Sash Window Repair

Sash windows add a classy aesthetic to a home. They can become drafty and difficult to repair as they get older. Sash window repairs are a great way of improving functionality and maintaining the original elegance.

The first step in fixing windows with sash is to remove "pocket covers". These are tiny pieces of wood that are placed low on the frame and permit access to the weights.

Sashes damaged by abrasions

If your sash window has been damaged or leaking it is necessary to do more that just patch the surface. A more thorough repair will save you money in the long run, particularly if you have a older home that is not well-insulated. Here are some common problems with sash windows and how to fix them:

Sticking Issues

If the sash does not fit snugly within the frame, it's difficult to open or close the window. This could result in rattling sounds and allow drafts into your home.

To repair this, you can use a utility knife to score and cut 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 oil that will help it move more smoothly.

Broken Sash Cords

In some instances, older double-hung sashes are made of cotton or metal cords to support the weights that raise and lower the sashes. Over time, these cords can break and make it difficult to lift the sash and keep it up. Follow these steps to repair it:

Move the sash right and then remove it from the frame. Cut the cord at the bottom of the sash. Remove any nails sticking out from the end. Take the nail off using needle-nose pliers and then reinsert it into the side channel. The knot should be tucked into the cord into the hole and secure it using an nail set.

Re-install the sash and install the beads for staff. Make sure you leave enough space on the cords to ensure the proper operation. Install the counterweights and balances. To lessen the chance of draughts, a small amount of decorators caulk may be placed between the staff bead and box.

Once the sash and frame are fully repaired, bed them in glazing putty. Glazing putty can be made with linseed and chalk. Mix in enough chalk to make it workable, and not to stick to your hands. Let the putty dry completely before reinstalling the sash or painting the frame.

Broken sash cords

Old double-hung (two sashes) windows are made of cotton cords or metal chains that are attached to counterweights to help keep the sashes balanced in the window jamb. As time passes, the cords may break, preventing the sashes from opening and closing, making it difficult to lower or raise the window. Replacing the sash cords is an easy home fix that will solve these issues in a matter of less than an hour.

Start by removing the staff bead, which separates the upper and lower sashes. A nail is typically driven through the knot and into the sash's casing to secure the bead in place, but you should be able to pull it free with needle-nose pliers. Remove any rusty nail from the stop beads and clean the caulk, old cord residue, and paint around the sash groove.

To open the window, pull on one of the cords that run through the sash window refurbishment and lift it up. When you've pulled the cord to the maximum extent it can be then mark the cord with pencil, and then cut it into length with an utility knife. When you're done, make sure the new cord is aligned with the groove in the sash and is tied to the frame of the sash secondary glazing with a knot.

If the sash is still too high to move it, you can use sharp side cutters to cut and remove the old cords. When the sash is completely free it is necessary to remove the access panel within the sash channel to expose the pockets for sash weights, the counterweights, and the pulley system. If the window has been painted, you will have to cut the seams using the hammer or chisel in order to remove the panel without damaging it.

After removing the access panel you will see two cast-iron sashweights in each pocket. Remove the one on the back and the one on the front. Then, tie each sash cord to a weight using self-tightening knot. After tying the new cords, you'll need to connect the sash weights again and reset the pulley mechanism to ensure that it is working correctly.

Drafts

Sash windows add a bit of the past to older homes but they also pose maintenance challenges. They can be difficult to open and close, rattle in the wind, and let drafts in. These problems are often caused by swelling of the wood paint buildup, the sash cords have begun to rot. There are many affordable and cost-effective solutions to repair these issues and keep your sash windows functioning correctly.

The first step in fixing an old sash window is to take it apart it. Remove the sash as well as the frame and ensure that the components are in good working order. Then, sand the wood to improve its appearance and prevent draughts. A small amount of silicone or wax spray can aid in allowing the sash windows repair to slide more easily. If the sash is still stuck, use a knife to cut through any paint layers to release it. A new set of tilt pins can also improve the window's performance.

A sash window functions by counterbalancing the weight of glass by using weights that are passed through a pulley mechanism. These weights, which are typically constructed of cast iron, are accessible via an access panel or pocket located on the inner box sash windows lining. A dividing strip is put within the window frame to keep the weights from colliding.

The process of removing these weights can be difficult, since the upper sash has been painted shut and is nailed into the correct position. However, if you're cautious and patient you can easily remove the sash with a pair of bar clamps, reversed so that they spread apart, to ease it out of the groove in the meeting rail. You may have to tap and jiggle to free it, but once it's out examine the sash and replace it with a new rope.

While you're at it you could also replace the sash balance to make the window easier to open and close. Replacing the balance of a double-hung sash is much simpler than it is, and you can do it yourself with the right tools and a replacement kit.

Rotten sill

Even the best-maintained windows will eventually show signs of rot. If the rot is only limited to the sill, it may be possible to restore the window. If it has progressed through the frame into the interior of the house and has caused structural damage it's likely the right time to replace it.

It is crucial to replace a damaged window sill before it causes damage to the window. The first step is to take off the sill plates and studs. You may need to install temporary support in the event that the studs bear weight. After you have removed the sill, take off any remaining paint on the sill plate. After cleaning the sill, replace it with the new one and nail it into the studs.

A sill that is rotten is not only unsightly but it could cause costly repairs in the future. It could, for instance cause the sash that is hard to see to notice, to shift. This could lead to a cracked, bowed or damaged glass pane. A rotten sill may also allow water to get into the wall, causing mold.

It's not as difficult as it seems to fix a damaged sill. To stop rot, you must keep the window free of debris and dirt. Install a seal of protection on the frames of the windows to keep them dry. You can also apply humidifiers to manage the humidity inside your home. This will prevent wooden sashes from forming or swelling.

Sticky sashes are a frequent problem with sash windows. You can fix this problem by applying a small amount of silicone or wax to the tracks of your windows. This will make them slide more easily. If the sashes have become stuck due to 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 put back in the parting bead. If the sash is stuck, you can try draught-proofing it. This involves placing a strip of rubber between the sash frame and the sash. This will reduce airflow and improves acoustic qualities.
