Low-headroom roller garage doors in Derry/Londonderry

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.

That depends on how often you use the garage. An electric door opens from the car with a remote and has safety devices fitted, while a manual door costs less and suits occasional use. We price both for your Derry/Londonderry garage so you can compare.

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.

Lath size is one of the things that decides box size, because larger laths make a bigger roll. On narrower doors a smaller lath can help where headroom is tight. On wider doors, though, larger laths add the rigidity the curtain needs, so there's a balance to strike. We recommend the lath at survey based on your width, height and headroom.

Occasionally an opening has no headroom inside, no wall above it outside for a face-fitted box, and too little height to lose any under the lintel. There can still be options, such as altering the lintel, which is priced on survey. If we can't find a sensible solution, we'll tell you plainly rather than fit something that won't work.
