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

After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
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.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.

Rules that apply in Dereham

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 Dereham: questions

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

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 Dereham. 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 Dereham?

Yes. We repair roller garage doors of any make in Dereham and across NR19, 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 get a price for Dereham 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 charge more for Dereham than other towns in Norfolk?

No. Guide prices are the same for Dereham as for anywhere else we cover in Norfolk. 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 photocells be added to a door that doesn't have them?

Often, if the control box has a connection for them. Some older systems need extra wiring or a replacement control box first. Tell us what's on the control box label and we'll confirm whether photocells can be added, and the price, before booking. Our battery backup and safety upgrades page covers adding devices.

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.
