Are corner sliding doors right for your Crediton home?
Most homeowners choosing corner sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Where steel for a Crediton 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 Crediton 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.
- 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.
- 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.
Sunlight, glass and orientation in Crediton
Sun angles matter for big glazed doors. Around Crediton, midday sun reaches about 63° in summer and drops to about 16° 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.
How much do corner sliding doors cost in Crediton?
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 |
| 4.0 m | 4 panels | £10,295–£12,495 |
| 4.8 m | 4 panels | £11,495–£13,995 |

How fitting works in Crediton
Surveys in the EX17 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 Crediton?
A new or wider opening in England needs Building Control approval for the structural work as well as compliance for the door itself under Approved Documents L and K. Expect structural calculations, a steel beam and, where a party wall is involved, notices under the Party Wall etc. Act 1996.
Finishes and extras for corner sliding doors
- Panel layout. Two panels per side for smaller corners or three per side for wider ones, with fixed panels at the far ends.
- 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 Crediton
Do I need building approval for corner sliding doors in Crediton?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
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.
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.
