Sealing

Sash windows are gorgeous in older buildings, but they require care. They are susceptible to issues such as wet-rot, cracked putty, and draughts. Sealing, replacement or repair of the sash window replacement is an effective method to minimize these issues and improve the efficiency of energy.

Draughts are mostly caused by gaps between the sash and frame. They can also trigger noise reduction and rattle. Various methods can be used to limit air leaks within windows with sash, including sealing beads, special 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 cause moisture to leak into the wood, rotting it and the growth of mold. The gap can be filled with caulking made of polyurethane or silicone or foam sealant.

Installing a new sash runner or spring bronze could be necessary in the event that a gap blocks windows from closing and opening easily. These are strips of bronze that are stapled or nailed onto the edges of the lower sash in order to prevent sideways rattle, and they can be purchased at DIY stores. Tubular weather-stripping made of vinyl is a different option however it can tear, and can affect the appearance of a window.

When replacing sash runners It is crucial to measure the window opening. 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 good fit and a better performance of the window.

In older structures the gap between the frames and sash is typically wider around the leading edge. It can be draught proofed by a self-adhesive Vstrip, however it is crucial to consider this when cutting and measuring the material.

A strip must be cut to the width of the sash, with an additional inch each side to allow to allow for movement. The strip should be cut 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 the best quality polyurethane or silicone adhesive.

Refurbishment

The Sash window doctor (more about Envtox Snu Ac) is a beautiful, historic feature of many homes. These windows are beautiful but they can also be prone to problems. Draughts, rattling, sticking or leaks are all common problems. The rotted frames and the rails that meet, as well as broken glazing bars, damaged frames or weights that are rotten can cause issues. If you encounter any of these issues, it is time to replace or repair your sash.

Refurbishment is more costly than replacing the sash but can restore the appearance and functionality to the same level as its original state. Refurbishment involves lining both the meeting rail and the sash box with traditional putty and fixing any damage caused by the 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). It is also recommended to install brush pile weather strip to minimize the rattling.

If you require a new sash it can be constructed from similar designs to the frame of the previous one and preserve your property's heritage style. This is particularly important for listed buildings where any modifications to windows need planning permission.

Before you put the new window in before installing it, make sure you examine its metal tabs with the tabs on the old sash (see below). If they're different shapes, the new sash won't fit properly into the window frame slots.

It's important to decide whether to repair or replace a damaged window, as each option will require a different degree and level of knowledge. For instance when a sash window has a significant piece of glass that is missing, then a replacement will be the best choice. But when the glass is damaged in a small area or a sill has been rotting then a repair will be the better option.

Replacement

While many homeowners are keen to keep their old windows in good condition, the deterioration of the windows can result in problems like draughts, rattles, or even broken glass. This is why it's often the only option to solve these issues. But there are ways to improve sash windows beyond just replacing them, including installing draughtproofing and secondary glazing.

Take note of the severity of the problem. It might not be necessary or appropriate to replace the window. Foggy glass, for example, is usually caused by the sash, and can be resolved without tearing out the entire frame. It is typically possible to fix a weak seal by making a few easy fixes, rather than tearing out the entire frame and reinstalling it.

Sash windows feature a complicated design with a lot of moving parts. It can be a challenge to fix common issues such as broken panes, or sash cables that have snapped. The solution to these issues typically involves removal of the window frame which isn't something that most homeowners would want to tackle on their own. For these reasons, many choose to work with a specialist.

Specialists can restore sash window frames to their original splendor or make them more up-to-date with modern energy standards. This may include reconditioning the frames and fitting secondary glass to block heat from escaping through the window. It is also possible to add a brush pile strip to stop rattling and reduce drafts.

To begin a repair, take off the window stops. (The moldings are on the side of the lower glass). Next, remove the staff bead and remove the lower sash. Remove the cords and chains from both sides. Finally, remove the sashweights from the bottom cavity of the weight. Keep the hardware in a secure location. The heat gun will soften old, hardened filler or putty. Scrape it off using a putty blade. Reassemble the window, reconnect the hardware and then lubricate the pulley axles with silicone or Teflon spray. Reinstall the parting bead, and reinstall upper sash.

Repair

It is essential for homeowners to decide whether to replace or repair their sash windows. Modern replacements offer many advantages, but the original features in an older home can provide authenticity and value. They are also cheaper to repair rather than replace. Keeping them in good condition can also save energy costs. Sash windows can be susceptible to drafts and rattles. This can result in higher energy bills and damage the frame and the sash.

Sash windows are notoriously difficult to open and close and the standard sliding mechanism can be displaced from its track or become draughty. It's best to leave the repair of a window sash to a professional, as they require extensive dismantling. With the right tools and skills, it is possible for you to repair old sash window yourself. Adam shows Jess how to begin:

The process of bringing the window apart starts by removing any security fittings on the front of the lower sash. Then, take off the staff bead. Then, remove the bottom sash. Then, remove the cords or chains on both sides and knot the ends to stop them from being pulled back into the frame by the attached weights. Now it's time to take out the upper sash. Remove the sash stops (a thin vertical strip of wood that holds the sash) and remove any painted-covered hardware. The sash can be pulled back to reveal the balancing weight, which is a heavy iron cylinder or lead that is enclosed in a concealed cavity and secured by rope. To prevent the sash falling into the void, you must pierce it with a nail and sacrifice the weight.

Once the sashes are free clean the jamb and rails that meet, remove the glazing cords and sash bars, and scrape off any paint off the sash stops with the help of a utility knife. After the sashes have been put back in place, you can reattach the stops using nails that are small enough to avoid cutting the balancing weight.

To reassemble the sash, place the top sash onto its track first, then the lower sash. Make sure that the sash stops are in the correct alignment with the frame, and then reattach the beads for parting if necessary. Reattach the sash chains or cords and then install the sash pulleys.
