Sealing Sash windows look stunning in older buildings, but they require maintenance. They are susceptible to issues like wet-rot, cracked putty, and draughts. It is possible to decrease energy loss and increase the efficiency of windows made of sash by replacing, repairing or sealing them. Draughts are mostly caused by gaps between the sash and the frame. They can also trigger noise reduction and rattle. Sealing beads, special products, and secondary glazing may all be used to minimize the air leakage in the Sash. A gap between the top or bottom of the sash and the jamb frame is an issue that is common. This can lead to water leaking into the wood the wood, rotting and the growth of mould. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant. Installing a new sash runner, or spring bronze may be required when a gap is preventing windows from opening and shutting easily. These strips of bronze are tied or stapled to the lower sash edges to prevent sideways rattling. They are available at DIY stores. Tubular weatherstripping also can be used, but it is more likely to tear and can alter the appearance of your window. It is crucial to determine the size of the window opening before installing an alternative sash runner. It is best to measure from the top of the sash to the horizontal line of the rails that meet and from the bottom of the sash down to the sill. These measurements can be transferred to new runners, which will ensure a better fit and operation of the window. In older structures, the gap between sash and frame is usually larger around the leading edge. It can be draught-proofed by using a strip of V-strip which is self-adhesive. However, it is important to consider this when measuring and cutting material. A strip must be cut to the length of the sash, with an extra inch for movement. The strip should be cut square and positioned in a way that the ends are aligned to the angle of the window sill.

If the need for a new sash arises, it can be made from like-for-like designs to match the old frame and maintain the character of your house. This is particularly important for listed buildings where any modifications made to the windows will require planning permission.

If a window is damaged, it is essential to decide between repair or replacement, since each kind of repair will require a different degree of expertise and expense.

For instance, a fogging glass issue is usually a problem within the sash itself and is usually able to be resolved without tearing out the entire frame. A leaky seal can often be corrected by a few easy fixes rather than an expensive full-frame tear-out and replacement. Sash windows are a complicated design with many moving parts.

This may include reconditioning frames and installing secondary glazing to stop heat loss out of the window. It can also be helpful to add a brush pile strip to stop rattling and reduce drafts. To begin a repair project, remove the window stops (the moldings on the front of the lower sash). Next, loosen the staff bead, then take off the lower sash. Remove the chains or cords on both sides. Then, remove the sash weights from the bottom of the weight cavity and remove them. Store the equipment in a secure location. Soften any old filler, hardened putty, or filler by using a hot gun. Then scrape it off with the help of a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray.

The sash can be pulled back to reveal the weight balancing, which is a heavy iron cylinder or lead that is enclosed in a hidden cavity and anchored by rope. To keep the sash from falling into the void, hit it with a nail and sacrifice the weight. When the sashes are untied clean the jamb and meet rails. remove the glazing bars and sash cords and remove any paint from the sash stops with an utility knife. When the sashes are back in place, reattach the stops using nails that are small enough to prevent cutting the weight that is balancing. To reassemble the sash put the top sash into its track first, and then the lower sash. Make sure that the sash stops are aligned properly with the frame, and then reattach the beads that separate if required. Reattach the sash chains or cords and install the sash pulleys.
