Bay window replacement in Portsmouth

Bays in Portsmouth are common on the Southsea, Fratton and North End Victorian terraces. Many were built with the box frames carrying load, so a steel or reinforced lintel is usually needed - and on an exposed island elevation the lead flashing has to be robust against driving rain off the Solent.

Why Portsmouth homeowners choose us

  • Structural survey of the bay before any frame is ordered
  • Matched frame widths so the bay keeps its proportions
  • Steel or reinforced lintel fitted where the opening needs it
  • Robust lead flashing and apron detail for weather-facing island bays
  • Scaled elevation drawings to approve before manufacture

Frequently asked questions

Does my Portsmouth Victorian bay need a steel? Almost certainly if it is pre-1914. A survey confirms it before any frame is ordered. Budget £600 to £1,200 for the work.

How much does a bay window cost in Portsmouth? Typically £1,236 to £3,296 for the glazing using the local 1.03x factor, plus the structural work if needed.

Does the exposed position affect the flashing? Yes - a bay facing the weather off the Solent needs a heavier lead flashing and apron detail to keep out driving rain.
