Check the windows sashes regularly for signs of damage, mildew and mold. You can save future repair costs by catching the issues early on, before they get out of hand.

The sash is an internal frame that is able to move up and down vertically in windows that open. This article will teach you how to perform simple sash repairs.

Weather Stripping

Wood window sashes add the classic look to your home and, when properly maintained, they can last for many years. However, they can be damaged or degrade as time passes due to exposure to elements and normal wear and tear. However, sash repair experts can restore your windows back to their original condition and keep them looking great for much longer than newer replacement windows.

The first step for sash window repairs is addressing weather stripping, which can be found on both the sash and frame. It could cause drafts if worn out or loose. Start by identifying the brand of window and the manufacturer's date (etched on the glass's corner or the aluminum spacers between panes). Then, take the sash off and mark its width and height, so you can find replacement weather stripping to match.

Then, take the sash from its holder and place it on flat surfaces to allow you to reach all four sides. If your sash has a double-hung, you'll have to remove the weights and the ropes that go with them that should have fallen into the pocket of the jamb liner. After you've removed the sash and the weights, use a utility knife to remove the old weather stripping at the corners, and then remove it manually or with a putty knife.

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

After removing the parting stops and trimming them to your desired length then apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife and let it dry for at least a day. When it's completely dried then apply a top coat of acrylic latex paint. This will help protect the putty, and give your sash a modern appearance.

Sash Hardware

The hardware that holds the window sashes can wear out over time and use. This can result in the window or door that is difficult to open or close. It's good to know that replacing and repair of this hardware is typically easy and affordable. If you're having trouble opening a sash, spray some grease into the jamb channel. Then, slide the sash up and open to see if this resolves the issue. If not, the problem is most likely due to the balance of the sash and you'll need to remove the sash to gain access to this hardware.

Window sashes should be able to open and close with minimal effort. However, this can be difficult if weights are worn out or the sash-to-rail connecting rail isn't properly glazed. This can be due to a variety of factors, including the lack of maintenance or a mismatched weight rating.

If the hinge arms of a window repair near me begin to sag, this can cause the sash to drag and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To remedy the issue make sure the sash is aligned in the frame opening, and then remove it. If the sash is screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

Due to hinges that are sagging, and a general lack in energy efficiency, old windows especially in older houses, could be difficult to open or 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 costs.

It is crucial to have the tools needed before you begin. Begin by marking the position of the hinge channel on the frame using pencil (Photo 1). This will allow you to get the channel back on the correct position after you've finished. Take the sash off, and remove all the hardware, including the beads for parting, cords, and chains that hold the sash in place. Soften any hardened putty with an electric heat gun set to medium and equipped with a shield to block the nozzle. Remove the old sash and place it in a bag that is labeled.

Sash Weights

Sash weights are able to be replaced to enhance the efficiency of your window sash, and also reduce the cost of energy. Sash weights are composed of heavy iron or lead cylinders that are enclosed in a concealed cavity and attached by ropes to the movable window sash. They provide counterbalance, allowing the window to be opened and closed without the use of electrical or mechanical devices. The sash weights are often disregarded or disabled by homeowners and then turned into scrap when they fail. Consequently you may have to search for replacements.

A weight from a sash that fell out of the cavity is difficult to recover and you'll need to locate a new one that fits properly. You will also need an additional piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs that keep the components together can be removed with the use of a pin punch and hammer. The majority of these pegs are big on one side and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be cut by using a knife or mallets.

Once the sash has been released, you can remove stops on the sash and get access to the weight pockets. Usually it is done by drilling an opening in the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inside workings.

After you have the sash stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with the new. Weigh the sash first, as the weights you have may not be of the right size. After the new weight has been installed, you can thread a string through the sash pulling mechanism. Then, nail the string to your boxed frame. Leave a few inches of space at the end of the string for future adjustments.

Sash Cords

Most old double-hung windows come with a chain or cord attached to the weights which supports and keeps the sashes level in the jamb. Over time these cords can break, making it difficult to raise the window. A new sash cable will restore the ability to move and lower the sash, and ensure it stays in place when opened.

To replace sash cords, the first step is to remove the access panels from the jambs. They are typically attached by nails or screws and require removal. You might be able to use a hammer and chisel to prise them off but it's best to lay down dust sheets before starting any work.

After removing the access panel, you can begin to work on the sash. Utilize a flat bar, or chisel to pull the small parting beads from their grooves. They are usually wedged in or nailed but can be snipped out which is why it's worth your time here. If the sash is in place, break the mortise and tenon joints using pin punch and hammer or screwdriver, then remove the wood pegs that are on each component. You should now be able to move the sash back and forth without difficulty, though it may require lubrication if it feels stiff.

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

If you haven't purchased an item that replaces the counterbalance system that was in place before, it is recommended to keep the original balancing weights in place. They're not costly and simple to install if you purchase them from salvage shops for architectural use. Depending on the size of your window, one or two sashweights could be needed to keep it open.
