Sealing

Sash windows are gorgeous in older structures, but they require regular maintenance. They can be affected by problems like wet-rot cracked putty and draughts. It is possible to reduce energy loss and increase the efficiency of sash windows by replacing, repairing or sealing them.

The gaps between sash and frame are the primary cause of draughts. They can also trigger noise reduction and rattling. Sealing beads, specialty products, and secondary glazing can be used to limit the air leakage in the sash.

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

If a gap in the window is preventing the windows from opening and closing without a hitch, it might be necessary to replace sash runners or spring bronze. These strips of bronze are stapled or nailed to the lower sash edges to prevent the rattling of the sides. They can be purchased at DIY stores. Tubular vinyl weatherstripping can also be used, however it is more likely to tear and can detract the appearance of your window.

When replacing sash runners it is essential to measure the entire width of the window opening. It is best to measure from the top of the sash up to the horizontal centerline on the rail that connects them and from the bottom sash down to the sill. These measurements can then be transferred to new runners which will ensure a better fit and operation of the window repairs near me.

In older buildings the gap between the frame and sash is typically wider around the leading edge. It can be draught-proofed with a strip of self-adhesive Vstrip, however it is important to take this into consideration when cutting and measuring the material.

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 install brush pile weather strips to lessen rattle and increase insulation.

The sash stops must be removed which is a thin vertical strip of wood that holds the sash. Also, take off any hardware that has been painted. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder that is hidden in a cavity and is held by an elastic cord. To prevent the sash falling into the void, pierce it with a nail and sacrifice the weight.

After the sashes have been removed clean the jambs and rails that connect them. Remove the glazing bars and cords of the sash. Then using a utility knife, remove any paint from the sash stop.
