Weather Stripping

However, they can be damaged or deteriorate as time passes due to exposure to the elements and wear and wear and tear. Thankfully, sash repair experts can bring your windows back to their original condition and maintain their appearance for a longer period of time than replacement windows.

The first step in sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It could cause drafts if worn out or loose. To fix it, start by determining your window's brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its width and height, so you can find replacement weather stripping to match.

Next, remove the sash and set it on a work surface so you can access all four sides. If your sash has been double-hung, remove the ropes and weights that should be buried inside the jamb lining. After you have removed the sash using the utility knife, remove the old weather stripping by hand or with the putty blade.

After the sash is cleared, you can install 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, but you can also use scrap wood.

After removing the parting stops and cutting them to the desired length then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty tool and let it dry at least one day. Once the putty has fully cure, you can apply a topcoat of acrylic. This will protect the putty and give your sash a new look.

Sash Hardware

The hardware that holds the windows sashes can become worn out over time and with use. This can result in a door or a window repair that is difficult to open or close. The good news is that repairing and replacing this hardware is usually very simple and cost-effective. If a sash isn't easy to operate, try spraying some lubrication into the jamb channel, and then open it to see if this fixes the problem. If not, the issue is likely with the sash balance, and you'll have to take off the sash to access this hardware.

upvc window repairs sashes need to be able to open and close with minimal effort. However, this can be a challenge if the weights have been worn out or the sash-to rail meeting rail is not properly covered with. This issue could be caused by a number of factors, including lack of maintenance or by a mismatched weight rating for the specific sash.

If the hinge arms on windows begin to slide, this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To correct the issue make sure the sash is centered in the frame opening and then take it off. If the sash has been screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

Due to hinges that are sagging, and a general lack in energy efficiency, older windows particularly those in older houses, could be difficult to open and close. In most instances, a few easy repairs can turn these windows into smooth operation again and save the homeowner money on energy bills.

In order to make these sash repairs it is important to have all the necessary tools lined up before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will help you to position the channel in the correct position after you've finished. Then, remove the sash and take off the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place. Soften any putty that has been hardened with the help of a heat gun set at medium and fitted with an shield for the nozzle. Remove the old sash and keep it in a bag with a label.

Sash Weights

Whether your window sash repairs are to replace a broken cord or just to keep the windows functional by replacing worn out sash weights will improve sash operation and reduce energy costs. Sash weights are made of heavy iron or lead cylinders that are enclosed inside a concealed cavity, and attached by a rope to the movable window sash. These weights act as counterbalances, allowing you to open and shut the window without the need for mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and turned into scrap when they break; therefore, you may need to search for replacements.

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

Older windows made of wood are joined using mortise and tenon joints. The wood pegs that keep the components together can be removed by pin punches and hammers. Most of them have large diameters on one side and a smaller size on the other, which is why it is essential to remove the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallet.

Once the sash has been released, you can remove sash stops and gain access to the weight pockets. Usually, this is done through a hole near the bottom of each jamb. This hole is then covered by a wooden access panel which can be removed to let you view the inside of the frame.

After the sash has been stopped and the access panel has been removed, you are able to remove the weight you used and replace it. Be sure to weigh the sash prior to you begin, as the weights that were previously used may be a different size than the one you need. Once the new weight is installed, you can thread the string through the sash pulling mechanism. Then, you can nail the string to the frame, but only leave a few inches of string protruding from the head for future adjustment.

Sash Cords

Most old double-hung windows come with a chain or cord connected to the weights that helps keep the sashes in balance within the jamb. Over time, these chains can become damaged and make it impossible to raise the windows. A new sash cable will restore the ability to raise and lower the sash, and keep it in position when it is opened.

The first step to replace sash cords is to find and take out the access panels located in the jambs. They are usually nailed or screwed in and must be removed or relocated. It is possible to remove them using an axe or hammer, but it is always better to lay out dust sheets before beginning any work.

Once the access panel is removed, you can begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves with a chisel or flat bar. They are usually wedged in or nailed but can be removed and it's worth your time here. If the sash remains in place, pull the mortise-and-tenon joints out with a hammer or screwdriver and then remove each wood peg. You should now be able to move the sash back and forth without difficulty, though it might require oiling if it seems stiff.

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

It is best to keep the weights that came with the original counterbalance unless you've purchased a kit to replace the counterbalance that was previously installed. It's not expensive to buy them from architectural salvage stores and they'll be simple to install once you have the sash opened. Based on the size of your window repairs near me, one or two sash weights may be needed to keep it in an open position.
