Bay and bow window replacements for Cardiff’s signature Edwardian bay-fronts
Cardiff’s terraced streets are famous for the bay-fronted Edwardian terrace — a square or shallow-splayed two-storey bay is the single most repeated house feature in the city, from Cathays through Roath and Canton down to Grangetown. Replacing one is more involved than a flush window: the corner posts, cill projection and small bay roof all need attention, and in Pontcanna or Roath Park the glazing bar pattern must be replicated exactly. Legacy Windows is a quote comparison service that matches you with installers who quote the complete bay package.

Frequently asked questions
Can I replace a Cathays bay-front without touching the roof? Usually yes — most Cardiff two-storey bays run the full height with the upper bay windows sitting on the lower ones, and a small tiled bay roof at the top. If the bay carries roof load (rare on standard terraces), a structural engineer sign-off is needed before removing the old frames.
Typical Cardiff bay price? A standard three-panel splayed UPVC bay comes in around £1,410 to £2,600 fitted for a single-storey bay, or £2,400 to £3,340 for a full two-storey bay-front. Timber or timber-effect for a Pontcanna conservation frontage sits at the upper end.
Are Edwardian glazing bar patterns available? Yes. All Cardiff panel installers offer applied Georgian bars, Edwardian upper-light patterns and integrated stained-glass replication — matching the original detail is usually essential in Pontcanna, Roath Park and Cathays Park.
