Weather Stripping

Wood window sashes add the classic look to your home. When properly maintained, they will last for years. However, they can be damaged or deteriorate over time due to exposure to the elements and wear and wear and tear. Sash doors repair specialists can restore windows repairs to their original state and maintain their appearance longer than replacement windows.

Weather stripping is the most important issue to take care of when fixing windows that have sash. It is located on both the frame and the sash. It could 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). Then, take the sash off and mark its width and height to find the appropriate weather stripping replacement to match.

Then, you can remove the sash from the holder and place it on an even surface that allows you to reach all four sides. If your sash has been double-hung, remove the weights using their ropes that should be buried inside the jamb lining. After you've removed the sash, use a utility knife to cut off the weather stripping from the corners, and then take it off by hand or using a putty blade.

After the sash has been cleaned, you can replace the parting stops. They are long pieces of wood that are used to separate the two sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also use scrap wood.

After removing the stoppers for parting and trimming them to your desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife and let it dry for at least a day. When the putty is fully dried it is possible to apply a topcoat of acrylic. This will help protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that holds window sashes is prone to wearing out from the wear and tear of use and the result could be a window or door that isn't able to open or close easily. The good news is that repairing and replacing this hardware is generally quite simple and inexpensive. If a sash becomes difficult to operate you can try spraying some lubrication into the jamb channel, and then slide it open to see if this resolves the issue. If not, the issue is most likely due to the balance of the sash and you'll need to take out the sash in order to access the hardware.

Window sashes should open and close without much effort. However, this may be difficult if the weights are worn out or the sash-to rail meeting rail is not properly glazed. This problem can be caused by a variety of factors, including insufficient maintenance or a mismatched weight rating for the particular window sash.

If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash's to drag and eventually land on the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To remedy the issue ensure that the sash is centered in the frame opening, and then take it off. If the sash is secured to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Due to sagging hinges, and a general lack in energy efficiency, windows that are old, especially those in older houses, could be difficult to open and close. In many cases, a few simple Conservatory repairs can transform these windows into smooth operation and save homeowners money on energy bills.

It is crucial to have the tools you require before you begin. Mark the hinge channel's location on the frame (Photo 1) using pencil. This will allow you to place the channel in the proper location after you've completed. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place. Soften any hardened putty with the help of a heat gun set at medium and fitted with an nozzle shield. Remove the old sash, and put it in a bag with a label.

Sash Weights

Sash weights can be changed to improve the performance of your window sash and decrease energy costs. Sash weights are composed of heavy iron or lead cylinders that are encased in a concealed cavity and are connected via ropes to the movable window sash. They function as counterbalances, which allows you to open and close the window without requiring mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and turned into scrap when they fail; therefore you might need to find replacements.

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

Mortise and Tenon joints can be used to join older wood windows. The wood pegs that hold the components together can be removed with a pin punch and hammer. The majority of these pegs are large on one side and smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes that were made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line with an instrument, and then tapping the mortised area loose with a mallet.

After the sash has been removed then you can take out the sash stop and access the weight pocket. This is usually done through an opening in the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the interior workings.

After the sash has been stopped and the access panel removed, you will be able to remove the old sash weight and replace it with the new. Make sure you weigh the sash prior to you do this, as the old weights could be different sizes than what is needed. Once the new weight is in place then tie a string to it and then thread it through the sash pulley. Then, nail the string to the boxed frame. Leave a few inches of space at the head of the string for future adjustments.

Sash Cords

In most old double-hung window the chain or cord is connected to the weights. This keeps the sashes in the jamb in a balanced manner. Over time, these chains can get damaged and make it impossible to raise the windows. A new sash cord will give you the ability to move the sash upwards and downwards and hold it in place when it is opened.

The first step to replace cords for sash is to locate and remove the access panels within the jambs. They are usually screwed or nailed into and need to be removed. It is possible to remove them using a hammer or chisel, but it is always better to lay out dust sheets prior to beginning any work.

After removing the access panel, you can begin working on the sash. Take the narrow beads (also called "tie rails") out of their grooves with the chisel or flat bar. It is essential to be patient as they're often placed in a wedge or nail. If the sash is still in place, pull the mortise and tenon joints free with a screwdriver or hammer and then remove each wood peg. The sash should be able move around freely now, however it may require some lubrication to feel less stiff.

Measure the length of the sash chain or sash cord needed to reach the sash slot at the bottom from the pulley on the top of the jamb. Cut the cord or chain and then fix it using the step 6 above. You can do this with nail, hammer or screws. However, nails are less likely to cause damage.

Unless you've bought an item that replaces the counterbalance system that was in place before, it is recommended to keep the original weights for balancing in place. They're not costly and simple to install if purchased them from architectural salvage stores. Depending on the dimensions and shape of your window, you might need to install one or two sashweights to keep it open.
