Sealing

Sash windows are beautiful in old buildings, however they do need maintenance and can be subject to issues such as cracks in putty, wet rot and draughts. It is possible to minimize energy loss and increase the efficiency of windows with sash by replacing them the windows, repairing or sealing them.

Draughts are usually caused by gaps between the sash and the frame. They can also lead to rattling and reduced sound-proofing. Various methods can be used to limit air leaks within a sash window, including sealing beads, specialty products and secondary glazing.

A common issue is a gap between the top of the sash and the jamb frame or between the bottom of sill and the sash. This can cause moisture leaking in, rotting of the wood and the growth of mould. Seal the gap with silicone, polyurethane or foam sealant.

If a gap is hindering windows from closing and opening easily, it could be necessary to install new spring bronze or sash runners. These are a type of bronze that are stapled or nailed onto the edges of the lower sash to prevent sideways rattle, and they can be purchased from DIY stores. Weatherstripping made of tubular vinyl can also be used, however it tends to rip and can alter the appearance of your window.

It is important to determine the size of the window opening prior to installing a an alternative sash runner. It is best to take measurements from the top of sash up to the horizontal centerline of the rail that connects them and from the bottom sash down to the sill. These measurements can be transferred to new runners which will ensure the best fit and function of the window.

In older structures the gap between the frames and sash is typically greater around the leading edge. It is possible to draught proof by using a self-adhesive V-strip, but it is important to consider this when cutting and measuring 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 squarely trimmed and positioned in accordance with the angle of the sill. Use stainless steel screws since brass may rust. Also, make sure you use high-quality polyurethane or silicone glue.

It involves lining the meeting rail and sash box using traditional putty, and then repairing any damage caused by rot. It also involves 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). In addition, it is recommended to fit brush pile weather strips in order to minimize rattling and improve insulation.

If a replacement sash is required it can be constructed using the same design to match your existing frame. This will help preserve the traditional style of your house. This is particularly crucial for listed buildings, where any changes to the windows require planning permission.

Before you put the new window on before installing it, make sure you check the metal tabs against those on the old sash (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 repair or replacement, since each kind of repair will involve a different level of expertise and price. For instance the case of a sash windows that has a significant piece of glass that is missing, then replacing it is the best option.

For instance, a foggy glass issue typically occurs within the sash itself and is usually able to be resolved without tearing out the entire frame. A leaky seal can often be remedied by making a few minor adjustments rather than an expensive full-frame tear-out and replacement.

Sash windows are extremely complex in design and feature lots of moving parts. This is why it can be tricky to remedy some common problems, like snapped sash cords or broken panes.

It is also possible to add a brush-pile strip to reduce drafts and prevent the window from shaking.

Then take the sashweights out of the bottom cavity of the weight. Place the hardware in a secure place. Soften any old filler or hardened putty by using a hot gun. Then scrape it away with a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys using Teflon or silicone spray. Install the parting beads and then reinstall the upper sash.

Modern replacements offer many advantages however, the original features in an older home can provide authenticity and value. They are also cheaper to repair than replacing.

Repairing a sash window involves extensive dismantling of the frame of the window and is best left to the professionals. However, with the right tools and knowledge it is possible to fix old windows with sash yourself. Adam shows Jess how to get started:

Remove any security fittings behind the lower window sash. Then, you can remove the staff bead. Then, remove the bottom sash. Then, remove the chains or cords on both sides and knot the ends to stop them from being pulled back into the frame by the weights attached to them. It's time to take off the upper sash. Remove the sash stops (a thin vertical strip of wood that is used to hold the sash) and then loosen any painted-covered hardware. Pull the sash back to reveal the weight. It is a heavy iron or lead cylinder that is concealed inside a cavity and supported by cords. To stop the sash from falling into the void, you must pierce it with a nail and then sacrifice the weight.

After the sashes have been removed clean the jamb and rails that meet, remove the glazing bars and sash cords, and scrape off any paint off the sash stops with the help of a utility knife. Reattach the stops after the sashes have been put back in place. Use nails that are small enough not to puncture the balancing weight.

Reassemble the sash by placing the upper sash first on its track, then the lower sash. Make sure the sash stops are properly aligned with the frame, and reattach the beads that separate if required. Finally, reattach the sash chains or cords and then re-attach the axles for the sash pulleys.
