Aluminium sliding doors in Greenwich: what to know
These are the points a surveyor will go through with you when you choose aluminium sliding doors for a home in Greenwich:
For a south- or west-facing garden in Greenwich, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
Whether you live in Greenwich or elsewhere in Greater London, a lawn or patio sitting just below floor level can still take a low threshold, provided an outside drainage channel or a fall away from the door is planned.
- Because the panels slide rather than swing, nothing opens into the room or across the patio, leaving space for a dining table, sofa or planters right up to the glass.
- Aluminium is stiff enough to carry wide panels without bowing, which keeps the number of vertical frames low even across openings of four, five or six metres.
- Brush and gasket weather seals along every meeting edge, together with drainage slots in the outer track, carry rainwater away instead of letting it collect against the panels.
How much sun will a door in Greenwich get?
At the latitude of Greenwich, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 50 min against 16 h 38 min in midsummer. A south-facing aluminium sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.
What should you budget for aluminium sliding doors in Greenwich?
These are guide prices for fitted doors at a standard height, including VAT. They run from an entry-level system to a premium one at the same size; the survey confirms which suits your opening.

| 3.6 m | 3 panels | £5,595–£6,895 |

Survey, manufacture and fitting around Greenwich
A surveyor visits your Greenwich home to measure the structural opening, check levels and the lintel, and talk through glass and finish. Once you confirm the written specification, the door is made to measure — typically 4–6 weeks from survey sign-off — and fitting usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors. We also cover Blackheath (2 km south-east) and Lewisham (2 km south).
Rules for aluminium sliding doors 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.
Which options matter for aluminium sliding doors?
- Handles and locks. Slim pull handles or lever handles in matching or contrasting finishes, with an enhanced security locking pack available.
- Dual colour. A different colour inside and outside, so the exterior can match your windows while the interior suits the room.
- Panel configuration. Two, three or four panels, with the sliding panel on the left, right or both sides to suit how you use the room.
Questions about aluminium sliding doors in Greenwich
Can you match other doors and windows in my Greenwich home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
Are aluminium sliding doors warm enough for a UK home?
Thermally broken aluminium sliding doors are warm enough for most homes, with typical whole-door U-values around 1.2–1.6 W/m²K double glazed and 0.8–1.1 W/m²K triple glazed, depending on the system. In England, a new or replacement door in an existing home with more than 60% glazing must reach 1.4 W/m²K or better, so the glass is specified to meet that. Wales, Scotland and Northern Ireland have their own rules.
How much do aluminium sliding doors cost?
Aluminium sliding doors start from a guide price of £3,295 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £4,295–£5,295, and a 4.8 m four-panel door is around £6,995. Glass, colour and threshold choices move the price within the range, and the final figure is fixed in a written quote after survey.
How do you look after aluminium sliding doors?
Aluminium sliding doors need little care: wash the frames with mild soapy water a few times a year, vacuum grit out of the bottom track and keep the drainage slots clear. A light silicone spray on the locking points once a year keeps them smooth, and rollers can be adjusted if a panel starts to drag. Manufacturer guarantees on frames, hardware and sealed units are passed to you, and our workmanship guarantee is set out in writing in your quote.
