Sash Windows Repair and Replacement Older sash windows be prone to a variety of issues, including draughts rattles and poor insulation. A little attention can often restore them to a top level of performance. First, take off the paint seal using an utility knife. Then, take off the staff bead and pull out the upper sash and remove the cords or chains and storing hardware in a labeled bag. Sealing Sash windows are beautiful in old buildings but they require regular maintenance and can be subject to problems like cracks in putty, wet rot, and drafts. Repair, sealing, or replacement of the sash window is an effective method to minimize these issues and improve energy efficiency. Draughts are mainly caused by gaps between the sash and the frame. They can also cause noise reduction and rattling. Sealing beads, special products, and secondary glazing may all be used to reduce the air leakage inside the shutter. A gap between the top or bottom of the sash, and the jamb frame, is a common problem. Lewisham window repair can lead to water leaking into the wood and rotting of the wood, and mould growth. The gap can be filled with caulking made of polyurethane or silicone or foam sealant. If a gap in the window is preventing windows from opening and closing without a hitch, it might be necessary to put in new spring bronze or sash runners. These strips of bronze are stapled or nailed to the sash's lower edges to prevent sideways rattling. They are available at DIY stores. Tubular vinyl weatherstripping can also be used, however it is more likely to tear and can detract the appearance of your window. When replacing sash runners it is essential to take full measurements of the window opening. It is recommended to take measurements from the top of the sash up to the horizontal line on the meeting rail and from the bottom sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a perfect fit and better operation of the window. In older structures, there is a wider gap between the sash and the frame on the leading edge. It is possible to draught-proof it using a strip of V-strip that is self-adhesive. However it is essential to take this into consideration when cutting and measuring material. The strip should be cut at the top of the sash with an inch extra on each side to allow for movement. It should be cut square and placed so that the ends are aligned to the angle of the window sill. It is also important to use stainless steel screws since brass can rust and high-quality silicone or polyurethane adhesive. Refurbishment The sash window is an elegant, historic feature of many homes. But despite their beauty, windows like sash windows can be prone to a range of issues. Rattling, draughts, sticking or leaking are common issues. Rotting frames and meeting rails as well as broken glazing bars, faulty weights or rotten frames can all cause problems. If you encounter any of these issues, it is time to replace or repair your sash.

Re-painting of the timber frame is also included, as is the re-glazing process using 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).

If a large portion of the glass in the sash is missing replacing it is an option. If the glass is only damaged in a small region or a sill has begun to decay, then a repair would be better. Replacement While many homeowners are keen to keep their old sash windows in good working condition, the deterioration of the windows can cause issues such as draughts, rattles, or even broken glass.
