Weather Stripping
Wooden window sashes can add an elegant look to your home. They are also durable and can last many years if they are properly maintained. However, they can be damaged or degrade as time passes due to exposure to elements and normal wear and tear. Sash repair specialists can restore windows to their original condition and maintain their appearance longer than replacement windows.
The first step to repair sash window damage is to fix weather stripping. It's found on both the sash and frame. If it's damaged or worn out, it can lead to drafts and other problems. To fix it, start by determining your window's brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its height and width, so you can find new weather stripping that matches.
Then, remove the sash and place it on a surface so that you can reach all four sides. If your sash has been double-hung, take out the ropes and weights that should have fallen into the pocket within the jamb lining. Once you've taken the sash off using a utility knife, you can use it to cut off the old weather stripping at the corners. Then, remove it by hand or using a putty blade.
After the sash has been cleared, you can replace the stoppers that separate the two sashes. These are long pieces that divide the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. But, you can substitute with a scrap piece of wood.
After removing the stoppers for parting and trimming them to your desired length, apply a thin layer of glazing compound on the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for a minimum of 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 an updated appearance.
Sash Hardware
The hardware that supports window sashes is susceptible to wear and tear from time and usage and the result could be a window or door that isn't able to open or close easily. The good news is that fixing and replacing this hardware is generally very simple and cost-effective. If you are having trouble opening a sash, spray some lubricant into the jamb channel. Then, slide the sash up and open to see if that fixes the problem. If the problem persists it's likely to be due to the sash's balance. You'll need to take off the window sash to get access to this part of the hardware.
The ideal situation is for window sashes to be able to open and close without effort, but this is difficult if the weights become worn or if the sash that joins rail isn't properly glazed. This issue could be caused by a number of reasons, such as the lack of maintenance or an incorrect weight rating for the particular sash.
If the hinge arms of a window begin to sag, this can cause the sash to drag and eventually hit the frame in the corner directly opposite the hinge arm (Photo 1). To resolve upvc windows repair , first ensure that the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Due to sagging hinges, and a general lack of energy efficiency, windows that are old particularly those in older homes, may be difficult to open and close. Sometimes it is a matter of making a few minor adjustments that can help these windows function smoothly again and help homeowners save money on their energy bills.
It is essential to have the tools you require before you start. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will assist you in getting the channel back in place correctly when you're finished. Remove the sash, and remove all the hardware, including the beads for parting, cords, and chains that help to hold the sash. A hot gun with nozzle shield and medium setting will soften any hardened glue. Remove the old sash, and keep it in a labeled bag.
Sash Weights
Sash weights can be replaced to enhance the efficiency of your window sash, and also reduce the energy cost. Sash weights consist of heavy lead or iron cylinders that are encased inside a concealed cavity, and are connected via ropes to the moveable window sash. They are counterbalancers that allows the window to be shut and opened without using mechanical or electrical devices. When they fail, sashweights are usually ignored or disabled by homeowners.
It's difficult to retrieve the sash-weight that fell from the cavity, so you'll need to find one that is suitable for the. You will also require an additional piece of string, a length of sash cord, and a few sash pulleys to connect the new sash weights to the sash cord.
Older wood windows are joined using mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs holding the parts together. The majority of them are large on one side, but smaller on the other. It is essential to first remove the smaller diameter sides. Sashes made later in the century used glue instead of pegs. They can be separated by cutting through the glue line with an instrument, and then tapping the mortised area loose using mallets.
After the sash is released, you can remove stops on the sash and get access to the weight pockets. This is usually done via an opening in the bottom of each jamb. This hole is then covered by an access panel made of wood which can be removed to allow you to view the inside of the frame.
After the sash has been stopped and the access panel removed, you will be able to remove the old sash weight and replace it with the new. Be sure to weigh the sash prior to you do this, as the weights that were previously used may be different in size from what is needed. After the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches at the top of the string to allow for future adjustments.
Sash Cords
In the majority of old double-hung windows the chain or cord is attached to the weights. This helps keep the sashes of the jamb level. Over time, these cords could break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash upwards and downwards and keep it in place when opened.
To replace sash cords the first step is to remove the access panels from the jambs. These are usually nailed or screwed in and will need to be removed or relocated. You may be able to use a hammer or chisel to prise them off but it's best to lay down dust sheets before beginning any work.
After the access panel has been removed, you can begin working on the sash. Utilize a flat bar or chisel, to pry the small parting beads out of their grooves. It is important to take your time because they are usually wedged or nailed in place. If the sash remains in place, remove the mortise and tenon joints using a hammer and pin punch or screwdriver, and then take out the wood pegs attached to each piece. The sash should be able move freely, however it may require some lubrication in order to feel less stiff.
Measure the length of sash chain/sash cord required to reach the sash slot at the bottom, and the pulley on the top of the jamb. Cut the cord or chain, and then fix it using the step 6 above. You can use a hammer and screws or nails, however nails are less likely to cause damage.
Unless you've bought an item that replaces the old counterbalance system, it is recommended to keep the original balancing weights in place. They're not expensive and are easy to install if you buy them from salvage shops for architectural use. Based on the size and shape of your window, you may need to use one or two sashweights in order to keep it open.
