Weather Stripping

Wooden window sashes can give a classic look to your home. They are also sturdy and can last many years when they are maintained properly. However, they can become damaged or deteriorate in time because of exposure to the elements and wear and wear and tear. Fortunately, sash repair specialists can bring your windows back to their original condition and maintain their appearance for longer than replacement windows.

The first step to sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. If it's damaged or worn out, it can cause drafts and other problems. To fix it, start by determining your window'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 width and height so you can get new weather stripping that is compatible with the original.

Next, remove the sash and set it on a table to allow access to all four sides. If the sash is double-hung, you'll have to take off the weights and the ropes that go with them, which should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash using the utility knife, you can remove the weather stripping from the old sash by hand or using a putty blade.

After the sash has been cleared, you can install the parting stops. They are long pieces of wood that divide the two sashes. Pam prefers the standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also substitute with a scrap piece of wood.

After removing the stopper and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife and let it dry for at least a few days. When it's completely dried then apply a top coat of acrylic latex paint. This will protect the putty, and give your sash a fresh look.

Sash Hardware

The hardware that supports the window sashes can wear out over time and use. This can result in a door or a window that is difficult to open or close. The good news is that repairing and replacing this hardware is typically quite simple and inexpensive. If a sash isn't easy to operate you can try spraying some oil into the jamb channel and then slide it open to see if that solves the issue. If the problem persists it's likely the sash balance. It is necessary to take off the window sash to get access to this part of the hardware.

Ideally, window sashes should swing open and closed with minimal effort however, this can be a difficult task when the weights are worn or if the sash meeting rail isn't properly glazed. This issue could be caused by a number of things, such as insufficient maintenance or a mismatched weight rating for the particular window sash.

If the hinges on windows begin to slide, this could cause the sash to drag and eventually hit against the frame at the opposite corner (Photo 1). To address 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). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general lack of energy efficiency, older windows especially in older homes, may be difficult to open or close. In many cases just a few easy fixes can allow these windows to operate smoothly and save homeowners money on energy costs.

To make these sash repairs it is important to have all of the tools needed before you begin. Mark the hinge channel location on the frame (Photo 1) with pencil. This will assist you in getting the channel back on the correct position after you've finished. Remove the sash and take out all the hardware including the parting beads, cords, and chains that keep the sash in place. The nozzle shield of the heat gun and medium setting will soften any hardened putty. Take off the old sash and place it in a bag that is labeled.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and help reduce energy costs. Sash weights are composed of heavy lead or iron cylindricals that are contained in a hidden cavity and are connected via ropes to the moveable window sash. They provide counterbalance that allows the window to be closed and opened without the use of electrical or mechanical devices. The sash-weights are typically disregarded or disabled by homeowners and turned into scrap when they fail; therefore, you may need to find replacements.

It's difficult to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also require an additional piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights the sash cord.

Older wood windows are joined using mortise and tenon joints. The wood pegs holding the parts together can be removed with a pin punch and hammer. The majority of these pegs have an enormous diameter on one side and a smaller one on the other, which is why it is important to remove the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be cut with a knife and mallets.

After the sash is removed, you can take off the stops on the sash and get access to the weight pockets. Usually, this is done through a hole near the bottom of each jamb. This hole is covered by an access panel of wood that can be ripped off to let you view the inside of the frame.

After the sash has been stopped and the access panel has been removed, you can take off the weight that was previously installed and replace it. Be sure to weigh the sash prior to you do this, as the old weights may be a different size than the one you need. After the new weight is in place then tie a string to it and thread it through the pulley of the sash. Then nail the string to the frame, but leave a few inches of string sticking out from the head for future adjustment.

Sash Cords

In most old double-hung window, a chain or cord is connected to the weights. This helps keep the sashes of the jamb in a balanced manner. Over time these cords can break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash upwards and downwards and hold it in place when it is opened.

The first step in replacing sash cords is to find and remove the access panels within the jambs. These are usually nailed or screwed in and must be removed or relocated. You could use a hammer and chisel for removing them, but it's always better to lay down dust sheets prior to commencing any work.

Once the access panel is removed, you can begin working on the sash. Use a flat bar or chisel, to pry the tiny parting beads from their grooves. They are usually wedged in or nailed but can be removed and it's worth your time here. If the sash remains in place, remove the mortise and the tenon joints by using pin punch and hammer or screwdriver, and then take out the wood pegs that are on each component. The sash should be able move freely now, but it might require some lubrication in order to feel less stiff.

With the sash open, measure enough sash cord/chain to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord/chain and then attach it in the previous step. You can either employ a hammer and screws or nails, however nails are less likely to cause damage.

If you don't have an item that replaces the old counterbalance system it's recommended to keep the original balancing weights in place. They are not expensive and easy to install if you buy them from architectural salvage stores. Depending on the size of your window, one or two sashweights might be required to keep the sash in an open position.
