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

Photocells can often be added to doors that only have a safety edge, if the control box allows it.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.

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 Stevenage

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 Stevenage: questions

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 repair roller doors you did not fit in Stevenage?

Yes. We repair roller garage doors of any make in Stevenage and across SG1, SG2 and SG4, 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 Stevenage?

Yes. Stevenage is part of the area we cover in Hertfordshire, including SG1, SG2 and SG4. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I get a price for Stevenage without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

Do you repair safety devices on any make of roller door?

Yes. We repair and replace safety edges and photocells on electric roller garage doors of any make, provided compatible parts are available for the control box. We don't work on sectional or up-and-over doors. If a compatible part isn't available, we'll explain the options before anything is booked.

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.
