Why choose corner sliding doors in Sevenoaks?
Most homeowners choosing corner sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Which way does your Sevenoaks garden face? A corner catching south and west sun gains warmth in winter but can overheat in summer, so solar-control glass is worth considering.
A Sevenoaks garden that sits to the side as well as the rear of the house is where a post-free corner earns its place, opening the room towards both.
- When closed, the two corner panels interlock and lock together, so the glass corner stays weathertight and secure without a visible column.
- Corner systems use thermally broken aluminium sections with slim sightlines and powder-coated finishes, so the frames stay discreet on both walls.
- Because panels slide rather than fold, the corner can be opened on one side only, keeping the other side closed as a wind screen on cooler days.
Daylight in Sevenoaks and what it means for your glass
Daylight in Sevenoaks runs from about 7 h 52 min in December to 16 h 36 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.
How much do corner sliding doors cost in Sevenoaks?
Guide prices include the door, fitting and structural calculations, including VAT. The steelwork that supports the corner is designed by the engineer and priced after survey, because it depends on the building.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 3.0 m | 4 panels | £8,695–£10,595 |
| 3.6 m | 4 panels | £9,595–£11,795 |
| 6.0 m | 6 panels | £13,395–£16,295 |

How fitting works in Sevenoaks
Surveys in the TN13 district are booked at a time that suits you. Once the opening is ready and measured, manufacture is typically 4–6 weeks for aluminium, 6–8 weeks for slimline or lift and slide corners, from survey sign-off; on fitting day the frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1–2 days for the door, after 3–5 days of structural building work.
Do you need approval in Sevenoaks?
In England, forming or widening an opening is structural work that needs a Building Regulations application, structural calculations and usually a steel beam on padstones. The new door is also a controlled fitting (U-value 1.4 W/m²K or better if more than 60% glazed). If steelwork bears on a party wall, the Party Wall etc. Act 1996 may apply.
Choosing the specification
- System type. Standard aluminium, slimline or lift and slide corner systems, depending on panel size and the sightlines you want.
- Glass. Double or triple glazed safety glass, with solar-control coatings for corners facing south or west.
- Roof junction. Head details coordinated with flat roofs, roof lanterns or pitched roofs so steel, frame and roof meet neatly.
Questions about corner sliding doors in Sevenoaks
Do you fit corner sliding doors in Sevenoaks?
Yes. We survey and fit corner sliding doors in Sevenoaks and across Kent, including nearby Westerham and Tonbridge. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
Do corner sliding doors need a steel beam?
Corner sliding doors almost always need engineered structural support, because removing the corner post takes away the support for the wall or roof above. A structural engineer designs a cantilevered beam or steel frame; the calculations are included in our guide prices and the steelwork is priced after survey. In England this needs a Building Regulations application and in Scotland a building warrant; Wales and Northern Ireland have their own building control rules.
Can I add a corner sliding door to an existing house?
A corner sliding door can be added to an existing house, but it is a structural project rather than a door swap: the corner of the building has to be rebuilt with engineered steel to carry the load where the post or wall used to be. It is usually done as part of an extension or rear remodel, and a survey plus an engineer's assessment confirm what the structure above needs.
How much do corner sliding doors cost?
Corner sliding doors start from a guide price of £8,695 for 3 m of combined width across both walls, fitted, inc VAT, at standard 2.1 m height. A 4.8 m combined corner is a guide £11,495–£13,995, and 8 m combined is around £16,495. Structural steel for the post-free corner is priced separately, and the final price is fixed in a written quote after survey.
