What should I know about up-and-over to roller door conversion in Hertfordshire?
- If headroom behind the lintel is short, the roller box can go under the lintel or be face-fixed on the wall.
- Electric conversions are commissioned with force testing to BS EN 12453 and a Declaration of Conformity at handover.
- An up-and-over frame is kept only if it is sound and square; otherwise it comes out and the opening is prepared.
- We check the lintel and reveals at the survey, and price a new lintel or building out the reveals before you agree.

Rules that apply in England
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 before it starts.
Planning
Replacing a garage door is not usually development that needs planning permission. Check first if your home is listed (listed building consent covers works that affect its character), sits in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.
Questions about up-and-over to roller door conversion in Hertfordshire
Can I get a price without anyone visiting?
Yes. The guide price tool takes four steps and gives a range for your opening and door type, or the visit price for a repair. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.
How do I book a survey in Hertfordshire?
Start with the guide price tool or the form on this page. We then contact you to arrange a free survey for a new door, replacement or conversion, and confirm the date in writing.
Which towns do you cover in Hertfordshire?
We cover Hertfordshire, including Watford, Hemel Hempstead, Stevenage and St Albans. Every town has its own page with local details, and you can start a guide price for any postcode in Hertfordshire online.
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.
Can you keep my existing up-and-over frame?
Sometimes. If the frame is sound, square and securely fixed, it can stay as a finish around the opening and the roller door is fitted to suit it. If it's rotten, damaged or out of square, we take it out and prepare the opening for the new door. The survey decides which applies to your garage.
