Sash Window Repair
Sash windows offer an elegant design to homes. They can become drafty and difficult to repair as they age. Repairing sash windows is a great way to improve functionality while maintaining the original appeal of your windows.
The first step in repairing windows with sash is to remove "pocket covers". These are tiny pieces of wood that sit at the bottom of the frame and allow access to the weights.
Sashes damaged by abrasions
If your sash windows are damaged or leaky, you'll need to do more than just patch up the surface. A more thorough repair will save you money in the long run, especially when you live in an older home with poor insulation. Here are some common problems with sash windows and the best way to fix it:
Sticking Issues
It can be difficult to close or open the window in the event that the sash does not fit tightly into the frame. This could result in rattling sounds and allow drafts into your home.
To solve this issue, use an utility knife to cut and pry off the paint line from the inside side of your sash. Be careful not to damage the wood. Then, you'll need to apply a sash grease that will make it move more smoothly.
Broken Sash Cords
In some instances, older double-hung sashes are made of cords made of metal or cotton to support the weights used to lift and lower the sashes. Over time, these cords may break and make it difficult to lift the sash and keep it up. To fix this issue, follow these steps:
Remove the sash from the frame and pull it to the right until it's completely open. Cut the cord at the bottom of the sash. Remove any nails that are sticking out from the end. Take the nail off using needle-nose pliers and then reinsert it into the side channel. Incorporate the cord knot into the hole, and secure it using a nail set.
Install the beads for staff and install the sash. Make sure you leave enough for the cords to ensure that they are in good working order. Reinstall the counterweights and balances. Decorators caulk is an excellent way to prevent draughts. Apply small amounts of caulk between the bead boxes for staff.
When the frame and sash are completely repaired, you can bed them in glazing putty. Glazing putty can be made by mixing chalk and linseed. Mix in enough of the chalk to allow it to work and not to stick to your hands. Let new sash windows repairmywindowsanddoors before reinstalling the sash, or painting the frame.
Broken sash cords
To balance and support the sashes in old double-hung windows (two sashes), chains or cotton cords are affixed to counterweights. Over time, the cords could break, which stops the sashes from opening or closing and makes it difficult to lower or raise the window. The cords for sashes can be replaced in less than an hour.
Begin by removing the staff bead that divides the lower and upper sashes. A nail is usually driven through the knot, and then into the sash's casing to secure the bead, however, you should be in a position to remove it by using needle-nose pliers. Remove any rusty nails from the stop beads and clean off any paint, caulk and old cord traces around the groove in the sash.
To open the window, pull on one of the cords that runs through the sash to lift it up. When you've made it the maximum distance you can mark the cord with a pencil and cut it using an utility knife. When you're done, make sure the new cord matches with the groove of the sash and that it's connected to the frame by knotting it.
If the sash still isn't moving, you can cut the cords with your side cutters. Once the sash is liberated, you'll have to remove the access panels within the sash channels to expose the pulley system and counterweights. If the window has been painted, you'll need to score the seams using a hammer or chisel in order to remove the panel without damaging it.
After you have removed the access panel you will find two sashweights made of cast iron in each pocket. Take the one on the back and the one on the front, and then tie each sash cord to a weight using a self-tightening knot. After you tie the new cords, you'll need to reconnect the sash weights and reset the pulley system to ensure that it is working correctly.
Drafts
Sash windows are an excellent option to add a touch of history to older homes. However they can be a challenge to maintain. They can be difficult or impossible to close and open with a smooth, quiet operation. They can also be rattled by breeze, and allowing drafts in. These problems are often caused by swollen wood or paint buildup, or sash cords that have become rotted. Fortunately, there are many inexpensive and cost-effective methods to repair the problem and keep your windows operating correctly.
The first step in repairing an old sash window is to disassemble it. Take off the sash and frame, and ensure that all parts are in good condition. Next, sand down the wood to improve its appearance and stop drafts. A small amount silicone spray or wax can make the sash slide more easily. If the sash is still stuck using a utility knife, you can use it to cut off any paint layers. A new set of tilt pins can also improve the window's functionality.
A sash window works by compensating the weight of the glass using weights that are pushed through the pulley system. These weights, which are typically made of cast iron can be accessed through an access panel or pocket on the inner box lining. A dividing strip is placed inside the window frame to prevent the weights from colliding.
It isn't easy to get these weights out, since the sash's upper part can be painted shut and put in place. If you are cautious and patient, you can remove the sash using a pair bar clamps that are spread apart. It might take a bit of tapping and jiggling to get it free, but once you have removed it, make sure to examine the sash cord and replace it with new rope (not cotton) If you need to.
While you're at it you could also change the sash balance to make the window easier to open and close. Replacing the balance of a double-hung window is much simpler than it is and you can do it yourself using the appropriate tools and a replacement kit.
Rotten sill
Even the best-maintained windows can eventually begin to show signs of rot. If the rot is only affecting the sill of the window, it may be possible to repair it. If, however, it has progressed through the frame into the interior of the home and has damaged structural members, it is probably the right time to replace it.
If you've got rotten sill, it's important to replace it before it causes further damage to your window. The first step is to remove the old sill plates and studs. If the studs are load-bearing you may have to build temporary supports. After taking off the sill, clean any paint that remains on the sill plate. After cleaning the sill then replace it with the new board and then nail it into the studs.
A sill that is rotten is not just ugly, it can cause costly repairs in the future. For instance, it could cause the sash's to shift and can be difficult to notice and can lead to a cracked or bowed glass pane. Additionally, a rotten sill can allow water to get into the wall which could cause mold and other problems.
It's not as difficult as you think to fix a damaged sill. It is crucial to keep the window well-maintained to avoid rot. Therefore, you must regularly clean the windows' tracks and sashes to keep them free from dirt and other debris. Apply a sealant to the frames of your windows to keep them dry. You can also apply humidifiers to manage the moisture in your home. This will prevent wooden sashes from forming or swelling.
Sash windows are often afflicted by stuck sashes. This issue can be fixed by applying a small amount silicone or wax to the tracks of your windows. This will allow them to slide along more easily. If the sashes are stuck due to the buildup of paint, you can use a utility knife to slice through the paint layers and free the sashes.
Another way to solve stuck sash issues is to reinstall the parting bead. If the sash remains stuck, you can consider draught-proofing it. This involves putting a strip of rubber between the frame of the sash and the sash. This will reduce airflow and improves the acoustic properties.
