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

Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

Safety edge and photocell repairs in Merthyr Tydfil: questions

Do you charge more for Merthyr Tydfil than other towns in Mid Glamorgan?

Do you cover Merthyr Tydfil?

Can I message you a photo of my garage in Merthyr Tydfil?

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

Can I get a price for Merthyr Tydfil 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.

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.
