Sash Windows Repair and Replacement

Sash windows older than 20 years can have various issues, including draughts and rattles. They could also be poorly insulated. With a little care they can be restored to their original performance.

First, cut off the seal with a utility knife. Remove the staff bead, then pull out the upper sash, and remove any cords or chains. Store the hardware in a bag with the label.

Sealing

Sash windows are gorgeous in older structures, but they require regular maintenance. They can be affected by issues such as wet-rot, cracked putty, and draughts. Repair, sealing or replacement of the sash window is an effective method to minimize these issues and improve energy efficiency.

Draughts are usually caused by gaps between the sash and the frame. They can also cause noise reduction and rattling. Sealing beads, specialist products and secondary glazing can all be used to minimize the air leakage in the Sash.

A gap between the top or bottom of the sash and the jamb frame, is an issue that is frequent. This can lead to the leaking of moisture, rotting of the wood, and mould growth. Seal the gap using silicone, polyurethane, or foam sealant.

Installing new sash runner or spring bronze could be required if a gap prevents the windows from opening and shutting smoothly. These bronze strips are attached by staples or nails to the sash's lower edges to stop the rattling of the sides. They can be purchased at DIY stores. Tubular vinyl weatherstripping can also be used, but it is prone to tear and may alter the look of your window.

When installing replacement runners for sash, it is important to take full measurements of the window opening. It is best to take measurements from the top of sash up to the horizontal line on the rail that connects them and from the bottom of sash down to the sill. These measurements can be transferred to new runners which will ensure a better fit and operation of the window.

In older buildings, the gap between frame and sash is typically wider around the leading edge. It can be draught-proofed using strips of V-strip that is self-adhesive. However it is essential to consider this when measuring and cutting material.

The strip should be cut at the top of the sash, with an inch more on each side to allow for movement. It should be trimmed square and placed so that the ends are aligned to the angle of the window sill. It is also crucial to use stainless steel screws since brass can rust and high-quality silicone or polyurethane adhesive.

Refurbishment

The windows with sash are a stunning and historic feature of many homes. Yet despite their beauty, these windows are prone to a variety of problems. Rattling, draughts, sticking or leaking are typical issues. The rotting of frames and meeting rails, broken glass bars or faulty weights can cause a lot of trouble. When these problems occur it's time to consider an sash repair or replacement.

Refurbishment is more costly than replacing the sash but it will restore the appearance and function to the same standard as its original state. Refurbishment involves the lining of the meeting rail as well as the sash box with traditional putty, and then repairing any damage caused by decay. 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 fit brush pile weather strips in order to minimize rattle and increase insulation.

If a replacement sash is needed it can be constructed using the same style to match your existing frame. This will preserve the heritage style of your property. This is especially important for listed buildings where any changes to the windows require planning permission.

Before you put the new window in place, it's best to compare its metal tabs to those on the sash that was previously used (see below). If they are different shapes the new sash may not fit inside the window frame slots.

It is crucial to determine whether to replace or repair a damaged window, as each option will require a different level and level of knowledge. For example when a sash window has a large chunk of glass missing, replacement is the best choice.

A leaky seal can often be corrected with a few simple fixes rather than an expensive full-frame tear-out and replacement.

Unscrew the sash stops (a thin vertical strip of wood that holds the sash) and then loosen any painted-covered hardware. Pull the sash to reveal the balancing weight which is a large iron cylinder that is encased in a hidden cavity and held by a rope. To prevent the sash falling into the void pierce it using a nail, and sacrifice the weight.

When the sashes are untied Clean the jamb and meet rails, remove the glazing bars and sash cords, and scrape off any paint from the sash stops with an utility knife. Once the sashes are back in place, reattach the stops using nails that are small enough to prevent cutting the weight that is balancing.
