Weather Stripping

Wood window sashes provide a classic aesthetic to your home and, when properly maintained, they will last for a long time. However, they can be damaged or degrade as time passes due to exposure to the elements and wear and tear.

To fix it, start by determining the brand of your window and the date on which the repairing glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its height and width to find the appropriate weather stripping replacement to match.

Then, remove the sash and place it on a table so you can access all four sides. If your sash has a double-hung, you'll have to remove the weights as well as the ropes that go with them which should have slipped into the pocket of the jamb liner. After removing the sash using the utility knife, take off the weather stripping from the old sash by hand or using a putty blade.

Once the sash is clear it is time to replace the parting stops. These are long pieces that separate the sashes. Pam prefers to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you can also use a piece of scrap wood.

After removing the stopper and cutting it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using your putty tool, and let it dry at least a day. Once the putty has fully cure, you can apply a topcoat of acrylic. This will protect the putty and give your sash a new look.

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 important to know that replacing and repair of this hardware is typically straightforward and cost-effective. If you are having trouble opening the sash, spray some grease into the jamb channel. Then, you can slide the sash up and open to see if it resolves the issue. If not, the issue is most likely due to the sash balance, and you'll have to take off the sash in order to access this hardware.

Ideally, window sashes must move open and shut without effort, but this is difficult if the weights become worn or if the sash's meeting rail isn't properly coated. This issue can be due to many factors that include an absence of maintenance or an unmatched weight rating.

If the hinges on windows begin to slide, this can cause the sash drag and eventually hit against the frame at the opposite corner (Photo 1). To correct the issue make sure the sash is aligned in the frame opening and then remove it. If the sash has been attached to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Due to sagging hinges, and a general lack of energy efficiency, windows that are old especially in older homes, can be difficult to open and close. Many times it is a matter of making a few minor adjustments that can help these windows function smoothly again and save homeowners money on energy bills.

In order to make these sash repairs it is important to have all of the tools needed before you begin. Begin by marking the position of the hinge channel on the frame using pencil (Photo 1). This will make it easier to put the channel in the right location after you've completed. Remove the sash, and then remove the hardware, including the parting beads (Photo 2) and the chains or cords which hold it in place. Soften any hardened putty using the help of a heat gun set at medium and fitted with an shield to block the nozzle. Remove the old sash and store it in an bag that is labeled.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or to keep the windows functional by replacing worn out sash weights will improve sash operation and cut down on energy costs. Sash weights are heavy, lead or iron cylinders that are enclosed in a concealed cavity and linked to the moveable window sash using a rope. They are counterbalancers, allowing the window to be shut and opened without using mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and then turned into scrap when they break; therefore, you may need to locate replacements.

A weight from a sash that fell out of the cavity is difficult to recover, so you will want to find a replacement that fits properly. You will also need a new piece of string, a length sash cord and some sash pulleys to tie the new sash weights the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. Hammers and pins can be used to take out the wood pegs that hold the parts together. The majority of these pegs have an enormous diameter on one side and a smaller one on the other, so it is crucial to take out the smaller-diameter sides first. Sashes made later in the century utilized glue instead of pegs and can be separated by cutting the glue line using a knife, then tapping the mortised section loose using a mallet.

Once the sash has been removed, you can take off the stops on the sash and get access to the pockets for weights. Usually this is accomplished by drilling an opening in the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the interior workings.

Once the sash is stopped and the access panel is removed, you can remove the weight that was previously installed and replace it. Weigh the sash first to ensure that the weights you have might not be the correct size. After the new weight is in place then tie a string to it and thread it through the pulley for the sash. Then, attach the string to the boxed frame. Leave a few inches of space at the top of the string to allow for future adjustments.

Sash Cords

In most old double-hung window, a cord or chain is connected to the weights. This supports and keeps the sashes within the jamb in a balanced manner. Over time, these cords could break, making it difficult to raise the window. A new sash cable can restore the ability to move and lower the sash and keep it in position when opened.

The first step to replace sash cords is to find and remove the access panels within the jambs. They are usually screwed or nailed into and require removal. You could use a hammer and chisel to prise them off however, it is always best to lay down dust sheets before starting any work.

After you have removed the access panel, you are able to begin to work on the sash. Use a flat bar or chisel to pry the small parting beads out of their grooves. It is essential to take your time because they are usually stuck or nailed to the floor. If the sash remains in place, pull the mortise and tenon joints free using a hammer or screwdriver and then take out each wood peg. The sash should move freely, however it may require some lubrication 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, and the pulley located at the top of the jamb. Cut the cord/chain and then fix it using Step 6 above. You can use nail, hammer or screws. However nails are less likely to cause damage.

It is best to keep the original weights in place unless you've purchased a kit that will replace the old counterbalance. It's not expensive to buy these from salvage shops for architectural purposes and they'll be easy to install once you've got the sash opened. Based on the dimensions and shape of your window, you may require one or two sashweights in order to keep the sash open.
