Why We Love Sash Windows Repair (And You Should Also!)
Sash Windows Repair and Replacement
Older sash windows be plagued by a variety of problems including draughts, rattles and poor insulation. With a little attention they can be repaired to a high level of performance.
First, knock off the paint seal from the window stop using a utility knife. Then remove the staff bead, then remove the upper sash and remove the cords or chains and storing hardware in a bag marked.
Sealing
Sash windows can look stunning in older buildings, but they do need maintenance and can be subject to issues like cracked putty, wet rot and drafts. Sealing, replacement or repair of the windows in sash is a great method to eliminate these issues and improve energy efficiency.
The gaps between the sash and frame are the primary cause of drafts. They can also lead to rattling and reduced sound-proofing. Sealing beads, specialist products, and secondary glazing can be used to limit the air leakage within the shutter.
A gap between the top or bottom of the sash, and the jamb frame, is a common problem. This can result in moisture leaking in, rotting of the wood and the growth of mould. The gap can be closed with silicone or polyurethane caulking or foam sealant.
Installing new sash runner or spring bronze may be required if a gap prevents windows from opening and shutting smoothly. These are a type of bronze that are stapled or nailed onto the edges of the lower sash to stop sideways rattle. They are available from DIY stores. Tubular vinyl weather-stripping is an alternative option but it has a tendency to tear, and can affect the appearance of a window.
It is important to measure the entire window opening prior to installing the replacement sash runner. It is recommended to measure from the top of sash up to the horizontal centerline on the rail that connects them and from the bottom of sash down to the sill. These measurements can later 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 as well as the frame around the leading edge. It can be draught-proofed by using strips of V-strip that is self-adhesive. However it is crucial to take this into account when measuring and cutting material.
A strip must be cut to the length of the sash. There should be an extra inch for movement. It should be cut squarely and placed in accordance with the angle of the sill. It is also crucial to use stainless steel screws since brass can rust and high-quality silicone or polyurethane adhesive.
window repair is a stunning, historical feature of many homes. However, despite their beauty these windows are susceptible to a myriad of issues. Rattling, draughts, sticking or leaking are common issues. The rotted frames and the rails that connect them, as and broken glazing bars, defective frames, or rotten weights can all cause problems. If these issues occur, it's time to consider a sash repair or replacement.
Refurbishment can be a more costly alternative than replacing the sash, but it will improve the appearance and functionality of your sash window as good, if not superior to its original state. It involves re-lining the meeting rail and sash box using traditional putty and repairing any damage caused by rot. It also involves 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 minimize the noise of rattling.
If a replacement sash required it can be constructed using the same design to match your old frame. This will help preserve the traditional style of your home. This is particularly crucial for listed buildings, where any modifications to windows require planning permission.
Before you put the new window on, it's best to check the metal tabs against those on the sash that was previously used (see below). If the tabs are different shapes, the new sash won't fit properly into the slots of the window frame.
It is crucial to determine whether to repair or replace the damaged window, since each choice will require a different degree and cost of knowledge. If a large portion of the glass in a sash is missing, replacing it is an option. However in the event that the glass is damaged in a tiny section or a sill is damaged, a repair would be more appropriate.
Replacement

While many homeowners are keen to keep their old windows in good order, deterioration can eventually cause issues such as rattles, draughts or even broken glass. This is why replacing them is often the only solution to these problems. However, there are other ways to improve the sash windows, beyond simply replacing them, including installing draughtproofing and secondary glazing.
It is crucial to assess the severity of the problem, as it may not be feasible to replace the entire window. For example, a foggy glass issue is usually a problem within the sash itself and is usually able to be resolved without ripping out the whole frame. A poor seal can also often be remedied by a few easy fixes rather than an expensive full-frame tear-out and replacement.
Sash windows are quite complex in design and have a lot of moving parts. It can be a challenge to fix common issues like cracked panes or sash cables that have snapped. Many homeowners do not want to remove the window frame to fix these problems. This is why many homeowners choose to work with a specialist.
Specialists can restore sash window frames back to their original glory or bring them up-to-date with the latest energy standards. This can include reconditioning the frames and fitting secondary glazing, to avoid heat loss from the window. It may also be beneficial to install a brush pile strip to stop rattling and reduce drafts.
To begin a repair, take off the window stops. (The moldings that are on the side of the lower glass). Then you can loosen the staff, and pull the lower window sash. Take the chains and cords from both sides. Then, remove the sash weights and the bottom of the cavity and take them off. Place the hardware in a safe place. Soften any old filler, hardened putty, or filler using a heat gun, and scrape it off with a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys by using Teflon or silicone spray. Reinstall the parting bead and reinstall upper sash.
Repair
The choice to replace or repair windows with sash is a major one for homeowners. Modern replacements have many benefits however, the original features of an older house can add authenticity and value. They are also less expensive to repair instead of replacing. Maintaining them in good condition can help reduce the energy cost. Sash windows are prone to drafts, rattles, and condensation, and these issues can lead to higher costs for energy and damage to the frame and sash.
Sash windows can be difficult to open or close. The sliding mechanism may become sloppy or draughty. It is best to leave the repair of a sash windows to professionals since it requires extensive removal. With the right tools and knowledge it is possible to fix an the sash window that is old. Adam shows Jess the basics:
Remove any security fittings just in front of the lower window sash. Then, remove the staff bead. Then, remove the sash at the bottom. Then, take the chains or cords on both sides and tie them to prevent them being pulled back into the frame by the weights attached to them. It's time 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, remove any painted-covered hardware. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder that is hidden in a cavity and is held by cords. To stop the sash from falling into the void pierce it with a nail and then let the weight go.
When the sashes are untied, clean out the jamb and meet rails, remove the glazing cords and sash bars, and scrape off any paint from the sash stops with an utility knife. After the sashes have been put back in place, you can reattach the stops using nails that are small enough to prevent cutting the balancing weight.
Reassemble the sash by inserting the upper sash first into its track, followed by the lower sash. Make sure the sash stoppers are in the correct alignment with the frame, and reattach the beads for parting if necessary. Reattach the sash chains or cords and install the sash pulleys.
