Window Sash Repairs

Sashes for windows must be regularly checked for mold, mildew and damage. If you catch these issues early you will save money on repairs in the future.

The sash is an internal frame that can move vertically up and down in windows that open. This article will demonstrate how to perform several simple repairs to sash.

Weather Stripping

Wood window sashes add the classic look to your home and, when properly maintained, they will last for years. However, they can be damaged or degraded as time passes due to exposure to elements and wear and tear. Sash repair experts can restore windows to their original condition and maintain their appearance longer than replacement windows.

The first step in sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. It can cause drafts if damaged or is loose. To fix it, begin by finding your window brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash, window repairs and mark its width and height so that you can find a new weather stripping that is compatible with the original.

Then, remove the sash and set it on a table so you can access all four sides. If your sash is double glazing repairs near me-hung, you'll also need to take off the weights and their ropes that should have fallen into the intended pocket in the jamb liner. After you have removed the sash using the utility knife, take off the old weather stripping by hand or using a putty blade.

Once the sash is clear and clean, you can put in the parting stops. These are long pieces wood that divide the two sashes. Pam likes to replace these with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you could also use scrap wood.

After removing the parting stops and trimming them to the desired length then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for a minimum of a day. Once it's fully cured and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that holds window sashes is prone to wearing out from age and use and the result could be a window or door that can't be opened or closed easily. It's a good idea to know that replacing or repair of this hardware is typically simple and inexpensive. If you are having trouble opening a sash spray some grease into the jamb channel. Then slide the sash open to see if that fixes the issue. If not, the issue is likely with the sash balance and you'll need to take out the sash in order to access this hardware.

Window sashes should open and close without much effort. However, this could be difficult if weights are worn out or the sash meeting rail is not properly coated. This issue can be caused by a number of factors, including the lack of maintenance or an incorrect weight rating for the particular window sash.

If the hinge arms on windows begin to slide, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To resolve this issue, first make sure the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash is screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

Old windows, particularly those in older houses, can be difficult to open and close because of sagging hinges and an overall lack of energy efficiency. In many instances, a few minor repairs can transform these windows into smooth operation and save homeowners cash on energy costs.

To make these sash repairs it is essential to have all of the necessary tools lined up before you begin. Begin by marking the position of the hinge channel on the frame using pencil (Photo 1). This will allow you to get the channel back in position correctly after you've completed. Then, remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the cords or chains that secure it. Soften any hardened putty using an electric heat gun set to medium and fitted with an shield to block the nozzle. 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 to keep your windows functioning and functional, replacing worn-out weights on sash can improve sash operation and help reduce energy consumption. Sash weights consist of heavy iron or lead cylinders that are enclosed in a concealed cavity and are connected via ropes to the moveable window sash. These weights provide counterbalance, allowing the window to be shut and opened without the use of electrical or mechanical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to get back, so you will want to locate a new one that is suitable for the. You will also require a new piece of string, a length sash cord and some sash pulleys that will tie the new sash weights the sash cord.

Mortise and Tenon joints are used to join old wood windows. Hammers and pins can be used to remove the wood pegs holding the components together. The majority of these pegs are big on one side, and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated with a knife and a mallet.

After the sash is released, you can remove the sash stops and access the pockets for weights. This is typically done by drilling a small hole at the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the interior workings.

After the sash has been stopped and the access panel is removed, you can remove the old weight and replace it. First, weigh the sash, as the weights you've got may not be the right size. Once the new weight is installed, you can thread an appropriate length of string through the pulling mechanism. Then nail the string to the frame, but leave a few inches of string hanging from the head for future adjustments.

Sash Cords

In the majority of double-hung windows, a chain or cord is affixed to the weights. This keeps the sashes in the jamb balanced. Over time, these cords could break, making it impossible to raise the window. A new sash cable will give you 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 take out the access panels located in the jambs. They are usually screwed or nailed into and must be removed. It is possible to remove them using the hammer or chisel but it is always better to lay out dust sheets before starting any work.

After you have removed the access panel, you are able to begin to work on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves with flat bar or chisel. They are usually wedged in or nailed but can be removed which is why it's worth your time here. If the sash is still in place, pull the mortise and tenon joints free using a hammer or screwdriver, then remove each wood peg. It should now be possible to move the sash around without difficulty, though it will probably need some lubrication if it feels stiff.

With the sash in an open position Take a measurement of the sash chain to extend from the pulley at the top of the jamb to the sash slot in the bottom. Cut the chain or cord and attach it in the previous step. You can either employ a hammer and nail or screws, but nails are less likely to cause damage.

If you haven't purchased a kit that replaces the old counterbalance system, it's recommended to keep the original balancing weights in place. They're not costly and simple to install if purchased them from architectural salvage stores. Based on the size of your window, one or two sash weights may be needed to keep it in an open position.
