Rules that apply in Aylesbury

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.

Electrics

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.

Safety edge and photocell repairs in Aylesbury: questions

What should I do while I wait for a visit in Aylesbury?

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 Aylesbury visit date is confirmed in writing.

Yes. We repair roller garage doors of any make in Aylesbury and across HP20, HP19 and HP21, 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.

How much is a visit in Aylesbury?

Prices for safety edge and photocell repairs start from £99 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 Aylesbury as elsewhere we cover.

Can I message you a photo of my garage in Aylesbury?

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 Aylesbury. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.

Why does my roller door reverse when nothing is in the way?

A door that reverses on its own while closing is often reacting to a safety device that thinks there's an obstruction. Dirty or misaligned photocells, a damaged safety edge, a loose cable or limits that have drifted can all cause it. Clean the photocell lenses and check the beam is clear, then request a visit if it continues.
