Hinges and catches
Worn or damaged hinges and fittings can cause gaps to develop between the window frame and the face of the opening window, resulting in draughts.
● If hinges, latches, stays and bolts are stuck, ease with a little oil or WD-40.
● Contact a blacksmith or specialist metal window company for repairs or missing parts.
Traditional metal windows were rarely weatherstripped to keep out rain and draughts so it’s essential to minimise gaps between the frame and the opening casement or fanlight.
● Open the window and ensure surfaces are clean, dry and free from dust.
● Apply cling film around the edge of the opening section.
● With a sealant gun, run a thin silicone bead around the frame using either clear silicone or a matching colour.
● Squash the silicone to shape by closing the window onto it and allow the silicone to fully dry.
● Open the window and remove the cling film, which has acted as a bond-breaker.
● Trim back any excess silicone with a sharp knife.
● Or, where suitable, fix brush-seals or thin, soft rubber draught excluders to the opening edges.
● Consider secondary glazing, where a slimline pane of glazing is added to your windows.
