These guys are an exceptional outfit. I had old carpet ripped up and the ozgrind team turned an old floor into a beautiful area for my kids to play. They did a grind and seal on 50m2 of old concrete. The team was on time, Thier communication was 10 out of 10 and the finished product was amazing. I went with a bigger company and I was not disappointed. A few areas of my floor were troublesome and they spent the time getting it right. Can't recommend them enough.
