Why people call us back
Windsor manufacture our sectional and roller doors at their South Auckland facility. They've been supplying quality garage doors across NZ for almost 30 years, and we're proud to be their trusted partner servicing from the Harbour Bridge to the Brynderwyns.
From quote acceptance to installation, we work hard to make it a seamless process. If required, we can have your door operational in two weeks. Architectural doors require a longer lead-in time.
Has your door failed? Car stuck inside? We can normally get a technician with you the same day. If not, we will point you in the right direction to get a speedy outcome.
Our Windsor made COLORSTEEL® range is engineered locally to withstand the toughest conditions. This industrial grade durability comes with a rock-solid 10 year warranty. Choose COLORSTEEL®. Trusted by Kiwis.
Locally owned, serving Warkworth, Mangawhai and Silverdale. We know which products last in North Auckland conditions.
As a qualified plumber, Chris sets the 'tone' in the business amongst his colleagues. A stickler for standards, there are no shortcuts. The core philosophy is "Do it once, do it right". Quality service; quality product; happy days...
Like most businesses, we offer FREE, no obligation quotations. Our prices are very 'fair and reasonable' and tailored to suit most budgets.
Call us today and Chris will take your call direct and answer your questions. If you need a new door, he'll measure and quote and often install it. No sub-contractors or middle people. Keep it simple...

The people doing the work
A family business you can trust
Chris owns Garage Door Group and still does the quotes himself. When you ring the number on the ute, he's the one who picks up, which is why nothing gets lost between the quote, the order and the install.
We started as Warkworth Garage Doors and grew into Silverdale and Mangawhai. Same team, same trucks, one name.
Talk to ChrisQuestions we get asked
It depends on the size of the opening, the type of door and whether you are adding a motor or insulation, so we quote after measuring rather than guessing over the phone. The measure and quote are free and carry no obligation. If your existing door can be repaired rather than replaced, we will tell you that instead.
Mostly it comes down to how the door will look against your house, and how close you are to the sea. The profile and the colour are what people spend the time on, so we bring samples to the free measure rather than leaving you to judge it off a printed swatch. Salt air is the other factor, because it is what ends a door near the water, and it decides between steel and aluminium. Headroom occasionally rules a sectional door out, and we check that while we are there.
Very often, yes, and we would rather do that. Springs, cables, rollers, sensors, seals and motors are all serviceable parts, and a repair on a structurally sound door costs a fraction of a new one. Replacement makes sense when panels are corroded or damaged, or when the door is old enough that parts are no longer available. We will tell you which you have.
We have technicians on the road across North Auckland and Rodney every day, so usually quickly. If your door is stuck, will not close or has a broken spring, phone rather than emailing and tell us what it is doing, because that gets you into the day's run. A door that will not close is a security problem and we treat it as urgent.
Yes, and that is most of our repair and servicing work. It makes no difference who supplied the door, who fitted it or how old it is. We work on sectional doors of any brand, residential and light commercial roller doors, aluminium and timber doors, and openers of any make. Bringing us in does not void a manufacturer warranty, and we will tell you if one still applies to your door.
Yes, in two ways. Take a photo of your garage, mark the door on our door builder, and try every COLORSTEEL colour on your own house before you speak to anyone. Then we bring physical samples with us to the free measure, so you can hold the real colour against your cladding and your roof, in the light the door will actually live in. A screen never quite matches what ends up on the wall, which is why we do both rather than one.
