I contracted with Cusatis Construction Company Inc. to pour a concrete driveway, approach,pour/stamp a decorative concrete patio, and remove and replace several concrete sidewalk slabs in March. The patio was poured and stamped on Monday 5/13/13 and the driveway, approach, and sidewalk slabs were poured on 5/14/13, both the driveway/approach and patio had a protective sealer applied by Cusatis Construction on 5/14/13. The driveway received tooled expansion joints. No joints were put in the stamped patio. Weather conditions during this time were partly cloudly and the weather temperatures were in the mid 60's (ideal for pouring concrete). Less than one month later in approximately mid June I noticed three large cracks in the stamped decorative patio. Two of the cracks originate from where the patio meets the stoop and a third crack runs the entire width of the patio. The cracks go all the way through the patio and are very bad looking and ruin the appearance of the patio. I asked Marcus Cusatis to stop out and look at the patio cracks which he did on Tuesday 7/2/13. The patio did not have any expansion joints in it because Marcus Cusatis said that decorative patios he poured did not use expansion joints. However, researching stamped concrete patio reveals that expansion joints are REQUIRED just as with conventional concrete patios. It appears that the cracks are running where the joints should have been placed. When I asked Marcus if this had been a conventional concrete patio would he have installed expansion joints he said yes. At this point I asked Marcus to remove the patio and re-pour/stamp it free of charge because I felt that work he did was defective (well poured concrete should not crack one month after being poured) and not done per industry standards. Marcus Cusatis stated he would not re-pour/stamp the patio free of charge as he did not think there was anything wrong with it and did not think he had done anything wrong. Now I am stuck with a patio with several large cracks in it ruining the appearance of the stamped concrete. In addition I also have to worry about the concrete cracks opening up wider and the possibility of the broken concrete slabs heaving in the winter. I would rate the quality of the driveway as average. Some of the tooled joints are sloppily done and there is an errant glob of concrete on one slab.
