Sash Window Repair
Sash windows add a touch of elegance to any home. They can become drafty and difficult to repair as they get older. Repairs to windows with sash are a great way of making them more functional and preserving the original appearance.
The first step in sash window repair is to take off the "pocket covers". secondary glazing sash window are bits of wood that are placed low on the frame that give access to the weights.
Damaged sashes
If your sash windows have been damaged or leaky, you'll need to do more than repair the surface. Performing a more comprehensive repair job will save you money in the long run, particularly when you live in an older home with poor insulation. Here are some common problems that sash windows face and the way to fix them:
Stuck Issues
If the sash isn't fitted snugly within the frame, it may be difficult to open or close the window. This could result in rattling sounds and let drafts in your home.
To fix this issue, use a utility knife to cut the paint line on the inner side of the sash and take it off. Be careful not damage the wood. You'll then need to apply a sash oil, which will allow it to move smoothly.
Broken Sash Cords
In some cases, old double-hung sashes are made of cords made of metal or cotton to support the weights that lift and lower the sashes. As time passes, the cords could break and make it difficult to lift the sash up or keep it up. Follow these steps to fix the problem:
Remove the sash from the frame and pull it to the right until it's completely open. Cut the cord on the bottom of the sash and remove any nails sticking out from the end. Take the nail off using needle-nose pliers, and then insert it back into the side channel. The knot of the cord should be tucked into the hole, and secure it using a nail set.
Install the staff beads and install the sash. Make sure you leave enough slack in the cords for optimal operation. Finally, reinstall the counterweights and balances. To minimize draughts small amount of decorators caulk may be placed between the bead of the staff and the box.
When the frame and sash are repaired completely, cover them in glazing putty. Glazing putty is typically made from linseed oil as well as chalk. Mix in enough chalk to make the putty workable and not stick to your fingers. Allow the putty to dry completely before reinstalling the sash, or painting the frame.
Broken sash cords
To balance and support the sashes in old double-hung windows (two sashes) cotton cords or chains are affixed to counterweights. As time passes, the cords may break, preventing the sashes from opening or closing and makes it difficult to lower or raise the window. The cords of the sash can be replaced in less than hour.
Start by removing the staff bead, which separates the lower and upper sashes. You can remove the bead by using needle-nose pliers. A nail is inserted through the knot into the sash's casing to secure it. Remove any nail that is rusty from the stop beads and then clean the caulk as well as the old cord residue and paint around the groove of the sash.
To open the window pull one of the cords running through the sash. When you've pulled it as far as it will go make a mark on the cord using a pencil and cut it to length using a utility knife. When you're done, be sure that the new cord is in alignment with the groove of the sash. Also, tie it to the sash by knotting the knot.
If the sash isn't moving you can cut the cords with your side cutters. Once the sash is removed, you'll need to remove the access panels inside the sash channels, exposing the counterweights and pulley system. If the window is painted, you may need to score the seams with the hammer and chisel in order to remove the access panel without damaging the paint.
After removing the access panel, there are two cast-iron sashweights in each pocket. Take the one on the back and the other on the front, then tie each sash cord to a weight with a self-tightening knot. After you tie the new cords, you'll need to reattach the sash weights and then reset the pulley system so that it works correctly.
Drafts
Sash windows are a fantastic option to add a touch of history to older homes. However they can be difficult to maintain. They can be difficult or even impossible to open and close with a smooth, quiet operation. They can also be rattled by winds, and letting drafts through. These problems could be caused by swollen or painted wood, or rotted sash cords. Fortunately, there are many easy and cost-effective ways to address these issues and keep your sash windows functioning effectively.
Disassembling an old sash is the first step in fixing it. Take off the sash and frame, and ensure that all components are in good shape. Then, sand down the wood to enhance its appearance and prevent draughts. A small amount of silicone or wax spray can help the sash slide more easily. If the sash remains stuck using a utility knife, you can use it to cut off any paint layers. A new set of tilt pins can enhance the window's performance.
A sash window functions by counterbalancing the weight of the glass with the help of weights passed over the pulley system. The weights are typically cast iron and can be accessed from an access panel or pocket cover in the inner box lining of the window frame. To prevent the weights from colliding, the dividing strip is suspended within the frame to ensure that they don't collide.
Accessing these weights can be difficult, since the upper sash is painted shut and is nailed into the position. If you are patient and careful you can take the sash off using a pair bar clamps spread apart. It might take a bit of jiggling and tapping to get it out but once you've got removed it, make sure to check the sash cord and replace it with new rope (not cotton) in the event that it is required.
While you're at it you could also replace the sash balance to make it easier to open and close. It's much easier than you think to replace the double-hung balance on a window. You can do it yourself if have the right tools and replacement kit.
Rotten sill
In time, the old timbers will become damaged and even the best-maintained windows made of sash will begin to begin to show signs of decay. If the rot only affects the sill of the window, it could be possible to fix it. If it has spread through the frame and into the interior of the house and has damaged structural members it's likely time for a replacement.
It is crucial to replace a damaged window sill before it causes damage to the window. The first step is removing the sill plates and studs. You may have to install temporary support if the studs are weight-bearing. After you have removed the sill, take off any paint that remains on the sill plate. After cleaning the sill and replacing it with the new board and then nail it into the studs.
A rotten sill can be unsightly and lead to future expensive repairs. For instance, it could cause the sash's to shift and can be difficult to notice and can result in a cracked or bowed glass pane. Additionally, a rotten sill can allow water to be able to enter the wall, which can cause mold and other problems.
It's not as difficult as you think to replace a rotten sill. It is crucial to maintain your window to avoid rot, therefore you should regularly clean the windows' tracks and sashes to keep them clear of dirt and debris. Also, you should apply a protective seal to the frames of your windows to shield them from moisture. Additionally, you should utilize a dehumidifier to regulate the moisture levels within your home, which can prevent wooden sashes from expanding or sticking.
Sash windows are usually plagued by sashes that are stuck. This issue can be fixed by applying a small amount of wax or silicone to the window tracks. This will help them slide along more easily. If the windows are stuck due to paint buildup, you can employ a utility knife to cut through the layers of paint and release the sashes.
Reinstalling the parting beads is another method to get rid of a stuck sash. If the sash is still stuck, you can try to draught proof it. This is done by placing an insulating strip of rubber in the spaces between the sash and frame which decreases air flow and improves the acoustic quality of your window.
