A composite door loses colour when sunlight and heat gradually break down the pigments in its outer skin. Dark shades facing south or west fade first, and cheaper doors with weaker coatings fade faster. A modern, UV-stabilised skin changes only slowly, and a pale colour hides what change does occur.
Which composite doors fade fastest?
Dark colours absorb the most heat and UV, so black, navy and anthracite doors in direct sun show change soonest. White and cream finishes are the least likely to look different over time.
How can you reduce fading on a composite door?
- Pick a lighter shade for a sun-facing entrance
- Choose a door with a UV-stabilised skin from a known maker
- Wash with warm soapy water, never abrasive cleaners
- Fit a porch or canopy where possible
Does the guarantee cover colour fade?
Colour stability is commonly included in manufacturer guarantees, but terms differ. Ask for the written wording and avoid painting or sanding the skin, as that can end the cover.
