What should I know about roller garage doors with vision and vent laths in Derry/Londonderry?

Think about privacy, because vision laths can let people glimpse what's inside when the garage light is on after dark.
Ask whether vision or vent laths are covered by the certificate if you're choosing a security-rated door model.
Plan vision or vent laths into your order from the start, because they're built into the curtain when the door is made.
Check the agreed position of the laths in your written quote, and again on fitting day before the installer finishes.

Rules that apply in Derry/Londonderry

Electrics

An electric door needs a power supply near the roller box. Part P does not apply in Northern Ireland, but electrical work must still meet BS 7671 and be carried out by a qualified electrician.

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.

Roller garage doors with vision and vent laths in Derry/Londonderry: questions

Is an electric roller door worth it for a garage in Derry/Londonderry?

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.

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.

Can I message you a photo of my garage in Derry/Londonderry?

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.

How long does it take to fit a roller garage door in Derry/Londonderry?

Most single domestic roller doors are fitted in a day once the door has been made, including removing the old door. Wider doors, conversions that need building work and jobs where power has to be run can take longer; the quote says what to expect.

Can vision laths be added to my existing roller door?

Vision and vent laths are built into the curtain when a new door is made, which is why we offer them as an extra on new doors. Changing laths in an existing curtain depends on finding compatible laths for that door, so if you want daylight or ventilation in your current garage, it's usually simplest to plan them into a replacement door.

Can I have vision laths on an electric roller door?

Yes. Vision and vent laths are part of the curtain, so they coil onto the barrel and run in the guides like the rest of the laths, whether the door is manual or electric. An electric door with vision laths is commissioned in the usual way, with the limits set and the safety edge or photocells tested.
