Sash windows add a touch of elegance to any home. They can become drafty and difficult to repair as they age. Repairing sash windows is a great method to improve the functionality of your windows while keeping the original beauty of your windows.

The first step in repairing sash windows is to take off the "pocket covers". These are tiny pieces of wood that are placed in the lower part of the frame to allow access to the weights.

Sashes that have been damaged

If your sash window is damaged or leaking or leaking, you'll need to do more than patch the surface. You will save money by doing an extensive repair, especially if the home is older and has low insulation. Here are some common problems with sash windows and how much do wooden sash windows cost to fix it:

Stuck Issues

Broken Sash Cords

Some double-hung sashes from the past have metal or cotton cords that support the weights used to lift and lower the sashes. Over time, these cords can break, rendering it impossible to lift or keep the sash in place. Follow these steps to fix the problem:

Pull the sash to the right and then remove it from the frame. Cut the cord on the bottom of the sash, and then remove any nails sticking out from the end. With needle-nosed pliers, remove the nail and insert it into the side channel. Tuck the cord knot into the hole, and secure it using a nail set.

Re-install the sash and then install the staff beads. Be sure to leave enough slack in the cords to ensure optimal operation. Then, you can reinstall the balances and counterweights. Decorators caulk is an excellent way to prevent the risk of draughts. Apply small amounts of caulk between the bead boxes for staff.

Once the sash and frame are fully repaired, bed them in glazing putty. Glazing putty is typically made of linseed oil and chalk. Mix in enough chalk to make it workable, and not to stick to your hands. Allow the putty to dry completely before reinstalling the sash or painting the frame.

Broken sash cords

Old double glazed sash window-hung (two sashes) windows utilize cotton cords or metal chains connected to counterweights that support and keep the sashes in balance in the window jamb. As time passes, the cords might break, preventing the sashes from opening or close. This makes it difficult to raise the window or lower it. Replacing the sash's cords is an easy home fix that will solve the issue within less than a half hour.

Begin by removing your staff bead that separates the upper and lower sashes. You can remove the bead by using needle-nose pliers. A nail is inserted through the knot and into the sash's casing to secure it. Remove any nails that are rusty from the stop beads, and then clean off any paint, caulk and old cord traces around the groove of the sash.

To open the windows, pull one of the cords that run through the sash. When you've pulled the cord as far as it will go, mark the cord with a pencil and cut it into length with a knife. When you're done, ensure that the new cord matches with the groove in the sash and is secured to the sash frame by knotting it.

If the sash still isn't moving you can cut the cords using side cutters. After the sash is removed, you'll need to remove the access panels within the sash channels in order to expose the pulley system and counterweights. If the window is painted, you may need to score the seams with an axe and chisel to remove the access panel without damaging the paint.

After removing the access panel you will find two cast-iron sashweights in each pocket. Remove the weights on the back and front, then connect the sash cords to the weights using self-tightening knot. After tying the new cords, it is necessary to reattach the sash weights and reset the pulley system to ensure that it is working correctly.

Drafts

Sash windows add a hint of the past to older homes but they also pose problems with maintenance. They can be difficult to open or close and rattle in the wind and let drafts in. These problems are often caused by swelling of the wood or paint buildup, or the sash cords have begun to rot. There are a variety of easy and cost-effective methods to correct these issues and keep your sash window operating correctly.

Disassembling an old sash is the first step in repairing it. Remove the sash windows repair as well as the frame and make sure all parts are in good working order. Next, sand down the wood to enhance its appearance and prevent draughts. A small amount of silicone spray or wax can make the sash slide more easily. If the sash still sticks, use an utility knife to cut any paint layers. The addition of a new set tilt pins could also enhance the window's functionality.

Weights are pushed across pulleys in order to counterbalance the weight of the sash window. These weights are usually cast iron and can be accessible via an access panel or pocket cover that is located in the inner box lining of the window frame. A dividing strip is inserted inside the window frame to stop the weights from colliding.

It can be difficult to reach these weights as the upper sash can be painted shut and put in place. However, if you are diligent and cautious you can easily remove the sash with bar clamps, reversed to spread apart, to ease it out of its groove in the meeting rail. It could take a little bit of tapping and jiggling to get it out, but once you have it removed, make sure to check the sash cord and replace it with new rope (not cotton) in the event that it is required.

You can also alter the balance of the sash to make it easier to open and close the window. It's much easier than you imagine to replace the double-hung balance on a window. You can do it yourself if you have the right tools and replacement sash windows kit.

Rotten sill

Even the most well-maintained windows will eventually exhibit signs of rot. If the rot is only limited to the sill, it may be possible to fix the window. 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 damage to the window. The first step is to eliminate the sill plate that was previously installed and studs. If the studs are load-bearing, you may need to put in temporary supports. After removing the sill, clean off any paint remaining from the sill plate. After cleaning the sill then replace it with a new board and nail it into the studs.

A sill that is rotten can be ugly and cause future expensive repairs. It can, for example, cause the sash, which is difficult to notice to see, to move. This can lead to a cracked, bowed or damaged glass pane. A rotten sill may also allow water to enter the wall and cause mold.

It's not as difficult as it appears to fix a damaged sill. It is essential to maintain your window to avoid rot, therefore you should clean regularly the window tracks and sashes to keep them free from dirt and other debris. Apply a protective seal on the frames of the windows to keep them dry. You can also apply a humidifier to control the moisture in your home. This will stop wooden sashes from forming or swelling.

Sash windows are usually plagued by stuck sashes. To resolve them, you can apply small amounts of wax or silicone spray onto the window tracks to enable them to slide easily. If the sashes are stuck because of paint buildup, you can use a utility knife to slice through the paint layers and free the sashes.

Another option to resolve a stuck sash is to replace the parting bead. If the sash remains stuck you can try draught proofing it. This process involves placing strips of rubber between the sash and frame, which reduces air flow and improves the acoustic performance of the window.
