Sash Window Repair
Sash windows add a touch elegance to any home. However, they can also be drafty and uncomfortable due to wear and age. Repairing sash windows is a great option to improve functionality while maintaining the original beauty of your windows.
The first step in repairing windows that have sash windows is to take off "pocket covers". These are small pieces of wood that sit at the bottom of the frame and permit access to the weights.
Sashes damaged by abrasions
If your sash window is damaged or leaks it is necessary to do more than just patch the surface. Performing a more comprehensive repair will save you money in the long run, particularly if you have a older house that has poor insulation. Here are some typical problems with sash windows and how to repair them:
Sticking Issues
If the sash isn't fitted well within the frame it will be difficult to open or close the window. This can cause rattling sounds and let drafts in your home.
To solve this issue, use an utility knife to cut and cut off the paint line on the interior side of your sash. Be careful not to harm the wood. After that, you'll need apply a sash oil that will help it move more easily.
Broken Sash Cords
Some old double-hung sashes are made of metal or cotton supporting the weights used to lift and lower the sashes. Over time, the cords can break, rendering it difficult to raise or keep the sash in place. To fix this issue, follow these steps:
Remove the frame from the sash and pull it to the right until it is completely open. Pull the cord from the bottom of the sash, cut it and take out any nails that are protruding from the end. With needle-nosed pliers, take out the nail and then insert it into the side channel. The knot should be tucked into the cord into the hole and secure it with the nail set.
Install new sash windows for staff and install the sash. Be sure to leave enough slack in the cords to ensure the proper operation. Finally, reinstall the counterweights and balances. To lessen the chance of draughts, a small amount of decorators caulk could be placed between the bead of the staff and the box.
Glazing putty can be used to repair the sash once it has been repaired. Glazing putty is made from linseed oil as well as chalk. Mix with enough chalk to make the putty usable and not stick to your fingers. Let the putty completely dry before applying the sash back and painting the frame.
Broken sash cords
Old double-hung (two sashes) windows use chains made of metal or cotton attached to the counterweights to help keep the sashes level within the window jamb. As time passes, the chains may break, preventing the sashes from opening and closing, making it difficult to lower or raise the window. The sash cords can be replaced in less than hours.
Begin by removing your staff bead, which separates the upper and lower sashes. A nail is usually driven through the knot, and then into the sash's casing to hold the bead in place, however, you should be capable of removing it by using needle-nose pliers. Remove any rusty nails from the stop beads and clean off any paint, caulk and old cord residue around the sash groove.
To open the window, pull one of the cords that runs through the sash to raise it up. When you've pulled the cord to the maximum extent it can go, mark the cord with pencil, and then cut it to length using an utility knife. After you've finished, make sure the new cord lines up with the groove of the sash, and is connected to the frame by knotting it.
If the sash isn't moving, cut the cords using side cutters. After the sash is removed, you'll have to take off the access panels in the sash channels, exposing the pulley system and counterweights. If the window has been painted, you will need to score the seams with either a hammer or chisel, to remove the panel without damaging it.
After you've removed the access panel, you'll see the two cast-iron sash weights in each pocket. Remove the weights from the front and back and tie the sash cords onto the weights using self-tightening knot. After you have tied the new cords, reconnect the sashweights and reset the system to work correctly.
Drafts
Sash windows add a hint of historical charm to older homes, but they also pose maintenance challenges. They can be difficult or impossible to open and close with a smooth, quiet operation. They can also be rattled by winds, and letting drafts in. These problems are often caused by swollen wood paint buildup, the sash cords have begun to rot. There are a number of simple and cost-effective ways to address these issues and keep your sash window operating correctly.
The first step to repair an old sash window is to take it apart it. Take off the sash and frame, and ensure that all parts are in good condition. Sand the wood to make it look better and stop drafts. A small amount of wax or silicone spray can help the sash slide more easily. If the sash still sticks to the wall, use a utility knife to cut any paint layers. A new set of tilt-pins could make the window more efficient.
Weights are passed over a system of pulleys to counterbalance the weight of windows with sash. These weights are typically cast iron and are reached via an access panel or pocket cover located in the inner box lining of the window frame. To prevent the weights from crashing down, the dividing strip is suspended within the frame to ensure that they don't collide.
Accessing these weights can be tricky, as the upper sash is sealed and can be nailed in the correct position. If you're patient and careful you can take the sash off with a pair of bar clamps that are spread apart. You may need to tap and jiggle it to free it, but once it's out you can inspect the sash and replace it if necessary with a new rope.
You can also change the balance of the sash to make it easier to open and close the window. It's a lot easier than you think to replace the double-hung balance on a window. You can do it yourself if have the right tools and a replacement kit.
Rotten sill
Even the most well-maintained windows will eventually show signs of decay. If the rot is only affecting the sill of the window, it may be possible to fix it. If the rot has spread to the frame and even into the interior and has damaged structural components it could be time to replace the window.
If you've found a decayed sill, it's important to replace it before it causes further damage to your window. The first step is to remove the sill plate that was previously installed and studs. If the studs bear loads they may require you to put in temporary supports. After you have removed the sill, take off any paint left on the sill plate. After cleaning the sill and replacing it with a new board and secure it to the studs.
A rotten sill can be unsightly and lead to costly repairs in the future. For example, it can cause the sash to move which is difficult to spot and could cause a cracked or bowed glass pane. In addition, a rotten sill can allow water to get into the wall, which could cause mold and other issues.
Replacing a sill that is rotten isn't as difficult as it sounds. It is crucial to maintain your window to avoid rot. Therefore, you must regularly clean the window tracks and sashes to keep them clear of dirt and debris. Apply a sealant to the frames of the windows to keep them dry. Lastly, you should use a dehumidifier in order to control the humidity levels in your home, which can stop wooden sashes from expanding or sagging.
Sashes that stick are a common issue for windows with sash. This issue can be fixed by applying a small amount of wax or silicone to the window tracks. This will allow them to slide easier. If the sashes have become stuck due to paint buildup you can use a utility knife to slice through the paint layers and remove the sashes.
Reinstalling the parting beads is another way to fix a stuck sash. If the sash is still sticking, you can also try draught-proofing the sash. This involves placing a strip of rubber between the frame of the sash and the sash. This helps to reduce airflow and improves acoustic qualities.
