Sash windows are beautiful in old buildings, however they require regular maintenance and could be susceptible to issues like cracked putty, wet rot and draughts. Repair, sealing or replacement of the windows in sash is a great method to minimize these issues and improve the efficiency of energy.

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

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

Installing a new sash runner or spring bronze may be required when a gap is preventing the windows from opening and shutting easily. These are strips of bronze that are stapled or nailed onto the edges of the lower sash to prevent sideways rattle. They are available at DIY stores. Tubular vinyl weatherstripping can also be used, but it is prone to tear and can alter the appearance of your window.

It is recommended to measure from the top of the sash to the horizontal line of the rails that meet, and from the bottom of the sash down to the sill.

In older structures, there is a wider gap between the sash as well as the frame on the leading edge. It can be draught-proofed with a strip of self-adhesive V-strips, but it is crucial to account for this when measuring and cutting the material.

The strip should be cut at the top of the sash with an inch more on each side to allow movement. It should be trimmed squarely and placed to match the angle of the sill. It is also crucial to use stainless steel screws as brass can rust, and high-quality polyurethane or silicone adhesive.

Refurbishment

The sash is a stunning, historical feature of many homes. Yet despite their beauty, these windows are susceptible to a range of issues. Draughts, rattling or leaking are typical issues.

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).

It is crucial to determine whether to replace or repair windows that are damaged, as each choice will require a different degree and amount of knowledge.

Take off the chains or cords on both sides. Finally, remove the sash weights from the bottom of the cavity and remove them. Keep the hardware in a secure position. Soften any old filler, hardened putty, or filler using a heat gun, and scrape it off with the help of a putty knife. Reassemble the window. Reattach the hardware. Lubricate the pulleys using Teflon or silicone spray. Reinstall the parting bead, and reinstall upper sash.

Take out the sash stops, a thin vertical wood strip that holds the sash. Also, take off any paint-encrusted hardware. The sash can be pulled back to reveal the weight balancing, that is a massive lead or iron cylinder enclosed inside a hidden compartment and anchored by a rope. To prevent the sash from falling into the void, make a hole in it using an hammer and then sacrifice the weight.

After the sashes are removed, clean the jambs and rails that connect them. Remove the glazing bars and sash cords. Then employing a utility blade take off any paint that is on the sash stop. Once the sashes are back in place, you can reattach the stops using nails that are small enough to prevent puncturing the weight that is balancing.
