Anthracite grey sliding doors across Greater London
Before you settle on a door type, it helps to know what anthracite grey sliding doors do well and what to check before you order.
If your Greater London home is listed, is a flat, or is covered by an Article 4 direction, check with the council before changing the colour of a door that faces the street.
If your Greater London home is close to the sea, washing powder-coated frames more often removes salt deposits and helps the anthracite finish keep its sheen.
- A blue-grey tone frames the garden view without the hard contrast of black, so the door reads as part of the elevation rather than a dark outline.
- Because the colour is part of the frame, not a film over it, small marks on aluminium can usually be touched in with a matched repair kit rather than replacing the section.
- Powder coating is cured in an oven into a continuous film, giving a hard-wearing finish that does not need repainting, only occasional washing with mild soapy water.

Questions about anthracite grey sliding doors in Greater London
Is the price different in Greater London?
No. Guide prices for anthracite grey sliding doors are the same across mainland Britain, including Greater London. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
How do I clean anthracite sliding doors?
Wash anthracite frames with warm water, a little mild detergent and a soft cloth, then rinse and dry. Avoid abrasive pads, solvents and strong household cleaners, which can dull or mark the powder coating. Vacuum grit out of the track before wiping it, because dirt in the track wears rollers and makes the door feel stiff to slide.
How does powder coating work?
Powder coating is a dry finishing process that bonds coloured polyester powder to the aluminium with heat. The profiles are cleaned and pretreated, the powder is sprayed on with an electrostatic charge so it clings evenly, and the frame is baked until the powder melts into a smooth, hard film. It resists chipping and fading far better than wet paint.
What is the difference between textured and smooth anthracite?
Textured anthracite has a fine grain you can feel, while smooth anthracite has a flat satin or matt surface. Textured finishes hide fingerprints, light scratches and water marks better and suit doors that get heavy use. Smooth finishes look sleeker and more minimal but show dust and marks more readily. Both are durable powder coatings applied the same way.
