Window Sash Repairs
Window sashes need to be checked regularly for mold, mildew, and damage. You can reduce future repair costs by catching problems early, before they get out of hand.
The sash is the interior frame that is vertically moved up or down in windows that are open. This article will show you how to make several simple sash repairs.
Weather Stripping
Wooden window sashes are a great way to add a classic look to your home. They are also durable and can last many years when they are maintained properly. However, they can become damaged or degrade in time due to exposure to the elements and wear and wear and tear. However, sash repair experts can bring your windows back to their original condition and keep them looking fantastic for longer than replacement windows.
Weather stripping is the primary aspect to consider when you are repairing sash windows. It is located on both the frame and the sash. It can cause drafts if worn or loose. To fix it, begin by determining your window's brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Take double glazing repairs Bedford off, and mark its width and height so that you can find a replacement weather stripping that matches.
Then, take the sash from the holder and place it on an even surface that allows you to see all four sides. If your sash has been double-hung, you must remove the ropes and weights that should have fallen into the pocket in the jamb lining. After you have removed the sash using the utility knife, take off the old weather stripping by hand or with a putty knife.
After the sash has been cleared, 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 could also use scrap wood.
After removing the parting stops and cutting them to the desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, then let it dry for a minimum of a day. Once the putty has fully cure, you can apply a topcoat of acrylic. This will protect the putty and give your sash a modern look.
Sash Hardware
The hardware that supports window sashes is prone to wearing out from the wear and tear of use, and the result can be a window or door that isn't able to open or close easily. It's a good idea to know that replacing and fixing this hardware is usually straightforward 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 problem. If the issue continues it's most likely that the sash balance is off. You will need to remove the window sash to reach this hardware.
Window sashes should be able to open and close with minimal effort. However, this may be difficult if the weights are worn out or the sash connecting rail isn't properly coated. This problem could be caused by many factors such as an absence of maintenance or an unmatched weight rating.
If the hinges on a window begin to sag this could cause the sash to drag, and then eventually to hit the frame in the opposite corner (Photo 1). To correct the issue make sure the sash is in the proper position within the frame's opening and remove it. If the sash is secured to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Due to hinges that are sagging, and a general deficiency in energy efficiency, windows that are old, especially those in older homes, may be difficult to open or close. Many times it is a matter of making a few minor adjustments that can allow these windows to operate smoothly and help homeowners save money on energy bills.
To complete these repairs to sash it is 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 pencil. This will allow you to position the channel in the right position after you've finished. Remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place. Soften any hardened putty with an electric heat gun set to medium and fitted with a shield for the nozzle. Take off the old sash and store it in a bag with a label.
Sash Weights
Sash weights can be replaced to improve the operation of your window sash and reduce the cost of energy. Sash weights are composed of iron or lead cylindricals that are contained inside a concealed cavity, and attached by ropes to the movable window sash. They function as counterbalances, which allows you to open and shut the window without requiring mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners.
It's difficult to retrieve an sash-weight which has fallen from the cavity, so you'll want to find one that fits properly. You will also require an additional piece of string, a length of the sash cord, as well as some sash pulleys that will tie the new sash weights to the sash cord.
Mortise and Tenon joints are used to join old wood windows. Hammers and pins can be used to take out the wood pegs that hold the parts together. Most of them have large diameters on one side and a smaller one on the other side, so it is crucial to take out the small-diameter sides first. Later sashes utilized glue instead of pins. They can be cut by using a knife and mallets.
After the sash has been removed, you can remove the sash stop and gain access to the weight pocket. Usually, this is done through a hole near the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the inner workings.
When the sash has been shut off and the access panel has been removed, you can remove the weight that was previously installed and replace it. First, weigh the sash because the weights you've got may not be the right size. Once the new weight is in place you can tie a string around it and then thread it through the pulley of the sash. Then, you can attach the string to your boxed frame. Leave a few inches protruding at the head of the string for future adjustments.
Sash Cords
In the majority of old double-hung windows, a chain or cord is affixed to the weights. This keeps the sashes in the jamb in a balanced manner. Over time these cords can break, making it difficult to raise the window. A new sash cord will give you the ability to move the sash upwards and downwards and will keep it in its position when it is opened.
The first step in replacing sash cords is to find and remove the access panels in the jambs. These are usually attached by nails or screws and require removal. It may be possible to remove them with an axe or hammer, but it is always better to lay out dust sheets prior to beginning any work.
After removing the access panel, you are able to begin to work on the sash. Make the small parting beads (also known as "tie rails") out of their grooves using the chisel or flat bar. These are often wedged in or nailed in, but they can be snipped out which is why it's worth your time. If the sash remains in place, pry out the mortise and tenon joints using a hammer and pin punch or screwdriver, then unhook the wood pegs that are on each piece. You should be able to move the sash back and forth freely, although it might require oiling if it seems stiff.
Measure the length of sash chain/sash cord required to reach the sash slot at the bottom of the pulley located at the top of the jamb. Cut the chain or cord, and then attach it as described in the step 6 above. You can use a hammer, nails, or screws. However, nails are less likely to cause damage.
If you don't have a kit that replaces the counterbalance system that was in place before, it is recommended to keep the original weights for balancing in place. It's not expensive to buy them from a salvage store and they'll be simple to install once you have the sash opened. Depending on the dimensions and shape of your window, you may need to use one or two sashweights to keep the sash open.
