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

After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
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.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.

Safety edge and photocell repairs in Alfreton: questions

Do you cover Alfreton?

Yes. Alfreton is part of the area we cover in Derbyshire, including DE55. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

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 Alfreton visit date is confirmed in writing.

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.

Do you charge more for Alfreton than other towns in Derbyshire?

No. Guide prices are the same for Alfreton as for anywhere else we cover in Derbyshire. 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.

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.
