What should I know about up-and-over to roller door conversion in Caernarfon?
- Taking out the up-and-over tracks frees the garage ceiling for shelving, storage or better lighting.
- Clear width can improve slightly after a conversion, because there are no swing-out arms at the sides of the opening.
- Electric conversions are commissioned with force testing to BS EN 12453 and a Declaration of Conformity at handover.
- If headroom behind the lintel is short, the roller box can go under the lintel or be face-fixed on the wall.

Rules that apply in Caernarfon
Structural work
Widening the opening, removing a central pier or fitting a new lintel is structural work that needs Building Regulations approval from building control in Wales before it starts.
Planning
Replacing a garage door is not usually development that needs planning permission in Wales. Check first if your home is listed (listed building consent covers works that affect its character), is in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.
Up-and-over to roller door conversion in Caernarfon: questions
What do you check at a survey in LL55?
At a survey in LL55 we measure the width and height of the opening, the headroom above it for the roller box, the side room for the guide rails and the floor level. We also look at the lintel and where power can come from for an electric door.
Is the survey in Caernarfon really free?
Yes. For a new door, a replacement or a conversion, the survey is free and there is no obligation to go ahead. We measure the opening, check the lintel, headroom, side room and power, and send a written quote afterwards.
Can you remove my old garage door in Caernarfon?
Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Caernarfon address, along with standard fixings and making good to the reveals. If the frame or lintel needs work, we price it at the survey before you agree.
Do I need permission for a new roller garage door in Caernarfon?
Replacing a garage door is not usually development that needs planning permission in Wales, and widening the opening needs building control approval. If you live in a listed building, a conservation area or on an estate with covenants or planning conditions, check before ordering.
Will I lose height in the opening with a roller door?
Not usually, if the box can sit behind the lintel inside the garage, which is the normal position. If there's too little headroom inside, the box can go under the lintel, which does reduce the clear opening height, or be face-fixed on the front of the wall. We measure this at the survey and tell you before you commit.
Is converting from up-and-over to roller worth it?
It depends on how you use the garage and the drive. A roller door doesn't swing out, so you can park closer; it frees the garage ceiling; and insulated laths cut draughts and noise compared with an uninsulated panel. The free survey and written quote give you the actual figure to weigh against those benefits.
