The Complete Cornwall Homeowner's Guide to Choosing a Composite Door
Written by Cornwall Composite DoorsReviewed by Cornwall Composite Doors installersLast updated July 20268 minute read
Short answer
Choosing a composite door in Cornwall means matching the door's specification to your property's weather exposure, its architectural style, and your budget. Expect £1,395–£2,795 supply-and-fit, a 10-year written guarantee, and a coastal upgrade spec for exposed sites near Penwith, the Lizard or the north coast.
Cornwall's geography means there's no single right composite door for every home in the county. This guide pulls together the key decisions — exposure, style, colour, security and cost — so you can approach a quote with a clear idea of what you actually need.
Step 1: Assess your exposure
Where your property sits matters more in Cornwall than almost anywhere else in the country. Homes in Penwith, the Lizard or the open north coast between Bude and Perranporth need a genuinely different specification to sheltered inland towns like Bodmin or Launceston.
- High exposure: Penwith, the Lizard, north coast (Bude to Newquay)
- Moderate exposure: south-coast creeks, harbour towns
- Lower exposure: inland towns like Bodmin, Launceston, Liskeard
Step 2: Match the style to your property
Granite cottages and Victorian terraces generally suit heritage cottage-style panels in colours like Chartwell Green or Cream. Newer estates and post-war rendered homes suit contemporary flush designs in Anthracite Grey, Black or White. Look at what genuinely suits the building, not just current trends.

Step 3: Check conservation area rules
Parts of Truro, Falmouth, Fowey and several other Cornish towns and villages fall within conservation areas, which can restrict colour, style or glazing on street-facing doors. It's worth a quick check with Cornwall Council's planning team before ordering if you're unsure.
Step 4: Understand security ratings
A PAS24-rated multi-point locking system should be standard on any composite door you're considering, coastal or not. It's increasingly expected by insurers and gives genuine protection over a standard hook-lock design.
Step 5: Budget realistically
Supply-and-fit composite doors in Cornwall typically run £1,395–£2,795, depending on style, glazing, colour and any coastal specification upgrades. A written 10-year guarantee should be included as standard, not an optional extra.
Step 6: Choose an installer who understands Cornwall
An installer who surveys for exposure, understands Cornwall Council's conservation area patterns, and can talk through marine-grade fixings without upselling everyone the same spec will get you a better long-term result than a generic national supplier.
Frequently asked questions
How much does a composite door cost in Cornwall?
Supply-and-fit typically costs between £1,395 and £2,795, depending on the style, glazing and colour chosen, and whether a coastal specification upgrade is needed. We provide a written quote after survey so there are no surprises.
Do I need a different door if I live inland?
Generally you can use a standard composite specification if you're well inland, such as Bodmin or Launceston, without the marine-grade fixings and drainage detailing needed on exposed coastal sites. We'll confirm this at survey.
How long does installation take?
A single composite door installation typically takes half a day to a full day, including removal of the old door, fitting the new frame and door, and adjusting for a weathertight seal. We'll confirm timing when booking.
What guarantee comes with a composite door in Cornwall?
We provide a written 10-year guarantee on every composite door we install, regardless of location within Cornwall or the specification chosen. This covers manufacturing faults in the door itself when installed professionally.
Which brands do you install?
We install Endurance, Solidor, Hallmark, DoorCo and Distinction composite doors, giving a wide range of styles, colours and price points to suit different Cornish property types and budgets.
