Steel roller garage doors in Derry/Londonderry

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.

Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Derry/Londonderry. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Replacing a garage door is not usually development that needs planning permission in Northern Ireland, and widening the opening needs building control approval from your council. If you live in a listed building, a conservation area or on an estate with covenants or planning conditions, check before ordering.

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.

The steel doors in our price list are electric, because a steel curtain is heavier than an aluminium one and the tubular motor does the lifting. If you want a hand-operated door, our manual doors use single-skin aluminium laths. Where there's no socket near the box, a qualified electrician can fit a fused spur from an existing circuit, shown as a separate line in your quote; a new supply to a garage with no power is priced on survey.

Use the manual override, normally an internal crank or winding handle that turns the barrel by hand. Keep it somewhere you can find quickly. A steel curtain is heavy, so take your time and wind steadily. If you'd rather not crank it, battery backup keeps the door running for a limited number of cycles while the power is off.
