Sash Window Repair

Sash windows can add a stylish aesthetic to a home. However, they can be drafty and uncomfortable due to age or wear. Repairs to sash windows can be a great option for improving functionality and maintaining the original appearance.

The first step in sash window repair is to remove the "pocket covers". These are tiny pieces of wood that sit low on the frame and permit access to the weights.

Sashes that have been damaged

If your sash window is damaged or leaking it is necessary to do more than just patch the surface. You can save money by doing an extensive repair, particularly if your home is old and has low insulation. Here are some of the most common issues with sash windows and how to fix it:

Problems with Sticking

It can be difficult to shut or open the window if the sash does not fit tightly into the frame. This could cause a rattling sound and allow drafts into your home.

To repair this, you can use a utility knife to score and cut off the paint line on the interior side of your sash. Be careful not to harm the wood. Then, you'll need to apply a sash lubricant which will help it move along smoothly.

Broken Sash Cords

In some cases, old double-hung sashes use either metal or cotton cords to support the weights that lift 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 repair it:

Move the sash right and remove it from the frame. Cut the cord at the bottom of the sash. Remove any nails sticking out of the end. With needle-nosed pliers, remove the nail and then insert it into the side channel. Incorporate the cord knot into the hole and secure it with an nail set.

Install the sash again and add the staff beads. Be sure to leave slack in the cords to allow for the proper operation. Last but not least, put back the counterweights and balances. Decorators caulk is a great way to reduce the amount of draughts. Apply small amounts of caulk between the bead boxes for staff.

When the frame and sash are fully repaired, bed them in glazing putty. Glazing putty is made by mixing chalk and linseed. Mix in enough of the chalk to make it workable and not to stick to your hands. Let the putty completely dry before applying the sash back and painting the frame.

Broken sash cords

To support and balance the sashes in older double-hung windows (two sashes), cotton cords or chains are tacked to counterweights. As time passes, the cords can break which prevents the sashes from opening or closing, making it difficult to raise or lower the window. Replacing the sash's cords is a simple home repair that can fix these problems within less than a half hour.

Take off the staff bead, which divides the upper and lower sashes. A nail is typically driven through the knot and then into the sash's casing to hold the bead in place, but you should be capable of removing it using needle-nose pliers. Remove any rusty nails from the stop beads, and then clean off paint, caulk, and old cord residue that has accumulated around the groove of the sash.

To open the window, pull on one of the cords running through the sash to lift it up. Once you've gotten the maximum distance you can mark the cord with a pencil and cut it using a utility knife. Once you're done, make sure that the new cord is aligned with the groove on the sash. Also, tie it to the sash by knotting a knot.

If the sash isn't moving, cut the cords with your side cutters. When the sash is completely free it is necessary to remove the access panel within the Sash Windows Repair channel in order to expose the pockets of sash window replacement weights, counterweights, and the pulley system. If the window is painted, you might need to score the seams using a hammer and chisel to remove the access panel without damaging the paint.

Once you've removed your access panel, you'll be able to see the two cast-iron sash sash weights inside each pocket. Take the one on the back and the other on the front, then tie each sash cord to a weight by using a self-tightening knot. Once you have tied the new cords, reconnect the sashweights and set the system to function properly.

Drafts

Sash windows are a great way to add some history to older homes. However, they can be difficult to maintain. They can be difficult to open and close and can rattle in the wind, and let drafts in. These issues are usually caused by swollen wood or paint buildup, or sash cords that have rotted. Fortunately, there are many affordable and cost-effective solutions to fix the problem and keep your sash windows functioning correctly.

The first step to repair an old sash window is to take it apart it. Take off the sash and frame, and check that all components are in good order. Then, sand 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 still sticks, use an utility knife to cut any paint layers. A new set of tilt pins can improve the window's performance.

Weights are pushed across a pulley system to balance the weight of a sash window. The weights, usually made of cast iron, can be accessed via an access panel or pocket located on the inner box lining. A dividing strip is inserted within the window frame to stop the weights from colliding.

It can be difficult to reach these weights as the upper timber sash windows can be sealed with paint and then put in place. However, if you are diligent and cautious, you can remove the sash with bar clamps, reversed so that they spread apart, to ease it out of the groove in the rails that meet. It may be necessary to jiggle and tap to loosen it, but once it's out, inspect the sash and replace it with a new rope.

You can also replace the balance of the sash to make it easier to open and close the casement window sash. Replacing the balance of a double-hung window is a lot easier than it is and you can do it yourself using the right tools and a replacement kit.

Rotten sill

Even the most well-maintained windows will eventually exhibit signs of rot. If the rot is only affecting the sill of the window, it might be possible to repair it. If, however, it has gotten into the frame into the interior of the home and has damaged structural members it's likely the right time to replace it.

If you've found a decayed sill, it is important to replace it before it causes damage to your window. The first step is to eliminate the old sill plate and studs. It is possible to put in temporary support when the studs are weighing. After removing the sill and washing off any remaining paint from the sill plate. When the sill is clean then replace it with a brand new board and attach it to the studs.

A rotten sill is not only unsightly but it could cause costly repairs in the future. For instance, it could cause the sash's to shift, which can be difficult to spot and could cause a cracked or bowed glass pane. A sill that is rotten may let water in the wall and cause mold.

Replacing a damaged or rotting sill isn't as difficult as it might sound. It is vital to maintain your window to avoid rot. Therefore, you should clean regularly the window tracks and sashes in order to keep them clear of dirt and debris. It is also recommended to apply a sealant to the window frames to guard them from moisture. You can also use a humidifier to control the humidity in your home. This will prevent wooden sashes sticking or swelling.

Sashes that stick are a common problem with sash windows. To fix them you can apply a small amount of wax or silicone spray to the window tracks to enable them to slide easily. If the sashes are stuck because of the buildup of paint, you can employ a utility knife to cut through the layers of paint and free the sashes.

Another method to fix a stuck sash is to put back in the parting bead. If the sash remains stuck it is possible to try making it draught-proof. This involves putting a rubber strip in the gaps between the sash and frame which decreases airflow and improves the acoustic performance of the window.
