Sealing Sash windows look gorgeous in older buildings, but they do need maintenance and are susceptible to problems like cracks in putty, wet rot and draughts. Sealing, replacement or repair of the windows in sash is a great method to eliminate these issues and improve energy efficiency. The gaps between the sash and frame are the primary cause of draughts. They can also lead to noise reduction and rattle. Sealing beads, specialty products, and secondary glazing may all be used to reduce the air leakage in a shutter. A gap between the top or bottom of the sash and the jamb frame, is an issue that is common. This can cause moisture to leak in, rotting wood, and mold growth. The gap can be filled by caulking made of silicone or polyurethane or foam sealant. Installing new sash runner or spring bronze could be necessary when a gap is preventing the windows from opening and shutting effortlessly. These strips of bronze are attached by staples or nails to the sash's lower edges to stop sideways rattling. They can be purchased at DIY stores. Tubular vinyl weather-stripping is another option however it has a tendency to tear and affect the appearance of a window. It is essential to determine the size of the window opening prior to installing the an alternative sash runner. It is best to measure from the top of sash up to the horizontal centerline of the rail of the meeting and from the bottom of sash down to the sill. These measurements can later be transferred to new runners which will ensure an improved fit and performance of the window. In older structures, the gap between frame and sash is typically greater around the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However it is crucial to consider this when cutting and measuring material. A piece of material should be cut to the length of the sash. There should be an additional inch for movement. It should be trimmed square and positioned in a way that the ends are matched to the angle of the window sill. Use stainless steel screws since brass will rust.

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 install brush pile weather strips to lessen rattle and increase insulation. If a new sash is required, it can be made with the same design to match your existing frame. This will maintain the heritage style of your property. This is especially important for listed buildings where any changes made to windows will require planning permission. Check the metal tabs of the new window to the old sash prior installing it (see below). If they are different shapes and sizes, the new sash will not fit inside the slots of the window frame. If a window has been damaged, it is crucial to decide between repair or replacement because each type of work will require a different degree of expertise and price. For example when a sash window has a large piece of glass missing, a replacement will be the best option.

Then, loosen the staff and remove the lower window sash. Remove the chains and cords from both sides. Then take the sashweights out of the bottom cavity of the weight. Keep the equipment in a secure place. Soften any old, hardened putty or filler using a heat gun, and scrape it off with a putty knife.

It's now time to take out the upper sash. Remove the sash stops and a thin strip of wood that holds the sash. Also, remove any painted-covered hardware. Unscrew the sash to reveal the balancing weight, that is a massive lead or iron cylinder enclosed in a hidden cavity and held by rope. To stop the sash from falling into the void, you must pierce it using a nail, and sacrifice the weight. After the sashes have been removed clean the jambs as well as rails that connect them. Remove the glazing bars and sash cords. Then using a utility knife take off any paint from the sash stop.
