Sealing

Sash windows look gorgeous in older buildings, but they require maintenance and can be subject to problems like wet rot, cracked putty, and drafts. It is possible to decrease energy loss and increase the efficiency of sash windows by replacing, repairing or sealing them.

The gaps between the sash and frame are the main source of draughts. They can also trigger noise reduction and rattling. There are a variety of methods to stop air leaks from a sash window, including sealing beads, specialty products, and secondary glazing.

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

Installing new sash runner or spring bronze may be required when a gap is preventing the windows from opening and shutting smoothly. These are strips of bronze that are stapled or nailed into the edges of the lower sash in order to prevent sideways rattle. They can be purchased from DIY stores. Tubular vinyl weather-stripping is an alternative option but it has a tendency to tear, and can make a difference to the appearance of a window.

When replacing sash runners It is crucial to measure the window opening. It is best to take measurements from the top of the sash up to the horizontal centerline of the meeting rail and from the bottom of sash down to the sill. These measurements can then be transferred to new runners, which will ensure an improved fit and 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 with a strip of self-adhesive V-strip, but it is essential to account for this when cutting and measuring the material.

A strip must be cut to the length of the sash, with an extra inch to allow for movement. The strip should be cut square and positioned so that the ends are aligned to the angle of the window sill. It is also important to use stainless steel screws, because brass is prone to rust, and the best 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 also be susceptible to issues. Common issues include rattling stuck or draughty windows. Frames that are rotting and meeting rails as and broken glazing bars, damaged frames or weights that are rotten are all causes of problems.

It involves re-lining the meeting rail and sash box with traditional putty, and then repairing any rot damage. Re-painting of the timber frame is also included, as well as re-glazing using 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's also recommended to install brush pile weather strip to prevent the noise of rattling.

If a window is damaged, it is essential to decide between replacement or repair, since each kind of repair will involve a different level of expertise and price.

The process of bringing the window apart starts with the removal of any security fittings on the front of the lower sash. Then, take off the staff bead. Then, remove the sash at the bottom. Remove the cords and Window Doctor chains from both sides, and tie 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 supports the sash) and loosen any painted-covered hardware. The sash can be pulled back to reveal the balancing weight which is a large iron cylinder or lead that is enclosed in a concealed cavity and anchored by a rope. To stop the sash from falling into the void pierce it with a nail and sacrifice the weight.

Once the sashes are free clean the jamb and rails that meet, remove the glazing bars and sash cords, and strip any paint off the sash stops using a utility knife. After the sashes have been put back in place, reattach the stops using nails that are not too large to risk cutting the balancing weight.
