Why choose corner sliding doors in Cardiff?
Here is what to weigh up if you are considering corner sliding doors for a home in Cardiff:
If you are planning a wraparound extension in Cardiff, designing corner sliding doors in from the start lets the engineer size the corner steelwork alongside the roof.
Which way does your Cardiff 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.
- 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.
- 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 Cardiff and what it means for your glass
Because Cardiff sees long summer days (about 16 h 38 min) and short winter ones (about 7 h 50 min), the elevation your door faces makes a real difference. With the midday sun at about 15° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.
Corner sliding doors prices in Cardiff
Pricing does not change because you are in Cardiff: the ranges below include fitting, structural calculations and 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 |

Survey, manufacture and fitting around Cardiff
Here is the usual sequence in Cardiff: guide price, free survey, written quote, any building work, then manufacture (typically 4–6 weeks for aluminium, 6–8 weeks for slimline or lift and slide corners, from survey sign-off). Fitting typically takes 1–2 days for the door, after 3–5 days of structural building work. Nearby, we also survey in Penarth, Dinas Powys and Caerphilly.
Do you need approval in Cardiff?
In Wales, structural work to form or widen an opening needs Building Regulations approval and structural calculations, and the new door must meet the Welsh energy and safety glazing requirements. The Party Wall etc. Act 1996 may apply where steelwork bears on a party wall.
Which options matter for corner sliding doors?
- 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.
- 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 Cardiff
How soon can you survey in Cardiff?
Surveys in the CF10 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 4–6 weeks for aluminium, 6–8 weeks for slimline or lift and slide corners, from survey sign-off.
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.
How do you maintain a corner sliding door?
Maintaining a corner sliding door is much like any aluminium slider, with extra attention to the corner: keep both tracks and the corner drainage clear, wipe the corner seals, and check the meeting panels still lock smoothly. Rollers can be adjusted if a panel drops. Because a new extension can settle slightly in its first year, the corner panels may need a small adjustment after that.
How long does a corner sliding door project take?
A corner sliding door typically takes 4–6 weeks to manufacture in standard aluminium and 6–8 weeks for slimline or lift and slide systems, from survey sign-off. The steelwork and building work usually take 3–5 days before the door goes in, and fitting the door takes 1–2 days. Engineer design and approvals come first, so the door is ordered once the steel is designed.
