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.
Roller garage door repairs in Derry/Londonderry: questions
Do you repair roller doors you did not fit in Derry/Londonderry?
Yes. We repair roller garage doors of any make in Derry/Londonderry and across BT48, where parts are available. If a part is no longer made, we tell you what will fit instead, or price a replacement door if that is the better option.
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.
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.
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.
Do you repair sectional or up-and-over garage doors?
No. We work on roller garage doors only, so we don't repair sectional or up-and-over doors. If you have an up-and-over door that's failing and you'd like to change it, we can replace it with a roller door; that work starts with a survey and a written quote rather than a repair visit.
Do you repair roller doors you didn't fit?
Yes. We repair electric and manual roller garage doors of any make, whoever fitted them. Tell us what the door is doing and the make of the motor or control box if you know it. That helps us confirm the visit price and, where the likely parts are clear from your description, plan for them before the visit.
