What should I know about steel roller garage doors in Coleraine?

Measure the width of your opening, because our steel price list covers singles up to 2.4 m and doubles of 3.0 to 4.0 m, and other widths are priced on survey.
Compare steel with insulated aluminium if a warmer garage is a priority, as it's the foam-filled lath that reduces heat loss.
Ask to see the security certificate if resistance to forced entry matters, because steel on its own doesn't make a door security-rated.
Find out whether there's a socket or fused spur near the box position, since every steel door we price is electric.

Steel roller garage doors in Coleraine: questions

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

How much do steel roller garage doors cost in Coleraine?

Our guide price for steel roller garage doors is from £1,345 inc VAT. The figure for your garage depends on the opening size, the door specification and any extras, and is confirmed in a written quote after a free survey. The guide prices are the same in Coleraine as elsewhere we cover.

Do you cover Coleraine?

Yes. Coleraine is part of the area we cover in County Londonderry, including BT52. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Is the survey in Coleraine 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.

Is a steel door the right choice for a row of lock-ups?

It can be, particularly where a stiffer curtain appeals for garages that are opened less often. Every steel door in our price list is electric, though, so each garage needs a power supply near its box. Where lock-ups have no power, manual aluminium doors may be more practical. We can survey and price a whole row together.

How do I open a steel roller door in a power cut?

Use the manual override, normally an internal crank or winding handle that turns the barrel by hand. Keep it somewhere you can find quickly. A steel curtain is heavy, so take your time and wind steadily. If you'd rather not crank it, battery backup keeps the door running for a limited number of cycles while the power is off.
