The first step for sash window repairs is addressing weather stripping, which can be found on both the sash and frame. It can cause drafts if it's worn out or loose.

Then, remove the sash and mark its width and height, so you can find the appropriate weather stripping replacement to match.

Then, remove the sash from the holder and place it on a flat surface to allow you to see all four sides. If your sash has a double glazed window repairs-hung, you'll have to take off the weights and their ropes, which should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash using the utility knife, take off the weather stripping from the old sash by hand or with the putty blade.

After the sash has been cleared it is time to replace the parting stops. They are long pieces of wood that are used to separate the two sashes. Pam prefers 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 stop and cutting it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth it out using your putty knife, then let it dry for a minimum of a day. After the putty has completely dried, you can apply an acrylic latex topcoat. This will help 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 result in a door or a window that is difficult to open or close. The good news is that repairing and replacing this hardware is typically relatively easy and affordable. If a sash becomes difficult to operate try spraying grease into the jamb channel then slide it open to see if that solves the issue. If the issue continues it's most likely to be due to the sash's balance. You'll need to take off the upvc window repair sash in order to access the hardware.

The ideal situation is for window sashes to be able to open and close with minimal effort but this can be a difficult task when the weights wear out or if the sash meeting rail isn't properly coated. This problem could be caused by various reasons such as the lack of maintenance or an unmatched weight rating.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash to slide and eventually land on the frame in the corner that's opposite the hinge arm (Photo 1). To fix the problem ensure that the sash is in the proper position within the frame's opening and remove it. If the sash has been screwed 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, especially those in older homes, can be difficult to open and close due to sagging hinges and a general lack of energy efficiency. In most instances, a few easy repairs can transform these windows into smooth operators again and save the homeowner cash on energy costs.

In order to make these sash repairs, it's important to have all the necessary tools in place before you begin. Mark the hinge channel's location on the frame (Photo 1) using a pencil. This will make it easier to position the channel in the right place when you are finished. Remove the sash and take out all the hardware including the parting beads cords, chains, and cords that hold the sash in place. Soften any hardened putty using an electric heat gun set to medium and fitted with a shield to block the nozzle. Remove the old sash and store it in an bag with a label.

Sash Weights

Whether your window repair sash repairs are to replace a damaged cord or simply to keep your windows functioning, replacing worn out sash weights will improve sash operation and help reduce energy consumption. Sash weights are heavy, lead or iron cylinders that are enclosed in a hidden cavity and linked to the moveable window sash using rope. They are counterbalancers which allows the window to be shut and opened without the need for mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners and then turned into scrap when they fail. Consequently you might need to search for replacements.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll want to find one that is suitable for the. You will also need a new piece of string, a length of sash cord, and a few sash pulleys to tie the new sash weights to the sash cord.

Older wood windows are joined with mortise and tenon joints. The wood pegs that keep the parts together can be removed by the use of a pin punch and hammer. Most of them have large diameters on one side and a smaller one on the other, so it is essential to remove the smaller-diameter ones first. Later sashes used glue instead of pins. They can be cut with a knife and a mallet.

Once the sash has been removed, you can take off the sash stops and access the pockets for weights. Usually it is done by drilling an opening in the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the inner workings.

After you have the sash stopped and the access panel removed, you'll be able to remove the weight of the old sash and replace it with new. Make sure you weigh the sash before you do this, as the weights that were previously used may be different sizes than what you require. After the new weight is installed, run the string through the sash pulling mechanism. Then, nail the string to your boxed frame. Leave a few inches of space at the head of the string to allow for future adjustments.

Sash Cords

Most double-hung windows of the past have a cord or chain connected to the weights that keeps the sashes balanced in the jamb. Over time these cords can break, making it impossible to raise the window. A new sash cord will restore the ability to move the sash up and down and will keep it in its position when it is opened.

The first step in replacing cords for sash is to locate and take out the access panels located in the jambs. They are usually screwed or nailed into and must be removed. You could use a hammer and chisel for removing them, but it's always better to lay down dust sheets before starting any work.

After the access panel has been removed, you can start working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves using flat bar or chisel. It is important to take your time, as these are often stuck or nailed to the floor. If the sash is in place, break the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then remove the wood pegs attached to the components. It should now be possible to move the sash around freely, though it will probably need some lubrication if it feels stiff.

Measure the length of sash cord/chain needed to reach the sash slot on the bottom of the pulley at the top of the jamb. Cut the chain or cord, and then attach it as described in the previous step. You can use a hammer, nails or screws. However, nails are less likely to cause damage.

If you haven't purchased an upgrade kit to replace the counterbalance system that was in place before, it's best to keep the original balancing weights in place. It's not expensive to buy them from a salvage store and they'll be easy to install once you have the sash open. Depending on the dimensions and shape of your window, you might need to install one or two sashweights to keep the sash open.
