Living in a Glasgow and Dunbartonshire flat? Structural changes to an external wall almost always need the agreement of the building's owner or the other owners, so speak to them first.
- Telling the engineer that a sliding door will sit beneath the beam lets them limit its deflection, which matters because a beam that sags can stop panels sliding freely.
- Structural calculations are included in the guide price, and the Building Regulations application is handled as part of the project, so you are not left coordinating engineers and inspectors.
- Making good the reveals and head after the steel goes in leaves a square, plumb opening, which is what a precision-made sliding door needs to run smoothly.

Questions about sliding doors for new openings in Glasgow and Dunbartonshire
Is the price different in Glasgow and Dunbartonshire?
No. Guide prices for sliding doors for new openings are the same across mainland Britain, including Glasgow and Dunbartonshire. 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 building regulations to widen a door opening?
Yes, forming or widening an opening is structural work and needs a Building Regulations application in England, supported by structural calculations. Building Control inspects the work, typically including the steel and its bearings. In Scotland a building warrant is needed. Wales and Northern Ireland follow their own building regulations through local authority or district council building control.
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 long does it take to form a new opening?
Forming or widening an opening typically involves 3–5 days of building work, including propping, cutting out, installing the steel and padstones, and making good. The sliding door is then made to the finished opening, which typically takes 4–6 weeks for aluminium, so a secure temporary closure is fitted in between. The door itself typically goes in within one to two days.
