Sash Windows Repair and Replacement
Older sash windows can be prone to a variety of issues including draughts rattles, and poor insulation. A little attention can often restore them to a top level of performance.
First, take off the paint seal using an utility knife. Remove the staff bead, pull out the upper sash, and remove any cords or chains. The hardware should be stored in a bag with the label.
Sealing
Sash windows are gorgeous in older buildings, but they require maintenance. They can be affected by problems like wet-rot cracked putty, and draughts. It is possible to reduce energy loss and increase the efficiency of windows with sash by replacing them or repairing them, or sealing them.
Draughts are mostly caused by gaps between the sash and frame. They can also trigger noise and rattling, which can reduce soundproofing. Various methods can be used to stop air leaks from the sash window, such as sealing beads, specialty products and secondary glazing.
A gap between the top or bottom of the sash and the jamb frame, is an issue that is common. This can lead to moisture leaking in, rotting wood and growth of mold. Seal the gap using silicone, polyurethane, or foam sealant.
If a gap in the window is preventing windows from opening and closing smoothly, it may be necessary to install new sash runners or spring bronze. These bronze strips are tied or stapled to the lower sash edges to stop the rattling of the sides. They can be purchased at DIY stores. Tubular vinyl weatherstripping can also be used, however it is more likely to tear and can alter the appearance of your window.
It is essential to determine the size of the window opening prior to installing a replacement sash runner. It is recommended to take measurements from the top of the sash to the horizontal centerline of the meeting rail and from the bottom of the sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a good fit and better operation of the window.
In older structures the gap between the frames and sash is typically 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 take this into account when measuring and cutting the material.
The strip should be cut to the height of the sash, with an inch extra on each side to allow movement. It should be trimmed squarely and placed to match the angle of the sill. It is also important to use stainless steel screws as brass can rust, and high-quality polyurethane or silicone adhesive.
Refurbishment
The windows with sash are a stunning and historic feature of many homes. They are beautiful, but they can be susceptible to issues. Common issues include rattling draughts or sticking. And rotting frames and meeting rails, broken glass bars or faulty weights can create a mess. If you are experiencing any of these problems it's time to replace or repair your sash.
Refurbishment is a more expensive alternative than replacing the sash itself, however, it can improve the appearance and functionality of your sash window to the same or better than its original state. It involves lining the meeting rail and sash box using traditional putty and repairing any damage caused by rot. It also involves painting the frame of timber 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). In addition, it is recommended to fit brush pile weather strips to reduce the rattling and increase insulation.
If a new sash is required it can be constructed using similar designs to the frame that was previously used and keep the style of your home's historic design. This is particularly crucial for listed buildings, where any changes to the windows will require planning permission.
Before you put the new window in place, 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 window frame slots.
If a window has been damaged, it's essential to choose between repair or replacement since each kind of repair will involve a different level of expertise and price. For instance when a sash window has a large chunk of glass missing, replacing it is the best choice. But, if the glass has been damaged in a small area or a sill is decaying, a repair may be the better option.
Replacement
Many homeowners want to keep their old sash window in good condition, however it is inevitable that deterioration will cause problems like rattles or draughts. Broken glass can also occur. These issues typically lead to a replacement as the only feasible solution. There are other ways to improve the performance of sash windows rather than replacing them. These include the installation of secondary glazing and draught-proofing.
It's important to consider the severity of a problem, as it may not be practical to replace an entire window. For instance, a fogging glass issue typically occurs in the sash itself and is usually able to be resolved without having to tear out the entire frame. A weak seal can be fixed by making a few minor adjustments instead of a costly full-frame tear-out and replacement.
Sash windows are surprisingly complex in design and feature many moving parts. This is why it can be tricky to solve common issues such as snapped sash cords or broken panes. Solving these issues usually requires dismantling the window frame, which isn't something the majority of homeowners would like to take on themselves. This is why many opt to hire a professional.
A professional can help restore windows with sash to their original splendor, or even bring them up to the latest energy standards. This could include reconditioning frames and fitting secondary glass to prevent heat from escaping through the window. It is also possible to put in a brush pile strip, to stop rattling, and reduce drafts.
To begin the repair, remove the window stops. (The moldings are located in front of the lower glass). Then you can loosen the staff, and remove the lower window sash. Remove the cords and chains from both sides. Finally, remove the sash weights from the bottom of the weight cavity and remove them. Keep the hardware in a safe location. Heat gun to soften old, hardened filler or putty. Scrape Resource off using a blade made of putty. Reassemble the window, reconnect the hardware and then lubricate the pulley axles using silicone or Teflon spray. Reinstall the parting beads and then reinstall the upper sash.
Repair
The choice of replacing or repairing the sash window is an important one for the homeowner. Although modern replacements can provide many advantages but the original features of a home that was built earlier provide authenticity and value to the property and are usually cheaper to repair than replacing them. Maintaining them in good shape can help lower 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 the sash.
Sash windows can be a challenge to open or close. The mechanism for sliding could be slack or draughty. Repairing a sash windows requires extensive dismantling of the window frame, so it's best left to professionals. With the right tools and skills it is possible for you to repair the old sash window yourself. Adam shows Jess the basics:
Remove any security fittings just in front of the lower window sash. Then, remove the staff bead, then pull out the bottom sash. Remove the chains and cords from both sides, and knot them in such a way that they won't be pulled back by the weights attached. It's now time to remove the upper sash. Unscrew the sash stops (a thin vertical strip of wood that is used to hold the sash) and then loosen any painted-covered hardware. Unscrew the sash to reveal the weight balancing, which is a large iron cylinder that is encased in a hidden cavity and anchored by a rope. To keep the sash from falling into the void, hit it with a nail and sacrifice the weight.
After the sashes have been removed, clean the jambs and the rails that meet. Remove the glazing bars and the cords for the sash. Then using a utility knife take off any paint that is on the sash stop. 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 weight that is balancing.
