What should I know about safety edge and photocell repairs in Chalk Farm?

Never tape over, bridge or bypass a safety device to make an electric roller door close.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.

Rules that apply in Chalk Farm

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 Chalk Farm: questions

Can I message you a photo of my garage in Chalk Farm?

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

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.

How much is a visit in Chalk Farm?

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 Chalk Farm as elsewhere we cover.

Do you charge more for Chalk Farm than other towns in Greater London?

No. Guide prices are the same for Chalk Farm 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.

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.
