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

Look for a socket or fused spur near the top of the opening, as every insulated door in our price list is electric.
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.
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.

Insulated roller garage doors in Carrickfergus: questions

Can I get a price for Carrickfergus 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.

What do you check at a survey in BT38?

At a survey in BT38 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.

Is the survey in Carrickfergus 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 I message you a photo of my garage in Carrickfergus?

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

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.

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.
