Composite Doors vs Timber Doors
Written by Cornwall Composite DoorsReviewed by Cornwall Composite Doors installersLast updated July 20267 minute read
Short answer
Composite doors need far less maintenance than timber, resist Cornwall's damp weather better, and typically offer stronger security through multi-point locking on a rigid core. Timber doors can look more traditional and are repairable, but they need regular painting or staining and are more prone to swelling and warping.
Solid timber doors have a classic look many homeowners love, but they come with upkeep that composite doors avoid. This guide compares the two honestly, without dismissing timber's genuine appeal.
Maintenance requirements
Timber doors need regular repainting or re-staining, usually every few years, to protect the wood from moisture. Left untreated, timber can swell, crack or rot, particularly in exposed coastal locations. Composite doors need little more than an occasional wipe down and, in some cases, resealing to keep them looking good.
Weather performance in Cornwall
Cornwall's combination of salt air, driving rain and damp winters is tough on timber, which can absorb moisture and expand, making doors stick or seals fail. Composite doors' GRP skin is essentially waterproof, so they don't suffer the same swelling or rot issues over time.

Security
Modern timber doors can be fitted with good multi-point locks, but the timber itself can degrade around the lock and hinges if not properly maintained, weakening the fixing points over years. Composite doors' consistent core material means the fixing points stay solid for the life of the door.
Appearance and character
Solid timber has a genuine grain and warmth that some homeowners prefer, especially on period or listed-adjacent properties. Composite doors use moulded woodgrain finishes that convincingly mimic timber but won't have quite the same natural variation, though most people can't tell the difference from a normal viewing distance.
Cost over time
Timber doors can be cheaper to buy initially but cost more over their lifetime once you factor in repainting, refinishing and occasional repairs. Composite doors cost more upfront, typically £1,395–£2,795 fitted, but the lower ongoing maintenance often makes them better value over 10-20 years.
Repairability
Timber doors can usually be sanded, patched or repainted if damaged, which is a genuine advantage for older or characterful doors. Composite doors are generally more resistant to damage in the first place, but a badly damaged panel typically needs replacing rather than repairing.
Frequently asked questions
Do composite doors look as good as timber?
Quality composite doors use deep-moulded woodgrain finishes that closely resemble timber grain and texture, and most people won't spot the difference from the street. They don't have quite the natural variation of real wood, but the gap is small in practice.
How often do timber doors need repainting?
Depending on exposure, timber doors typically need repainting or restaining every 2-5 years to keep the protective coating intact. Doors on exposed, coastal or south-facing elevations tend to need attention more often.
Are timber doors more eco-friendly?
Timber is a natural, renewable material, which appeals to some buyers, though sourcing and finish matter. Composite doors last longer with less maintenance, which reduces waste and repainting chemicals over the door's lifetime — it's a genuine trade-off rather than a clear winner either way.
Can I get a composite door that looks like a specific timber style?
Yes, most composite ranges include panel designs modelled on traditional timber styles, such as cottage or Victorian panel layouts, so you can get a similar look without the maintenance.
