    "Nick has recently completed the grinding of our concrete swimming pool to remove the existing paint film and prepare it for replastering. He also ground a retro plaster finish off a large exterior concrete wall. Nick was an absolute pleasure to deal with. He turned up when he said he would and had outstanding communication. We really appreciate all your hard work and working around tricky weather and builder's movements, Nick - thank you! We have no hesitation in recommending Zero9 Concrete Services."

He also filled in a large crack and the floor is so much better now than it was before. I would definitely recommend Nick at Zero9concrete Works who will do an excellent job for you."

    "Nick and Annette Rangi of Zero9concrete was hired to hone and seal concrete block cladding. They could not do the job to a satisfactory level. Instead I had to hire another team to fix what they have done. The grinding was substandard. The waterproofing / priming was badly done. I will be recovering all remedial costs, plus delays and scaffolding costs from them. Feel free to contact Bowers who supplies these Masonary blocks to verify this. Bowers are aware of their workmanship, and they can pass on my details to verify.

    They walked off the job when given the opportunity to rectify their work. Instead they are trying to invoice me for the substandard work.
    Nick and Annette Rangi responded:
    "Philip from Ravenstone Homes engaged us to hone and seal blocks. The honing was completed and Philip confirmed he was happy with it. We did a sample for the sealing and top coat finish. Philip approved us to proceed. When we had finished the entire job, Philip advised us he wanted an alternative finish. We advised we would be happy to do that, and would provide a quote. Philip said either redo all the work for free or don't return to site. We tried to engage and find a reasonable way forward, but Philip refused. We have 20+ years in concrete, and deliver top quality work. Our work was inspected and confirmed as high quality, but unfortunately this was not accepted by Philip. We are really disappointed with this outcome and feel it is fair and reasonable to charge for the work completed, and accepted. Other contractors on this site have had similar issues. Take care when working for this developer. "

    "Nick did a fantastic job applying a product to stop damp coming up through the concrete floor, and then sealed with a low sheen product, that will enable ease of cleaning, and looks fantastic. The job was done within timeframes required, and at a very reasonable price. I would highly recommend Zero9services for any concrete work. Thanks for your great service"

    "Nick did a great job grinding and tidying up my front steps in preparation to be tiled and I would recommend zero9concreteworks for any concrete grinding jobs you might have. Nick was personable and communicated well at every point in the job process and was committed in making sure the job was completed well and that I was happy with the finished product. "

    "Nick and Annette honed and sealed our block house in Mangawhai. The honing was finished with a high sheen finish both on internal walls and external. Nick displayed an in-depth knowledge of concrete and concrete blocks, and worked to ensure we were making informed decisions. The job was done to perfection, and we are extremely happy with the finish. We would totally recommend the workmanship to others."

    "We used Nick to hone and seal a wall of interior facing blocks (hotblocs). Did a great job - really impressed.

    What’s really great about Zero9 Concrete is their communication. From arranging initial site visit on the day we first contacted through to a quick quote and daily updates on how the job progresses - this really makes this team easy to work with.
