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

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 either side of the opening stop the door closing while anything is breaking the beam between them.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.

How does it work in Dover?

We confirm the visit price and the likely part before anything is booked. The visit date depends on engineer availability and is confirmed in writing.

Rules that apply in Dover

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 Dover: questions

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

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 Dover visit date is confirmed in writing.

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

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

Do you repair roller doors you did not fit in Dover?

Yes. We repair roller garage doors of any make in Dover and across CT17 and CT16, 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.

Do you cover Dover?

Yes. Dover is part of the area we cover in Kent, including CT17 and CT16. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

Can I bypass the photocells to get the door shut?

No. Bypassing, bridging or taping over a safety device removes the protection that stops the door closing onto a person, pet or car. If the door won't close, switch it off at the isolator, keep the area clear and request a visit. Tell us if you're concerned about security when you get in touch.
