It's important to decide whether to replace or repair a damaged window, as each will require a different degree and level of knowledge.

While modern replacements provide many advantages however, the original features of an older home give authenticity and value to the property and are usually cheaper to repair than replacing them.

Sash windows are notoriously difficult to close and open and the standard sliding mechanism can become dislodged from its track, or even draughty. Repairing a sash window involves extensive removal of the window frame, so it's best left to a professional. But, with the right tools and knowledge, it is possible to fix old windows with sash yourself. Adam shows Jess how to start:
Getting the window to come apart begins by removing any security fittings in front of the lower sash. Then, take off the staff bead. Finally, pull out the sash at the bottom. Remove the chains and cords from both sides, and knot them in a way that they can't be pulled back by the weights attached. It's time to remove the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that holds the sash) and then loosen any paint-encrusted hardware. Pull the sash to reveal the balancing weight which is a large iron cylinder or lead that is enclosed inside a hidden compartment and held by rope. To prevent the sash falling into the void pierce it with a nail and then sacrifice the weight.
When the sashes are untied, clean out the jamb and meet rails. remove the glazing bars and sash cords and remove any paint from the sash stops using a utility knife. When the sashes are returned to their original positions, you can attach the stops using nails that are not too large to risk cutting the balancing weight.
Reassemble the sash by placing the upper sash first into its track, then the lower sash. Make sure the sash stops are aligned properly with the frame, and reattach the beads that separate if required. Finally, reattach the sash chain or cords and re-attach the sash pulley axles.
