Rules that apply in Blackburn

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 Blackburn: questions

Do you cover Blackburn?

Yes. Blackburn is part of the area we cover in Lancashire, including BB1 and BB2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

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

How much is a visit in Blackburn?

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 Blackburn as elsewhere we cover.

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

Yes. We repair roller garage doors of any make in Blackburn and across BB1 and BB2, 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.

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.

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.
