What should I know about remote control and keypad upgrades in Derry/Londonderry?

Handsets and keypads are priced individually, so your confirmation shows the visit and each item you have chosen.
A smart receiver is only fitted where the door has both a safety edge and photocells, re-tested at fitting.
Rolling-code handsets are matched to your door's receiver, paired during the visit and tested before we leave.
Recoding after moving house means only the handsets you hold can open the door, whatever the previous owners kept.

How does it work in Derry/Londonderry?

On the day, the receiver is recoded and new handsets or keypads are paired and tested. Any other parts the door needs are quoted before they're fitted.

Rules that apply in Derry/Londonderry

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.

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.

Remote control and keypad upgrades in Derry/Londonderry: questions

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

Can I get a price for Derry/Londonderry without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

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.

What should I do while I wait for a visit in Derry/Londonderry?

If the door is stuck part-open, keep people, pets and cars clear of it and switch off the power at the isolator if it is safe to reach. Do not force the curtain or open the roller box. Your Derry/Londonderry visit date is confirmed in writing.

Can you add a remote to a manual roller door?

Not on its own. A manual door has no motor or receiver for a remote to talk to, because springs in the barrel balance the curtain and you lift it by hand. To operate it by remote, the door first needs a manual-to-electric conversion, which is only possible when the curtain, barrel, box and guides are sound and compatible.

Can I buy a remote online and code it myself?

Sometimes, but only if the handset is compatible with your receiver, and many aren't. Rolling-code systems need the right handset type and the correct pairing steps from the motor maker. If you'd rather not risk buying the wrong one, tell us the make of your control box and we'll supply matched handsets and pair them during the visit.
