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

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

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 Isleworth: questions

How much is a visit in Isleworth?

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 Isleworth as elsewhere we cover.

Do you charge more for Isleworth than other towns in Greater London?

No. Guide prices are the same for Isleworth as for anywhere else we cover in Greater London. 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.

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

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 Isleworth visit date is confirmed in writing.

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

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

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.
