Black sliding doors across Lincolnshire
A few practical points decide whether black sliding doors suit a particular room and opening:
Where the rest of a Lincolnshire home has white windows, a black sliding door on the rear extension can work well, provided the extension reads as a separate, modern addition.
Have white render on your Lincolnshire property? Black frames give the sharpest contrast against it, but view jet black and signal black samples on the wall before choosing.
- A fine-textured sandtex finish has a slightly gritty surface that disguises fingerprints, light scratches and water marks better than a smooth black coating.
- With a dual colour frame you can keep black outside for the architecture and choose a lighter colour inside, so a small room does not feel enclosed by dark framing.
- Black frames can be paired with black handles, interlock caps and track covers so the whole door, including its hardware, reads as a single dark outline.

Daylight and glass in Lincolnshire
Sun angles matter for big glazed doors. Around Lincolnshire, midday sun reaches about 60° in summer and drops to about 13° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Approvals in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Questions about black sliding doors in Lincolnshire
Is the price different in Lincolnshire?
No. Guide prices for black sliding doors are the same across mainland Britain, including Lincolnshire. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
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.
