Sash Windows Repair and Replacement
Sash windows that are older than 20 years may have many issues such as rattles and draughts. They may also be poorly constructed to be insulated. With a little effort they can be repaired to their original performance.
First, take off the seal of paint using an utility knife. Then, remove the staff bead, then remove the upper sash by removing chains or cords and storing the hardware in a bag marked.
Sealing
Sash windows are beautiful in older buildings, but they require maintenance and can be subject to issues like cracked putty, wet rot, and drafts. It is possible to decrease energy loss and increase the efficiency of windows with sash by replacing them the windows, repairing or sealing them.
The gaps between sash frame are the main source of drafts. They can also cause noise and rattling, which can reduce soundproofing. Sealing beads, special products, and secondary glazing may all be used to reduce the air leakage within a sash.
A gap between the top or bottom of the sash and the jamb frame is a common problem. This can cause moisture to leak into the wood, rotting it, and mold growth. The gap can be closed by caulking made of silicone or polyurethane or foam sealant.
If a gap is hindering the windows from closing and opening smoothly, it may be necessary to put in new spring bronze or sash runners. These bronze strips are tied or stapled to the sash's lower edges to prevent the rattling of the sides. They can be bought at DIY stores. Tubular weatherstripping also can be used, but it tends to rip and can detract the appearance of your window.
When installing replacement sash runners It is crucial to measure the window opening. It is best to take measurements from the top of the sash up to the horizontal centerline of the rails that meet, and from the bottom of the sash to the sill. These measurements can be transferred to the new runners, which will help ensure a good fit and better operation of the window.
In older buildings the gap between sash and frame is usually greater around the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However, it is important to take this into account when measuring and cutting the material.
A strip must be cut to the width of the sash. There should be an extra inch each side to allow to allow for movement. It should be cut to a square shape and then positioned in a way that the ends are matched to the angle of the window sill. Use stainless steel screws as brass may rust. Also, make sure you use high-quality silicone or polyurethane glue.
Refurbishment
The sash is a stunning, historical feature of many homes. Yet despite their beauty, these windows are susceptible to a variety of problems. Rattling, draughts, sticking or leaking are typical issues. The rotting of frames and connecting rails, broken glazing bars, or damaged weights could cause a lot of trouble. When these problems occur it's time to consider repairs or replacements to your sash.
Refurbishment can be more expensive than replacing the sash but can restore the appearance and functionality to the same level in its original condition. Refurbishment involves lining both the meeting rail and the sash box with traditional putty, and repairing any damage caused by rot. Re-painting of the timber frame is also included, as is re-glazing 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). Finally, it's recommended to put in brush pile weather strips in order to minimize rattling and improve insulation.
If a replacement sash is needed, it can be made using the same style to match your old frame. This will preserve the traditional style of your house. This is especially important for listed properties where any changes made to windows will require planning permission.
Before putting the new window in before installing it, make sure you compare its metal tabs to those on the sash that was previously used (see below). If the tabs are different shapes, the new sash will not fit correctly into the slots of the window frame.
It's important to decide whether to repair or replace the damaged window, since each will require a different degree and amount of expertise. For instance, if a sash window has a significant piece of glass missing then replacing it is the best option. If the glass is damaged in a tiny area or a sill is rotting, then a repair would be more appropriate.
Replacement
Many homeowners want to keep their old sash window in good condition, however deterioration will eventually cause problems like rattles or draughts. Broken glass can also occur. This is why it's often the only solution to these issues. There are other ways to improve the performance of sash windows rather than replacing them. This includes installing secondary glazing and draught-proofing.
It is important to determine the extent of a issue, since it might not be appropriate or even practical to replace an entire window. A glass that is foggy, for example, is usually caused by the sash, and can be addressed without having to tear out the entire frame. A leaky seal can often be corrected with a few simple fixes instead of a costly full frame tear-out and replacement.

It may also be beneficial to put in a brush pile strip, to stop the rattling and decrease drafts.
To begin the repair, remove the window stops. (The moldings that are located in front of the lower glass). Then, loosen the staff bead and take off the lower sash. Remove the cords or chains on both sides. Finally, disconnect the sash weights from bottom of the cavity and remove them. Keep the hardware in a safe place. Soften any old, hardened putty or filler by using a hot gun. Then scrape it off with the help of a putty knife. Reassemble the window, reconnect the hardware and lubricate pulley axles using silicone or Teflon spray. Reinstall the parting bead, and reinstall upper sash.

The process of bringing the window apart begins by removing any security fittings in front of the lower sash. Next, take off the staff bead and take the sash off the bottom. Then, take the chains or cords on both sides and knot them to stop them from being pulled back into the frame by the attached weights. It's now time to remove the upper sash. Remove the sash stops and a thin wood strip that holds the sash. Also, take off any painted-covered hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder that is concealed inside a cavity and held by cords. To keep the sash from falling into the void, make a hole in it using nails and remove the weight.
After the sashes are removed clean the jambs as well as rails that connect them. Remove the glazing bars and the cords for the sash. Then using a utility knife take off any paint from the sash stop. Reattach the stops once the sashes have been reinstalled. Use nails that are small enough not to puncture the balancing weight.
To reassemble the sash, place the top sash onto its track first, and then the lower sash. Make sure the sash stoppers are properly aligned with the frame, and then reconnect the beads that separate if required. Reattach the sash chains or cords and attach the sash pulleys.
