Always on time and always on site when on the day he said he would be there. Lots of attention to details. Great work and always puts the extra effort in to make the job perfect.

We have hired Cosar Construction twice now for concrete projects at our home, firstly for a driveway and most recently, for a large backyard patio this spring. The driveway has stood up to heavy use and based on the quality of workmanship, I fully expect the patio will too. Mario was professional and explained the process for both jobs so we new what we were getting into. He and his crew finished on schedule and were accommodating of requests along the way. We are very happy with the outcomes and highly recommend Corsar to anyone looking for quality concrete work at a fair price.
