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 UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.
Roller garage door motor replacement in Morden: questions
Do you charge more for Morden than other towns in Greater London?
No. Guide prices are the same for Morden as for anywhere else we cover in Greater London. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.
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.
What should I do while I wait for a visit in Morden?
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 Morden visit date is confirmed in writing.
How much is a visit in Morden?
Prices for roller garage door motor replacement start from £395 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Morden as elsewhere we cover.
Should I replace the motor or the whole door?
Replace the motor when the rest of the door is sound: the curtain runs straight, the laths are undamaged, and the guides and barrel are in good order. If several major parts are worn, or the door has other recurring faults, a new door may be better value. The engineer will tell you plainly what they find.
Why does my roller door motor hum but not move?
A humming motor that doesn't turn the barrel can mean the motor has failed, but it can also point to an obstruction, a curtain jammed in the guides or a fault in the control box. Stop pressing the button, keep clear of the door and don't force the curtain. A repair visit diagnoses the cause before any parts are quoted.
