What corner sliding doors offer homes in Duns
A few practical points decide whether corner sliding doors suit a particular room and opening:
Which way does your Duns 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.
On any corner installation in Duns, the survey records floor and patio levels along both walls, because a terrace that falls differently on each side changes the threshold detail.
- Corner systems use thermally broken aluminium sections with slim sightlines and powder-coated finishes, so the frames stay discreet on both walls.
- 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.
- Daylight reaches the room from two directions, which keeps a deep extension brighter through the day as the sun moves round the house.
Light and sun in Duns
In Duns the shortest day has roughly 7 h 00 min of daylight and the longest about 17 h 34 min. The noon sun sits near 11° above the horizon in winter and 58° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.
Typical costs for corner sliding doors around Duns
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) |
|---|---|---|
| 3.6 m | 4 panels | £9,595–£11,795 |
| 4.8 m | 4 panels | £11,495–£13,995 |
| 8.0 m | 6 panels | £16,495–£20,095 |

How fitting works in Duns
Surveys in the TD11 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 Duns?
In Scotland, forming or widening an opening needs a building warrant before work starts, with structural details for the new beam. The door must meet the Scottish building standards for energy and safety glazing.
Which options matter for corner sliding doors?
- Threshold. Standard, low or flush thresholds, with drainage detailed along both elevations.
- 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 Duns
Do you fit corner sliding doors in Duns?
Yes. We survey and fit corner sliding doors in Duns and across the Scottish Borders, including nearby Eyemouth and Kelso. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
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.
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.
