Window Sash Repairs

Regularly inspect the window sashes for signs of damage, mildew and mold. You can avoid future repair costs by catching the issues early on before they become too much.

The sash is an interior frame that can move upwards and downwards in windows that open. This article will show you how to do a variety of simple repairs to sash.

Weather Stripping

Wooden window sashes are a great way to add a classic look to your home. They are also sturdy and last for a long time provided they are properly maintained. However, they can be damaged or degraded over time due to exposure and normal wear and tear. Sash repair specialists can restore windows to their original state and keep them looking great longer than replacement windows.

The first step for sash window repairs is addressing weather stripping. It's found on both the sash and frame. If it's worn or loose, out, it can cause drafts and other issues. To fix it, begin by determining the brand of your window and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash, and mark its size and width so that you can get replacement weather stripping that matches.

Then, remove the sash and place it on a work surface to allow access to all four sides. If your sash has a double-hung, you'll need to remove the weights and their accompanying ropes, which should have fallen into the intended pocket in the jamb liner. After removing the sash using the utility knife, remove the old weather stripping by hand or with a putty knife.

Once the sash has been cleaned, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you can substitute a scrap piece of wood.

After removing the stoppers for parting and cutting them to the desired length and thickness, apply a thin layer of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for at least a day. Once the putty has fully cured it is possible to apply a topcoat of acrylic. This coating will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports windows sashes can become worn out over time and use. This could lead to the window or door that is difficult to open or close. It's important to know that replacing and repair of this hardware is typically straightforward and cost-effective. If a sash becomes difficult to operate, try spraying some oil into the jamb channel and then open it to see if that solves the issue. If not, the issue is likely with the sash balance and you'll need to take out the sash in order to access the hardware.

Sashes for windows should be able to be able to open and window repairs close with minimal effort. However, this could be a challenge if the weights have been worn out or the sash-to-rail meeting rail is not properly coated. This problem can be caused by a variety of factors, including the lack of maintenance or an incorrect weight rating for the specific sash.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash to drag and eventually hit the frame in the corner directly opposite the hinge arm (Photo 1). To resolve this problem, first ensure that the sash is squarely inserted into the frame's opening and then take it out of the window repairs near me. If the sash has been screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Old windows, especially those in older homes, may be difficult to open and close, due to hinges that are sagging and an overall lack of energy efficiency. In many cases, a few simple repairs can transform these windows into smooth operation again and save the homeowner money on energy costs.

To complete these repairs to sash it is essential to have all of the necessary tools in place before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will make it easier to position the channel in the proper place when you are finished. Remove the sash and take out all the hardware, including the beads for parting cords, chains, and cords that help to hold the sash. The nozzle shield of the heat gun and a medium setting can soften any putty that has been hardened. Remove the old sash, and place it in a labelled bag.

Sash Weights

If your window sash repairs are to replace a broken cord or to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and cut down on energy costs. Sash weights are heavy, lead or iron cylinders enclosed in a concealed cavity and connected to the movable the sash with a rope. These weights act as counterbalances and allow you to open and shut the window without requiring mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they fail; therefore, you may need to search for replacements.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits correctly. You will also require a new piece of string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

Older windows made of wood are joined by mortise and tenon joints. Hammers and pins can be used to remove the wood pegs that hold the parts together. The majority of these pegs are large on one side, but smaller on the other. It is important to remove first the smaller diameter sides. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting the glue line using a knife, then tapping the mortised area loose using a mallet.

After the sash is released, you can remove the sash stops and access the weight pockets. This is usually done through a small hole at the bottom of every jamb. This hole is covered by a wooden access panel that can be cut off to allow you to see the inner workings of the frame.

When the sash has been shut off and the access panel is removed, you are able to remove the old weight and replace it. Make sure you weigh the sash prior to you begin, as the old weights may be different in size from what you require. Once the new weight is in place then tie a string to it and then thread it through the pulley of the sash. Then attach the string to the boxed frame, but only leave a few inches of string sticking out from the head for future adjustments.

Sash Cords

In the majority of double-hung windows, a chain or cord is connected to the weights. This helps keep the sashes within the jamb level. Over time, these cords may become damaged and make it difficult to raise windows. A new sash cable can restore the ability to raise and lower the sash and keep it in place when it is opened.

To replace sash cords, the first step is to remove the access panels from the jambs. They are typically fixed or screwed in and must be removed or repositioned. It is possible to take them out using a hammer or chisel, but it is always better to lay out dust sheets prior to starting any work.

After you have removed the access panel, you can begin working on the sash. Utilize a flat bar, or chisel to pull the narrow parting beads out of their grooves. They are typically wedged into or nailed in, but they can be snipped out which is why it's worth your time here. If the sash is still in place, pry the mortise and tenon joints free with a screwdriver or hammer and then take out each wood peg. The sash should be able to move around freely now, however it may require some lubrication to make it feel less stiff.

Determine the length of the sash chain or sash cord needed to reach the sash slot at the bottom, and the pulley on the top of the jamb. Cut the cord or chain, and then attach it as described in Step 6 above. You can either employ a hammer, screws or nails, but nails are less likely to cause damage.

It is recommended to keep the original weights in place unless you've purchased a kit that will replace the counterbalance. It's not too expensive to purchase these from salvage shops for architectural purposes and they will be easy to install once you've got the sash unlocked. Depending on the size and shape of your window, you might need to install one or two sashweights to keep it open.
