Regularly inspect the window sashes for signs of damage, mildew and mold. You can save the cost of repairs to upvc doors in the future by catching these issues early, before they get out of hand.

The sash is an inside frame that moves up and down vertically in windows that are open. This article will teach you how to make several easy upvc repairs to your sash.

Weather Stripping

Wood window sashes add the classic look to your home and, when properly maintained, can last for years. However, they can be damaged or degraded as time passes due to exposure to elements and normal wear and tear. Sash lock repair specialists can restore windows to their original state and maintain their appearance much longer than replacement windows.

The first step in sash window repairs is addressing weather stripping, which can be found on both the sash as well as the frame. It can cause drafts if it's worn out or loose. Start by identifying the brand of window and the date of manufacture for the glass (etched on the glass repairs's corners or the aluminum spacers between panes). Then, remove the sash and mark its width and height, so you can find new weather stripping that matches.

Next, remove the sash and set it on a table so you can access all four sides. If the sash is double-hung, take out the ropes and weights that should have fallen into the pocket inside the jamb lining. After you've removed the sash and the weights, use a utility knife to cut away the old weather stripping at the corners, then take it off by hand or using a putty knife.

When the sash is clean and clean, you can put in the parting stops. These are long pieces that separate the sashes. Pam prefers standard 1/2-inch by 3/4-inch window trim from the lumberyard. But, you can substitute for a scrap piece of lumber.

After removing the stopper for the parting and trimming it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth the compound using a putty knife, and let it dry at least a day. Once it's fully cured and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports the window sashes can wear out over time and with use. This can result in the window or door that is difficult to open or close. It's good to know that replacing or fixing this hardware is usually straightforward and cost-effective. If you are having trouble opening the sash, spray some grease into the jamb channel. Then slide the sash up and open to see if that fixes the issue. If not, the problem is likely to be with the sash balance, and you'll have to take off the sash to gain access to this hardware.

Sashes for windows should be able to open and close without much effort. However, this can be difficult if weights are worn out or the sash connecting rail isn't covered with. This problem can be caused by a number of reasons, such as lack of maintenance or by an incorrect weight rating for the specific sash.

If the hinge arms of a window begin to sag, this can cause the sash to slide and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To resolve this problem, first ensure that the sash is firmly seated in the frame's opening and then remove it from the window. If the sash is secured to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Old windows, particularly those in older houses, can be difficult to open and close because of sagging hinges and a general lack of energy efficiency. In many instances, a few minor repairs can transform these windows into smooth operators and save homeowners money on energy bills.

It is important to have the tools you require before you start. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will allow you to get the channel back in place correctly when you're finished. Remove the sash and then remove all hardware, including the parting beads cords, chains, and cords that help to hold the sash. Soften any hardened putty with an electric heat gun set to medium and fitted with an shield for the nozzle. Remove the old Sash Window Repair, and put it in a labelled bag.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash and decrease the cost of energy. Sash weights are made of iron or lead cylinders that are enclosed in a hidden cavity and connected by ropes to the moveable window sash. These weights act as counterbalances, allowing you to open and shut the window without the need for mechanical or electrical devices. When they fail, sashweights are usually neglected or not used by homeowners.

A weight from a sash that fell out of the cavity is difficult to retrieve, so you will want to find a replacement that fits correctly. You will also require a new piece of string, a length the sash cord, as well as some sash pulleys to tie the new sash weights to the sash cord.

Mortise and Tenon joints are used to join old wood windows. The wood pegs that hold the parts together can be removed with the use of a pin punch and hammer. The majority of these pegs are large on one side, but smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be separated by using a knife or a mallet.

Once the sash is freed, you can remove the stopper on the sash and get access to the weight pocket. This is usually done via an opening at the bottom of every jamb. The hole is then covered with a wooden panel that can be removed to reveal the interior workings.

Once the sash is stopped and the access panel has been removed, you can remove the weight you used and replace it. Be sure to weigh the sash first, as the weights you have may not be the correct size. Once the new weight has been installed, run the string through the sash pulling mechanism. Then attach the string to the frame, leaving a few inches of string sticking out from the head for future adjustments.

Sash Cords

In most old double-hung window, a chain or cord is affixed to the weights. This keeps the sashes within the jamb in a balanced manner. 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 it is opened.

The first step to replace cords for sash is to locate and take out the access panels located in the jambs. These are usually attached by nails or screws and require removal. It is possible to remove them with an axe or hammer, but it is always best to lay out dust sheets before starting any work.

After the access panel has been removed, you can start working on the sash. Utilize a flat bar, or chisel, to pry the small partsing beads out of their grooves. It is important to be patient because they are usually wedged or nailed in place. If the sash remains in place, pry out the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then unhook the wood pegs that are on the components. You should now be able to move the sash back and forth freely, although it might require oil if it feels stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot on the bottom. Cut the cord or chain and attach it as described in Step 6 above. You can employ a hammer and screws or nails, however nails are less likely to cause damage.

If you don't have an upgrade kit to replace the counterbalance system that was in place before, it's recommended to keep the original weights for balancing in place. They're not costly and are easy to install if you buy them from salvage shops for architectural use. Depending on the size of your window, two or three sash weights could be needed to keep the sash in an open position.
