New composite doors for Cardiff homes

Most of our composite doors jobs in Cardiff start with the same call: "old timber and rotten 90s uPVC front doors that leak heat, jam in winter and fail break-in standards". Around here that usually means a Edwardian and Victorian bay-fronted houses in Cathays and Roath where the original frames have given up. We work right across CF10 and CF11 and CF14 and CF23 and CF24 and CF5 — Cyncoed, Llanishen, Roath and the surrounding streets — typically arriving via A48. Old frame stripped on the day, new outer frame fitted plumb to the brick reveal, threshold sealed with EPDM and silicone.

FAQs — composite doors in Cardiff

Do you fit composite doors across all of Cardiff?+

What guarantee do I get when you fit composite doors in Cardiff?+

Can composite doors handle heritage-friendly frame profiles in conservation streets?+

Directly, yes — grp skins don't warp, fade only slowly under direct uv, and resist coastal salt better than aluminium-skin doors. That matters in Cardiff where heritage-friendly frame profiles in conservation streets is the single most common reason people call us.

Do you cover Penarth and Caerphilly as well?+

Yes — Penarth is roughly 4 miles from Cardiff, Caerphilly about 7. Same team, same prices, same guarantee.

Will composite doors suit the older Edwardian and Victorian bay-fronted houses in Cathays and Roath common around Cardiff?+

The 48mm slab clears most South Wales brick reveals without needing a packer; sidelights match Edwardian bay layouts. We've installed dozens in Cyncoed and Llanishen alone.

Solve heritage-friendly frame profiles in conservation streets for good

Our composite doors use GRP weatherproof skin to fix the root cause — not patch it.
