What should I know about aluminium roller garage doors in Derry/Londonderry?
- If you want an electric door, look for a socket or fused spur near the top of the opening where the control box will go.
- Measure the space between the top of the opening and the ceiling, because the coiled curtain needs a box that is commonly around 205 to 300 mm deep or more.
- Look at the lintel above the opening for cracks or sagging, because any repair or replacement is structural work that is priced separately on survey.
- Check there is roughly 75 to 100 mm of solid wall on each side of the opening for the aluminium guide rails to fix to.

Rules that apply in Derry/Londonderry
Planning
Replacing a garage door is not usually development that needs planning permission in Northern Ireland. Listed building consent applies to listed buildings, and conservation-area controls, planning conditions or covenants can restrict changes to how a garage looks, so check before ordering.
Structural work
Structural alterations, such as widening the opening or fitting a new lintel, need building control approval from your council under the Building Regulations (Northern Ireland) 2012 before work starts.
Aluminium roller garage doors in Derry/Londonderry: questions
Can I get a price for Derry/Londonderry without anyone visiting?
Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.
What do you check at a survey in BT48?
At a survey in BT48 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.
Do you cover Derry/Londonderry?
Yes. Derry/Londonderry is part of the area we cover in County Londonderry, including BT48. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
Do you charge more for Derry/Londonderry than other towns in County Londonderry?
No. Guide prices are the same for Derry/Londonderry as for anywhere else we cover in County Londonderry. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.
How much room does an aluminium roller door take up inside the garage?
Very little. The curtain coils onto a barrel in a box at the top of the opening, so there are no ceiling tracks and nothing hangs across the roof space. You lose some height at the top for the box and a narrow strip at each side for the guide rails, both of which we measure at survey.
Can a manual aluminium roller door be made electric later?
Sometimes. A manual door can be converted to electric only if its curtain, barrel, box and guide rails are sound and compatible with a motor. If they aren't, we'll tell you at survey and price a new door instead. If you expect to want electric operation within a few years, it's usually simpler to choose it from the start.
