Window Sash Repairs

Window sashes need to be inspected regularly for signs of mold, mildew and damage. If you catch these issues early, you can save money on repairs in the future.

The sash is an internal frame that is able to move upwards and downwards in windows that are open. This article will show you how to carry out a few simple repairs to the sash.

Weather Stripping

Wooden window sashes are a great way to add an elegant look to your home. They are also sturdy and will last for many years when they are maintained properly. However, they can be damaged or deteriorate in time because of exposure to the elements and normal wear and tear. Sash repair specialists can restore windows to their original state and keep them looking great longer than replacement windows.

The first step in sash window repairs is addressing weather stripping, which can be found on both the sash and frame. It could cause drafts if worn or loose. Begin by identifying the window's brand and the glass manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Remove the sash and mark its width and height so that you can get replacement weather stripping that matches.

Then, you can remove the sash from its holder and place it on a flat surface to allow you to access all four sides. If your sash has been double-hung, remove the ropes and weights that should fall into the pocket in the jamb lining. Once you've removed the sash, use a utility knife to cut off the weather stripping that was formerly in place at the corners, and then remove it by hand or using a putty blade.

After the sash has been cleared, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers to replace them 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 your desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using a putty tool and let it dry at least one day. When the putty is fully dried and dried, you can apply a topcoat of acrylic latex. This will protect the putty and give your sash a new look.

Sash Hardware

The hardware that holds the windows sashes can become worn out over time and use. This could lead to a door or a window that is difficult to open or close. It's important to know that replacing and repairing this hardware is often straightforward and cost-effective. If you're having trouble opening the sash, spray some lubricant into the jamb channel. Then slide the sash open to see if that fixes the problem. If not, the issue is likely to be with the balance of the sash and you'll have to take off the sash in order to access the hardware.

window repair sashes need to open and close with little effort. However, this may be difficult if weights are worn out or the sash-to-rail connecting rail isn't coated. This could be caused by many factors that include the lack of maintenance or a mismatched weight rating.

If the hinge arms on the window begin to move, this could cause the sash to 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 remove it from the upvc window repairs. If the sash has been attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).

Old windows, particularly those in older homes, may be difficult to close and open due to hinges that are sagging and general lack of energy efficiency. In many instances, a few easy repairs can turn these windows into smooth operators for the first time and save the homeowner cash on energy costs.

It is essential to have the tools you need before you begin. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will help you to place the channel in the right location after you've completed. 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. Soften any hardened putty using a heat gun set to medium and fitted with an shield to block the nozzle. Take off the old sash and keep it in a bag with a label.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash, and also reduce the cost of energy. Sash weights are heavy lead or iron cylinders, which are enclosed in a concealed cavity and linked to the moveable window sash using a rope. These weights provide counterbalance which allows the window to be shut and opened without the need for mechanical or electrical devices. If they fail, sashweights are usually ignored or disabled by homeowners.

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

Mortise and Tenon joints can be used to join old wood windows. The wood pegs that keep the components together can be removed using pin punches and hammers. The majority of these pegs are big on one side, and smaller on the other. It is important to remove first the smaller diameter sides. Sashes made later in the century utilized glue instead of pegs and can be separated by cutting the glue line with the help of a knife, and then tapping the mortised area loose with mallets.

Once the sash has been released, you can remove stops on the sash and get access to the pockets for weights. This is usually done through an opening at the bottom of each jamb. This hole is covered with an unfinished 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 old weight and replace it. Be sure to weigh the sash first to ensure that the weights you've got may not be the right size. Once the new weight is installed, you can thread the string through the sash pulling mechanism. Then, attach the string to the boxed frame. Leave a few inches at the end of the string to allow future adjustments.

Sash Cords

The majority of double-hung windows with a history have a cord or chain connected to the weights that supports and keeps the sashes in balance in the jamb. Over time, these cords could break, making it impossible to raise the window repairs. A new sash cord will restore the ability to move the sash up and down and hold it in place when opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are typically attached by nails or screws and need to be removed. You may be able to use a hammer or chisel to prise them off but it's best to lay down dust sheets prior to commencing any work.

After you have removed the access panel, you are able to begin working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with the chisel or flat bar. These are often wedged in or nailed but can be prised free which is why it's worth your time. If the sash remains in place, pull the mortise-and tenon joints using a hammer or screwdriver, then remove each wood peg. You should now be able to move the sash back and forth without difficulty, though it will probably need some lubrication if it feels stiff.

Take a measurement of the length of sash chain/sash cord needed to reach the sash slot at the bottom of the pulley on the top of the jamb. Cut the cord/chain and then fix it using Step 6 above. You can use a hammer and nail or screws, but nails are less likely to cause damage.

If you don't have a kit that replaces the counterbalance system that was in place before, it is recommended to keep the original balancing weights in place. It's not expensive to buy them from a salvage store and they will be easy to install once you have the sash unlocked. Depending on the size of your window, one or two sashweights may be needed to keep it open.
