What Cornwall Composite Doors offers
We're a Cornwall-based composite door specialist. That's it. We don't chase you into conservatories, roofline or new windows on the same visit — we're here to fit you a great composite door and stand behind it for a decade.
Every door is manufactured by Endurance, Hallmark or Solidor and finished in one of 20 Endurance colours (or a bespoke RAL). PAS24-rated hardware and a 3-star anti-snap cylinder come as standard, and every install is backed by a written 10-year installation guarantee.
Surveys are free, quotes are itemised, and there's no high-pressure sales visit at the end of the process. If you're comparing us with Duchy Windows & Conservatories, we'd encourage you to get both quotes, ask both companies the questions above, and decide from there.
