Older sash windows be prone to a variety of issues including draughts rattles, and inadequate insulation. With a little effort, they can be restored 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 take out any chains or cords. Store the hardware in a bag that has an identification label.
Sealing
Sash windows can look stunning in old buildings but they require maintenance and could be susceptible to issues like wet rot, cracked putty, and drafts. It is possible to minimize energy loss and improve the efficiency of sash windows by replacing or repairing them, or sealing them.
The gaps between the sash and frame are the main source of drafts. They can also cause noise reduction and rattle. Sealing beads, special products and secondary glazing can all be used to minimize the air leakage inside the shutter.
A common issue is a gap between the top of the sash and the jamb frame, or between the bottom of the sash and the sill. This can lead to moisture leaking in the wood, rotting and growth of mould. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.
Installing a new sash runner, or spring bronze might be required in the event that a gap blocks the windows from opening and shutting effortlessly. These bronze strips are stapled or nailed to the lower sash edges in order to stop the rattling of the sides. They can be bought at DIY stores. Weatherstripping made of tubular vinyl can also be used, but it is prone to tear and may alter the look of your window.
It is important to measure the entire window opening prior to installing the new sash runners. It is recommended to take measurements from the top of the sash up to the horizontal centerline of the meeting rail and from the bottom sash down to the sill. These measurements can be incorporated into the new runners, which will help ensure a perfect fit and better operation of the window.
In older buildings the gap between sash and frame is usually greater around the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However, it is important to take this into consideration when measuring and cutting material.
A strip must be cut to the width of the sash, with an extra inch each side to allow for movement. It should be squarely trimmed and positioned to match the angle of the sill. It is also important to make use of stainless steel screws since brass can rust and a high-quality polyurethane or silicone adhesive.
Refurbishment
The Sash window is a beautiful, historic feature of many homes. They are beautiful however they are susceptible to issues. Draughts, rattling, sticking or leaking are common issues. Rotting frames and meeting rails as and broken glazing bars, defective weights or rotten frames are all causes of problems. If you are experiencing any of these problems it's time to replace or repair your sash.
Refurbishment may be more expensive than replacing the sash, but can bring back the appearance and function to the same standard in its original condition. It involves lining the joining rail and sash box with traditional putty, and then repairing any damage caused by rot. Re-painting of the timber frame is also included, as well as 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's also recommended to install brush pile weather strip to minimize the 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 the style of your home's historic design. This is especially important for listed properties where any changes made to the windows will require planning permission.
Compare the metal tabs on the new window with the old sash prior to installing it (see below). If the tabs are different shapes, the new sash will not fit properly into the window frame slots.
When a window is damaged it is essential to decide between replacement or repair, since each kind of repair will involve a different level of expertise and expense. If a significant portion of the glass in a sash is missing, replacing it would be an option. If the glass is damaged in a tiny area or a sill has begun to decay and needs to be repaired, then a repair will be more appropriate.
Replacement
Although many homeowners want to keep their old sash windows in good working order, deterioration can eventually cause issues such as draughts, rattles, or even broken glass. These issues usually lead to a replacement as the only sensible solution. However, there are ways to improve sash windows that go beyond replacing them, including installing draught proofing and secondary glazing.
It is important to determine the extent of a issue, since it might not be appropriate or even feasible to replace the entire window. A foggy glass problem, for example is typically 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 are surprisingly complicated in their design and come with lots of moving parts. It can be challenging to fix some common problems such as broken panes, or snapped sash cables. The solution to these issues typically involves dismantling the window frame, which isn't something that most homeowners want to tackle on their own. Many homeowners opt to engage a professional for these reasons.
A specialist can assist in restoring sash windows to their original splendor, or even bring them up to the latest energy standards. This could include reconditioning frames and fitting secondary glass to stop heat from getting out of the window. It may also be beneficial to install an extra strip of brush pile to stop rattling, and reduce drafts.
To begin a repair, remove the window stops. (The moldings are in front of the lower glass). Then, loosen the staff and remove the lower window sash. Remove the chains or cords on both sides. Then, remove the sash weights from the bottom of the weight cavity and take them off. Keep the hardware in a secure 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. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray. Install the parting beads and reinstall the upper part of the sash.
Repair
It is important for homeowners to make a choice on whether to replace or repair their sash windows. 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 rather than replace. Maintaining them in good condition can help reduce the energy cost. Sash windows are prone to rattles, drafts and condensation, and these problems can result in increased costs for energy and damage to the frame and sash.
Sash windows can be a challenge to open or close. The mechanism that slides can become sloppy or even draughty. Repairing a sash windows requires extensive dismantling of the frame of the window and is best left to a professional. However, with the right tools and know-how it's possible to repair old sash windows yourself. Adam shows Jess how to get started:
Remove any security fittings that are behind the lower window sash. Then, remove the staff bead, then remove the bottom sash. Then, remove the cords or chains on both sides, and tie them to prevent them being pulled back into the frame by the weights attached to them. It's now time to take out the upper sash. Remove the sash stops (a thin vertical strip of wood that supports the sash) and remove any painted-covered hardware. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder that is concealed in a cavity, and held by a cord. To prevent the sash falling into the void pierce it using a nail, and then let the weight go.
After the sashes are removed clean the jambs as well as rails that connect them. Remove the glazing bars and cords of the sash. Then using a utility knife take off any paint from the sash stop. Reattach the stops once the sashes have been reinstalled. Use nails that are small enough not to damage the balancing weight.
Reassemble the sash by placing the upper sash first into its track, then the lower sash. Make sure the sash stops are in the correct alignment with the frame, and then reattach the parting beads if needed. Then, reconnect the sash chain or cords and re-attach the sash pulley axles.
