Sash Window Repair
Sash windows add a touch of class to any home. They can become drafty and troublesome as they age. Sash window repair is a great option to increase the functionality and maintain the original look of your windows.
The first step in repairing sash windows is to take off the "pocket covers". These are small pieces of wood that are placed at the bottom of the frame and let the weights in.
Sashes that have been damaged
If your sash windows are damaged or leaking air, you'll need to do more than patch up the surface. A more thorough repair will save you money in the long run, particularly in the case of an older house that has poor insulation. Here are some of the most common issues that sash windows face and the way to fix it:
Problems with Sticking
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 cause a rattling sound and let drafts in your home.
To repair this, you can use a utility knife to cut and then cut away the paint line on the interior side of your sash. Be careful not to harm the wood. You'll then need to apply a sash lubricant which will help it move along smoothly.
Broken Sash Cords
Some double-hung sashes that are old have metal or cotton cords that support the weights used to raise and lower the sashes. Over time, the cords may break, making it difficult to lift or keep the sash in place. Follow these steps to fix it:
Then, pull the sash to the right and then remove it from the frame. Cut the cord on the bottom of the sash. Remove any nails that are sticking out from the end. With needle-nosed pliers, remove the nail and insert it into the side channel. The knot of the cord should be tucked into the hole and secure it with the nail set.
Re-install the sash and install the staff beads. Be sure to leave slack in the cords to ensure the proper operation. Reinstall the balances and counterweights. To reduce draughts, a small amount of decorators caulk may be applied between the bead of the staff and the box.
Once the sash and frame are completely repaired, you can bed them in glazing putty. Glazing putty is typically made of linseed oil and chalk. Mix with enough chalk to make the putty usable and not stick to your fingers. Allow the putty to dry completely before applying the sash back and painting the frame.
Broken sash cords
Old double-hung (two sashes) windows are made of cotton cords or metal chains attached to the counterweights that support and keep the sashes balanced in the window jamb. As time passes, the chains could break, which stops the sashes from opening or closing, making it difficult to raise or lower the window. The sash cords can be replaced in less than hour.
Remove the staff bead that divides the upper and lower sashes. A nail is usually driven through the knot and then into the sash's casing to keep the bead, but you should be able to pull it free by using needle-nose pliers. Remove any nail that is rusty from the stop beads and then clean the caulk, old cord residue, and paint around the sash groove.
To open the window, pull one of the cords through the sash. When you've pulled the cord as far as it will go make a mark on the cord using pencil, and then cut it to length using a knife. When you finish making sure that the new cord matches with the groove of the sash and is connected to the frame with a knot.
If the sash remains too high to move then you can use your sharp side cutters to cut off and remove the old cords. Once the sash has been liberated, you'll have to take off the access panels within the sash channels, exposing the pulley system and counterweights. If the window is painted you might need to score the seams using the hammer and chisel in order to remove the access panel without damaging the paint.
Once you've removed your access panel, you'll be able to see the two sash weights made of cast iron inside each pocket. Remove the weights on the back and front and then connect the sash cords to the weights with a self-tightening knot. After you've tied the new cords, you can reattach the sashweights and set the system to function properly.
Drafts
Sash windows are a fantastic option to add a touch of historical charm to older homes. However, they can be difficult to maintain. They can be difficult to open or close and can rattle in the wind, and let drafts in. These problems are often caused by painted or swollen wood, or rotted sash cords. There are a number of simple and cost-effective methods to fix these problems and keep your sash window operating correctly.
Disassembling an old sash is the first step in repair it. Take off the sash and frame and make sure all parts are in good condition. Then, sand the wood to enhance its appearance and to prevent drafts. A small amount of wax or silicone spray can help the sash slide more easily. If the sash remains stuck, use a utility knife to cut through any paint layers to release it. A new set of tilt pins can also help improve the window's operation.
A sash window functions by counterbalancing the weight of the glass by using weights that are pushed through the pulley system. These weights, typically made of cast iron can be accessed through an access panel or pocket located within the lining of the box. To stop the weights from falling down, the dividing strip is suspended within the frame to ensure that they don't collide.
It can be difficult to access these weights, since the sash's upper part can be sprayed shut and fixed with nails. If you're cautious and patient you can take off the sash with bar clamps that are reversed and break apart, allowing it out of its groove in the rail that connects it. It may take a few jiggling and tapping to get it out but once you've got it removed, make sure to inspect the sash cord and replace it with a new rope (not cotton) in the event that it is required.
While you're at it, you can also replace the balance of the sash to make it easier to open and close. 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 best-maintained windows will eventually exhibit signs of decay. If the rot is only limited to the sill, it might be possible to repair the window. If it has progressed through the frame into the interior of the house and has damaged structural components it's likely the right time to replace it.
sash window cost is important to replace a rotten window sill before it causes further damage to the window. The first step is to remove the sill plates and studs. It is possible to put in temporary support when the studs are weighing. After removing the old sill and cleaning any remaining paint from the sill plate. After the sill has been cleaned, replace it with a brand new board and attach it to the studs.
A rotten sill is not just 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 notice, to shift. This can lead to cracks, bowed or damaged glass pane. A rotten sill may also let water in the wall, causing mold.
Replacing a damaged or rotting sill isn't as difficult as it might sound. To stop rot, you must keep the window clean and free of debris and dirt. You should also apply a sealant that is protective on the window frames to shield them from moisture. In addition, you must use a dehumidifier to regulate the moisture levels in your home, which can prevent wooden sashes from swelling or sagging.

Another method to fix a sticking sash is to put back in the parting bead. If the sash remains stuck you can try draught proofing it. This is done by placing a piece of rubber between the sash frame and the sash. This helps to reduce airflow and improves acoustic qualities.
