What should I know about insulated roller garage doors in Isleworth?

Measure the headroom above the opening carefully, because insulated laths make a bigger roll than single-skin and need a deeper box.
Decide whether you want extras such as battery backup or a wireless keypad, so they can be included in the written quote rather than added later.
Check whether the garage has other weak spots, such as a single-glazed window or a gappy side door, that will still let heat out after the new door goes in.
If the garage is integral, consider how much cold air and noise currently reaches the rooms that share a wall or ceiling with it.

How does it work in Isleworth?

Rules that apply in Isleworth

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.

Insulated roller garage doors in Isleworth: questions

Is the survey in Isleworth really free?

Yes. For a new door, a replacement or a conversion, the survey is free and there is no obligation to go ahead. We measure the opening, check the lintel, headroom, side room and power, and send a written quote afterwards.

Can you remove my old garage door in Isleworth?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Isleworth 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.

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

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 Isleworth garage so you can compare.

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

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.

Is an insulated door more secure than a single-skin one?

Not automatically. Insulation and burglary resistance are separate qualities. How well a door resists attack depends on how that specific manufacturer's model has been tested, for example to LPS 1175 or STS 202. If security is a priority, look at our security-rated doors, which are also insulated, and we'll show you the certificate for the exact model.

Are insulated roller doors available in different colours?

Yes. Insulated doors come in the manufacturer's standard range finishes, and you can choose a RAL colour or a woodgrain effect as a priced extra. Colours outside the manufacturer's range are priced on survey. If you're matching windows or a front door, have the RAL code to hand when you ask for a guide price.
