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

Never tape over, bridge or bypass a safety device to make an electric roller door close.
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.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.

Rules that apply in Amersham

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 Amersham: questions

Can I get a price for Amersham 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.

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

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 Amersham visit date is confirmed in writing.

How much is a visit in Amersham?

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 Amersham 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.

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.

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.
