Weather Stripping
Wooden window sashes can give an elegant look to your home. They are also sturdy and last for a long time if they are properly maintained. However, they can be damaged or deteriorate over time due to exposure to elements and normal wear and wear and tear. Thankfully, sash repair experts can bring your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.
The first step for sash window repairs is addressing weather stripping. It's found on both the sash and frame. It can cause drafts if it's worn out or loose. To fix it, start by finding your Window repair 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, remove the sash and mark its height and width to find new weather stripping that matches.
Then, take the sash from the holder and place it on a flat surface to allow you to reach all four sides. If your sash was double-hung, you must remove the weights using their ropes that should have fallen into the pocket inside the jamb lining. Once you've removed the sash, use a utility knife to cut away 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 has been cleared, you can replace the parting stops. They are long pieces of wood that separate the two sashes. Pam prefers to use standard 1/2-inch by 3/4-inch upvc window repair trim from the lumberyard. But, you can also use with a scrap piece of wood.
After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound 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 protect the putty, and give your sash a modern look.
Sash Hardware
The hardware that supports window sashes can wear out over time and use. This could result in the window or door that is difficult to open or close. It's a good idea to know that replacing or fixing this hardware is usually straightforward and cost-effective. If a sash becomes difficult to operate try spraying grease into the jamb channel and then open it to see if that fixes the problem. If not, the problem is most likely due to the sash balance, and you'll have to take off the sash to gain access to this hardware.
Window sashes should be able to open and close with minimal effort. However, this can be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't properly glazed. This issue can be due to many factors such as an absence of maintenance or a mismatched weight rating.
If the hinge arms 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 address this issue, first make sure the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash has been screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).
Old windows, particularly those in older homes, may be difficult to open and close due to sagging hinges and a general lack of energy efficiency. In many cases, a few simple repairs can transform these windows into smooth operation for the first time and save the homeowner cash on energy costs.
It is essential to have the tools you need before you begin. Mark the hinge channel location on the frame (Photo 1) with a pencil. This will assist you in getting the channel back into the correct position after you've finished. Then, remove the sash and remove the hardware, including the parting beads (Photo 2) and the chains or cords that secure it. Heat gun with nozzle shield and a medium setting can soften any hardened putty. Remove the old sash, and store it in an bag that is labeled.
Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or simply to keep your windows functioning and functional, replacing worn-out weights for sash will improve its operation and cut down on the energy cost. Sash weights are hefty lead or iron cylinders that are enclosed in a concealed cavity and attached to the movable window sash using rope. They provide counterbalance, allowing 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 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 require a fresh piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.
Older windows made of wood are joined using mortise and tenon joints. The wood pegs that hold the components together can be removed with pin punches and hammers. The majority of these pegs are big on one side, and smaller on the other. It is essential to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting the glue line with the help of a knife, and then tapping the mortised part loose using mallets.
Once the sash is freed, you can remove the sash stop and access the weight pocket. Usually, this is done through an opening in the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inside workings.
Once the sash is stopped and the access panel has been removed, you can take off the old weight and replace it. First, weigh the sash because the weights you have might not be the right size. 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 head of the string to allow future adjustments.
Sash Cords
In the majority of double-hung windows, a cord or chain is affixed to the weights. This supports and keeps the sashes of the jamb balanced. Over time, these chains can get damaged and make it difficult to raise the windows. A new sash cable will give you the ability to move and lower the sash, and ensure it stays in place when opened.
The first step in replacing sash cords is to find and remove the access panels in the jambs. These are usually fixed or screwed in and will need to be removed or moved. It may be possible to remove them with a hammer or chisel, however, it is 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. Use a flat bar or chisel to pry the tiny parting beads out of their grooves. They are usually wedged in or nailed in, but they can be removed which is why it's worth your time here. If the sash is in place, pry out the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, and then take out the wood pegs that are on each component. It should now be possible to move the sash back and forth freely, although it will probably need some oil if it feels stiff.
With the sash open Take a measurement of the sash chain to extend from the pulley at the top of the jamb to the sash slot at the bottom. Cut the cord/chain, and then secure it in Step 6 above. You can either use a hammer and nail or screws, but nails are less likely to cause damage.
Unless you've bought an upgrade kit to replace the old counterbalance system it is recommended to keep the original weights for balancing in place. It's cheap to purchase them from a salvage store and they'll be easy to install once you have the sash opened. Based on the size of your window, one or two sash weights might be required to keep it in an open position.
