Weather Stripping
Wooden window sashes can add an elegant appearance to your home. They are also sturdy and will last for many years when they are maintained properly. However, they may become damaged or deteriorate over time due to exposure to the elements and wear and wear and tear. Sash repair experts can restore windows to their original condition and keep them looking great longer than replacement windows.
Weather stripping is the primary issue to take care of when fixing windows with sash. It's on both the frame and sash. If it's loose or worn out, it can cause drafts, as well as other issues. To fix it, begin by finding your window 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 width and height to find new weather stripping that matches.
Next, remove the sash and set it on a table to allow access to all four sides. If your sash has been double-hung, remove the weights with their ropes that should be buried inside the jamb lining. After you have removed the sash using the utility knife, you can remove the weather stripping from the old sash by hand or with the putty blade.
Once the sash has been cleaned, you can replace the stoppers that separate the two sashes. These are long pieces wood that divide the two sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you can also use with a scrap piece of wood.
After removing the stoppers for parting and cutting them to the desired length and thickness, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using your putty tool, and let it dry at least one day. When it's completely dried, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a new look.
Sash Hardware
The hardware that holds the window sashes can wear out with time and use. This can result in windows or doors that is difficult to open or close. It's a good idea to know that replacing or repair of this hardware is typically straightforward 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 that solves the issue. If the issue continues it's likely to be due to the sash's balance. It is necessary remove the window sash to access the hardware.
Ideally, window sashes must be able to open and close with minimal effort but this is a difficult task when the weights are worn or if the sash's meeting rail isn't properly coated. This problem can be caused by a number of factors, including lack of maintenance or by an incorrect weight rating for a particular window sash.
If the hinges on the window begin to move, this could cause the sash to drag and then hit the frame in the opposite corner (Photo 1). To address this issue, first make sure the sash fits squarely in the frame's opening and then take it out of the window. If the sash was fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Old windows, particularly those in older homes, may be difficult to close and open due to hinges that are sagging and general lack of energy efficiency. In most instances, a few minor repairs can turn these windows into smooth operation again and save the homeowner money on energy bills.
It is essential to have the tools you require before you begin. Mark the hinge channel's location on the frame (Photo 1) with pencil. This will allow you to place the channel in the proper place when you are finished. Take the sash off and take out all the hardware including the parting beads cords, chains, and cords that keep the sash in place. The nozzle shield of the heat gun and a medium setting can soften any putty that has been hardened. Remove the old sash, and store it in an labelled bag.
Sash Weights
Sash weights can be changed to improve the operation of your window sash and decrease the energy cost. Sash weights are hefty lead or iron cylinders enclosed in a concealed cavity and linked to the moveable the sash with a rope. They are counterbalancers, allowing the window to be closed and opened without the need for mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and then turned into scrap when they break; therefore you might need to search for replacements.
A weight from a sash that fell out of the cavity is difficult to recover and you'll need to find a replacement that fits correctly. You will also require an additional piece of string, a length sash cord, and a few sash pulleys to tie the new sash weights the sash cord.
Older windows made of wood 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 these pegs are large on one side and smaller on the other. It is important to first remove the smaller diameter sides. Later sashes made use of glue instead of pins. They can be cut with a knife and mallet.
Once the sash has been removed, you can take off the sash stops and gain access to the weight pockets. This is typically done by drilling an opening at the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the inside workings.
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 new. Be sure to weigh the sash first because the weights you have may not be the correct size. Once the new weight is installed you can tie a string around it and thread it through the pulley for the sash. Then, attach the string to your boxed frame. Leave a few inches at the top of the string to allow future adjustments.
window repairs of double-hung windows with a history include a chain or cord attached to the weights which supports and keeps the sashes level in the jamb. Over time, these cords could break, making it difficult to raise the window. 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 locate and remove the access panels within the jambs. These are usually nailed or screwed in and will need to be removed or relocated. It may be possible to remove them using an axe or hammer, but it is always best to lay out dust sheets before beginning any work.
After you have removed 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. They are typically wedged into or nailed in, but they can be removed which is why it's worth your time here. If the sash remains in place, pry the mortise-and tenon joints using a hammer or screwdriver and then take out each wood peg. You should be able to move the sash back and forth freely, though it will probably need some lubrication if it feels stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord or chain and secure it as in the previous step. You can use a hammer and screws or nails, however nails are less likely to cause damage.
If you don't have an item that replaces the old counterbalance system it's 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 easy to install once you've got the sash opened. Based on the dimensions and shape of your window, you may require one or two sashweights to keep it open.
