Older sash windows may be prone to a variety of issues, including draughts rattles, and inadequate insulation. With a little care, they can be restored to a higher level of performance.
First, cut off the seal with a utility knife. Remove the staff bead, pull out the upper sash, and take out any chains or cords. Store the hardware in a container with an identification label.
Sealing
Sash windows look gorgeous in older buildings, but they do need maintenance and are susceptible to issues such as cracked putty, wet rot, and draughts. It is possible to decrease energy loss and increase the efficiency of sash windows by replacing the windows, repairing upvc door or sealing them.
Draughts are mostly caused by gaps between the sash and the frame. They can also trigger rattling and reduced sound-proofing. Different methods can be employed to reduce air leaks in a sash window, including sealing beads, specialty products and secondary glazing.
A common problem is a gap between the top of the sash and the jamb frame or between the bottom of the sill and the sash. This can cause moisture leaking in the wood, rotting and growth of mould. Seal the gap with silicone, polyurethane or foam sealant.
Installing new sash runner or spring bronze may be necessary in the event that a gap blocks windows from closing and opening effortlessly. These strips of bronze are tied or stapled to the lower sash edges in order to stop sideways rattling. They can be bought at DIY stores. Weatherstripping made of tubular vinyl can also be used, but it is more likely to tear and may alter the look of your window.
It is important to determine the size of the window opening prior to installing the new sash runners. It is recommended to measure from the top of the sash up to the horizontal line on the meeting rail and from the bottom sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a proper fitting and better operation of the window.
In older buildings there is a greater gap between the sash and frame around the leading edge. It can be draught-proofed by a self-adhesive V-strip, but it is essential to consider this when measuring and cutting the material.
A strip must be cut to the width of the sash, and with an additional inch each side to allow to allow for movement. It should be trimmed square and placed in a way that the ends are matched to the angle of the window sill. It is also important to use stainless steel screws, as brass can rust, and high-quality silicone or polyurethane adhesive.
Refurbishment
The Sash window is a beautiful and historic feature of many homes. Yet despite their beauty, these windows are susceptible to a variety of problems. The most frequent issues are rattling, draughts or sticking. Frames that are rotting and rails that connect them, as and broken glazing bars, damaged frames or weights that are rotten are all causes of problems. If you are experiencing any of these problems it's time to replace or repair your sash.
Refurbishment is more costly than replacing the sash, however, it can bring back the appearance and function to the same standard that it was in its original form. Refurbishment involves lining both the meeting rail and the sash box using traditional putty, and repairing any damage caused by decay. It also involves painting the timber frame 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 put in brush pile weather strips in order to minimize the rattling and increase insulation.
If a replacement sash needed, it can be made using the same style to match the frame you have. This will maintain the style and character of your house. This is particularly important for listed buildings where any changes to the windows require planning permission.
Compare the metal tabs of the new window to the old sash before installing it (see below). If they are different shapes the new sash may not fit inside the slots of the window frame.
If a window has been damaged, it's essential to choose between replacement or repair, because each type of work will involve a different level of expertise and cost. For example the case of a sash windows that has a large piece of glass missing, replacing it is the best option. If the glass is only damaged in a tiny area or a sill is beginning to rot or rotting, then a repair could be more appropriate.
Replacement
Although many homeowners want to keep their old windows in good order, deterioration can eventually cause problems such as rattles, draughts or even broken glass. This is why it's often the only solution to these problems. There are other ways to improve the performance of sash windows than simply replacing them. These include installing secondary double glazing windows repairs and draught-proofing.
Consider the extent of the issue. It might not be necessary or even appropriate to replace windows. For example, a foggy glass issue usually occurs within the sash and is usually able to be resolved without having to tear out the entire frame. It is often possible to fix a poor seal with a few simple fixes, rather than ripping out the entire frame and replacing it.
Sash windows are surprisingly complex in design and feature lots of moving parts. This is why it can be tricky to remedy some common problems like sash cords that are snapped or broken panes. Resolving these issues often requires dismantling the window frame, which isn't a job most homeowners would want to tackle on their own. Many homeowners decide to hire a specialist for these reasons.
Specialists can restore sash window frames back to their original splendor or make them more up-to-date with the latest energy standards. This can include reconditioning the frames and installing secondary glazing to stop heat loss through the window. It is also possible to install an extra strip of brush pile to stop rattling, and reduce drafts.
To begin a repair, remove the window stops (the moldings on the front of the lower sash). Next, loosen the staff bead and take off the lower sash. Remove the chains and cords from both sides. Finally, remove the sash weights from the bottom of the cavity and remove them. Keep the hardware in a safe location. Soften any old filler, hardened putty, or filler by using a hot gun. Then scrape it away using a putty knife. 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 decision to repair or replace the sash window is a major one for homeowners. While modern replacements provide numerous benefits however, the original features of an older home give authenticity and value to the property and are often cheaper to fix than replacing them. Maintaining them in good condition will also help you save money on energy. Sash windows can be prone to rattles and drafts. This could result in more expensive energy bills and can damage the frame and sash.
Sash windows can be a challenge to open and close. The mechanism for sliding could be slack or draughty. It is best to leave the repair of window with sash to a specialist because they require extensive dismantling. With the right tools and skills it's possible to repair an the old sash window yourself. Adam shows Jess the basics:
Remove any security fittings that are in front of the lower window sash. Then, take off the staff bead. Then, remove the sash at the bottom. Take the chains and cords from both sides, and tie them so that they cannot be pulled back by the weights attached. The next step is to remove the upper sash. The sash stops must be removed which is a thin vertical strip of wood that is used to hold the sash. Also, remove any paint-encrusted hardware. Reverse the sash to reveal the weight. It is a large iron or lead cylinder that is concealed inside a cavity and secured by an elastic cord. To prevent the sash from falling into the void pierce it with a nail and sacrifice the weight.
After the sashes are removed, clean the jambs and meet rails. Remove the double glazing repair bars and cords for the sash. Then, using a utility blade, remove any paint from the sash stop. When the sashes are back in place, you can reattach the stops using nails that are small enough to avoid cutting the weight that is balancing.
To reassemble the sash put the top sash into its track first, and then the lower sash. Check that the sash stops and the frame are aligned properly. If necessary, reattach any beads used for parting. Finally, reattach the sash cords or chains and re-install the axles of the sash pulleys.
