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

Photocells can often be added to doors that only have a safety edge, if the control box allows it.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.

Rules that apply in Gainsborough

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 Gainsborough: questions

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

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 Gainsborough visit date is confirmed in writing.

How much is a visit in Gainsborough?

Prices for safety edge and photocell repairs start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Gainsborough as elsewhere we cover.

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 cover Gainsborough?

Yes. Gainsborough is part of the area we cover in Lincolnshire, including DN21. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
