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

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

Rules that apply in Witham

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 Witham: questions

How much is a visit in Witham?

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 Witham as elsewhere we cover.

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

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

Can I get a price for Witham 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.

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.

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.
