Sash Windows Repair and Replacement
Sash windows older than 20 years can have many issues, including draughts and rattles. They could also be inefficiently constructed to be insulated. A little attention can often restore them to a high standard of performance.
First, remove the seal of paint from the window stop using the knife of a utility. Then, take off the staff bead and remove the upper sash, taking off chains or cords and storing the equipment in a bag labeled.
Sealing
Sash windows are beautiful in old buildings, however they do need maintenance and are susceptible to issues like cracked putty, wet rot and drafts. Repair, sealing or replacement of the windows sash is an effective way to reduce these problems and increase energy efficiency.
Draughts are usually caused by gaps between the sash and frame. They can also trigger noise reduction and rattle. Sealing beads, specialty products, and secondary glazing may be used to limit 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 frequent. This can lead to the leaking of moisture the wood, rotting, and mould growth. The gap can be sealed with caulking made of polyurethane or silicone or foam sealant.
If a gap is hindering the windows from closing and opening easily, it could be necessary to put in new sash runners or spring bronze. These are strips of bronze that are stapled or nailed to the edges of the lower sash in order to prevent sideways rattle, and they are available from DIY stores. Tubular vinyl weather-stripping is an alternative option, but it has a tendency to tear and affect the appearance of windows.
When installing replacement sash runners It is crucial to take full measurements of the window opening. It is recommended to take measurements from the top of sash up to the horizontal line on the meeting rail and from the bottom of sash down to the sill. These measurements can be transferred to new runners, which will ensure an improved fit and performance of the window.
In older buildings there is a larger gap between the sash and the frame on the leading edge. It can be draught proofed by a self-adhesive V-strips, but it is important to consider this when measuring and cutting the material.
A strip should be cut to the length of the sash, and with an extra inch on each side to allow for movement. The strip should be cut square and placed in a way that the ends are matched to the angle of the window sill. It is also essential to use stainless steel screws, because brass is prone to rust, and high-quality polyurethane or silicone adhesive.
Refurbishment
The Sash window is a beautiful, historic feature of many homes. They are beautiful but they can also be susceptible to issues. Common issues include rattling draughts or sticking. The rotted frames and the rails that connect them, as well as broken glazing bars, defective weights or rotten frames can cause issues. If you experience any of these problems it's time to replace or repair your sash.
Refurbishment may be more expensive than replacing the sash, but it will bring back the appearance and functionality to the same level that it was in its original form. Refurbishment involves re-lining the meeting rail as well as the sash box with traditional putty, and then repairing any damage caused by the rot. Re-painting of the timber frame is also included, as well as 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). It is also recommended to put in brush pile weather strips in order to minimize rattling and improve insulation.
If the need for a new sash arises it can be constructed from like-for-like designs to match the frame of the previous one and preserve your property's heritage style. This is particularly crucial for listed homes where any changes to the windows will require planning permission.
Compare the metal tabs of the new window with the old sash prior to installing it (see below). If they're different sizes the new sash may not fit in the window frame slots.
If a window has been damaged, it is crucial to decide between replacement or repair, because each kind of work will require a different level of expertise and price. For example, if a sash window has a large piece of glass missing then replacement is the best choice. But when the glass has been damaged in a small area or a sill is decaying, a repair may be the better option.
Replacement
Many homeowners would like to keep their old sash windows in good condition, but the deterioration of the window will eventually cause issues such as rattles or draughts. Broken glass may also occur. These issues usually suggest replacement as the only sensible solution. However, there are ways to improve the sash windows beyond just replacing them, such as installing draughtproofing and secondary glazing.
It's important to consider the extent of a issue, since it might not be appropriate or even practical to replace an entire window. Foggy glass for instance, is usually caused by the sash and can be fixed without tearing out the entire frame. A leaky seal can often be remedied by a few easy fixes rather than an expensive full-frame tear-out and replacement.
Sash windows have a complex design that has many moving parts. This is why it can be a challenge to remedy some common problems, like snapped sash cords or broken panes. Solving these issues usually requires dismantling the window frame, which isn't a job the majority of homeowners would like to tackle themselves. Many homeowners opt to hire a specialist for these reasons.
Specialists can restore sash window frames back to their original glory or bring them up-to-date with modern energy standards. This could include reconditioning the frames and installing secondary glazing, to avoid heat escaping out of the window. It is also possible to add a brush pile strip, to stop rattling and reduce drafts.
To begin a repair start by removing the window stops (the moldings on the front of the lower sash). Then, loosen the staff bead and take off the lower sash. Remove the cords or chains on both sides. Finally, remove the sash weights and the bottom of the weight cavity and remove them. Place the hardware in a secure location. Heat gun to soften old, hardened filler or putty. Scrape it off using a putty blade. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray. Install the parting beads and reinstall upper sash.
Repair
The choice of replacing or repairing the sash window is a major one for the homeowner. Although modern replacements offer a host of benefits, the original features of an older home add character and value to the property and are often cheaper to fix than replacing them. Maintaining them in good shape can help lower energy costs. Sash windows can be susceptible to rattles and drafts. This can result in more expensive energy bills and can damage the frame and sash.
Sash windows are notoriously difficult to close and open as the traditional sliding mechanism can become dislodged from its track or draughty. Repairing a sash windows requires extensive dismantling of the frame of the window, so it's best left to professionals. With the right tools and experience, it is possible to repair an the old sash window yourself. Adam shows Jess the basics:
Remove any security fittings that are just in front of the lower window sash. Next, take off the staff bead, then pull out the bottom sash. Take the chains and cords from both sides, and tie them in a way that they can't be pulled back by the attached weights. Now window repair to remove the upper sash. Take out the sash stops which is a thin vertical strip of wood that is used to hold the sash. Also, take off any painted-covered 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 held by a cord. To stop the sash falling into the void, pierce it with an hammer and then sacrifice the weight.
When the sashes are untied, clean out the jamb and meet rails. remove the glazing bars and sash cords, and remove any paint from the sash stops using an utility knife. Reattach the stops when the sashes have been reinstalled. Use nails that are small enough not to puncture the balancing weight.
Reassemble the sash by inserting the upper sash first on its track, followed by the lower sash. Check that the sash stops and the frame are aligned correctly. If needed, reconnect any beads used for parting. Reattach the sash cords or chains and attach the sash pulleys.
