What should I know about steel roller garage doors in County Londonderry?

Measure the width of your opening, because our steel price list covers singles up to 2.4 m and doubles of 3.0 to 4.0 m, and other widths are priced on survey.
Look at the brick or blockwork on each side of the opening, as the guide rails for a steel door need solid reveals to fix to.
Compare steel with insulated aluminium if a warmer garage is a priority, as it's the foam-filled lath that reduces heat loss.
Decide where the override handle will be stored, because you'll need it to wind a steel curtain up during a power cut.

Rules that apply in Northern Ireland

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.

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and CE marking, which is the marking that applies to machinery placed on the market in Northern Ireland.

Questions about steel roller garage doors in County Londonderry

Are guide prices the same across County Londonderry?

Yes. The guide prices are the same in every town in County Londonderry. The written quote reflects your opening and the door you choose, not your postcode.

How do I book a survey in County Londonderry?

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.

Do I need permission for a new roller garage door in County 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.

How do I open a steel roller door in a power cut?

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.

Can I repaint a steel roller door later?

When you order a new steel door, you can choose a RAL colour or woodgrain finish as a priced extra, and colours outside the manufacturer's range are priced on survey. If you're thinking of repainting the door years later, check the manufacturer's care guidance first, as their warranty terms for the door are set out in writing in your quote.
