Aluminium sliding doors in Herne Bay: what to know
The right door depends on the opening, the room and the way you use the garden. Here is how aluminium sliding doors tend to work out in practice:
Where a Herne Bay property already has aluminium windows, matching the door colour and frame profile keeps the back of the house looking consistent.
Whether you live in Herne Bay or elsewhere in Kent, 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.
- 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.
- Narrow aluminium frames and meeting stiles put more of the opening into glass, so you see more garden and less frame than with a uPVC door of the same size.
Sunlight, glass and orientation in Herne Bay
Sun angles matter for big glazed doors. Around Herne Bay, midday sun reaches about 62° in summer and drops to about 15° 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.
Typical costs for aluminium sliding doors around Herne Bay
Guide prices are the same across Kent: the fitted price depends on the size, system and specification, not your postcode. These figures are for a standard 2.1 m high door, fitted, including VAT and removal of an old door of similar size.

Survey, manufacture and fitting around Herne Bay
Here is the usual sequence in Herne Bay: guide price, free survey, written quote, then manufacture (typically 4–6 weeks from survey sign-off). Fitting typically takes 1 day for a two-panel straight swap; 1–2 days for larger doors. Nearby, we also survey in Whitstable, Canterbury and Faversham.
Do you need approval in Herne Bay?
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.
Finishes and extras for aluminium sliding doors
- Dual colour. A different colour inside and outside, so the exterior can match your windows while the interior suits the room.
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
- Colours. Standard shades such as anthracite grey, black and white, or a special RAL colour for an extra charge.
Questions about aluminium sliding doors in Herne Bay
Can you match other doors and windows in my Herne Bay 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.
Do aluminium sliding doors need Building Regulations approval?
In England, replacement sliding doors are controlled fittings, so the work is either carried out by an installer registered with a competent person scheme, who self-certifies and notifies, or notified to Building Control. The glass must be safety glazing to BS EN 12600. Forming or widening an opening is structural work needing its own application and calculations. Wales, Scotland and Northern Ireland have their own rules.
How wide can an aluminium sliding door be?
An aluminium sliding door in our range can span from about 1.5 m to 6 m, split into two to four panels. Each panel is usually up to about 2.5–3 m wide depending on the system and the weight of the glass. Wider openings take more panels, and beyond about 6 m a multi-track or lift and slide system is usually the more practical choice.
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.
