Sealing Sash windows look stunning in older buildings, but they require care. They can be affected by problems like wet-rot cracked putty and draughts. Sealing, replacement or repair of the windows in sash is a great way to reduce these problems and improve energy efficiency. The gaps between sash frame are the primary cause of draughts. They can also lead to noise reduction and rattle. There are a variety of methods to stop air leaks from the sash window, such as sealing beads, special products and secondary glazing. A common problem is a gap that exists between the top of the sash and the jamb frame, or the bottom of the sill and the sash. This can lead to moisture leaking into the wood, rotting it, and mold growth. Seal the gap with silicone, polyurethane or foam sealant. Installing a new sash runner, or spring bronze might be necessary in the event that a gap blocks the windows from closing and opening easily. These are strips of bronze that are stapled or nailed into the edges of the lower sash in order to prevent sideways rattle, and they are available at DIY stores. Tubular vinyl weather-stripping is another option but it is prone to tear, and can affect the appearance of a window. window repairs is crucial to measure the entire window opening prior to installing the new sash runners. It is best to take measurements from the top of the sash to the horizontal centerline of the rail that connects it, and from the bottom of the sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a good fit and a better performance of the window. In older structures the gap between the sash and frame is usually larger around the leading edge. It can be draught-proofed using a strip of V-strip that is self-adhesive. However, it is important to take this into consideration when cutting and measuring material. The strip should be cut at the top of the sash and with an inch added on each side to allow for movement. It should be trimmed to a square shape and then positioned in a way that the ends are matched to the angle of the window sill. Make sure to use stainless steel screws since brass may get rusty. Also, use a high quality silicone or polyurethane glue. Refurbishment The Sash window is a beautiful, historic feature of many homes. These windows are beautiful, but they can be susceptible to issues. Draughts, rattling, sticking or leaking are typical issues. The rotted frames and the meeting rails as along with broken glazing bars, faulty frames or weights that are rotten can cause issues. If you are experiencing any of these problems it's time to replace or repair your sash. Refurbishment is more costly than replacing the sash but can restore your sash's look and function to the same level that it was in its original form. It involves re-lining the meeting rail and sash box using traditional putty and repairing any damage caused by rot. It also includes re-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). It is also recommended to install brush pile weather strip to prevent the noise of rattling. If a replacement sash is required, it can be made using the same style to match your old frame. This will help preserve the traditional style of your home. This is especially crucial for listed buildings, where any changes to the windows need planning permission. Check the metal tabs of the new window with those of the old sash before installing it (see below). If the tabs are different shapes, the new sash won't fit properly into the slots of the window frame. It is important to decide if you want to repair or replace a damaged window, as each choice will require a different degree and amount of knowledge. If a significant portion of the glass in the sash is missing then replacing it will be the better alternative. If the glass is damaged in a tiny area or a sill is beginning to rot or rotting, then a repair could be more appropriate. Replacement Many homeowners want to keep their old sash window in good shape, but it is inevitable that deterioration will cause problems like draughts or rattles. Broken glass can also occur. These issues often lead to a replacement as the only logical solution. There are other methods to improve sash window performance than simply replacing them. These include installing secondary glazing and draught-proofing. It is important to determine the extent of a problem, as it may not be feasible to replace a complete window. For instance, a fogging glass issue typically occurs within the sash and is usually able to be resolved without ripping out the whole frame. It is often possible to fix a poor seal by making a few easy fixes, rather than ripping out the entire frame and reinstalling it. Sash windows are extremely complex in design and have many moving parts. This is why it can be a challenge to remedy some common problems such as snapped sash cords or broken panes. Many homeowners do not want to remove the window frame in order to repair these issues. For these reasons, many homeowners choose to work with a specialist. Specialists can restore sash window frames back to their original splendor or update them to meet modern energy standards. This could include reconditioning the frames and fitting secondary glazing to stop heat from the window. It is also possible to add an extra strip of brush pile to stop rattling and reduce drafts. To begin a repair, remove the window stops. (The moldings are located in front of the lower glass). Next, loosen the staff bead and remove the lower sash. Remove the chains or cords that are on both sides. Finally, remove the sash weights from bottom of the cavity and take them off. Store the hardware in a secure place. Soften any old filler, hardened putty, or filler by using a hot gun. Then scrape it away with a putty knife. Reassemble the window, attach the hardware and then lubricate the pulley axles using silicone or Teflon spray. Install the parting beads again and reinstall the upper sash. Repair It is important for the homeowner to decide whether to repair or replace their sash windows. Modern replacements have many benefits, but the original features of an older home can provide the character and value. They are also less expensive to repair rather than replace. Maintaining them in good condition can help lower the energy cost. Sash windows can be susceptible to drafts and rattles. This can result in higher energy bills and even damage to the frame and the sash. Sash windows are notoriously difficult to close and open, and the traditional sliding mechanism can become dislodged from its track or draughty. It's best to leave the repair of window sash to a professional since it requires extensive dismantling. But, with the right tools and knowledge it is possible to fix old sash windows yourself. Adam shows Jess how to start: Making the window come apart starts by removing any security fittings in front of the lower sash. Next, remove the staff bead, then take the sash off the bottom. Then, remove the cords or chains on both sides and knot them to prevent them being pulled back into the frame by the weights attached to them. It's now time to remove the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that supports the sash) and loosen any painted-covered hardware. Pull the sash to reveal the weight balancing, which is a heavy iron cylinder or lead that is enclosed inside a hidden compartment and anchored by a rope. To stop the sash falling into the void make a hole in it using nails and remove the weight. Once the sashes are free, clean out the jamb and meet rails, remove the glazing cords and sash bars, and remove any paint from the sash stops with a utility knife. When the sashes are back in place, you can reattach the stops using nails that are not too large to risk cutting the weight that is balancing. Reassemble the sash by inserting the upper sash on top of its track, followed by the lower sash. Verify that the sash stoppers and the frame are properly aligned. If needed, reconnect any parting beads. Reattach the sash cords or chains and then install the sash pulleys.
