Why choose aluminium sliding doors in Sevenoaks?
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:
Whether you live in Sevenoaks 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.
If your Sevenoaks home has a rear extension or kitchen-diner, aluminium sliding doors let you place a table close to the glass, because no panel swings into the room.
- 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.
- Panels run on adjustable tandem rollers along a hard-wearing track, so even a heavy double or triple glazed panel can be opened smoothly with one hand.
- A polyamide thermal break inside every profile separates the cold outer metal from the warm inner face, cutting heat loss and reducing the risk of condensation forming on the frame.
How much sun will a door in Sevenoaks get?
At the latitude of Sevenoaks, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 52 min against 16 h 36 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.

Survey, manufacture and fitting around Sevenoaks
We plan the job around your home in Sevenoaks: survey first, then a written quote, then manufacture (typically 4–6 weeks from survey sign-off). The fitting itself usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors. If you are in Westerham or Tonbridge, the same process and prices apply.
Rules for aluminium sliding doors 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.
Finishes and extras for aluminium sliding doors
- Glass. Double or triple glazed units in toughened or laminated safety glass, with solar-control or self-cleaning coatings.
- 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.
Questions about aluminium sliding doors in Sevenoaks
Can you match other doors and windows in my Sevenoaks 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 long do aluminium sliding doors take to arrive?
Aluminium sliding doors typically take 4–6 weeks to make after you sign off the surveyed specification, because each door is built to measure and powder coated to order. Fitting a straight swap of a two-panel door typically takes 1 day, and larger doors 1–2 days. These are typical times rather than promises, and we confirm a date once the order is placed.
