Kostaris Construction built a two-story addition on our house last year, and we could not have been more pleased with the results. This is a builder who pays close attention to fine details and clearly takes pride in its workmanship. The workmanship was first-rate in every respect, and the job was completed ahead of schedule. Also, the cost was very reasonable, lower than the competing bidders for the job. Finally, after the job was completed and we had moved in, when we discovered a minor problem (as the result of the record snowfall of last winter), we learned that the company stands by its work: they came out and fixed the problem right away. We would not hesitate to use this company again or to recommend it to any of our friends.
