Sash Windows Repair and Replacement

Older sash windows be plagued by a variety of problems including draughts, rattles and poor insulation. With a little effort they can be repaired to a higher level of performance.

First, remove the paint seal using an utility knife. Remove the staff bead, then pull out the upper sash and remove any cords or chains. The hardware should be stored in a container with a label.

Sealing

Sash windows are gorgeous in older structures, but they require maintenance. They are susceptible to problems like wet-rot cracked putty, and draughts. It is possible to minimize energy loss and improve the efficiency of sash windows by replacing the windows, repairing or sealing them.

Draughts are mainly caused by gaps between the sash and the frame. They can also cause rattles and reduce sound-proofing. Sealing beads, specialist products and secondary glazing can all be used to minimize the air leakage within a Sash.

A common issue is a gap that exists between the top of the sash and the jamb frame, or the bottom of the sash and the sill. This can lead to moisture leaking into the wood, rotting it and growth of mold. The gap can be sealed with silicone or polyurethane caulking or foam sealant.

If a gap is hindering windows from opening and closing smoothly, it may be necessary to replace spring bronze or sash runners. These are strips of bronze that are stapled or nailed onto the edges of the lower sash to prevent sideways rattle. They can be purchased from DIY stores. Tubular weatherstripping also can be used, but it tends to rip and can detract the appearance of your window.

When installing replacement runners for sash, it is important to take full measurements of the window opening. It is recommended to take measurements from the top of the sash up to the horizontal line on the rail of the meeting and from the bottom 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 structures the gap between sash and frame is usually greater around the leading edge. It can be draught-proofed by using strips of V-strip that is self-adhesive. However it is essential to consider this when measuring and cutting the material.

A strip should be cut to the length of the sash, with an extra inch to allow for movement. The strip should be cut square and positioned in a way that the ends are matched to the angle of the window sill. It is also crucial to use stainless steel screws because brass is prone to rust, and a high-quality silicone or polyurethane adhesive.

Refurbishment

The sash is a stunning historic feature in many homes. These windows are gorgeous however they are susceptible to issues. Draughts, rattling, sticking or leaks are all common problems. Frames that are rotting and rails that meet, as along with broken glazing bars, faulty frames, or rotten weights can cause issues. When these problems occur it's time to consider an sash repair or replacement.

Refurbishment is more expensive alternative than replacing the sash itself, however, it can bring back the appearance and function of your sash window as good if not superior to its original state. It involves lining the joining rail and sash box using traditional putty, and then repairing any damage caused by rot. 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). Finally, it's recommended to install brush pile weather strips to lessen rattle and increase insulation.

If you require a new sash 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 especially important for listed buildings where any changes to the windows will require planning permission.

Before you put the new window in place before installing it, make sure you compare its metal tabs to those on the sash that was previously used (see below). If they're different shapes and sizes, the new sash will not fit into the window frame slots.

It's important to decide whether to repair or replace a damaged window, as each choice will require a different level and amount of expertise. If a large portion of the glass in a sash is missing replacing it is an option. If the glass is damaged in a small area or a sill is beginning to rot and needs to be repaired, then a repair will be better.

Replacement

Many homeowners would like to keep their old sash window in good condition, however deterioration will eventually cause problems such as rattles or draughts. Broken glass can also occur. This is why replacing them is often the only option to solve these issues. But there are ways to improve the sash windows beyond just replacing them, including installing draughtproofing and secondary glazing.

It is crucial to assess the severity of the issue, since it might not be appropriate or even practical to replace an entire window. A glass that is foggy for instance is typically caused by the sash and can be addressed without having to tear out the entire frame. It is usually possible to fix a poor seal with a few simple fixes, rather than ripping out the entire frame and reinstalling it.

Sash windows are surprisingly complex in design and have many moving parts. It can be challenging to fix some common problems like cracked panes or snapped sash cables. Most homeowners don't want to disassemble the window frame in order to fix these problems. Many homeowners decide to hire a specialist for these reasons.

Specialists can restore sash window frames to their original splendor or update them to meet modern energy standards. This could include reconditioning the frames and installing secondary glazing, to avoid heat loss through the window. It may also be beneficial to install a brush pile strip, to stop rattling and reduce drafts.

To begin a repair project take out the window stops (the moldings that are in front of the lower sash).

Then, remove the sash weights and the bottom of the cavity and take them off. Keep the hardware in a safe place. Soften any old, hardened putty or filler with a heat gun and scrape it away using the help of a putty knife. Reassemble the window, reconnect the hardware and then lubricate the pulley axles using silicone or Teflon spray. Reinstall the parting bead, and install the upper sash.

Repair

It is essential for the homeowner to decide whether to replace or repair their sash windows. While modern replacements provide numerous benefits but the original features of a home that was built earlier provide character and value to the home and are usually cheaper to fix than replacing them. Keeping them in good condition will also help you save money on energy. Sash windows can be prone to drafts and rattles. This could 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 even draughty. It is recommended to leave the repair of sash windows to professionals, as it requires a lot of removal. However, with the right tools and knowledge it's possible to repair old sash windows yourself. Adam shows Jess how to get started:

Getting the window to come apart starts with the removal of any security fittings that are in front of the lower sash. Then, remove the staff bead. Finally, pull out the sash at the bottom. Remove the cords and chains from both sides, and knot them in a way that they can't be pulled back by the weights attached. It's time to remove the upper sash. Remove the sash stops and a thin 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 large iron or lead cylinder that is concealed inside a cavity and held by cords. To prevent the sash from falling into the void pierce it with an hammer and then sacrifice the weight.

After the sashes have been removed 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. When the sashes are returned to their original positions, you can attach the stops using nails that are not too large to risk damaging the balancing weight.

Reassemble the sash by placing the upper sash first on its track, then the lower sash. Make sure the sash stoppers are in the correct alignment with the frame, and then reconnect the beads that separate if required. Then, reconnect the sash chain or cords and re-attach the axles for the sash pulleys.
