Window Sash Repairs

Window sashes need to be inspected regularly for signs of mold, mildew, and damage. You can avoid the cost of repairs in the future by catching these issues in the early stages, before they become out of control.

The sash is an internal frame that is able to move upwards and downwards in windows that are open. This article will demonstrate how to carry out a few simple repairs to the sash.

Weather Stripping

Wooden window sashes can give an elegant look to your home. They are also sturdy and last for a long time if they are properly maintained. They can, however, get damaged or deteriorated over time, due to exposure and normal wear and tear. Thankfully, sash repair experts can restore your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.

Weather stripping is the primary issue to take care of when fixing windows that have sash. It's on both the frame and sash. If it's loose or worn out, it can lead to drafts, as well as other issues. To fix it, start by determining the brand of your window and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width, so you can find replacement weather stripping to match.

Then, you can remove the sash from its holder and place it on flat surfaces to allow you to reach all four sides. If your sash was double-hung, take out the weights using their ropes that should be buried within the jamb lining. After you've removed the sash using a utility knife, you can use it to cut away the weather stripping that was formerly in place at the corners. Then, remove it manually or using a putty knife.

After the sash has been cleared, you can replace parting stops. They are long pieces of wood that are used to separate the two sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you can also substitute a scrap piece of 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 with your putty tool, 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 will help protect the putty and give your sash an updated look.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear from time and usage, and the result can be a window or door that isn't able to open or close easily. It's good to know that replacing and repair of this hardware is typically easy and affordable. If you're having difficulty opening the sash, spray some oil into the jamb channel. Then slide the sash out to see if it resolves the issue. If not, the problem is likely with the sash balance, and you'll have to take off the sash in order to access the hardware.

The ideal situation is for window sashes to swing open and closed with minimal effort but this is a difficult task if the weights become worn or if the sash that joins rail isn't properly coated. This issue can be caused by a variety of reasons, such as insufficient maintenance or an incorrect weight rating for the specific sash.

If the hinge arms of a window begin to sag, this can cause the sash's to drag and eventually hit the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To correct the issue, make sure that the sash is in the proper position within the frame opening and then take it off. If the sash was attached to the hinge arm, take it off the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Due to sagging hinges, and a general lack in energy efficiency, older windows, especially those in older homes, can be difficult to open and close. In many cases, a few simple fixes can make these windows operate smoothly once more and save homeowners money on energy bills.

In order to make these sash repairs, it's important to have all of the necessary tools lined up before you begin. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will help you get the channel back in the correct position after you've finished. Take the sash off and then remove all hardware, including the parting beads cords, chains, and cords that keep the sash in place. A hot gun with nozzle shield and a medium setting can soften any putty that has been hardened. Remove the old sash, and store it in an bag with a label.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or simply to ensure that the windows are functional by replacing worn out sash weights will improve sash operation and help reduce energy consumption. Sash weights are composed of iron or lead cylindricals that are contained in a hidden cavity and connected by a rope to the movable 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 disregarded or disabled by homeowners and then turned into scrap when they break; therefore, you may need to search for near replacements.

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

Older windows made of wood are joined using mortise and tenon joints. The wood pegs that hold the components together can be removed by the use of a pin punch and hammer. Most of these pegs have an enormous diameter on one side and a smaller diameter on the other side, so it is important to remove the smaller-diameter ones first. 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 a knife, then tapping the mortised part loose using a mallet.

Once the sash has been released, you can remove sash stops and access the pockets for weights. Usually this is accomplished by drilling a hole near the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings.

After the sash has been stopped and the access panel has been removed, you are able to remove the old weight and replace it. Be sure to weigh the sash prior to you do this, as the old weights could be different in size from the one you need. 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 leave a few inches of string hanging from the head for future adjustments.

Sash Cords

The majority of double-hung windows with a history include a chain or cord attached to the weights which keeps the sashes balanced in the jamb. Over time, these cords can become damaged and render it impossible to raise the windows. A new sash cable will give you the ability to raise and lower the sash, and keep it in place when it is opened.

The first step to replace sash cords is to locate and remove the access panels in the jambs. They are typically attached by nails or screws and must be removed. You may be able to use a hammer or chisel for removing them however, it is always best to lay down dust sheets prior to starting any work.

After the access panel has been removed, you can begin working on the sash. Use a flat bar or chisel to pull the small partsing beads out of their grooves. It is important to take your time, as these are often wedged or nailed in place. If the sash remains in place, pry the mortise-and-tenon joints out using a hammer or screwdriver and then remove each wood peg. The sash should be able to move freely, however it may need some lubrication to feel less stiff.

Measure the length of sash cord/chain needed to reach the sash slot at the bottom, and the pulley on the top of the jamb. Cut the chain or cord and fix it using the previous step. You can use 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 old counterbalance system, it's best to keep the original weights for balancing in place. They are not expensive and simple to install if you buy them at architectural salvage stores. Depending on the size and shape of your window repairs near me you may need to use one or two sashweights to keep it open.
