Window Sash Repairs

Sash Weights

If your windows aren't closing and opening smoothly, or are stuck the way they should, a defective counterbalancing system could be the reason. This can occur due to a missing or damaged sash cord/chain or an unattached or misaligned sash weight, or a damaged pulley.

The sash weights are small boxes constructed of cast iron that serve to support the sash as well as help balance the counter-weight system of the window. They are found in the bottom rails of every window frame, and are covered by an access panel made of wood which can be opened to reveal their whereabouts. These panels can also be removed to gain access to the weight pockets in the mock sash upvc windows for cleaning, repairs or replacement.

If you've been using sash windows for a long time you likely have a problem with the sash weights that cause them to lean or catch. The weights can be too heavy (they should be slightly heavier than top sash) or they've been installed incorrectly.

To resolve this issue, remove the stops (the trim that runs along the inside edge of the window where it meets the frame to hold it in position). Put them away. It is important to do this slowly so as not to harm the shape of the two rails. Then you can use a hammer or mallet to break up the rail and stiles and examine them for damage or any repairs that must be done.

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

The next step is to weigh the sash in order to determine the amount of weight it requires for functioning. You can find old weights for replacement on the internet or at a few home improvement stores, but you should be sure to purchase the right size to ensure not to under or over weigh the sash.

Sash Cords

Sash cords that are worn or broken can cause problems with the sash window. The weights exert constant pressure on the sash cords and this can cause them break over time. If cords break, sashes won't be able to open and close easily. The problem could be caused by a variety of factors, including excessive force, aging, the lack of maintenance and moisture buildup. During window sash repairs it is essential to replace the old cords with new ones made of materials that last and resist moisture.

Begin by removing the inner stop strips, the thin wood strips that hold the sashes into their place Utilizing a utility blade and a the chisel. Remove the stops out of the sashes with care, and keep an eye out for any broken or cracked ones. After removing the stops you can gain access to the sashweights by opening the jamb or taking out the weight pocket.

It requires a bit of work to reach the sash cords, but with the right tools and a bit of patience, it's not difficult. First, you must remove the old cords by cutting them near their knots and pulling them free. Then, remove the sash from the frame and set it aside. When the sash is removed and you have pulled it down, grab the staff bead (the nail that stops the sash from falling) and insert the nail, which is about a foot long into the hole in the staff bead. This will temporarily keep the sash from falling as you string the counterweights.

Reattach the sash strings following installing the upper sash. Check that the sashes move smoothly and are in a balanced position. Then, you can reinstall the lower sash, and repeat the process, ensuring that the sashes are correctly sitting and moving smoothly.

Reattach the sash cable after you have installed the counterweights. Thread the cord through the pulleys, and then through the knot hole in the sash. Repeat this process for both sides of the sash, making sure that the sashes function normally again.

Take a look at the condition of the glazing putty. It's a hard putty used to hold panes of glass that has been tempered in place. Look for cracks and crumbling that could expose the sash's exterior to moisture. This can cause mold issues and damage to the glass.

To fix the issue, apply a bed of fresh glazing putty onto the inside of your window. To secure the glazing points, make use of a flat-bladed screwdriver push them into the right position. Wrap a fabric or piece and then foam around each point. This will act as an insulation against cold air.

After you have removed the parting beads, you'll have to remove the pockets. They are pieces of wood within the frame, lower down, that allow access to weights for the sash and are typically nailed in place - they can also be stuck with paint, so you have be extra cautious.
