We were thrilled with their professionalism and excellence that made for a smooth and stress-free build.

We asked GMac Builders to take on a large-scale outdoor project to build a deck, pergola, and sandpit. Early on, the work had to be discussed and coordinated with an earthworks company and an architect. Very professional and knowledgeable, Geoff and his team were able to come up with good solutions to work around any potential issue that came up. Our foreman, Greg, built the deck and pergola to a very high degree of workmanship leading to an outstanding end result. The large outdoor area that GMac Builders has built for us has completely transformed the house and we enjoy it every day. This was not our first time doing a building project with GMac Builders and once again, we were thrilled with their professionalism and excellence that made for a smooth and stress-free build. They have to be one of the best building companies in the country, and we highly recommend their services.

Choosing GMac Builders for our rebuild was a great choice.

The project was very well managed and stress-free as Geoff was excellent at keeping us informed of progress and helping with suggestions through each stage of the build as required. Nothing was a problem and any issues that arose were dealt with promptly and to our satisfaction. Their tradesmen and subcontractors were experienced and totally professional. All of the work was completed to a very high standard. We would not hesitate to recommend GMac Builders for reliability, professionalism and quality of work, and will definitely use them for any future projects.

We are really pleased and very proud of our new home.

Geoff kept us well-informed throughout the whole process from design to completion. Geoff’s experience and expertise enabled us to have everything on our wish list, and the quality and workmanship is outstanding. Thanks for a pleasurable building experience and a wonderful new home.

An expert builder, sound advisor, and a reasonably priced worker.

I have known Geoff McIlroy since 1994 when my wife and I purchased our house, which he had recently built to an architectural design. Over the years he has completed any work we have required of him, including a substantial extension some years ago. We regard him as an expert builder, sound advisor, and a reasonably priced worker who has become a valued friend. I have no hesitation in recommending him and his work as a builder and organizer.

We highly recommend GMac Builders.

I needed someone to do repairs after a flood in March 2014. After two earthquake repairs (both under cap through EQR) I was extremely stressed; wondering if there were only cowboys out there - cowboys only interested in making a quick dollar, making something look okay on the surface only. As it turned out – not only were there flood repairs, we found additional earthquake damage. It was a chance comment by another person that led me to GMac Builders. As well as being able to do both types of work, they are not cowboys. It was a huge weight off my shoulders. I found Geoff and his workers to be very professional and thorough. Geoff took the time to listen and answer questions, no matter how “dumb” I thought they were. He communicated well throughout the process, and regularly called in to check on progress. He and his workers were respectful that they were in someone’s home, not just on a building site. They did a great job and I am very happy. I would have no hesitation in using GMac Builders again.

We were delighted with the end result.

Geoff was recommended to us by architect Peter Milligan, to be the builder for the extension to our house. We were delighted with the end result. Geoff has excellent interpersonal skills and met with us often, always listening and offering sound advice. His staff were always pleasant and considerate. They put in a ‘false’ wall to enable us to have access to the living/dining area, and they also cleaned up every day. We are very pleased to recommend Geoff as an excellent builder.

We would like to say how delighted we are with the house and the alterations made by the GMac team.

It is always hard at the beginning of a project of this size to imagine how it will unfold and even understand what will happen along the way. In saying that, Geoff and the GMac team have not only achieved a great result for us, but made the whole experience really enjoyable throughout, even when we were challenged by the weather. In particular, their honesty and openness has meant that we never had to even consider referring back to the contract. Your recommendations for changes ensured that we now have a house that is not only practical, but also achieves our original design goals.
