Sash Windows Repair
Pam tries to salvage as much of the original window as she can. She uses a heatgun set to medium and an nozzle guard to soften the old, hardened glazing compound (putty) and then a putty blade to scrape it off.
She then knots the bottom sash cords to ensure they don't pull into pockets for weights, and then removes its metal hardware. She then puts it in a bag with a label.
Repairing the Sash
Old wood windows even if well maintained and repaired, might not be able to open and close as smoothly as they ought to. This issue could be due to the hardware being misaligned, which is relatively easy to fix. Alternatively, it could be due to the wood swelling and shrinking due to changes in humidity levels in the surrounding. Wood window sash replacement will allow the window to operate more smoothly and efficiently.
To remove the lower sash, first find the wooden peg(s) that connect the stile and rail together. To ensure that the sash is not damaged you can use a soft-faced mallet or hammer to gently separate the rail from the stile. Then, take off the muntins (the vertical and horizontal pieces that separate the glass panes). After you have removed the muntins, lift the sash up and rest it on the table or work bench. Take the sash cords off. Cut them below the point they are attached.
Once the window has been thoroughly cleaned, it's the time to start reassembling it. The author beds each sash reassembled using glazing compound - using the small pry bar and a stiff-bladed knife. She then secures them with the glazier's points (one point on each side of the sash). In the end, she puts on a sash stop to keep it from being pulled completely down.
If you're using the sash cords it's a good idea to connect the back end of each to a nail or pin protruding from the top of the staff bead - this will hold the weight in place until you can attach the other end to the sash. Once the cord is attached then, temporarily nail or pin the weight to the staff bead, and leave the head protruding to stop the weight from slipping off when you're doing this.
After the sash has been assembled, it is put in its frame. The vinyl track can then be put back in place. Finally, the terminals for the lock are replaced by releasing the pawls of each terminal and twisting them in the opposite direction to reset the tension.
Restoring the Frame
The elements can have a big impact on both the interior and exterior of your sash windows and it is often the situation that the frame will be more damaged than the sash. The frame is more vulnerable to the elements, particularly in older homes where sills were not angled as they are now. This can result in water residue accumulating on the sill that, over time, can cause the wood to begin to rot. If left unattended the rot may spread to the the frame and compromise the structural integrity of the frame.

Draught-proofing your window is a further way to enhance its acoustic properties. To limit the amount of air that is able to pass between the glass panes gas-filled vapors are introduced into the gaps.

Sash windows are a complicated arrangement of wood components that include sash horns with sharp edges and sash guts which surround the glazing, scotia moldings and precision-crafted employees beads and parting beads. All these parts have to be able to work seamlessly, which requires precise millimetre gap sizes as well as an invisible system of pulleys and weights.
