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 moves upwards and downwards in windows that open. This article will teach you how to perform simple sash repairs.

Weather Stripping

Wood window sashes add the classic look to your home. When properly maintained, they can last for a long time. They can, however, 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 great for a longer period of time than replacement windows.

The first step to sash window repairs is addressing weather stripping, which is found on both the sash and frame. It can cause drafts if worn or loose. To fix it, begin by determining the brand of your window and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its width and height so that you can locate new weather stripping that matches.

Then, take it off and set it on a surface to allow access to all four sides. If the sash is double-hung, take out the weights using their ropes that should fall into the pocket in the jamb lining. After removing the sash with the utility knife, you can remove the old weather stripping by hand or using a putty knife.

After the sash has been cleaned, you can replace the parting stops. These are long pieces that divide the sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also replace them with a piece of scrap wood.

After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using your putty tool and let it dry for at least one day. After the putty has completely cure, you can apply a topcoat of acrylic. This coating will protect the putty and give your sash a new appearance.

Sash Hardware

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

Ideally, window sashes must be able to open and close with very little effort, but this can be difficult when the weights are worn or if the sash meeting rail isn't properly glazed. This issue could be caused by a variety of reasons, such as insufficient maintenance or a mismatched weight rating for the specific sash.

If the hinge arms of a window are beginning to slide, this could cause the sash to drag and eventually land on the frame in the corner that's 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's opening and take it off. If the sash is screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).

Old windows, especially those in older houses, can be difficult to open and close due to sagging hinges and a general inefficiency. In many instances, a few minor repairs can turn these windows into smooth operators and save homeowners money on energy costs.

It is essential to have the tools you require before you start. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will help you get the channel back in position correctly after you've completed. Take the sash off, and remove all the hardware including the parting beads cords, chains, and cords that help to hold the sash. Soften any hardened putty using the help of a heat gun set at medium and fitted with an shield to block the nozzle. Take off the old sash and place it in a labelled bag.

Sash Weights

Sash weights are able to be replaced to improve the operation of your window sash and reduce energy costs. Sash weights are composed of heavy iron or lead cylinders that are enclosed inside a concealed cavity, and connected by ropes to the moveable window sash. These weights function as counterbalances, allowing you to open and shut the window without requiring mechanical or electrical devices. The sash weights are usually neglected or ignored by homeowners and then turned into scrap when they break; therefore you may have to locate replacements.

A weight from a sash that fell out of the cavity is difficult to recover It is therefore important to find a replacement that fits properly. You will also require a new piece string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

Mortise and Tenon joints can be used to join windows made of older wood. 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 essential to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line using the help of a knife, and then tapping the mortised section loose using a mallet.

Once the sash has been released, you can remove stops on the sash and get access to the pockets for weights. Usually, this is done through an opening at the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the interior workings.

After you have the sash stopped and the access panel removed, you'll be able to remove the old sash weight and replace it with the new. Be sure to weigh the sash prior to you do this, as the old weights may be different sizes than the one you need. After the new weight is in place you can tie a string around it and thread it through the pulley for the sash. Then, you can nail the string to the frame, but only leave a few inches of string hanging from the head for future adjustment.

Sash Cords

Most double-hung windows of the past come with a chain or cord connected to the weights that helps keep the sashes balanced in the jamb. As time passes, these cords may break, making it impossible to raise the window repairs near me. 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 to replace sash cords is to find and remove the access panels in the jambs. They are typically fixed or screwed in and must be removed or relocated. You may be able to use a hammer and chisel for removing them however, it is always 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. Utilize a flat bar, or chisel, to pry the tiny parting beads from their grooves. They are typically wedged into or nailed but can be snipped out and it's worth your time. If the sash remains in place, pry out the mortise and tenon joints using a hammer and pin punch or screwdriver, and then take out the wood pegs on each component. You should now be able to move the sash back and forth without difficulty, though it will probably need some oil if it feels stiff.

Measure the length of sash chain/sash cord needed to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the chain or cord and attach it in Step 6 above. You can use either a hammer, nails or screws. However nails are less likely to cause damage.

It's best to leave the weights that came with the original counterbalance unless you have purchased a kit that will replace the old counterbalance. They're not costly and simple to install if you purchase them from salvage shops for architectural use. Depending on the size of your window one or two sash weights might be required to keep it in an open position.
