Why choose sliding doors for new openings in Dunbar?
Most homeowners choosing sliding doors for new openings want the same things: more light, a clear view and a door that is easy to live with.
Turning a Dunbar kitchen window into a door to the garden? Check where drains, gullies and air bricks sit outside, because they can affect the new threshold.
Where a Dunbar house has a bay, chimney breast or upstairs window directly above the planned opening, the engineer will need to account for it in the steel design.
- A structural engineer sizes the steel beam and padstones for the actual loads above, so the opening is designed rather than guessed.
- The door is measured from the finished opening rather than from drawings, so it fits the opening as built, not as it was intended to be built.
- Temporary propping holds up the wall above while the masonry is cut out, keeping floors, ceilings and the roof safely supported throughout the work.
Daylight in Dunbar and what it means for your glass
Because Dunbar sees long summer days (about 17 h 37 min) and short winter ones (about 6 h 57 min), the elevation your door faces makes a real difference. With the midday sun at about 11° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

Questions about sliding doors for new openings in Dunbar
Is the price different in Dunbar?
No. Guide prices for sliding doors for new openings are the same across mainland Britain, including Dunbar. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
Do I need a steel beam for sliding doors?
A widened or new opening usually needs a steel beam or a suitable lintel to carry the wall and anything above it, and for wider openings a steel beam is the usual answer. A structural engineer chooses the size and bearing details based on the loads. The beam is placed on padstones at each end to spread its load into the masonry.
Can you turn a window into a sliding door?
Yes, a window opening can usually be extended down to the floor and often widened to take a sliding door. The work involves removing the masonry below the window, forming a new threshold, and fitting a steel beam or lintel if the opening is widened. Drains, air bricks and floor levels outside need checking, and the work needs a Building Regulations application.
How much does it cost to widen an opening for sliding doors?
Our guide price for forming or widening an opening is £3,595 for 2.4 m and £4,495 for 4.8 m, covering steel, padstones, making good and structural calculations. The door is priced separately, and Building Control fees are set by your council. All figures are guide prices inc VAT, fixed in a written quote after we survey the wall and see what is above it.
