Safety edge and photocell repairs in Letchworth Garden City: questions
Do you repair roller doors you did not fit in Letchworth Garden City?
Yes. We repair roller garage doors of any make in Letchworth Garden City and across SG6, SG5 and SG15, 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.
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.
What should I do while I wait for a visit in Letchworth Garden City?
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 Letchworth Garden City visit date is confirmed in writing.
Do you cover Letchworth Garden City?
Yes. Letchworth Garden City is part of the area we cover in Hertfordshire, including SG6, SG5 and SG15. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
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.
Why does my roller door reverse when nothing is in the way?
A door that reverses on its own while closing is often reacting to a safety device that thinks there's an obstruction. Dirty or misaligned photocells, a damaged safety edge, a loose cable or limits that have drifted can all cause it. Clean the photocell lenses and check the beam is clear, then request a visit if it continues.
