Sealing
Sash windows are beautiful in older buildings, but they require maintenance and are susceptible to issues like cracked putty, wet rot, and draughts. Repair, sealing or replacement of the windows in sash is a great method to eliminate these issues and improve the efficiency of energy.
Draughts are mainly caused by gaps between the sash and frame. They can also cause rattles and reduce sound-proofing. Sealing beads, specialty products, and secondary glazing can all be used to minimize the air leakage within the Sash.
A common issue is a gap between the top of the sash and the jamb frame or the bottom of the sill and the sash. This can result in water leaking into the wood and rotting of the wood and the growth of mould. The gap can be filled with silicone or polyurethane caulking or foam sealant.
If a gap in the window is preventing the windows from closing and opening without a hitch, it might be necessary to put in new sash runners or spring bronze. These are bronze strips that are stapled or nailed to the edges of the lower sash in order to prevent sideways rattle, and they can be purchased from DIY stores. Tubular vinyl weather-stripping is an alternative option, but it is prone to tear and affect the appearance of windows.
It is crucial to take measurements of the entire window opening before installing replacement sash runner. It is recommended to take measurements from the top of the sash to the horizontal line of the meeting rail and from the bottom of the 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 the gap between frame and sash is typically wider around the leading edge. It can be draught-proofed by using a strip of V-strip that is self-adhesive. However it is essential to take this into consideration when measuring and cutting the material.
The strip should be cut at the top of the sash with an inch more on each side to allow movement. It should be trimmed square and positioned so that the ends are aligned to the angle of the window sill. Make sure to use stainless steel screws since brass may rust. Also, use high-quality silicone or polyurethane glue.
Refurbishment
The windows with sash are a stunning historical feature in many homes. However, despite their beauty these windows are prone to a myriad of issues. The most frequent issues are rattling, stickiness or draughts. Frames that are rotting and meeting rails as well as broken glazing bars, faulty frames, or rotten weights are all causes of problems. If these issues occur, it's time to consider a sash repair or replacement.
Refurbishment is more costly than replacing the sash but it will restore your sash's look and function to the same level in its original condition. Refurbishment involves lining the meeting rail as well as the sash box with traditional putty and fixing 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 put in brush pile weather strip to reduce the noise of rattling.

If a replacement sash required It can be made using the same design to match your existing frame. This will help preserve the style and character of your property. This is especially important for listed properties where any changes to the windows will require planning permission.
Before putting the new window in place before installing it, make sure you check the metal tabs against those on the sash that was previously used (see below). If they're different shapes, the new sash will not fit properly into the slots of the window frame.
When a window is damaged it is crucial to decide between repair or replacement, because each type of work will involve a different level of expertise and cost. If a large portion of the glass in a sash is missing then replacing it will be a better alternative. If the glass is damaged in a small area or a sill is rotting, then a repair would be better.
Replacement
While many homeowners are keen to keep their old windows in good condition, deterioration could eventually result in problems like rattles, draughts or even broken glass. These issues usually lead to a replacement as the only logical solution. However, there are ways to improve sash windows, beyond simply replacing them, such as installing draught proofing and secondary glazing.
It's important to consider the severity of a issue, since it might not be feasible to replace a complete window. For example, a foggy glass issue typically occurs within the sash and can usually be solved without tearing out the entire frame. It is usually possible to fix a weak seal using a couple of simple fixes, rather than tearing out the entire frame and reinstalling it.
Sash windows are extremely complex in design and feature many moving parts. This is why it can be a challenge to remedy some common problems like sash cords that are snapped or broken panes. Resolving these issues often requires dismantling the window frame, which isn't something that most homeowners would want to tackle on their own. Many homeowners opt to work with a professional due to these reasons.
Specialists can restore sash window frames to their original glory or make them more up-to-date with modern energy standards. This may include reconditioning frames and installing secondary glazing, which will stop heat out of the window. You can also add a brush-pile strip in order to minimize drafts and stop the window from rattling.
To begin a repair project take out the window stops (the moldings in front of the lower sash). Next, loosen the staff bead and pull out the lower sash. Remove the chains or cords on both sides. Then, remove the sash weights from bottom of the cavity and take them off. Keep the hardware in a secure place. Soften any old filler or hardened putty with a heat gun and scrape it off with a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray. Install the parting beads and reinstall upper sash.
Repair
It is essential for homeowners to make a decision on whether to repair or replace their sash windows. Although modern replacements can provide a host of benefits but the original features of a home that was built earlier give personality and value to the property and are generally less expensive to fix than replacing them. Maintaining them in good shape can help save on energy costs. Sash windows are vulnerable to drafts, rattles, and condensation. These issues can lead to higher costs for energy and 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 even draughty. It is best to leave the repair of window sash to a professional because they require extensive dismantling. With the right tools and knowledge it's possible to repair an old sash window yourself. Adam shows Jess how to begin:
Remove any security fittings just in front of the lower window sash. Then, remove the staff bead, then take the sash off the bottom. Take the chains and cords from both sides, and tie them in a way that they can't be pulled back by the weights attached. It's time to remove the upper sash. Take out the sash stops which is a thin vertical strip of wood that holds the sash. Also, take off any paint-encrusted hardware. The sash should be pulled back to reveal the weight. It is a heavy iron or lead cylinder that is concealed in a cavity and is supported by an elastic cord. To stop the sash from falling into the void, you must pierce it using 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 scrape off any paint from the sash stops with the help of a utility knife. Reattach the stops once the sashes are reinstalled. Use nails that are small enough not to puncture the balancing weight.
To reassemble the sash, put the top sash into its track first, and then the lower sash. Make sure the sash stops are aligned properly with the frame, and then reconnect the beads that separate if required. Finally, reattach the sash chain or cords and then re-attach the axles of the sash pulleys.
