Window Sash Repairs

Most homeowners don't think much about window sashes so long as they are able to open, close, and keep outside air out and the air inside in. Over time, window sashes can wear out and cause drafts, air leaks or even stuck sashes.

The artist uses the sash which is supported on an easel to work the glazing points into the gap. He also scrapes off paint and then applies a wood preservative on the frame.

Sash Weights

If your windows aren't closing and opening smoothly or are sluggish, a faulty counterbalancing system could be the cause. This could be due to a missing or damaged sash cord/chain, an unattached or misaligned sash weight, or a damaged pulley.

The sash weights are small boxes, typically constructed of cast iron that serve to support the sash as well as balance the window's counter-weight system. The sash weights are located at the bottom rails of every window frame. They are covered by wood panels that can be removed to reveal their location. The panels can be removed for access to the sash weight pockets to clean or repair them, or even replace them.

There may be an issue with the sashweights if had your windows with sash and case window repairs windows for over a period of time. They might lean or catch. This can be due to the weights being too heavy (they are supposed to be a little heavier than the top sash) or due to them being installed incorrectly (some people have disabled their weight systems by cutting them and taking them off to save money, or turning them in for scrap metal).

To fix this problem take out the stops (the trim that runs along the inside of the window at the point that it joins with the frame to keep it in position). Place them aside. It is important to do this slowly so as not to damage the appearance of the overlapping rails. You can then use a hammer or mallet to break the stiles and rails and check them for damage or any repairs that must be done.

After examining the rails and stiles of the sash, place some dust sheets on the floor and start working. Start by removing wood pegs using a pin-punch and hammer or screwdriver from the mortise-and-tenon joints. Once the pegs are removed, you can begin disassembling the sash by taking out the stop moldings for sash as well as removing the sash cord knots that are connected, and then removing the sash itself.

Next you will want to weigh the sash in order to figure out how much weight is required for the proper functioning. You can buy vintage replacement sashweights on the internet or in some home improvement stores. Be sure to purchase the right size to avoid under or over-weighing the sash.

Sash Cords

The majority of sash window problems result from damaged or worn sash cords. The weights exert constant pressure on the sash cords and this can cause them break over time. If the cords break, sashes will not be able to open and close easily. The problem may be caused by excessive force, ageing, lack of maintenance, or the accumulation of moisture. During window double glazed timber sash windows repairs, it's important to replace the old cords with new ones that are made from a material that will last and resist moisture.

Begin by removing the internal stops and the thin pieces of wood that hold the sashes in place, using a utility knife and a chisel. Remove the stops carefully of the sashes while keeping an eye on any that are cracked or broken. Once the stops are removed, you will be able to access the sash weights via an access panel cut into the frame's bottom, or by opening the jamb and removing the weight pocket cover.

Accessing the sash's cords requires some extra effort, but it's not difficult with the right tools and patience. Remove the old cords first by cutting them at their knots and then pulling them out. Then, take the sash from the frame and put it aside. Take off the staff bead, which is the nail that keeps the sash in place. Insert a nail of about a foot length into the hole. This will keep the sash on its place while you string counterweights.

Reattach the sash string after reinstalling upper timber sash window. Verify that the sashes move in a smooth manner and are in a balanced position. Reinstall the lower sash and repeat the process. Check that the sashes have been properly set and are moving smoothly.

Once you've completed installing the counterweights, reconnect the sash cords by putting the sash cord through the pulleys and threading the other end of the cord through a knot hole in the sash to secure it in place. Repeat this process for each side of the sash until all the cords are replaced and the sashes function normally again.

Drafts and air leaks

Over time, the materials that connect sash windows to the home's frame deteriorate, resulting in drafts and energy loss.

Examine the interface of the sash with the frame. This includes the parting beads, and the staff bead. Check the condition of the weather stripping (felt strips or foam tape) at these points to determine if they are intact and functional. If not, it needs to be replaced.

Examine the condition of glazing putty. It is a tough putty that is used to hold panes of glass that has been tempered in place. Check for cracks or crumbling that expose the sash to moisture, which can lead to mold issues and damage to the glass of windows.

Apply a fresh layer glazing putty to the inside of the window to fix the issue. To fix the glazing points, use a flat-bladed screwdriver to push them into position. Wrap a piece or fabric and then foam around each point. This acts as insulation against cold air.
