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

Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
Never tape over, bridge or bypass a safety device to make an electric roller door close.

Powered door safety

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 Chatham: questions

Can I get a price for Chatham 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.

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 charge more for Chatham than other towns in Kent?

No. Guide prices are the same for Chatham as for anywhere else we cover in Kent. 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.

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

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

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.
