What should I know about steel roller garage doors in Merthyr Tydfil?

Decide where the override handle will be stored, because you'll need it to wind a steel curtain up during a power cut.
Check the lintel above the opening for cracks or sagging, since a heavier steel curtain relies on sound fixings at the top.
Find out whether there's a socket or fused spur near the box position, since every steel door we price is electric.
Compare steel with insulated aluminium if a warmer garage is a priority, as it's the foam-filled lath that reduces heat loss.

How does it work in Merthyr Tydfil?

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 Merthyr Tydfil

Structural work

Widening the opening, removing a central pier or fitting a new lintel is structural work that needs Building Regulations approval from building control in Wales before it starts.

Electrics

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

Steel roller garage doors in Merthyr Tydfil: questions

Can I get a price for Merthyr Tydfil without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

How much do steel roller garage doors cost in Merthyr Tydfil?

Our guide price for steel roller garage doors is from £1,345 inc VAT. The figure for your garage depends on the opening size, the door specification and any extras, and is confirmed in a written quote after a free survey. The guide prices are the same in Merthyr Tydfil as elsewhere we cover.

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

Replacing a garage door is not usually development that needs planning permission in Wales, 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.

What do you check at a survey in CF47?

At a survey in CF47 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.

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.

How do I open a steel roller door in a power cut?

Use the manual override, normally an internal crank or winding handle that turns the barrel by hand. Keep it somewhere you can find quickly. A steel curtain is heavy, so take your time and wind steadily. If you'd rather not crank it, battery backup keeps the door running for a limited number of cycles while the power is off.
