Sash Windows Repair and Replacement


Older sash windows may be prone to a variety of problems including draughts, rattles and poor insulation. With a little care they can be repaired to a high level of performance.

First, scrape 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 chains or cords, and then storing the equipment in a bag labeled.

Sealing

Sash windows look gorgeous in older buildings, but they require regular maintenance and can be subject to issues such as cracks in putty, wet rot and drafts. It is possible to reduce energy loss and improve the efficiency of windows with sash by replacing them the windows, repairing or sealing them.

Draughts are mostly caused by gaps between the sash and the frame. They can also trigger noise reduction and rattle. Different methods can be employed to reduce air leaks in the sash window, such as sealing beads, specialist 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 could cause moisture to leak into the wood, rotting it and growth of mold. Seal the gap with silicone, polyurethane or foam sealant.

Installing new sash runner or spring bronze might be necessary if a gap prevents the windows from closing and opening easily. These are bronze strips that are stapled or nailed to the edges of the lower sash to stop sideways rattle, and they are available from DIY stores. Tubular vinyl weatherstripping can also be used, but it tends to rip and can detract the appearance of your window.

When installing replacement sash runners it is essential to measure the entire width of the window opening. It is best to take measurements from the top of the sash to the horizontal line of the meeting rail and from the bottom of the sash to the sill. These measurements can be transferred to new runners which will ensure the best fit and function of the window.

In older buildings the gap between the frames and sash is typically greater around the leading edge. It can be draught proofed by a self-adhesive Vstrip, however it is important to take this into consideration when measuring and cutting the material.

A strip must be cut to the length of the sash. There should be window repair for movement. It should be cut squarely and positioned to match the angle of the sill. Make sure to use stainless steel screws since brass may get rusty. Also, make sure to use a high quality silicone or polyurethane glue.

Refurbishment

The sash is an attractive historic feature in many homes. These windows are gorgeous but they can also be susceptible to issues. Draughts, rattling, sticking or leaking are typical issues. The rotting of frames and connecting rails, broken glazing bars or weights that are not working properly can cause a lot of trouble. If these issues occur, it's time to consider a sash repair or replacement.

Refurbishment can be a more costly option than simply replacing the sash itself, but it can restore the look and function of your sash window to as good, if not better than the original condition. It involves lining the meeting rail and sash boxes with traditional putty, and then repairing any rot damage. Re-painting the frame of the timber is also included, as well as 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). It is also recommended to install brush pile weather strip to reduce rattling.

If the need for a new sash arises the frame 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 buildings, where any modifications to windows will require planning permission.

Compare the metal tabs of the new window with the old sash before installing it (see below). If they're different shapes, the new sash won't fit in the slots of the window frame.

It's important to decide whether to replace or repair a damaged window, as each choice will require a different level and level of expertise. For instance the case of a sash windows that has a large chunk of glass missing then replacing it is the best choice. But, if the glass is damaged in a tiny section or a sill has begun rotting then a repair will be the better option.

Replacement

While many homeowners are keen to keep their old windows in good condition, the deterioration of the windows can cause issues such as draughts, rattles, or even broken glass. This is why replacing sash windows is often the only solution to these problems. There are other methods to improve the performance of sash windows other than replacing them. This includes installing secondary glazing and draught-proofing.

It is crucial to assess the severity of the issue, since it might not be practical to replace an entire window. Foggy glass, for example, is usually caused by the sash and can be addressed without having to tear out the entire frame. A poor seal can also often be remedied by making a few minor adjustments instead of a costly full-frame tear-out and replacement.

Sash windows have a complex design with a lot of moving parts. It can be challenging to fix common problems such as broken panes, or snapped sash cables. Resolving these issues often requires dismantling the window frame, which isn't something the majority of homeowners would like to tackle on their own. Because of this, many homeowners choose to work with a professional.

A specialist can help restore windows made of sash to their original splendor, or even bring them up to modern energy standards. This may include reconditioning the frames and fitting secondary glass to stop heat from escaping through the window. It is also possible to add a brush-pile strip to reduce drafts and stop the window from squealing.

To begin a repair take out the window stops (the moldings that are in front of the lower sash). Then, loosen the staff bead and take off the lower sash. Take off the cords or chains on both sides. Then, remove the sash weights and the bottom of the cavity and take them off. Keep the hardware in a safe position. Use a heat gun to soften old, hardened filler or putty. Scrape it off with a putty blade. Reassemble the window, reattach the hardware and lubricate the pulley axles using silicone or Teflon spray. Install the parting beads again and then reinstall the upper sash.

Repair

The choice of replacing or repairing a sash window is a crucial one for homeowners. Modern replacements offer many advantages, but the original features in an older home can add authenticity and value. They are also cheaper to repair than replacing. Inspecting them regularly can help reduce the energy cost. Sash windows can be susceptible to rattles and drafts. This could result in more expensive energy bills and can damage the frame and sash.

Sash windows are notoriously difficult to open and close as the traditional sliding mechanism may become displaced from its track, or even draughty. Repairing a sash window involves extensive dismantling of the window frame, so it's best left to professionals. With the right tools and skills it is possible to repair an old sash window yourself. Adam shows Jess the basics:

Remove any security fittings in front of the lower window sash. Then, remove the staff bead. Then, take out the sash at the bottom. Remove the chains and cords from both sides, and tie them in a way that they can't be pulled back by the attached weights. It's now time to take out the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that supports the sash) and then loosen any paint-encrusted hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder that is concealed in a cavity, and held by a cord. To stop the sash falling into the void pierce it with a nail and sacrifice the weight.

Once the sashes are free, clean out the jamb and meet rails, remove the glazing cords and sash bars, and strip any paint from the sash stops with a utility knife. After the sashes have been put returned to their original positions, you can attach the stops using nails that are not too large to risk cutting the balancing weight.

To reassemble the sash put the top sash into its track first, and then the lower sash. Make sure that the sash stops and the frame are aligned properly. If needed, reconnect any parting beads. Reattach the sash chains or cords and attach the sash pulleys.
