What should I know about double and wide roller garage doors in Derry/Londonderry?

Allow extra headroom for a wide door, since larger laths make a bigger roll and need a deeper box.
Decide whether one wide door or two single doors suits how you use the garage, especially if there is a central pier.
Look along the lintel for cracks or sagging, because a wide door's box is fixed along its full length.
Think about electric operation for any opening over 4 m, since the wide doubles in our price list are all electric.

Double and wide roller garage doors in Derry/Londonderry: questions

Is the survey in Derry/Londonderry 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.

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 I need permission for a new roller garage door in Derry/Londonderry?

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.

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.

Is a manual roller door practical on a double garage?

It can be, but only up to 4 m in our price list, and you'll be lifting a long curtain by hand each time, even with spring assistance. For a garage opened every day, or anyone who would find that hard work, an electric door is usually the better choice. Wide doubles between 4 and 5.5 m in our price list are electric.

Do I need permission to turn two garage openings into one?

Removing a pier and fitting a longer lintel is structural work, and it may need Building Regulations approval. Whether planning permission is needed depends on your property, so check with your local authority, especially for listed buildings or homes in a conservation area. Our guide to planning and building regulations covers the questions to ask.
