Getting a new garage door installed in Nowra
A new door is made to fit the opening, not the other way round. Steel-Line says its sectional doors are made at least 25mm wider than the opening on each side and 30mm taller, so a 2130mm high opening takes a 2160mm door.
The space beside the opening matters too. B&D's guide asks for 120mm of side room for a standard Panelift, 140mm with its Smoothtrack wheels and 195mm with its Auto-Lock. Roller doors need room above the opening for the roll instead, so a measure decides between the two.
The Shoalhaven after the Currowan fire
The NSW SES lists its Nowra unit under the Shoalhaven, the city that took the Currowan fire. Started by lightning on 26 November 2019, it burnt 499,621 hectares and destroyed 312 homes, with 173 damaged and 1,889 saved, according to Wikipedia's list of the season's fires.
On bush fire prone land, the RFS says Planning for Bush Fire Protection sets protective measures, and the style, materials or siting of a building may have to change. CSIRO adds that garages and sheds rated BAL-12.5 or above may need specific measures, which can include the door.
Contracts, insurance and wiring in NSW
Legal Aid NSW says home building work over $5,000 must be in writing, and that contractors need Home Building Compensation insurance for work over $20,000. It also says those rules do not cover garage doors, so a door-only job sits outside them.
Wiring is covered. In NSW a Certificate of Compliance for Electrical Work must be lodged for any electrical work that installs, adds to or alters electrical equipment, which includes a new power point for an opener.
Around Nowra
Bush fire prone land
The Shoalhaven's map is prepared by council and signed off by the RFS. Check your block on the RFS online tool before you choose a door.
Near the Shoalhaven River
The SES names the Shoalhaven River as a flood catchment. If the garage has taken water, keep the opener off until it is checked.
Checking a licence
Service NSW's online licence check lets you look up whoever does the wiring before work starts.
What we would do
Even though a door-only job sits outside the NSW contract rules, get the quote in writing with the door's make, model and size. If anything is wrong at handover, that page is what you point to.
