Sash Windows Repair and Replacement


Older sash windows suffer from a range of issues including draughts rattles, and poor insulation. A little attention can often bring them back to their original performance.

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

Sealing

Sash windows are gorgeous in older structures, but they require care. They can be affected by issues such as wet-rot, cracked putty and draughts. Repair, sealing, or replacement of the windows in sash is a great way to reduce these problems and improve energy efficiency.

The gaps between the sash and frame are the primary cause of draughts. They can also trigger noise and rattling, which can reduce soundproofing. Sealing beads, special products, and secondary glazing can be used to limit the air leakage inside a Sash.

A common issue is a gap between the top of the sash and the jamb frame, or the bottom of the sash and the sill. This can cause moisture to leak in, rotting wood, and mold growth. Seal the gap with silicone, polyurethane, or foam sealant.

If a gap in the window is preventing the windows from opening and closing without a hitch, it might be necessary to put in new spring bronze or sash runners. These are a type of bronze that are stapled or nailed onto the edges of the lower sash in order to prevent sideways rattle. They are available from DIY stores. Weatherstripping made of tubular vinyl can also be used, however it is prone to tear and may alter the look of your window.

When installing replacement sash runners, it is important to measure the entire width of the window opening. It is best to measure from the top of sash up to the horizontal centerline on the rail of the meeting and from the bottom of sash down 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 there is a greater gap between the sash and frame at the leading edge. It can be draught proofed with a strip of self-adhesive Vstrip, however it is important to consider this when cutting and measuring the material.

The strip should be cut at the top of the sash and with an inch added on each side to allow for movement. It should be squarely trimmed and positioned in accordance with the angle of the sill. Use stainless steel screws as brass will get rusty. Also, make sure you use a high quality silicone or polyurethane glue.

Refurbishment

The sash is a beautiful historic feature in many homes. They are beautiful but they can also be susceptible to problems. Rattling, draughts, sticking or leaks are all common problems. The rotting of frames and connecting rails, broken glazing bars, or damaged weights could add to the inconvenience. When these issues arise, it's time for an sash repair or replacement.

Refurbishment is a more expensive alternative than replacing the sash itself but it can improve the appearance and functionality of your sash window to as good, if not better than its original state. It involves lining the meeting rail and sash boxes with traditional putty and fixing any rot damage. Re-painting the frame of the timber is also included, as is re-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 put in brush pile weather strip to reduce rattling.

If a new sash is required the frame can be constructed from like-for-like designs to match the frame of the previous one and preserve the style of your home's historic design. This is especially crucial for listed buildings, where any modifications to windows require planning permission.

Before you put the new window on, it's best to compare its metal tabs to those on the old sash (see below). If the tabs are different shapes, the new sash will not fit correctly into the window frame slots.

If a window has been damaged, it is essential to decide between repair or replacement because each kind of work will require a different degree of expertise and cost. If a large part of the glass in a sash is missing, replacing it is the better option. But in the event that the glass has been damaged in one small section or a sill is rotting then a repair will be more appropriate.

Replacement

Many homeowners would like to keep their old sash window in good condition, however it is inevitable that deterioration will cause problems like draughts or rattles. Broken glass is also a possibility to occur. This is why it's often the only solution to these issues. But there are ways to improve the sash windows, beyond simply replacing them, such as installing draught proofing as well as secondary glazing.

It's important to consider the severity of a problem, as it may not be feasible to replace a complete window. For instance, a fogging glass issue typically occurs in the sash itself and is typically a solution without tearing out the entire frame. It is often possible to fix a weak seal by making a few easy fixes, rather than ripping out the entire frame and replacing it.

Sash windows have a complex design with many moving parts. This is why it can be tricky to solve common issues like sash cords that are snapped or broken panes. Many homeowners do not want to remove the window frame in order to fix these problems. Because of this, many opt to hire a specialist.

A specialist can assist in restoring windows with sash back to their original glory or even bring them up to modern energy standards. This may include reconditioning frames and fitting secondary glazing, to avoid heat loss through the window. It is also possible to add a brush-pile strip to reduce drafts and stop the window from rattling.

To begin a repair take out the window stops (the moldings that are in front of the lower sash). Then, loosen the staff and pull the lower window sash. Remove the cords and chains from both sides. Finally, disconnect the sash weights from the bottom of the weight cavity and take them off. Keep the hardware in a safe place. Soften any old filler or hardened putty using a heat gun, and scrape it away using a knife for putty. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray. Reinstall the parting bead, and install the upper sash.

Repair

The choice of replacing or repairing the sash window is a crucial one for homeowners. Modern replacements are beneficial in many ways, but the original features in an older home can add character and value. They are also cheaper to repair than replacing. Maintaining them in good condition can also lower the cost of energy. Sash windows can be prone to rattles and drafts. This could result in higher energy bills and even damage to the frame and sash.

Sash windows can be a challenge to open and close. The mechanism for sliding could be slack or even draughty. It is recommended to leave the repair of sash windows to professionals since it requires a lot of removal. However, with the right tools and knowledge, it is possible to repair old windows with sash yourself. Adam shows Jess how to start:

Getting the window to come apart starts with the removal of any security fittings in front of the lower sash. Then, take off window repairs . Then, remove the sash at the bottom. Then, take the chains or cords on both sides and tie them to stop them from being pulled back into the frame by the weights attached to them. It's time to take off the upper sash. The sash stops must be removed, 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 hidden in a cavity, and held by a cord. To stop the sash falling into the void make a hole in it using an hammer and then sacrifice the weight.

Once the sashes are free, clean out the jamb and meet rails. remove the glazing bars and sash cords and scrape off any paint off the sash stops with an utility knife. Reattach the stops when the sashes have been reinstalled. Use nails that are not large enough to damage the balancing weight.

To reassemble the sash, put the top sash into its track first, then the lower sash. Verify that the sash stoppers and the frame are aligned correctly. If necessary, reattach any parting beads. Reattach the sash chains or cords and then install the sash pulleys.
