  • “Nathan and Connah have been a dream to work with. I have been extremely impressed with their work, their work ethic and their ability to be reactive to my vendors’ needs. Nothing has been a big deal and they have helped me get several sales now across the line for my very thankful vendors. 10/10 recommend!”

  • Thank you to the team at Mammoth! Really happy with our home upgrades. Amazing friendly service, such a smooth and seamless process! 10/10 would recommend!

    Chloe Johnston

  • Absolutely rate Mammoth Building. Nathan and Connor felt part of the family while they were building us a brand new bathroom, a real family orientated business, fantastic communication at all times, and made the whole renovation completely stress free. Their standards are high, changed plans on the fly, and even coped with the cat overseeing their work regularly (🙄). Thankyou Jay, Nathan, Connor and Cam for giving us such a beautiful new bathroom

    Nicki Sutton

  • Friendly and approachable guys who know what they are doing. They completed the jobs at our place to a really high standard. Easy and straight forward communication. Highly recommend
