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

Photocells can often be added to doors that only have a safety edge, if the control box allows it.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
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.

Rules that apply in Hounslow

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 Hounslow: 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 Hounslow?

Yes. We repair roller garage doors of any make in Hounslow and across TW3, TW4 and TW5, 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.

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

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

Do you cover Hounslow?

Yes. Hounslow is part of the area we cover in Greater London, including TW3, TW4 and TW5. 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.

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.
