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

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.
Look for a socket or fused spur near the top of the opening, as every insulated door in our price list is electric.
Measure the headroom above the opening carefully, because insulated laths make a bigger roll than single-skin and need a deeper box.
If the garage is integral, consider how much cold air and noise currently reaches the rooms that share a wall or ceiling with it.

Rules that apply in Dartford

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 Dartford: questions

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

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.

How much do insulated roller garage doors cost in Dartford?

Our guide price for insulated roller garage doors is from £1,495 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 Dartford as elsewhere we cover.

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

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

Do you cover Dartford?

Yes. Dartford is part of the area we cover in Kent, including DA1, DA2 and DA8. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

Will an insulated door fit the same opening as my old single-skin door?

Usually, yes, but insulated laths are thicker, so the curtain makes a bigger roll in the box. If your old door had a small box, the new one may need more headroom, a box fitted under the lintel, or a face-fitted box. We check this at survey and explain the trade-offs before you choose.
