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

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

Battery backup and safety upgrades in St Austell: questions

Do you repair roller doors you did not fit in St Austell?

Yes. We repair roller garage doors of any make in St Austell and across PL25, PL26 and PL24, 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.

Do you charge more for St Austell than other towns in Cornwall?

No. Guide prices are the same for St Austell as for anywhere else we cover in Cornwall. 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 cover St Austell?

Yes. St Austell is part of the area we cover in Cornwall, including PL25, PL26 and PL24. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.

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.
