What should I know about battery backup and safety upgrades in Morden?

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.

Rules that apply in Morden

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.

Battery backup and safety upgrades in Morden: questions

Do you repair roller doors you did not fit in Morden?

Yes. We repair roller garage doors of any make in Morden and across SM4, SM3 and SM1, 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 message you a photo of my garage in Morden?

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

How much is a visit in Morden?

Prices for battery backup and safety upgrades 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 Morden as elsewhere we cover.

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

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 Morden visit date is confirmed in writing.

Can safety devices be added to an older electric door?

Usually, if a compatible safety edge or photocells are available for the control box. 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 it can be done, and the price, before booking the visit.

How often should I test the safety edge and photocells?

Test them monthly, following the manufacturer's instructions for your door. The aim is to confirm that the door stops or reverses when the safety edge meets an obstruction, and won't close while the photocell beam is broken. If either test fails, don't keep using the door until it has been checked, and request a visit.
