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

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.
Check whether the floor dips or rises across the opening, because an uneven floor can leave a gap under the bottom rail that lets draughts in.
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.

How does it work in Hertford?

Rules that apply in Hertford

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.

Planning

Replacing a garage door is not usually development that needs planning permission. Check first if your home is listed (listed building consent covers works that affect its character), sits in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.

Insulated roller garage doors in Hertford: questions

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

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 Hertford garage so you can compare.

Is the survey in Hertford 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.

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

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.

Do you charge more for Hertford than other towns in Hertfordshire?

No. Guide prices are the same for Hertford 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.

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.

Can insulation be added to my existing roller door?

Not in a practical way. The foam sits between the two aluminium skins of each lath when it's made, so a single-skin curtain can't simply be filled or lined. Getting insulated laths means a new curtain, and because the box and barrel need to suit the larger roll, that normally means a new door, which we can quote as a replacement.
