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

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.
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.
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.

How does it work in Magherafelt?

Once you accept the quote, we confirm your fitting date in writing, which depends on installer availability. On the day, the door is fitted, commissioned and handed over with its paperwork.

Rules that apply in Magherafelt

Structural work

Structural alterations, such as widening the opening or fitting a new lintel, need building control approval from your council under the Building Regulations (Northern Ireland) 2012 before work starts.

Electrics

An electric door needs a power supply near the roller box. Part P does not apply in Northern Ireland, but electrical work must still meet BS 7671 and be carried out by a qualified electrician.

Insulated roller garage doors in Magherafelt: questions

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

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

Can I get a price for Magherafelt 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.

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

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 Magherafelt garage so you can compare.

Is the survey in Magherafelt 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.

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.

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.
