Weather Stripping
Wood window sashes give the classic look to your home. When properly maintained, can last for a long time. However, they can be damaged or degraded over time due to exposure to the elements and wear and tear. Fortunately, sash repair specialists can bring your windows back to their original condition and keep them looking fantastic for much longer than newer replacement windows.
The first step in sash window repairs is addressing weather stripping, which can be found on both the sash and frame. If it's worn or loose, out, it can lead to drafts and other problems. To fix it, begin by determining your upvc window repair'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 height and width so that you can locate new weather stripping that matches.
Then, remove the sash and place it on a table so that you can reach all four sides. If your sash has a double-hung, you'll have to remove the weights as well as their accompanying ropes that should have fallen into the pocket of the jamb liner. Once you've removed the sash and the weights, use a utility knife to remove the old weather stripping at the corners, and then take it off by hand or with a putty knife.
After the sash has been cleaned, you can replace the stoppers that separate the two sashes. They are long pieces of wood that divide the two sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. But, you can also use a scrap piece of wood.
After removing the parting stop and cutting it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife and let it dry for at least a day. When it's completely dried then apply a top coat of acrylic latex paint. This will help protect the putty, and give your sash a modern look.
Sash Hardware
The hardware that supports window sashes is prone to wearing out from time and usage, and the result can be a door or window that can't be opened or closed easily. The good thing is that fixing and replacing this hardware is typically quite simple and inexpensive. If a sash isn't easy to operate you can try spraying some oil into the jamb channel, and then slide it open to see if it fixes the problem. If not, the problem is likely to be with the balance of the sash and you'll have to take off the sash in order to access this hardware.
Ideally, window sashes should swing open and closed with minimal effort however, this can be a difficult task when the weights wear out or if the sash that joins rail isn't properly glazed. This can be due to various reasons such as the lack of maintenance or a mismatched weight rating.
If the hinges on windows begin to slide, this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To correct the issue, make sure that the sash is centered in the frame opening, and then take it off. If the sash has been fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Windows that are old, especially in older houses, can be difficult to open and close because of sagging hinges and a general inefficiency. In most cases, a few simple repairs can transform these windows into smooth operation and save homeowners money on energy bills.
In order to make these sash repairs, it's important to have all of the tools needed before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will help you to position the channel in the correct place when you are finished. Then, remove the sash, and then remove the hardware including the parting beads (Photo 2) and the cords or chains which hold it in place. A hot gun with nozzle shield and medium setting will soften any hardened putty. Remove the old sash and store it in a bag with a label.
Sash Weights
Sash weights can be changed to enhance the efficiency of your window sash, and also reduce energy costs. Sash weights are made of heavy lead or iron cylinders that are enclosed inside a concealed cavity, and connected by a rope to the movable window sash. These weights act as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they fail. Consequently you may have to find replacements.
It is difficult to recover a sash-weight that has fallen from the cavity, so you'll need to find one that fits correctly. You will also need a new piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights to the sash cord.
Mortise and Tenon joints can be used to join old wood windows. Hammers and pins can be used to take out the wood pegs that hold the parts together. The majority of them have an enormous diameter on one side and a smaller diameter on the other side, so it is important to remove the small-diameter sides first. Sashes made later in the century utilized glue instead of pegs. They can be separated by cutting the glue line with a knife, then tapping the mortised area loose with a mallet.
After the sash is removed, you can remove the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inside workings.
After the sash has been stopped and the access panel removed, you will be able to remove the weight of the old sash and replace it with new. Be sure to weigh the sash first to ensure that the weights you have might not be the right size. After the new weight is installed you can tie a string around it and then thread it through the sash pulley. Then nail the string to the frame, leaving a few inches of string hanging from the head for future adjustment.
Sash Cords
In the majority of old double-hung windows, a chain or cord is attached to the weights. This helps keep the sashes of the jamb balanced. Over time, these cords could break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and hold it in place when it is opened.
The first step to replace cords for sash is to locate and remove the access panels within the jambs. They are usually fixed or screwed in and must be removed or moved. It is possible to remove them using a hammer or chisel, but it is always best to lay out dust sheets prior to starting any work.
After you have removed the access panel, you can begin to work on the sash. Make the small parting beads (also known as "tie rails") out of their grooves using flat bar or chisel. It's important to take your time because they are usually wedged or nailed in place. If the sash is still in place, pry the mortise-and tenon joints using a hammer or screwdriver and then take out each wood peg. The sash should move around freely now, however it may require some lubrication to feel less stiff.
Determine the length of sash chain/sash cord required to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the chain or cord and fix it as described in the previous step. You can use either a hammer, nails or screws. However, nails are less likely to cause damage.
It's best to leave the original weights if you have purchased a kit that will replace the counterbalance that was previously installed. They're not expensive and easy to install if you buy them from architectural salvage stores. Based on the size of your window repair one or two sashweights may be needed to keep it in an open position.
