As clearer and larger glass sheets became available, sash windows began to replace hinged casements. They were made of plate glass, set in timber frames with rebates and secured with glazing sprigs, and then putty on both sides to ensure they were watertight. This type of glazing gradually replaced leaded lights.

The introduction of sashes resulted in the need for a larger variety of ironmongery with the basic fittings being brass pulleys as well as lead (and later cast iron) weights, sash stops shutter hinges and knobs as well as a range of fasteners that secured the sashes to their the right place.

The result was a much lighter appearance, and windows with a greater level of elegance than they had before.

The introduction of sash windows also required an entirely new range of ironmongery. Early pulleys were made from wood, later Victorian ones could be made of brass or a mixture of wood and lead, and there were various types of shutter hinges and knobs. These ironmongery pieces should be maintained and cleaned to appreciate their fine design.

The removal of sashes could also result in structural movement within the frame that causes the sash to move out of alignment and not closing properly. It is also possible for the sash be snagged or fixed in an open position and this can let water and draughts enter the property.

The damage to timber windows is often caused by water penetration. This can be avoided by regular repairs by thorough painting and eliminating the source of dampness. The paint can be removed to reveal the soft, rotting wood. Any timber that is rotting must be removed and the affected part carefully scarfed or pieced in using replacements made of the same kind of timber as those remaining. This method of repair increases the amount of fabric left, and is among the least invasive methods of treating timber-to-timber decay.
