The gaps between sash frame are the primary source of drafts. They can also cause noise and rattling, which can reduce soundproofing. Sealing window repair , specialist products and secondary glazing can all be used to reduce the air leakage in the sash.

A common problem is a gap between the top of the sash and the jamb frame, or between the bottom of sash and the sill. This can cause water leaking into the wood the wood, rotting, and mould growth. The gap can be closed with caulking made of polyurethane or silicone or foam sealant.

If a gap is preventing the windows from opening and closing without a hitch, it might be necessary to put in new sash runners or spring bronze.

Tubular vinyl weatherstripping can also be used, but it tends to rip and can detract the appearance of your window.

When installing replacement runners for sash 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 of the meeting rail and from the bottom sash down to the sill.

In older structures the gap between the sash and frame is usually wider around the leading edge. It can be draught-proofed by a self-adhesive V-strip, but it is essential to account for this when cutting and measuring the material.

A strip should be cut to the width of the sash, with an additional inch to allow movement. It should be trimmed squarely and placed in accordance with the angle of the sill. Use stainless steel screws since brass will rust. Also, make sure you use a high quality polyurethane or silicone glue.

Refurbishment

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 also recommended to put in brush pile weather strips to reduce the rattling and increase insulation.

If a new sash is required, it can be made from like-for-like designs to match the frame of the previous one and preserve the style of your home's historic design. This is particularly important for buildings that are listed, as any changes to the windows require planning permission.

Compare the metal tabs on the new window to the old sash prior to installing it (see below). If they're different shapes, the new sash will not fit correctly into the slots of the window frame.

It is crucial to determine whether to repair or replace the damaged window, since each choice will require a different degree and cost of expertise. For example, if a sash window has a significant piece of glass missing then a replacement will be the best choice. If the glass is damaged in a tiny area or a sill has begun to decay or rotting, then a repair could be more appropriate.

Replacement

For instance, a foggy glass issue typically occurs within the sash itself and is typically a solution without ripping out the whole frame.

It is also possible to add an edge strip for brush-piles to cut down on drafts and prevent the window from shaking.

To begin a repair, take off the window stops. (The moldings that are located in front of the lower glass). Next, loosen the staff bead, then remove the lower sash. Take off the chains or cords that are on both sides. Then, remove the sash weights from bottom of the weight cavity and take them off. Keep the hardware in a secure location. Soften any old filler or hardened putty with a heat gun and scrape it off with a knife for putty. Reassemble the window, reconnect the hardware and lubricate pulley axles by using silicone or Teflon spray. Install the parting beads and reinstall the upper sash.

Remove any security fittings that are just in front of the lower window sash. Then, you can remove the staff bead. Then, take out the sash at the bottom. Take the chains and cords from both sides, and tie them in a way that they can't be pulled back by the attached weights. It's now time to remove the upper sash. Unscrew the sash stops (a thin vertical strip of wood that is used to hold the sash) and loosen any painted-covered hardware. The sash can be pulled back to reveal the balancing weight that is a massive iron cylinder or lead that is enclosed in a concealed cavity and anchored by a rope. To prevent the sash falling into the void, you must pierce it using a nail, and then let the weight go.

After the sashes have been removed, clean the jambs and rails that connect them. Remove the glazing bars as well as the cords for the sash. Then, using a utility blade take off any paint that is on the sash stop. When the sashes are back in place, reattach the stops using nails that are small enough to avoid damaging the balancing weight.

To reassemble the sash place the top sash on its track first, and then the lower sash. Make sure the sash stoppers are properly aligned with the frame, and then reconnect the beads that separate if required. Reattach the sash cords or chains and then install the sash pulleys.
