The sash is the interior frame that is vertically moved upwards or downwards in windows that open. This article will show you how to do simple sash repairs.

Weather Stripping

Wood window sashes add an elegant look to your home. If properly maintained, they can last for many years. However, they can become damaged or degraded with time, due to exposure and normal wear. However, sash repair experts can bring your windows back to their original condition and keep them looking fantastic for much longer than newer replacement windows.

The first step to sash window repairs is addressing weather stripping, which can be found on both the sash and frame. If it's damaged or worn out, it can cause drafts, as well as other issues. Begin by identifying the window's brand and the manufacturer's date (etched on the glass's corners or on the aluminum spacers between panes). Then, take the sash off and mark its height and width to find new weather stripping that matches.

Then, remove the sash and set it on a surface so that you can reach all four sides. If the sash is double-hung, you'll need to remove the weights and their accompanying ropes which should have slipped into the pocket that was intended to be in the jamb liner. After removing the sash using the utility knife, take off the weather stripping from the old sash by hand or with the putty blade.

After the sash has been cleared, you can replace the parting stops. These are long pieces that separate 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 scrap wood.

After removing the parting stops and cutting them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool and let it dry for at least one day. When the putty is fully dried and dried, you can apply a topcoat of acrylic latex. This will help protect the putty and give your sash an updated appearance.

Sash Hardware

The hardware that supports windows sashes can become worn out with time and use. This could lead to windows or doors that is difficult to open or window repair (www.repairmywindowsanddoors.co.uk) close. It's good to know that replacing and fixing this hardware is usually straightforward and cost-effective. If you're having difficulty opening the sash, spray some lubricant into the jamb channel. Then slide the sash open to see if this resolves the issue. If not, the problem is likely with the balance of the sash and you'll need to remove the sash to gain access to this hardware.

Window sashes need to be able to open and close with minimal effort. However, this can be difficult if the weights are worn out or the sash meeting rail is not properly coated. This issue can be due to various reasons such as a lack of maintenance and an unmatched weight rating.

If the hinge arms of a window begin to sag, this can cause the sash to drag and eventually land on the frame in the corner in the opposite direction of the hinge arm (Photo 1). To correct the issue, make sure that the sash is in the proper position within the frame opening, and then remove it. If the sash was screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Due to hinges that are sagging, and a general lack of energy efficiency, windows that are old particularly those in older homes, can be difficult to open and close. In most cases, a few simple repairs can turn these windows into smooth operators for the first time and save the homeowner money on energy bills.

It is crucial to have the tools needed before you start. Begin by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will allow you to position the channel in the correct place when you are finished. Then, remove the sash, and then remove the hardware, including the parting beads (Photo 2) and the chains or cords which hold it in place. A hot gun with nozzle shield and a medium setting will soften any putty that has been hardened. Take off the old sash and place it in a bag with a label.

Sash Weights

Sash weights are able to be replaced to improve the performance of your window sash and decrease the energy cost. Sash weights are made of heavy iron or lead cylinders that are encased inside a concealed cavity, and attached by ropes to the movable window sash. They function as counterbalances, allowing you to open and shut the window without requiring mechanical or electrical devices. The sash weights are usually ignored or discarded by homeowners and then turned into scrap when they fail; therefore you may have to find replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to find a new one that fits correctly. You will also require a new piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. Hammers and pins can be used to take out the wood pegs holding the parts together. Most of them have an enormous diameter on one side and a smaller diameter on the other side, so it is crucial to take out the small-diameter sides first. Sashes made later in the century used glue instead of pegs and 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 and removed, you can take off the stopper on the sash and get access to the weight pocket. This is usually done through a small hole in the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings.

After the sash has been stopped and the access panel has been removed, you can remove the old weight and replace it. Be sure to weigh the sash before you begin, window repairs as the weights that were previously used may be different sizes than what is needed. After the new weight is installed, tie a string to it and then thread it through the pulley of the sash. Then, nail the string to the boxed frame. Leave a few inches at the top of the string for future adjustments.

Sash Cords

In most old double-hung window, a chain or cord is affixed to the weights. This helps keep the sashes of the jamb in a balanced manner. Over time these cords can break, making it impossible to raise the window. A new sash cable will restore the ability to raise and lower the sash and ensure it stays in place when opened.

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

Once the access panel is removed, you can start working on the sash. Take the narrow beads (also called "tie rails") out of their grooves with flat bar or chisel. It is important to take your time, as these are often stuck or nailed to the floor. If the sash is still in place, pry the mortise-and tenon joints using a hammer or screwdriver, then remove each wood peg. The sash should be able to move freely now, but it may need some lubrication in order to feel less stiff.

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

It is recommended to keep the weights that came with the original counterbalance unless you have purchased a kit to replace the counterbalance that was previously installed. They're not costly and easy to install if you buy them from architectural salvage stores. Depending on the size and shape of your window you may require one or two sashweights to keep it open.
