Sealing Sash windows look gorgeous in old buildings but they require regular maintenance and can be subject to issues like cracked putty, wet rot, and draughts. It is possible to minimize energy loss and increase the efficiency of sash windows by replacing, repairing or sealing them. Draughts are usually caused by gaps between the sash and the frame.

A gap between the top and bottom of the sash and the jamb frame, is an issue that is common. This can lead to moisture leaking in and rotting of the wood, and mould growth. Seal the gaps with silicone, polyurethane or foam sealant. Installing a new sash runner, or spring bronze could be necessary in the event that a gap blocks windows from opening and shutting effortlessly. These are strips of bronze that are stapled or nailed to the edges of the lower sash in order to prevent sideways rattle. They are available at DIY stores. Tubular weather-stripping made of vinyl is a different option, but it is prone to tear and make a difference to the appearance of a window. It is important to determine the size of the window opening prior to installing a new sash runners.

It is possible to draught proof by a self-adhesive Vstrip, however it is crucial to account for this when cutting and measuring the material. A piece of material should be cut to the length of the sash, with an additional inch each side to allow to allow movement.

If they are different shapes, the new sash will not fit inside the slots of the window frame. It's important to decide whether to replace or repair windows that are damaged, as each will require a different degree and cost of expertise.

Then, loosen the staff bead, then pull out the lower sash. Remove the cords and chains from both sides. Then remove the sashweights from the bottom cavity of the weight. Keep the hardware in a secure place. Soften any old, hardened putty or filler using a heat gun, and scrape it away using a knife for putty.

Then, pull out the chains or cords on both sides and knot them to prevent them being pulled back into the frame by the weights attached to them. The next step is to take out the upper sash. Unscrew the sash stops (a thin vertical strip of wood that supports the sash) and then loosen any painted-covered hardware. Unscrew the sash to reveal the balancing weight which is a heavy iron cylinder or lead that is enclosed in a concealed cavity and held by a rope. To stop the sash falling into the void hit it with nails and remove the weight. Once the sashes are free clean the jamb and rails that meet, remove the glazing bars and sash cords, and scrape off any paint off the sash stops using the help of a utility knife. Reattach the stops once the sashes are reinstalled. Use nails that are not large enough to puncture the weight of the balancing. To reassemble the sash, place the top sash onto its track first, and then the lower sash. Make sure that the sash stops are aligned properly with the frame, and then reconnect the beads for parting if necessary. Then, reconnect the sash chain or cords and re-attach the axles of the sash pulleys.
