The first step to 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 manufacturer's date (etched on the corner of the glass or the aluminum spacers between panes). Then, remove the sash and mark its width and height, so you can find replacement weather stripping to match.

Next, remove the sash and place it on a surface to allow access to all four sides. If the sash is double-hung, remove the weights with their ropes that should fall into the pocket inside the jamb lining. Once you've taken the sash off and the weights, use a utility knife to cut off the weather stripping that was formerly in place at the corners, and then take it off by hand or using a putty knife.

When the sash is clean, you can replace the parting stops. These are long pieces that divide the sashes. Pam likes to replace these with standard 1/2-inch-by 3/4-inch window trim from the lumberyard. However, you can also replace them with scrap wood.

After removing the parting stops and trimming them to the desired length then 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 one day. When the putty is fully cured, you can apply a topcoat of acrylic latex. This will help protect the putty and give your sash a modern appearance.

Sash Hardware

The hardware that supports window sashes may wear out with time and use. This could result in a door or a window that is difficult to open or close. The good news is that fixing and replacing this hardware is usually very simple and cost-effective. If you're having difficulty opening a sash, spray some grease into the jamb channel. Then, slide the sash out to see if that fixes the issue. If not, the issue is most likely due to the sash balance, and you'll have to take off the sash in order to access the hardware.

Ideally, window sashes should move open and shut with minimal effort but this is difficult when the weights are worn or window repairs if the sash that joins rail isn't properly coated. This issue can be caused by a number of things, such as insufficient maintenance or a mismatched 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 land on the frame in the corner directly opposite the hinge arm (Photo 1). To resolve this problem, first ensure that the sash is firmly seated in the opening of the frame and then remove it from the window. If the sash is secured to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

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

To complete these repairs to the sash, it's important to have all of the necessary tools in place before you begin. Mark the hinge channel's location on the frame (Photo 1) with a pencil. This will help you get the channel back into place correctly when you're finished.

Sash Weights

Whether your window sash repairs are to replace a broken cord or to keep your windows functioning, replacing worn out weights on sash can improve sash operation and cut down on the energy cost. Sash weights are composed of heavy lead or iron cylinders that are enclosed in a hidden cavity and connected by ropes to the moveable window sash. They function as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. The sash weights are usually neglected or ignored by homeowners and then turned into scrap when they break; therefore, you may need to locate replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to locate a new one that fits properly. You will also require a new piece of string, a length of sash cord and some sash pulleys to tie the new sash weights onto the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. Pin punch and hammer can be used to take out the wood pegs holding the parts together. Most of these pegs have an enormous diameter on one side and a smaller one on the other, so it is crucial to take out the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be cut by using a knife or mallets.

After the sash is removed and removed, you can take off the sash stop and access the weight pocket. This is usually done via tiny holes at the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings.

When the sash has been shut off and the access panel is removed, you can take off the weight that was previously installed and replace it. Be sure to weigh the sash first, as the weights you've got may not be the correct size. Once the new weight is in place you can tie a string around it and then thread it through the sash pulley. Then attach the string to the frame, leaving a few inches of string protruding from the head to allow for future adjustments.

Sash Cords

In the majority of old repairing double glazed windows-hung windows the chain or cord is attached to the weights. This helps keep the sashes within the jamb balanced. Over time these cords can break, making it difficult to raise the window. A new sash cable will give you the ability to raise and lower the sash, and ensure it stays in place when opened.

The first step in replacing sash cords is to find and remove the access panels within the jambs. They are usually nailed or screwed in and must be removed or relocated. You may be able to use a hammer or chisel to prise them off however, it is always best to lay down dust sheets prior to beginning any work.

After you have removed the access panel, you are able to begin to work on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves with the chisel or flat bar. They are usually wedged in or nailed in, but they can be snipped out, so it's worth taking your time here. If the sash is still in place, remove the mortise and the tenon joints by using pin punch and hammer or screwdriver, then remove the wood pegs attached to the components. The sash should be able to move freely now, but it may require some lubrication to make it feel less stiff.

With the sash in an open position With the sash in an open position, measure the sash chain or cord to reach from the pulley at the top of the jamb to the sash slot in the bottom. Cut the cord/chain, and then secure it in the step 6 above. You can employ a hammer, nail or screws, but nails are less likely to cause damage.

If you don't have an upgrade kit to replace the old counterbalance system it's best to keep the original balancing weights in place.
