Large and oversized sectional garage doors in Dyfed
We supply and fit large sectional doors across Dyfed, including Llanelli, Ammanford, Aberystwyth and Carmarthen, with a free survey and a fixed written price for every door.
Large and oversized sectional garage doors are made-to-measure doors for openings taller or wider than a standard domestic garage, such as motorhome and caravan garages, oak-framed barns, coach houses and triple-width openings. They use heavier panels, springs and track sets, but work in the same way: the door rises vertically and parks under the roof.

What should you know about large sectional doors in Dyfed?
When is a door oversized?
Anything taller than about 2.3 metres or wider than a typical double, roughly 5 metres, usually moves into larger spring and track specifications. Motorhome garages often need heights of 3 metres or more.
What about oak-framed and timber buildings?
Doors can be fixed to timber frames, but the fixings and any packers have to suit the frame, and green oak moves as it dries. The survey checks the frame and the fixing positions.
Can large doors be insulated and glazed?
Yes. Most large doors use insulated panels, and window rows or vision panels can be added to bring light into a long garage.
Which options can you choose?
- Vision rowsWindows across one section.
- High-lift tracksUse roof height so the door parks higher.
- Shaft or rail operatorSpecified to the door size.
- Heavier springsSpring sets sized to the larger door weight.
How much does a large sectional door cost in Dyfed?

At the free survey we measure everything the manufacturer needs, check the brickwork, lintel and floor, and agree the door details with you.
What rules apply in Dyfed?
In Wales, replacing a garage door with one of similar appearance is normally treated as minor work that does not need planning permission. Listed buildings, conservation areas, Article 4 directions and any planning conditions on your property can change that, so check with your local planning authority first if any of these apply.
Planning authorities in Dyfed include Carmarthenshire Council and Ceredigion Council.

Questions about large and oversized sectional garage doors in Dyfed
Will a large door need a special motor?
It needs an operator rated for its size and weight, which may be a heavier rail operator or a shaft-mounted unit.
Can a sectional door go in an oak barn?
Usually. The fixing method is matched to the frame, and allowance is made for timber movement.
Can you fit a sectional door to a motorhome garage?
Yes, provided the building has the height and structure for the tracks and the door. We measure headroom, side room and depth at survey.

Do I need planning permission in Dyfed?
