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

Wider openings usually suit 77 mm laths for rigidity, so expect the lath size to be confirmed once the width has been measured at survey.
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.
Measure the headroom above the opening carefully, because insulated laths make a bigger roll than single-skin and need a deeper box.
Think about how the garage will be used in future, since choosing insulated laths now avoids replacing the door if it becomes a hobby or utility space.

Rules that apply in Blackheath

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.

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Insulated roller garage doors in Blackheath: questions

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

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.

Can you remove my old garage door in Blackheath?

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

Can I get a price for Blackheath 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 you charge more for Blackheath than other towns in Greater London?

No. Guide prices are the same for Blackheath as for anywhere else we cover in Greater London. 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.

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.

Is an insulated door worth it for a detached garage?

It depends on how you use the garage. If it's only for parking or storing tools, single-skin laths may be enough. If you work out there, store anything that dislikes the cold, or want it quieter, insulated laths are worth the extra cost. Remember the walls, roof and floor also let heat out, so the door is only part of the picture.
