Rules that apply in Derry/Londonderry

Planning

Replacing a garage door is not usually development that needs planning permission in Northern Ireland. Listed building consent applies to listed buildings, and conservation-area controls, planning conditions or covenants can restrict changes to how a garage looks, so check before ordering.

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.

Roller garage door replacement in Derry/Londonderry: questions

Is the survey in Derry/Londonderry 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 you remove my old garage door in Derry/Londonderry?

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

What do you check at a survey in BT48?

At a survey in BT48 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.

Do you charge more for Derry/Londonderry than other towns in County Londonderry?

No. Guide prices are the same for Derry/Londonderry as for anywhere else we cover in County Londonderry. 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.

How long will a new roller garage door last?

Lifespan depends on use, exposure and care rather than a fixed number of years. Keeping the guide rails clean, using only the lubricant the manufacturer allows, testing the safety devices monthly and having the door serviced all help. The manufacturer's warranty terms for your door and motor are set out in writing in your quote.

Can you replace a roller door made by a different company?

Yes. We replace roller garage doors of any make, and up-and-over doors too. The old door is removed and disposed of as part of the price, so it doesn't matter who made or fitted it. What matters is the opening itself, which we measure afresh at the free survey before quoting.
