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

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.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.

Safety edge and photocell repairs in Hemel Hempstead: questions

What should I do while I wait for a visit in Hemel Hempstead?

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 Hemel Hempstead 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 Hemel Hempstead than other towns in Hertfordshire?

No. Guide prices are the same for Hemel Hempstead as for anywhere else we cover in Hertfordshire. 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 roller doors you did not fit in Hemel Hempstead?

Yes. We repair roller garage doors of any make in Hemel Hempstead and across HP2, HP3 and HP1, 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.

Can I bypass the photocells to get the door shut?

No. Bypassing, bridging or taping over a safety device removes the protection that stops the door closing onto a person, pet or car. If the door won't close, switch it off at the isolator, keep the area clear and request a visit. Tell us if you're concerned about security when you get in touch.

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.
