What should I know about steel roller garage doors in Portishead?

Look at the brick or blockwork on each side of the opening, as the guide rails for a steel door need solid reveals to fix to.
Think about whether battery backup is worth adding, so the door keeps working for a limited number of cycles when the power is off.
Compare steel with insulated aluminium if a warmer garage is a priority, as it's the foam-filled lath that reduces heat loss.
Find out whether there's a socket or fused spur near the box position, since every steel door we price is electric.

Rules that apply in Portishead

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.

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.

Steel roller garage doors in Portishead: questions

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

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 Portishead. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Can you remove my old garage door in Portishead?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Portishead address, along with standard fixings and making good to the reveals. If the frame or lintel needs work, we price it at the survey before you agree.

What do you check at a survey in BS20?

At a survey in BS20 we measure the width and height of the opening, the headroom above it for the roller box, the side room for the guide rails and the floor level. We also look at the lintel and where power can come from for an electric door.

Do you cover Portishead?

Yes. Portishead is part of the area we cover in Somerset, including BS20. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I have a manual steel roller door?

The steel doors in our price list are electric, because a steel curtain is heavier than an aluminium one and the tubular motor does the lifting. If you want a hand-operated door, our manual doors use single-skin aluminium laths. Where there's no socket near the box, a qualified electrician can fit a fused spur from an existing circuit, shown as a separate line in your quote; a new supply to a garage with no power is priced on survey.

Why are steel doors over 4 m wide priced on survey?

Our standard steel price list covers single openings up to 2.4 m and doubles of 3.0 to 4.0 m; other widths are priced on survey. A wider steel door needs the opening, lintel and fixing points checked individually before the right door can be specified, so we price it after the survey rather than from a table. For openings up to about 5.5 m, insulated aluminium doors have a set price band you can see online.
