Sash Windows Repair and Replacement

Sash windows older than 20 years can have various issues such as rattles and draughts. They may also be poorly insulated. A little care can often bring them back to a top level of performance.

First, knock off the paint seal from the window stop using a utility knife. Remove the staff bead, pull out the upper sash and remove any cords or chains. Store upvc window repairs in a container with an identification label.

Sealing

Sash windows can look stunning in old buildings, however they do need maintenance and are susceptible to problems like cracked putty, wet rot, and drafts. It is possible to decrease energy loss and increase the efficiency of sash windows by replacing the windows, repairing or sealing them.

Draughts are mainly caused by gaps between the sash and the frame. They can also lead to rattles and reduce sound-proofing. Various methods can be used to stop air leaks from the sash window, such as sealing beads, specialty products, and secondary glazing.

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

If a gap is hindering windows from opening and closing smoothly, it may be necessary to install new sash runners or spring bronze. These bronze strips are attached by staples or nails to the sash's lower edges to prevent the rattling of the sides. They are available at DIY stores. Tubular vinyl weatherstripping can also be used, however it is more likely to tear and may alter the look of your window.

It is essential to determine the size of the window opening prior to installing a an alternative sash runner. It is best to measure from the top of the sash up to the horizontal centerline of the rail that connects it and from the bottom of the sash to the sill. These measurements can be incorporated into the new runners, which will ensure a good fitting and better operation of the window.

In older buildings the gap between frame and sash is typically larger around the leading edge. It is possible to draught-proof it using a strip of V-strip which is self-adhesive. However it is crucial to take this into consideration when measuring and cutting the material.

The strip should be cut at the height of the sash and with an inch extra on each side to allow for movement. The strip should be cut square and positioned in a way that the ends are matched to the angle of the window sill. Use stainless steel screws as brass will rust. Also, make sure to use the highest quality polyurethane or silicone glue.

Refurbishment

The sash is an attractive, historical feature of many homes. However, despite their beauty these windows are prone to a variety of problems. Draughts, rattling, sticking or leaking are typical issues. Frames that are rotting and rails that connect them, as well as broken glazing bars, defective frames, or rotten weights can cause issues. When these problems occur it's time to consider repairs or replacements to your sash.

Refurbishment can be a more costly alternative than replacing the sash itself, but it can improve the appearance and functionality of your sash window to as good, if not superior to its original state. Refurbishment involves lining both the meeting rail and the sash box with traditional putty and fixing any damage caused by rot. It also includes re-painting the frame with timber and reglazing 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). Finally, it's recommended to put in brush pile weather strips in order to minimize rattling and improve insulation.


If a new sash is needed It can be made using the same design to match the frame you have. This will help preserve the traditional style of your property. This is especially important for buildings that are listed, as any changes to the windows require planning permission.

Before putting the new window on before installing it, make sure you compare its metal tabs to the tabs on the old sash (see below). If they're different sizes, the new sash will not fit into the slots of the window frame.

It's important to decide whether to replace or repair windows that are damaged, as each choice will require a different level and amount of expertise. For instance when a sash window has a large piece of glass missing then replacing it is the best option. But, if the glass is damaged in one small section or a sill has begun decaying, a repair may be more appropriate.

Replacement

Many homeowners wish to keep their old sash window in good condition, however deterioration will eventually cause problems like draughts or rattles. Broken glass is also a possibility to occur. These issues typically lead to a replacement as the only sensible solution. There are other methods to improve the performance of sash windows rather than replacing them. They can be improved by the installation of secondary glazing and draught-proofing.

Consider the extent of the problem. It might not be necessary or even suitable to replace the window. A glass that is foggy, for example, is usually caused by the sash and can be fixed without tearing out the entire frame. A leaky seal can be fixed by a few easy fixes rather than an expensive 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 remedy some common problems, like snapped sash cords or broken panes. Resolving these issues often requires removal of the window frame which isn't something that the majority of homeowners would like to tackle themselves. Many homeowners decide to hire a specialist for these reasons.

Specialists can restore sash window frames back to their original splendor or update them to meet modern energy standards. This may include reconditioning frames and fitting secondary glazing to stop heat loss through the window. It may also be beneficial to add a brush pile strip, to stop the rattling and decrease drafts.

To begin a repair project start by removing the window stops (the moldings on the front of the lower sash). Then, loosen the staff and pull out the lower window sash. Take the chains and cords from both sides. Then, remove the sash weights and the bottom of the cavity and remove them. Keep the hardware in a secure location. Use a heat gun to soften old, hardened filler or putty. Scrape it off with a putty blade. Reassemble the window, attach the hardware and lubricate pulley axles by using silicone or Teflon spray. Reinstall the parting beads and then reinstall the upper sash.

Repair

The choice of replacing or repairing windows with sash is an important one for the homeowner. Although modern replacements can provide numerous benefits, 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 lower the energy cost. Sash windows are susceptible to rattles and drafts. This can lead to higher energy bills and even damage to the frame and the sash.

Sash windows are notoriously difficult to open and close and the standard sliding mechanism may become displaced from its track or become draughty. It is best to leave the repair of window with sash to a specialist because they require extensive dismantling. But, with the right tools and know-how it's possible to fix old windows with sash yourself. Adam shows Jess the basics:

Remove any security fittings just in front of the lower window sash. Then, you can remove the staff bead. Then, remove the sash at the bottom. Then, take the chains or cords on both sides, and tie the ends to stop them from being pulled back into the frame by the weights attached to them. It's now time to remove the upper sash. Remove the sash stops and a thin wood strip that holds the sash. Also, remove any hardware that has been painted. The sash should be pulled back to reveal the weight. It is a heavy iron or lead cylinder, which is tucked away in a cavity, and held by an elastic cord. To prevent the sash from falling into the void, hit it with an hammer and then sacrifice the weight.

After the sashes are removed, clean the jambs and the rails that meet. Remove the glazing bars and cords of the sash. Then using a utility knife, remove any paint from the sash stop. After the sashes have been put returned to their original positions, you can attach the stops using nails that are small enough to prevent puncturing the balancing weight.

To reassemble the sash, place the top sash onto its track first, and then the lower sash. Make sure the sash stoppers are properly aligned with the frame, and then reconnect the parting beads if needed. Reattach the sash chains or cords and attach the sash pulleys.
