Weather Stripping

Wood window sashes add the classic look to your home. When properly maintained, can last for years. They can, however, get damaged or deteriorated over time, window repairs due to exposure and normal wear and tear. Sash repair experts can restore windows back to their original condition and maintain their appearance longer than replacement windows.

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

Then, take it off and place it on a table so you can access all four sides. If your sash has been double-hung, remove the weights using their ropes that should have fallen into the pocket inside the jamb lining. After you have removed the sash using the utility knife, remove the weather stripping from the old sash by hand or with a putty knife.

Once the sash has been cleaned, you can replace the parting stops. These are long pieces that split the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimming from the lumberyard. However, you can also use for a scrap piece of lumber.

After removing the parting stops and trimming them to the desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife, and then let it dry for a minimum of a day. Once the putty has fully cure, you can apply a topcoat of acrylic latex. This will protect the putty, and give your sash a fresh appearance.

Sash Hardware

The hardware that supports the window sashes can wear out over time and with use. This could lead to windows or doors that is difficult to open or close. It's good to know that replacing and repair of this hardware is typically simple and inexpensive. If a sash becomes difficult to operate, try spraying some oil into the jamb channel then open it to see if it fixes the problem. If not, the problem is likely to be with the sash balance, and you'll have to take off the sash to access this hardware.

Window sashes need to open and close with little effort. However, this could be difficult if the weights are worn out or the sash meeting rail is not properly glazed. This issue could be caused by a variety of reasons, such as insufficient maintenance or a mismatched weight rating for a particular sash.

If the hinges on the window begin to move, this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To resolve this issue, first make sure the sash is firmly seated in the frame's opening and then remove it from the window. If the sash is attached to the hinge arm, remove the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).

Due to hinges that are sagging, and a general lack in energy efficiency, old windows particularly those in older homes, can be difficult to open and close. In many cases, a few simple repairs can transform these windows into smooth operation for the first time and save the homeowner cash on energy costs.

To make these repairs to sash, it's important to have all of the tools needed before you begin. Mark the hinge channel's location on the frame (Photo 1) with a pencil. This will help you get the channel back into place correctly when you're finished. Take the sash off and then remove all hardware including the parting beads cords, chains, and cords that hold the sash in place. Soften any hardened putty using a heat gun set to medium and equipped with a shield for the nozzle. Remove the old sash and put it in a bag with a label.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash and reduce energy costs. Sash weights are composed of heavy iron or lead cylinders that are encased in a hidden cavity and connected by ropes to the moveable window sash. These weights function as counterbalances, allowing you to open and close the window without having to use mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they break; therefore, you may need to search for replacements.

A sash weight that has fallen out of the cavity is difficult to recover It is therefore important to find a replacement that is suitable for the. You will also require a fresh piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.

Mortise and Tenon joints are used to join windows made of older wood. Pin punch and hammer can be used to remove the wood pegs holding the components together. Most of them have an enormous diameter on one side and a smaller size on the other, which is why it is essential to remove the smaller-diameter sides first. Sashes made later in the century used glue instead of pegs. They can be separated by cutting through the glue line with a knife, then tapping the mortised part loose using a mallet.

After the sash is removed, you can take off the sash stops and access the weight pockets. Usually it is done by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inside workings.

Once the sash is stopped and the access panel is removed, you are able to remove the weight you used and replace it. Be sure to weigh the sash first because the weights you've got may not be the right size. Once the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches protruding at the top of the string to allow future adjustments.

Sash Cords

In the majority of double-hung windows the chain or cord is affixed to the weights. This supports and keeps the sashes within the jamb level. Over time, these chains may become damaged and make it difficult to raise the windows. A new sash cable will restore the ability to raise and lower the sash and keep it in position when opened.

To replace sash cords, the first step is to remove the access panels from the jambs. They are usually installed by screws or nails and will require to be removed or moved. You could employ a hammer and chisel to prise them off but it's best to lay down dust sheets before starting any work.

After removing the access panel, you are able to begin to work on the sash. Make the small parting beads (also called "tie rails") out of their grooves with flat bar or chisel. It is important to be patient as they're often wedged or nailed in place. 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 to move freely now, but it might require some lubrication in order to feel less stiff.

Take a measurement of the length of the sash chain or sash cord required to reach the sash slot on the bottom of the pulley at the top of the jamb. Cut the cord or chain and then attach it as described in Step 6 above. You can do this with a hammer, nails or screws. However, nails are less likely than screws 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 you purchase them at architectural salvage stores. Depending on the size of your window, one or two sash weights may be needed to keep it in an open position.
