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

Find out whether there's a socket or fused spur near the box position, since every steel door we price is electric.
Check the lintel above the opening for cracks or sagging, since a heavier steel curtain relies on sound fixings at the top.
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.
Measure the width of your opening, because our steel price list covers singles up to 2.4 m and doubles of 3.0 to 4.0 m, and other widths are priced on survey.

How does it work in Dorchester?

Once you accept, the fitting date is confirmed in writing, depending on installer availability. If a new spur is needed, it's shown in the quote and fitted by a qualified electrician.

Rules that apply in Dorchester

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 Dorchester: questions

How long does it take to fit a roller garage door in Dorchester?

Most single domestic roller doors are fitted in a day once the door has been made, including removing the old door. Wider doors, conversions that need building work and jobs where power has to be run can take longer; the quote says what to expect.

Do I need permission for a new roller garage door in Dorchester?

Replacing a garage door is not usually development that needs planning permission in England, and widening the opening needs building control approval. If you live in a listed building, a conservation area or on an estate with covenants or planning conditions, check before ordering.

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

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

Is an electric roller door worth it for a garage in Dorchester?

That depends on how often you use the garage. An electric door opens from the car with a remote and has safety devices fitted, while a manual door costs less and suits occasional use. We price both for your Dorchester garage so you can compare.

Can I repaint a steel roller door later?

When you order a new steel door, you can choose a RAL colour or woodgrain finish as a priced extra, and colours outside the manufacturer's range are priced on survey. If you're thinking of repainting the door years later, check the manufacturer's care guidance first, as their warranty terms for the door are set out in writing in your quote.

Is a steel door the right choice for a row of lock-ups?

It can be, particularly where a stiffer curtain appeals for garages that are opened less often. Every steel door in our price list is electric, though, so each garage needs a power supply near its box. Where lock-ups have no power, manual aluminium doors may be more practical. We can survey and price a whole row together.
