Sash windows are beautiful in older structures, but they require maintenance. They can be affected by issues such as wet-rot, cracked putty and draughts. Repair, sealing, or replacement of the sash window is an effective method to minimize these issues and increase energy efficiency.
The gaps between sash frame are the primary cause of draughts. They can also lead to noise reduction and rattling. There are a variety of methods to limit air leaks within a sash window, including sealing beads, special products and secondary glazing.
A common problem is a gap between the top of the sash and the jamb frame, or between the bottom of the sash and the sill. This can result in water leaking into the wood, rotting of the wood, and mould growth. The gap can be closed with caulking made of polyurethane or silicone or foam sealant.
Installing new sash runner or spring bronze may be required when a gap is preventing windows from closing and opening effortlessly. These strips of bronze are tied or stapled to the lower sash edges in order to stop sideways rattling. They can be bought at DIY stores. Weatherstripping made of tubular vinyl can also be used, but it is prone to tear and may alter the look of your window.
It is important to take measurements of the entire window opening prior to installing a an alternative sash runner. It is recommended to take measurements from the top of the sash to the horizontal centerline of the meeting rail, and from the bottom of the sash down to the sill. These measurements can then be transferred to new runners which will ensure the best fit and function of the window.
In older buildings there is a greater gap between the sash and frame at the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However it is crucial to take this into consideration when measuring and cutting the material.
A piece of material should be cut to the length of the sash, and with an additional inch on each side to allow movement. It should be trimmed to a square shape and then positioned so that the ends are aligned to the angle of the window sill. It is also crucial to make use of stainless steel screws as brass can rust, and high-quality polyurethane or silicone adhesive.
Refurbishment
The Sash window is a beautiful historical feature in many homes. However, despite their beauty these windows are susceptible to a variety of problems. Draughts, rattling, sticking or leaks are all common problems. The rotting of frames and meeting rails, broken glazing bars or faulty weights can cause a lot of trouble.

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). Finally, it's recommended to put in brush pile weather strips to reduce rattling and improve insulation.
If a new sash is required it can be constructed using similar designs to the old frame and maintain the character of your house. This is particularly important for listed properties where any changes made to the windows will require planning permission.
Before putting the new window on, it's best to examine its metal tabs with those on the sash that was previously used (see below). If these are different shapes the new sash will not fit in the window frame slots.
It is crucial to determine whether to replace or repair the damaged window, since each will require a different level and level of knowledge. For instance the case of a sash windows that has a large piece of glass missing, a replacement will be the best choice. If the glass is damaged in a small region or a sill is beginning to rot and needs to be repaired, then a repair will be better.

Adam shows Jess the basics:
Making the window come apart starts by removing any security fittings that are in front of the lower sash. Then, take off the staff bead. Then, take out the sash at the bottom. Then, take the chains or cords on both sides and tie them to stop them from being pulled back into the frame by the attached weights. Now it's time to remove the upper sash. The sash stops must be removed and a thin strip of wood that is used to hold the sash. Also, take off any hardware that has been painted. Unscrew the sash to reveal the weight balancing, which is a large iron cylinder or lead that is enclosed inside a hidden compartment and secured by rope. To prevent the sash falling into the void, you must pierce it with a nail and then let the weight go.
After the sashes have been removed, clean the jambs and meet rails. Remove the glazing bars and the cords of the sash. Then, using a utility blade take off any paint from the sash stop. Once the sashes are back in place, reattach the stops using nails that are small enough to prevent damaging the balancing weight.
Reassemble the sash by inserting the upper sash first on its track, then the lower sash. Make sure that the sash stops are properly aligned with the frame, and then reattach the parting beads if needed. Finally, reattach the sash cords or chains and re-install the axles of the sash pulleys.
