If bay windows are a feature of your house, all the preceding details apply, but in addition the jambs, the uprights framing the window, will usually be of stone, although some are of brick. Brick jambs should never be painted, but as with the stone sills and lintels, stone jambs may have been painted.

Some terrace houses may have single-storey bay windows. These are often of timber construction on a brick plinth. The timber should be regularly painted.

The roofs of bay windows will be of slate or lead; a small number have flat leaded roofs. A few have decorative fish scale slate roofs. Where these survive, they should be cherished! Bay windows had their own moulded wood cornices or eaves, and cast iron guttering.

Bay window roofs are sometimes decorated with cast terracotta or metal finials.

Most streets have houses with bay windows
