Black sliding doors across West Sussex
The right door depends on the opening, the room and the way you use the garden. Here is how black sliding doors tend to work out in practice:
Got a small, north-facing back room in West Sussex? A dual colour frame keeps the black outside while a paler inner face stops the room feeling boxed in.
Want black frames on your West Sussex home but worried about upkeep? The textured sandtex finish is a sensible middle ground, since it hides marks far better than smooth black.
- A fine-textured sandtex finish has a slightly gritty surface that disguises fingerprints, light scratches and water marks better than a smooth black coating.
- A black frame recedes against the view, so even a door with a standard-width interlock can look slimmer and more minimal than the same profile in a pale colour.
- Thermally broken aluminium systems are designed to cope with the extra expansion that comes from dark frames heating up in strong sun.

Daylight and glass in West Sussex
Because West Sussex sees long summer days (about 16 h 32 min) and short winter ones (about 7 h 55 min), the elevation your door faces makes a real difference. With the midday sun at about 16° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

Approvals in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Questions about black sliding doors in West Sussex
Do I need building approval for black sliding doors in West Sussex?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
What is the difference between RAL 9005 and RAL 9004?
RAL 9005 is jet black, the deepest standard black, while RAL 9004 is signal black, which is very slightly lighter and softer. Side by side, 9005 looks more intense and 9004 can appear marginally warmer. On a door frame the difference is subtle, so most people decide by looking at both samples against their own brick or render.
How much do black aluminium sliding doors cost?
On our aluminium doors black is a standard colour, so a single-colour black door is normally priced the same as white. The guide price for a 2.4 m two-panel door is £4,295–£5,295, and for a 3.6 m three-panel door £5,595–£6,895, fitted, inc VAT at standard 2.1 m height. Dual colour or special textures can add to the price.
What is a sandtex finish?
Sandtex is a common trade name for a fine-textured powder-coat finish with a slightly sandy feel. It is popular on black frames because the texture breaks up reflections and disguises fingerprints, small scratches and water marks that would stand out on smooth black. It is applied and cured the same way as other powder coatings.
