What should I know about steel roller garage doors in Letchworth Garden City?

Think about whether battery backup is worth adding, so the door keeps working for a limited number of cycles when the power is off.
Ask to see the security certificate if resistance to forced entry matters, because steel on its own doesn't make a door security-rated.
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.
Decide where the override handle will be stored, because you'll need it to wind a steel curtain up during a power cut.

Rules that apply in Letchworth Garden City

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 before it starts.

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.

Steel roller garage doors in Letchworth Garden City: questions

Can I get a price for Letchworth Garden City 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.

Do I need permission for a new roller garage door in Letchworth Garden City?

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.

What do you check at a survey in SG6?

At a survey in SG6 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 charge more for Letchworth Garden City than other towns in Hertfordshire?

No. Guide prices are the same for Letchworth Garden City 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.

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.

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.
