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 Zenith, we'd encourage you to get both quotes, ask both companies the questions above, and decide from there.
