Window sashes need to be checked regularly for mold, mildew and damage. You can reduce the cost of repairs in the future by catching these issues early on before they become too much.

Weather Stripping
Wooden window sashes can give an elegant appearance to your home. They are also durable and last for a long time if they are properly maintained. However, they can become damaged or deteriorate as time passes because of exposure to the elements and normal wear and wear and tear. Sash repair specialists can restore windows back to their original condition and Window Repairs maintain their appearance longer than replacement windows.
The first step in sash window repairs is addressing weather stripping, which can be found on both the sash and frame. It could cause drafts if damaged or is loose. Start by identifying the upvc window repair brand and the manufacturer's date (etched on the glass's corner, or the aluminum spacers between panes). Take the sash off, and mark its width and height so you can purchase replacement weather stripping that matches.
Then, remove the sash and place it on a work surface so you can access all four sides. If the sash is double-hung, you must remove 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 off the old weather stripping at the corners. Then, take it off by hand or with a putty knife.
Once the sash has been cleared, you can replace parting stops. They are long pieces of wood that divide the two sashes. Pam likes to replace these with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, but you could also use a piece of scrap wood.
After removing the stopper and cutting it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for at least a day. When the putty is fully dried, you can apply a topcoat of acrylic latex. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that holds the windows sashes can become worn out with time and use. This could lead to the window or door that is difficult to open or close. The good news is that repairing and replacing this hardware is generally very simple and cost-effective. If a sash isn't easy to operate, try spraying some oil into the jamb channel then slide it open to see if this resolves the issue. If the issue continues, it is most likely the sash balance. You'll need to take off the window sash to access the hardware.
Ideally, window sashes must move open and shut without effort, however, this can be an issue when the weights are worn or if the sash meeting rail isn't properly coated. This issue can be caused by a number of reasons, such as lack of maintenance or by a mismatched weight rating for the particular sash.
If the hinge arms of a window begin to lose their elasticity, this could cause the sash's to drag and eventually hit the frame in the corner opposite the hinge arm (Photo 1). To remedy the issue ensure that the sash is aligned in the frame opening, and then take it off. If the sash has been screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, older windows particularly those in older homes, may be difficult to open or close. Sometimes, a few simple fixes can make these windows operate smoothly and help homeowners save money on their energy bills.
It is important to have the tools you need before you start. Mark the location of the hinge channel on the frame (Photo 1) with pencil. This will make it easier to place the channel in the right position after you've finished. Remove the sash, and remove all the hardware, including the beads for parting, cords, and chains that keep the sash in place. Soften any hardened putty with a heat gun set to medium and equipped with an shield for the nozzle. Remove the old sash and place it in a bag that is labeled.
Sash Weights
If your window sash repairs are to replace a damaged cord or simply to keep your windows functioning, replacing worn out weights for sash will improve its operation and reduce energy costs. Sash weights are heavy lead or iron cylinders that are enclosed in a hidden cavity and linked to the moveable the sash with rope. These weights function as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners and then turned into scrap when they fail; therefore you may have to locate replacements.
It's difficult to retrieve the sash-weight that fell from the cavity, so you'll want to find one that is suitable for the. You will also require a new piece of string, a length of the sash cord, as well as some sash pulleys to tie the new sash weights onto the sash cord.
Mortise and Tenon joints are used to join old wood windows. The wood pegs that keep the parts together can be removed with the use of a pin punch and hammer. Most of these pegs have a large diameter on one side and a smaller size on the other side, so it is crucial to take out the smaller-diameter ones first. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line using an instrument, and then tapping the mortised section loose with mallets.
Once the sash has been released, you can remove sash stops and gain access to the weight pockets. Usually it is done by drilling a hole near the bottom of each jamb. This hole is covered by an access panel made of wood that can be ripped off to let you observe the inner workings of the frame.
Once 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 because the weights you've got may not be the right size. After the new weight has been installed, you can thread an appropriate length of string through the pulling mechanism. Then, attach the string to your boxed frame. Leave a few inches at the head of the string for future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is attached to the weights. This helps keep the sashes of the jamb in a balanced manner. Over time, these cords may become damaged and make it impossible to raise the windows. A new sash cord will give you the ability to move the sash up and down and hold it in place when it is opened.
The first step in replacing cords for sash is to locate and remove the access panels in the jambs. They are usually attached by nails or screws and must be removed. You could employ a hammer and chisel to prise them off, but it's always better to lay down dust sheets before beginning any work.
After the access panel has been removed, you can start working on the sash. Take the narrow beads (also called "tie rails") out of their grooves using flat bar or chisel. It is important to be patient, as these are often placed in a wedge or nail. If the sash is still in place, pull the mortise and tenon joints free with a screwdriver or hammer, then remove each wood peg. You should be able to move the sash back and forth freely, although it may require oiling if it seems stiff.
Determine the length of sash cord/chain needed to reach the sash slot at the bottom from the pulley on the top of the jamb. Cut the cord or chain and secure it as 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 recommended to keep the original weights if you have purchased a kit that will replace the counterbalance that was previously installed. They're not costly and are easy to install if purchased them at architectural salvage stores. Based on the size of your window, two or three sash weights might be required to keep it open.
