Sash windows look stunning in older buildings, but they require maintenance. They are susceptible to issues such as wet-rot, cracked putty, and draughts. Repair, sealing or replacement of the windows in sash is a great way to reduce these problems and increase energy efficiency.

The gaps between sash and frame are the primary cause of draughts. They can also cause noise reduction and rattling. Different methods can be employed to limit air leaks within windows with sash, including sealing beads, specialist products, and secondary glazing.

A gap between the top or bottom of the sash and the jamb frame, is an issue that is common. This can lead to moisture leaking in the wood, rotting and the growth of mould. The gap can be filled with silicone or polyurethane caulking or foam sealant.

Installing new sash runner or spring bronze may be required when a gap is preventing the windows from opening and shutting easily. upvc window repair are strips of bronze that are stapled or nailed to the edges of the lower sash to stop sideways rattle.

It's important to decide whether to replace or repair windows that are damaged, as each option will require a different degree and cost of knowledge. If a significant portion of the glass in a sash is missing replacing it is the better option. But when the glass is damaged in a tiny section or a sill has been damaged, a repair would be more appropriate.

Replacement

Adam shows Jess the basics:

Getting the window to come apart begins by removing any security fittings on the front of the lower sash. Next, remove the staff bead and pull out the bottom sash. Then, take the chains or cords on both sides, and tie them to stop them from being pulled back into the frame by the weights that are attached. It's now time to remove the upper sash. Remove the sash stops (a thin vertical strip of wood that is used to hold the sash) and remove any paint-encrusted hardware. Pull the sash to reveal the balancing weight that is a massive iron cylinder that is encased in a concealed cavity and held by a rope. To prevent the sash from falling into the void hit it with 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, using a utility blade take off any paint that is on the sash stop. Reattach the stops when the sashes have been put back in place. Use nails that are not large enough to puncture the balancing weight.
