10 Window Sash Repairs That Are Unexpected
Window Sash Repairs
Window sashes must be checked regularly for mold, mildew, and damage. By catching problems before they become serious you will save money on future repairs.
The sash is an internal frame that moves upwards and downwards in windows that open. This article will demonstrate how to carry out a few simple sash repair.
Weather Stripping
Wood window sashes give an elegant look to your home. When properly maintained, they can last for many years. However, they can get damaged or deteriorated over time due to exposure or normal wear and tear. Fortunately, sash repair specialists can bring your windows back to their original condition and keep them looking fantastic for longer than replacement windows.
Weather stripping is the primary issue to take care of when fixing windows that have sash. It's on both the frame and the sash. If it's worn or loose, out, it could cause drafts and other problems. To fix it, begin by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off and mark its size and width so that you can find a new weather stripping that is compatible with the original.
Then, take the sash from its holder and place it on an even surface that allows you to access all four sides. If your sash is double-hung, you'll need to remove the weights and their accompanying ropes which should have slipped into the pocket of the jamb liner. Once you've removed the sash, use a utility knife to remove the weather stripping that was formerly in place at the corners. Then, take it off by hand or using a putty blade.
Once the sash is clear, you can replace the parting stops. These are long pieces wood that divide the two sashes. Pam likes to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard, however you can also replace them with a piece of scrap wood.
After removing the stopper and trimming it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty tool, and allow it to dry for at least a day. Once the putty has fully cure and dried, you can apply a topcoat of acrylic. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes susceptible to wear and tear from the wear and tear of use, and the result can be a door or window that isn't able to open or close easily. It's good to know that replacing and repairing this hardware is often simple and inexpensive. If you're having difficulty opening a sash spray some grease into the jamb channel. Then slide the sash out to see if it resolves the problem. If the problem persists it's likely that the sash balance is off. You will need to remove the window sash in order to reach this hardware.
Window sashes need to open and close with little effort. However, this can be difficult if weights are worn out or the sash-to-rail connecting rail isn't properly covered with. This can be due to various reasons, including the lack of maintenance or a mismatched weight rating.
If the hinge arms of a window begin to sag, this can cause the sash to slide and eventually strike the frame in the corner directly opposite the hinge arm (Photo 1). To resolve this issue, first make sure the sash fits squarely in the opening of the frame and then take it out of the window. If the sash was screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Due to hinges that are sagging, and a general lack of energy efficiency, old windows particularly those in older homes, may be difficult to open or close. In many cases it is a matter of making a few minor adjustments that can help these windows function smoothly once more and save homeowners money on their energy bills.
It is crucial 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 on position correctly after you've completed. Remove the sash and then remove all hardware, including the beads for parting, cords, and chains that keep the sash in place. The nozzle shield of the heat gun and a medium setting can soften any hardened putty. Take off the old sash and put it in a bag that is labeled.
Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or just to keep the windows functional by replacing worn out sash weights will improve sash operation and reduce the energy cost. Sash weights are heavy, lead or iron cylinders enclosed in a hidden cavity and linked to the moveable the sash with a rope. These weights function as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights are usually left unnoticed or disabled by homeowners.
A weight in a sash that has fallen out of the cavity is difficult to get back, so you will want to locate a new one that fits correctly. You will also require a fresh piece of string, a length sashcord and some sashpulleys to tie the weights you are replacing to the cord.
Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs holding the parts together can be removed with a pin punch and hammer. The majority of them have a large diameter on one side and a smaller diameter on the other, which is why it is important to remove the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be cut with a knife and a mallet.
After the sash has been removed then you can take out the sash stop and gain access to the weight pocket. Usually, window repair is done through an opening at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the inside workings.
When the sash has been shut off and the access panel has been removed, you can remove the weight you used and replace it. Be sure to weigh the sash prior to you do this, since the weights that were previously used may be a different size than what you require. Once the new weight is installed, tie a string to it and thread it through the pulley of the sash. Then, you can attach the string to the boxed frame. Leave a few inches of space at the end of the string to allow future adjustments.
Sash Cords
Most old double-hung windows have a cord or chain connected to the weights that helps keep the sashes in balance in the jamb. Over time these cords can break, making it impossible 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 place 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 screwed or nailed into and must be removed. You may be able to employ a hammer and chisel to prise them off however, it is always best to lay down dust sheets before beginning any work.
After the access panel has been removed, you can start working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with the chisel or flat bar. These are often wedged in or nailed, but they can be snipped out and it's worth your time. If the sash is still in place, pull the mortise-and-tenon joints out using a hammer or screwdriver and then take out each wood peg. You should now be able to move the sash around without difficulty, though it will probably need some oiling if it seems stiff.
Measure the length of sash cord/chain required to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the cord/chain and then secure it as in the previous step. You can use either a hammer, nails, or screws. However, nails are less likely to cause damage.
If you haven't purchased an item that replaces the old counterbalance system, it is recommended to keep the original balancing weights in place. It's not too expensive to purchase them from architectural salvage stores and they'll be simple to install once you've got the sash open. Depending on the dimensions and shape of your window, you might need to install one or two sashweights in order to keep it open.
