Weather Stripping

Wooden window sashes can add an elegant look to your home. They are also sturdy and will last for many years provided they are properly maintained. They can, however, become damaged or degraded with time, due to exposure and normal wear. Sash repair experts can restore windows to their original condition and maintain their appearance longer than replacement windows.

Weather stripping is the most important issue to take care of when fixing sash windows. It's on both the frame and the sash. If it's worn or loose, out, it can cause drafts and other problems. Begin by identifying the window brand and the date of manufacture for the glass (etched on the glass's corner or on the aluminum spacers between panes). Then, remove the sash and mark its width and height to find the appropriate weather stripping replacement to match.

Then, take it off and place it on a work surface so you can access all four sides. If your sash is double-hung, you'll have to take off the weights and the ropes that go with them that should have fallen into the pocket of the jamb liner. Once you've taken the sash off using a utility knife, you can use it to cut away the old weather stripping at the corners, then take it off by hand or with a putty knife.

When the sash is clean, you can replace the parting stops. These are long pieces that divide the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. But, you can also use a scrap piece of wood.

After removing the stoppers for parting and cutting them to the desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, and allow it to dry for at least a day. Once the putty has fully cured and dried, you can apply a topcoat of acrylic. This coating will protect the putty and give your sash a new appearance.

Sash Hardware

The hardware that supports windows sashes can become worn out with time and use. This could lead to the window or door that is difficult to open or close. It's a good idea to know that replacing or repairing this hardware is often straightforward and cost-effective. If a sash is difficult to operate try spraying grease into the jamb channel, and then open it to see if this resolves the issue. If the issue persists, it is most likely to be due to the sash's balance. It is necessary to take off the window sash in order to get access to this part of the hardware.

Ideally, window sashes must be able to open and close without effort, but this is difficult when the weights are worn or if the sash meeting rail isn't properly coated. This issue could be caused by a variety of reasons, such as lack of maintenance or by the wrong weight rating for the specific window sash.

If the hinge arms of a window are beginning to sag, this can cause the sash to slide and eventually strike the frame in the corner in the opposite direction of the hinge arm (Photo 1). To fix this problem, first ensure that the sash is firmly seated in the frame's opening and then take it out of the window. If the sash is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close due to hinges that are sagging and an overall inefficiency. In many cases it is a matter of making a few minor adjustments that can make these windows operate smoothly and save homeowners money on energy bills.

It is essential to have the tools needed before you start. Mark the hinge channel's location on the frame (Photo 1) using a pencil. This will make it easier to put the channel in the correct location after you've completed. Then, remove the sash and remove the hardware, including the parting beads (Photo 2) and the cords or chains that hold it in place. Soften any hardened putty using a heat gun set to 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 enhance the efficiency of your window sash and reduce energy costs. Sash weights are made of heavy iron or lead cylindricals that are contained inside a concealed cavity, and connected by ropes to the moveable window sash. They provide counterbalance, allowing the window to be opened and closed without using mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners and turned into scrap when they fail; therefore you may have to find replacements.

It is difficult to recover an sash-weight which has fallen from the cavity, so you'll want to find one that fits correctly. You will also require a fresh piece of string, a length sashcord and some sashpulleys to tie the new weights to the cord.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs holding the parts together can be removed by pin punches and hammers. The majority of these pegs are big on one side and smaller on the other. It is important to first remove the smaller diameter sides. Sashes that were made later in the century utilized glue instead of pegs and can be separated Near By cutting through the glue line using the help of a knife, and then tapping the mortised part loose using a mallet.

After the sash has been removed and removed, you can take off the stopper on the sash and get access to the weight pocket. This is usually done via tiny holes in the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the interior workings.

Once you have the sash stopped and the access panel removed, you will be able to take off the weight of the old sash and replace it with new. First, weigh the sash because the weights you have might not be the correct size. Once the new weight is in place, tie a string to it and thread it through the pulley of the sash. Then nail the string to the frame, but only leave a few inches of string hanging from the head for future adjustments.

Sash Cords

In the majority of double-hung windows, a cord or chain is affixed to the weights. This helps keep the sashes within the jamb balanced. As time passes, these cords may break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash up and down and will keep it in its 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 nailed or screwed in and will need to be removed or repositioned. You may be able to use a hammer and chisel for removing them but it's best to lay down dust sheets prior to commencing any work.

After removing the access panel, you can begin to work on the sash. Make the small parting beads (also called "tie rails") out of their grooves using the chisel or flat bar. It is important to take your time as they're often wedged or nailed in place. If the sash is still in place, near by break the mortise-and tenon joints with a hammer or screwdriver, then remove each wood peg. The sash should be able to move freely now, but it might require some lubrication to make it feel less stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord and fix it using the previous step. You can use either nail, hammer or screws. However, nails are less likely than screws to cause damage.

If you don't have an upgrade kit to replace the counterbalance system that was in place before, it's best to keep the original weights for balancing in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they will be easy to install once you have the sash unlocked. Depending on the size of your window one or two sashweights may be needed to keep the sash in an open position.
