"When I recently fitted out my new clinic, I wanted a point of difference with the flooring, so I decided to polish the existing concrete. Uninformed and after a couple of "not interested" from various contractors, I contacted Concrete Specialists NZ. They explained the process clearly and worked in with me around my hectic schedule to get the project done in a professional manner and at a very reasonable cost. I would have no hesitation in recommending Concrete Specialists NZ for any of the services they provide if you are seeking honest, professional and reliable results."

- Alvina Schonhof, Charisma Beauty owner

"I have worked with John and his team from Concrete Specialists NZ for many years and have always found them to be extremely professional in all aspects of their work. They are a great team, always on time, great with clients, and tidy up after the job is done. I would thoroughly recommend them for any concrete cutting work."

"Frontline Projects Ltd has used John Gamble and his team at Concrete Specialists NZ to carry out most of our concrete cutting, core drilling and floor grinding requirements since the company began in 2002. John is our preferred contractor for this type of work. John and his team have always been reliable, turned up to do the job on time and have always left the work site tidy. As part of our project management system we have to regularly do spot checks on rates and we have found John's rates to be competitive. We have no hesitation in recommending Concrete Specialists NZ and will continue using their services in the future."

- Jarrett Howe, Director and Project Manager – Frontline Projects Ltd.

"Concrete Specialists NZ recently ground and sealed the floors of two galleries and associated areas for Northart. I was very pleased indeed with the work they did - the floor looks great and is easy to upkeep. They completed the work ahead of schedule, worked during days and at times that were the least disruptive for gallery staff, and were thoroughly professional. In addition, they were very pleasant people to deal with. I cannot recommend John Gamble and his team highly enough."

- Wendy Harsant, Manager - Northart

"Thanks heaps for the grinding work done for us at New North Road Jetts. The comments we had from the builders / Jetts about your teams' attitudes was really positive."
