Window Sash Repairs
Window sashes need to be inspected regularly for signs of mold, mildew and damage. You can avoid future repair costs by catching these issues early on before they get out of hand.
The sash is an interior frame that is able to move upwards and downwards in windows that are open. This article will teach you how to do a variety of simple repairs to the sash.
Weather Stripping
Wood window sashes give an elegant look to your home and, when properly maintained, they will last for years. They can, however, become damaged or degraded with time due to exposure or normal wear. Fortunately, sash repair specialists can restore your windows back to their original condition and keep them looking fantastic for longer than replacement windows.
The first step in repair sash window damage is to fix weather stripping, which can be found on both the sash and frame. If it's damaged or worn out, it can lead to drafts and other problems. Start by identifying the window's brand and the glass manufacturer's date (etched on the glass's corner, or the aluminum spacers between panes). Then, remove the sash and mark its height and width, so you can find new weather stripping that matches.
Then, take the sash from the holder and place it on a flat surface to allow you to access all four sides. If the sash is double-hung, you must remove the ropes and weights that should be buried inside the jamb lining. Once you've taken the sash off and the weights, use a utility knife to remove the old weather stripping at the corners. Then, remove it manually or with a putty knife.
After the sash is cleared, you can replace the stoppers that separate the two sashes. They are long pieces of wood that divide the two sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trim from the lumberyard. However, you can substitute for a scrap piece of lumber.
After removing the parting stops 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 a putty knife, and allow it to dry for at least one day. When the putty is fully cured, you can apply a topcoat of acrylic. This will protect the putty and give your sash a new look.
Sash Hardware
The hardware that supports window sashes susceptible to wear and tear from age and use, and the result can be a door or window that won't open or close easily. It's a good idea to know that replacing or repair of this hardware is typically straightforward and cost-effective. If you're having difficulty opening the sash, spray some lubricant into the jamb channel. Then, you can slide the sash out to see if it resolves the problem. If not, the problem is likely to be with the sash balance and you'll need to take out the sash to gain access to this hardware.
Window 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 covered with. This can be due to a variety of factors, including a lack of maintenance and a mismatched weight rating.
If the hinges on windows begin to slide, this could cause the sash to drag, and then eventually to hit the frame at the opposite corner (Photo 1). To address this issue, first make sure the sash is squarely inserted into the frame's opening and then remove it from the window. If the sash is screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).
Old windows, especially those in older homes, may be difficult to open and close due to sagging hinges and a general inefficiency. In most instances, a few easy repairs can turn these windows into smooth operation for the first time and save the homeowner cash on energy costs.
It is important to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) using a pencil. This will help you get the channel back on position correctly after you've completed. Remove the sash, and remove all the hardware including the parting beads cords, chains, and cords that keep the sash in place. Soften any hardened putty using a heat gun set to medium and fitted with a shield to block the nozzle. Take off the old sash and put it in a bag that is labeled.

Whether your window sash repairs are to replace a broken cord or to keep the windows functional, replacing worn out weights on sash can improve sash operation and cut down on the energy cost. Sash weights are composed of heavy lead or iron cylinders that are encased inside a concealed cavity, and connected by a rope to the movable window sash. These weights act as counterbalances, allowing you to open and shut the window without requiring mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners and then turned into scrap when they fail; therefore, you may need to search for replacements.
A weight in a sash that has fallen out of the cavity is difficult to retrieve and you'll need to locate a new one that fits properly. You will also require a fresh piece of 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 older wood windows. The wood pegs holding the parts together can be removed by a pin punch and hammer. Most of them have large diameters on one side and a smaller diameter on the other, so it is essential to remove the smaller-diameter ones first. Sashes made later in the century used glue instead of pegs. They can be separated by cutting the glue line using the help of a knife, and then tapping the mortised part loose using mallets.
Once the sash is freed then you can take out the sash stop and access the weight pocket. This is usually done via an opening in the bottom of each jamb. This hole is covered with the wooden panel which can be removed to reveal the interior workings.
When the sash has been shut off and the access panel is removed, you are able to remove the weight you used and replace it. Make sure you weigh the sash before you do this, since the old weights could be a different size than what is needed. After the new weight is installed, you can thread the string through the sash pulling mechanism. Then attach the string to the boxed frame, leaving a few inches of string sticking out from the head for future adjustment.
Sash Cords
In the majority of double-hung windows, a cord or chain is attached to the weights. This supports and keeps the sashes within the jamb level. Over time these cords can break, making it difficult to raise the window. A new sash cable will 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 locate and remove the access panels within the jambs. They are usually attached by nails or screws and require removal. You might be able to use a hammer and chisel to remove them but it's best to lay down dust sheets before beginning any work.
Once the access panel is removed, you can start working on the sash. Use a flat bar or chisel to pull the small parting beads out of their grooves. They are usually wedged in or nailed in, but they can be prised free, so it's worth taking your time here. If the sash is in place, remove the mortise and tenon joints using the help of a hammer and pin or screwdriver, then remove the wood pegs that are on each piece. The sash should move freely, however it may require some lubrication to feel less stiff.
Determine the length of sash cord/chain needed to reach the sash slot at the bottom from the pulley at the top of the jamb. Cut the cord/chain and then attach it in the previous step. You can use a hammer, nails or screws. However, nails are less likely to cause damage.
If you don't have an upgrade kit to replace the old counterbalance system it's recommended to keep the original balancing weights in place. They're not expensive and easy to install if purchased them at architectural salvage stores. Depending on the size and shape of your window you may need to use one or two sashweights to keep the sash open.
