Sash Window Repair
Sash windows can add a stylish aesthetic to a home. However, they can also be problematic and drafty because of wear and age.
Sash window repairs are a great method of improving functionality and maintaining the original appearance.
The first step in repairing sash windows is to remove the "pocket covers". These are pieces of wood, low down on the frame that give access to the weights.
Sashes damaged by abrasions
If your windows' sash are damaged or leaky, you'll need to do more than patch up the surface. You'll save money by doing a more thorough repair, particularly if your home is older and has low insulation. Here are some common sash window problems and how to fix them:
Sticking Issues
If the sash isn't fitted tightly within the frame, it's difficult to open or close the window. This can result in rattling noises and allow drafts to enter your home.
To fix this issue solution, use a knife to score the paint line on the inner side of the sash and remove it. Be careful not to damage the wood. Then, you'll need to apply a sash lubricant that will help it move along smoothly.
Broken Sash Cords
In some cases, old double-hung sashes are made of metal or cotton cords 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 and keep it up. Follow these steps to fix it:
Pull the sash to the right and take it off the frame. Cut the cord on the bottom of the sash. Remove any nails sticking out of the end. Take the nail off using needle-nose pliers, then reinsert it into the side channel. Insert the knot of the cord into the hole and secure it with a nail set.
Install the sash again and add the staff beads. Make sure you leave enough slack in the cords for the proper operation. Then, you can reinstall the counterweights and balances. To minimize draughts small amount of decorators caulk could be placed between the staff bead and the box.
After the frame and sash are completely repaired, you can bed them in glazing putty. Glazing putty can be made with linseed and chalk. Mix in enough of the chalk to allow it to work and not stick to your hands. Let the putty dry completely before installing the sash again and painting the frame.
Broken sash cords
To support and balance the sashes of old
wooden double glazed sash windows-hung windows (two sashes), cotton cords or chains are tacked to counterweights. Over time, the cords could break, which stops the sashes from opening and closing, making it difficult to lower or raise the window. Repairing the sash cords is a simple home fix that can solve these problems in less than an hour.
Begin by removing your staff bead that divides the upper and lower sashes. A nail is typically driven through the knot and then into the side of the sash casing to keep the bead, but you should be in a position to remove it with needle-nose pliers. Remove any rusty nail from the stop beads, and then clean the caulk, old cord residue, and paint around the groove of the sash.
To open the window, pull on one of the cords that run through the sash to raise it up. Once you've gotten as far as you can mark the cord with a pencil and cut it out using an utility knife. After you've finished, make sure that the new cord is aligned with the groove of the sash. Also, tie it to the sash with a knot.
If the sash still isn't moving, cut the cords using your side cutters. When the sash is completely free you'll need to take off the access panel inside the sash channel in order to expose the sash weight pockets, the counterweights, and the pulley system. If the window has been painted, you will need to score the seams using either a hammer or chisel, to remove the panel without damaging it.
After you've removed the access panel, you'll be able to see the two sash weights made of cast iron in each pocket. Remove the weights on the back and front and then tie the sash cords onto the weights with self-tightening knot. After you have tied the new cords, you can reattach the sashweights and reset the system to work correctly.
Drafts
Sash windows add a bit of the past to older homes but they also present problems with maintenance. They are often difficult or impossible to open and close, rattling in the wind, and letting drafts in. These issues could be caused by swollen or painted wood or sash cords that have rotted. There are a number of simple and cost-effective ways to correct these issues and keep your sash window operating properly.
The first step in repairing an old sash window is disassembling it. Take off the sash and frame, and ensure that all components are in good condition. Then, sand down the wood to improve 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, use a knife to cut through any paint layers to release it. The addition of a new set tilt pins can also help improve the window's operation.
A sash window operates by compensating the weight of the glass with the help of weights that are passed through a pulley system. The weights, typically constructed of cast iron, can be accessed through an access panel or pocket located within the lining of the box. A dividing strip is put within the window frame to stop the weights from colliding.
Accessing these weights can be tricky, as the upper sash is sealed and can be secured by nailing it in place. If you're patient and careful you can pull the sash out with a pair of bar clamps spread apart. You may need to tap and jiggle to release it, but once it's out, inspect the sash and replace it if necessary with new rope.
You can also replace the balance of the sash to make it easier to open and close the window. Replacing the balance of a double-hung window is much easier than it sounds and you can do it yourself with the proper tools and replacement kit.
Rotten sill
Even the best-maintained windows can eventually exhibit signs of rot. If the rot only affects the sill of the window, it may be possible to fix it. If the rot has spread through the frame and even into the interior, and damaged structural components it could be time to replace the window.
It is crucial to replace a rotten window sill before it causes more damage to the window. The first step is to take off the sill plate that was previously installed and studs. If the studs are load-bearing, you may need to build temporary supports. After taking the old sill off and washing off any remaining paint from the sill plate. Once the sill is clean, replace it with a brand new board and nail it to the studs.
A stained sill is not only unsightly but it could also lead to expensive repairs in the future. It could, for instance, cause the sash, that is hard to see, to shift. This can result in cracks, bowed or damaged glass pane. A rotten sill can let water in the wall and cause mold.
It's not as difficult as it appears to repair a sill that is rotten. It is vital to maintain the window to avoid rot, therefore you should clean regularly the windows' tracks and sashes to keep them free from dirt and other debris. You should also apply a protective seal on the window frames to protect them from moisture. Lastly, you should use a dehumidifier in order to control the humidity levels within your home, which will stop

Sticking sashes are a common problem with
sash secondary glazing windows. To resolve them you can apply a small amount of wax or silicone spray to the window tracks to enable them to slide easily. If the windows are stuck due to the buildup of paint, you can use a utility knife to cut through the layers of paint to release the sashes.
Reinstalling the bead that is parting is another way to get rid of a stuck sash. If the sash is still stuck, you could consider draught-proofing it. This involves putting an insulating strip of rubber in the spaces between the frame and sash, which reduces air flow and improves the acoustic quality of the window.
