Installing a new sash runner or spring bronze may be required when a gap is preventing windows from opening and shutting easily.

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 minimize the rattling.

If a replacement sash required it can be constructed using the same design to match your existing frame. This will preserve the style and character of your property. This is particularly important for listed properties where any changes to windows will require planning permission.

Repairing a sash windows requires extensive removal of the window frame and is best left to the professionals.

Getting the window to come apart begins by removing any security fittings on the front of the lower sash. Then, take off the staff bead. Then, take out the bottom sash. Remove the cords and chains from both sides, and knot them so that they cannot be pulled back by the attached weights. It's now time to take out the upper sash. Unscrew the sash stops (a thin vertical strip of wood that holds the sash) and then loosen any painted-covered hardware. Unscrew the sash to reveal the balancing weight that is a massive lead or iron cylinder enclosed inside a hidden compartment and anchored by a rope. To stop the sash from falling into the void, you must pierce it using a nail, and then sacrifice the weight.

After the sashes are removed, clean the jambs and the rails that meet. Remove the glazing bars and the cords for the sash. Then, using a utility blade take off any paint that is on the sash stop. When the sashes are returned to their original positions, you can attach the stops using nails that are small enough to avoid cutting the weight that is balancing.

To reassemble the sash place the top sash onto its track first, then the lower sash. Make sure that the sash stops and the frame are aligned properly. If needed, reconnect any parting beads. Reattach the sash chains or cords and attach the sash pulleys.
