Are corner sliding doors right for your Corby 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 Corby 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.
On any corner installation in Corby, the survey records floor and patio levels along both walls, because a terrace that falls differently on each side changes the threshold detail.
- Each elevation can have its own number of panels and its own sliding direction, letting the opening suit the shape of the garden and the furniture layout.
- 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 reaches the room from two directions, which keeps a deep extension brighter through the day as the sun moves round the house.
How much sun will a door in Corby get?
Daylight in Corby runs from about 7 h 39 min in December to 16 h 50 min in June, with the noon sun at roughly 14° and 61° 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.
Guide prices for corner sliding doors in Corby
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.

Timescales for corner sliding doors in Corby
Surveys in the NN17 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 Corby?
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.
Options to consider for your corner sliding door
- Threshold. Standard, low or flush thresholds, with drainage detailed along both elevations.
- Panel layout. Two panels per side for smaller corners or three per side for wider ones, with fixed panels at the far ends.
- Colours. Single or dual colour powder coating, so the outside can match the extension cladding or render.
Questions about corner sliding doors in Corby
Do I need building approval for corner sliding doors in Corby?
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 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.
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.
