"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."

"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."
