Installing new sash runner or spring bronze might be required when a gap is preventing the windows from closing and opening effortlessly. These are strips of bronze that are stapled or nailed onto the edges of the lower sash to prevent sideways rattle. They are available from DIY stores. Tubular vinyl weather-stripping is another option, but it is prone to tear, and can affect the appearance of a window.

When a window is damaged it is essential to decide between replacement or repair, because each kind of work will require a different level of expertise and price.

Finally, remove the sash weights and the bottom of the weight cavity and remove them. Keep the hardware in a safe position. Soften any old filler or hardened putty using a heat gun, and scrape it off with the help of a putty knife.

Remove any security fittings in front of the lower window sash. Next, remove the staff bead, then take the sash off the bottom. Remove the chains and cords from both sides, and knot them in such a way that they won't be pulled back by the weights. The next step is to take out the upper sash. Take out the sash stops and a thin wood strip that holds the sash. Also, remove any hardware that has been painted. The sash can be pulled back to reveal the balancing weight, which is a large iron cylinder or lead that is enclosed in a hidden cavity and held by rope. To prevent the sash falling into the void pierce it using a nail, 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 from the sash stop. Reattach the stops once the sashes have been put back in place. Use nails that are small enough not 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 in the correct alignment with the frame, timber and then reconnect the parting beads if needed. Reattach the sash cords or chains and then install the sash pulleys.
