Garage doors in Dunedin

Garage door installation in Dunedin

Installing a door starts with the opening. Dominator says all of its doors are custom made to the exact size, so a door specialist will want the width, height, headroom and sideroom before anything is ordered. B&D NZ says its sectional doors can go up to 6.5 metres wide.

An older garage can be a tight fit. Where there is little room above the opening, Dominator's Flex-A-Door needs 80mm of headroom with its infill panel, and it is sold as a replacement for old tilt doors.

If the garage doubles as a workshop or sits under a bedroom, ask about an insulated door. B&D NZ says its insulated sectional doors have a graphite-infused EPS insulator fitted at the factory and also dampen sound. Dominator claims up to 20% better insulation than traditional EPS.

Windier than most of Otago

NIWA says Dunedin is typically windier than most of Otago all year, especially in winter. The Musselburgh station averages 14.1 km/h and records 65 days a year with gusts over 61 km/h, with 2 days over 94 km/h.

Musselburgh also holds the highest gust in NIWA's Otago records: 140.8 km/h from the west on 18 November 1984. About 14 days a year count as strong wind days, and 29% of them come in spring.

Those figures come from a single station. A garage on an exposed ridge will see more, and one tucked behind a hill far less, so describe your own section rather than the city.

Otago Harbour and the open coast

As MBIE quotes NZS 3604, exposure Zone D means coastal areas with a high risk of windblown sea-spray salt: within 500 m of the sea, harbours included, or 100 m of tidal estuaries and sheltered inlets. That takes in homes close to Otago Harbour and along the open coast.

If you are after garage door repairs in Brighton, or anywhere near the beach, rust on cables and fixings is the thing to look for. B&D NZ says to check the cables regularly for corrosion and fraying. Look from a safe distance, and leave the handling to a door specialist.
