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

The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.

Rules that apply in Thamesmead

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Safety edge and photocell repairs in Thamesmead: questions

How much is a visit in Thamesmead?

Prices for safety edge and photocell repairs start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Thamesmead as elsewhere we cover.

Can I message you a photo of my garage in Thamesmead?

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 Thamesmead. Send them by WhatsApp or mention them in your enquiry, and we will reply 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 Thamesmead than other towns in Greater London?

No. Guide prices are the same for Thamesmead as for anywhere else we cover in Greater London. 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.

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.
