Our Backyard and pool were done before by a different contractor but unfortunately we found a lot of problems (bad water drainage, patio stones moving, etc.). We decided to redo our backyard with Rob and his team from Core Precision Interlock Inc. . They did an outstanding job. Rob did the redesign and his proposal was great. It was a larger project, so they started the first part of the job in the fall (which was mostly cleanup) and then second part of the job finished it in early spring. They are very well organized. They did a lot - reconnected and moved all pool equipment, added the Armor Stone Wall due to big slope of our backyard, made all required drains, made the interlock with very nice patterns and put the flagstone on the patio, then made the landscaping. Quality of the job is outstanding. From our experience, Robert was professional, honest, and very hard working. I would recommend Robert Pasutto from Core Precision Interlock Inc. for any job with interlock and more. Now our backyard, patio and pool look amazing.
