Sash Windows Repair and Replacement
Sash windows that are older than 20 years can have many issues such as rattles and draughts. They could also be poorly constructed to be insulated. With a little effort they can be repaired to a high level of performance.
First, remove the seal with a utility knife. Then, take off the staff bead, then pull out the upper sash, taking off chains or cords and storing the hardware in a bag marked.
Sealing
Sash windows are beautiful in older buildings, however they require care. They are susceptible to issues like wet-rot, cracked putty, and draughts. Sealing, replacement or repair of the windows in sash is a great method to minimize these issues and improve energy efficiency.
Draughts are usually caused by gaps between the sash and frame. They can also trigger noise reduction and rattle. There are a variety of methods to reduce air leaks in the sash window, such as sealing beads, specialist products and secondary glazing.
A gap between the top and bottom of the sash, and the jamb frame is a common problem. This can lead to moisture leaking into the wood, which can cause rotting and the growth of mold. Seal the gap with silicone, polyurethane, or foam sealant.
If a gap is preventing the windows from opening and closing smoothly, it may be necessary to put in new spring bronze or sash runners. These strips of bronze are tied or stapled to the lower sash edges to prevent the rattling of the sides. They are available at DIY stores. Weatherstripping made of tubular vinyl can also be used, but it is more likely to tear and can detract the appearance of your window.
It is important to determine the size of the window opening prior to installing the new sash runners. It is best to measure from the top of the sash up to the horizontal centerline of the rail that connects them and from the bottom sash down to the sill. These measurements can later be transferred to new runners that will ensure an improved fit and performance of the window.
In older buildings the gap between the sash and frame is usually wider around the leading edge. It can be draught proofed with a strip of self-adhesive V-strips, but it is essential to take this into consideration when measuring and cutting the material.
The strip should be cut to the height of the sash, with an inch extra on each side to allow for movement. It should be cut squarely and placed to align with the angle of the sill. It is also essential to use stainless steel screws, since brass can rust and the best quality polyurethane or silicone adhesive.
Refurbishment
The sash is an attractive historic feature in many homes. They are beautiful, but they can be susceptible to issues. Rattling, draughts, sticking or leaks are all common problems. Rotting frames and meeting rails as and broken glazing bars, defective frames or weights that are rotten can cause issues.

Refurbishment may be more expensive than replacing the sash but it will restore your sash's look and functionality to the same level that it was in its original form. Refurbishment involves re-lining the meeting rail as well as the sash box using traditional putty, and then repairing any damage caused by the rot. It also involves painting the timber frame and re-glazing with traditional glass. A full refurbishment can also include adding draught proofing, re-attaching the sash furniture/ironmongery and replacing the parting bead (the dividing strip between the two panes of glass). In addition, it is recommended to install brush pile weather strips in order to minimize the rattling and increase insulation.
If a new sash is required It can be made using the same style to match the frame you have. This will help preserve the style and character of your property. This is especially important for listed buildings where any modifications to windows need planning permission.
Check the metal tabs of the new window with those of the old sash prior installing it (see below). If these are different shapes the new sash won't fit in the slots of the window frame.
It's important to decide whether to repair or replace the damaged window, since each will require a different level and level of expertise. For instance, if a sash window has a large piece of glass missing then replacing it is the best choice. However, if the glass is damaged in a small area or a sill is damaged, a repair would be the better option.

Remove the cords and chains from both sides, and tie them in a way that they can't be pulled back by the weights. It's time to remove the upper sash. The sash stops must be removed which is a thin vertical strip of wood that holds the sash. Also, take off any paint-encrusted hardware. Reverse the sash to reveal the weight. It is a massive iron or lead cylinder, which is tucked away inside a cavity and supported by cords. To prevent the sash falling into the void, pierce it using a nail, and then sacrifice the weight.
After the sashes are removed, clean the jambs and rails that connect them. Remove the glazing bars as well as the cords of the sash. Then using a utility knife take off any paint from the sash stop.
