windows.

Weather stripping is the primary issue to take care of when fixing windows that have sash. It's on both the frame and the sash. It could cause drafts if worn or loose. Start by identifying the brand of window repairs and the date of manufacture for the glass (etched on the glass's corners or the aluminum spacers between panes). Take the sash off, and mark its width and height so that you can get replacement weather stripping that matches.

Then, you can remove the sash from the holder and place it on an even surface that allows you to reach all four sides. If your sash is double-hung, you'll need to take off the weights and the ropes that go with them that should have fallen into the pocket of the jamb liner. After removing the sash with the utility knife, you can remove the weather stripping from the old sash by hand or using a putty knife.

Once the sash has been cleared, you can install parting stops. These are long pieces that split the sashes. Pam likes to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard, however you could also use a piece of scrap wood.

After removing the stoppers for parting and trimming them to the desired length then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using your putty tool and let it dry at least one day. When the putty is fully cure it is possible to apply an acrylic latex topcoat. This will protect the putty, and give your sash a fresh appearance.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear from the wear and tear of use, and the result can be a door or window that can't be opened or closed easily. The good news is that fixing and replacing this hardware is usually quite simple and inexpensive. If a sash becomes difficult to operate try spraying oil into the jamb channel and then open it to see if that fixes the problem. If not, the issue is likely with the sash balance, and you'll have to take off the sash in order to access the hardware.

Ideally, window sashes must move open and shut without effort, but this is difficult when the weights are worn or if the sash's meeting rail isn't properly coated. This issue can be caused by a variety of factors, including the lack of maintenance or the wrong weight rating for a particular sash.

If the hinge arms on windows begin to slide, this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To remedy the issue, make sure that the sash is centered in the frame opening and then remove it. If the sash has been screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Old windows, particularly those in older homes, can be difficult to open and close due to hinges that are sagging and an overall lack of energy efficiency. Many times, a few simple fixes can make these windows operate smoothly once more and help homeowners save money on their energy bills.

In order to make these sash repairs it is essential to have all the necessary tools lined up before you begin. Mark the hinge channel location on the frame (Photo 1) with a pencil. This will help you to place the channel in the correct position after you've finished. Take the sash off and then remove all hardware, including the beads for parting, cords, and chains that hold the sash in place. Heat gun with nozzle shield and medium setting will soften any hardened putty. Remove the old sash and put it in a bag labeled.

Sash Weights

If your window sash repairs are to replace a broken cord or just to keep the windows functional by replacing worn out weights on sash can improve sash operation and help reduce the energy cost. Sash weights are heavy lead or iron cylinders enclosed in a hidden cavity and attached to the movable the sash with a rope. These weights function as counterbalances, allowing you to open and shut the window without having to use mechanical or misty electrical devices. The sash-weights are typically disregarded or disabled by homeowners and then turned into scrap when they fail. Consequently you might need to search for replacements.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll need to find one that is suitable for the. You will also require an additional piece of string, a length of sash cord and some sash pulleys to connect the new sash weights to the sash cord.

Mortise and Tenon joints can be used to join old wood windows. Pin punch and hammer can be used to remove the wood pegs that hold the components together. The majority of them are large on one side, but smaller on the other. It is important to remove first the smaller diameter sides. Sashes made later in the century used glue instead of pegs. They can be separated by cutting the glue line using an instrument, and then tapping the mortised part loose with mallets.

Once the sash is freed, you can remove the sash stop and gain access to the weight pocket. This is typically done by drilling tiny holes in the bottom of each jamb. The hole is then covered with a wooden access panel which can be removed to allow you to see the inner workings of the frame.

Once you have the sash stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with new. Be sure to weigh the sash first, as the weights you've got may not be of the right size. After the new weight is installed, thread a string through the sash pulling mechanism. Then, attach the string to your boxed frame. Leave a few inches of space at the head of the string for future adjustments.

Sash Cords

Most double-hung windows of the past include a chain or cord attached to the weights which helps keep the sashes level within the jamb. As time passes, these cords may break, making it difficult to raise the window. A new sash cable can restore the ability to move and lower the sash, and keep it in position when it is opened.

The first step in replacing sash cords is to locate and remove the access panels within the jambs. These are usually attached by nails or screws and must be removed. You may be able to use a hammer or chisel to prise them off, but it's always better to lay down dust sheets before starting any work.

After removing the access panel, you are able to begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using the chisel or flat bar. They are typically wedged into or nailed but can be removed, so it's worth taking your time. If the sash is still in place, remove the mortise and the tenon joints by using pin punch and hammer or screwdriver, then remove the wood pegs on the components. You should now be able to move the sash back and forth freely, although it will probably need some oiling if it seems stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord and then fix it using Step 6 above. You can use either a hammer, nails or screws. However, nails are less likely to cause damage.

It is best to keep the original weights if you've purchased a kit that will replace the counterbalance that was previously installed. They're not expensive and are easy to install if you buy them at 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.
