Bay window installation across Cardiff
If your Cardiff home has a Victorian or Edwardian bay frontage, replacing it properly is a bigger job than a standard window. As the capital of Wales and a former coal-export port, Cardiff has gone through decades of significant regeneration around the bay, and bay windows are a big part of what gives those streets their character. Cathays and Pontcanna carry conservation status covering much of the city’s Victorian terraced housing, and a bay window is usually the most visible feature on the whole street elevation, so getting the style right matters.

Frequently asked questions
Why do bay windows cost more than a standard window in Cardiff? A bay involves three or more frames plus a roof or canopy over the top, and often some structural work to the wall below - all of which adds labour and materials compared with a single flat window.
Do I need planning permission for a new bay window in Cardiff? Usually not for a like-for-like replacement, but cathays and Pontcanna carry conservation status covering much of the city’s Victorian terraced housing, so it’s worth checking if you’re changing the shape or size of the existing bay.
How long does a bay window installation take? Most single bay window jobs in Cardiff take one to two days, depending on whether the roof over the bay also needs attention.
