Why choose corner sliding doors in Dorking?
These are the points a surveyor will go through with you when you choose corner sliding doors for a home in Dorking:
Where steel for a Dorking corner extension would bear on a shared wall, the Party Wall etc. Act 1996 (England and Wales) may apply, so it is worth raising with neighbours early.
Which way does your Dorking 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.
- When closed, the two corner panels interlock and lock together, so the glass corner stays weathertight and secure without a visible column.
- 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.
- With no post at the corner, sliding both sets of panels back opens the meeting point of two walls completely, so the room spills straight onto the patio.
Planning glass for the light in Dorking
At the latitude of Dorking, 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 35 min in midsummer. A south-facing corner sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.
Corner sliding doors prices in Dorking
These figures are for the door supplied and fitted, with the engineer's 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. Your price is fixed in a written quote after survey.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 3.0 m | 4 panels | £8,695–£10,595 |
| 6.0 m | 6 panels | £13,395–£16,295 |
| 8.0 m | 6 panels | £16,495–£20,095 |

Survey, manufacture and fitting around Dorking
Nothing is ordered until you sign off the surveyed specification. The door is made from the finished opening sizes (typically 4–6 weeks for aluminium, 6–8 weeks for slimline or lift and slide corners, from survey sign-off), and fitting usually takes 1–2 days for the door, after 3–5 days of structural building work. If you are in Reigate or Redhill, the same process and prices apply.
Rules for corner sliding doors in England
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
- Glass. Double or triple glazed safety glass, with solar-control coatings for corners facing south or west.
- Colours. Single or dual colour powder coating, so the outside can match the extension cladding or render.
- Threshold. Standard, low or flush thresholds, with drainage detailed along both elevations.
Questions about corner sliding doors in Dorking
Do you fit corner sliding doors in Dorking?
Yes. We survey and fit corner sliding doors in Dorking and across Surrey, including nearby Reigate and Redhill. 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 lose more heat?
Corner sliding doors lose heat in proportion to their glazed area, so a large glass corner loses more than a solid wall would, but thermally broken systems keep typical whole-door U-values around 1.2–1.6 W/m²K double glazed. In England, a new door in an existing home with more than 60% glazing must achieve 1.4 W/m²K or better, and triple glazing is available. Wales, Scotland and Northern Ireland apply their own energy rules.
How big can a corner sliding door be?
A corner sliding door in our range typically covers about 3 m to 8 m of combined width across both walls, usually four panels up to about 4.8 m and six panels above that. The two sides do not need to be equal. Panel height starts at the standard 2.1 m and can go taller depending on the system, which is confirmed at survey alongside the structural design.
Is the open corner a weak point for security?
The corner of a corner sliding door is not a weak point when the system is properly specified, because the two meeting panels interlock and lock together, typically with multi-point hardware at the corner as well as on the sliding edges. Laminated glass adds resistance to breaking through. Corner systems are available tested to PAS 24, and the locking specification is confirmed in your quote.
