We hired Julio and his crew to demo the existing, cracked concrete patio and walkway in our back yard and replace it with an expanded patio with stones of our choosing. The scope also included creating a pathway from our driveway to the new, rear patio, exterior drainage, and gently slope run off (vs. having a retaining wall). We figured it would be quite the undertaking since they also had to support the roof during this undertaking, as the area below, was being demo'ed and replaced. I called for an estimate and the response was immediate. Within a couple of days, Julio was out at the house and the estimate was done within minutes. We had an idea of what we wanted ahead of time, and Julio provided us with guidance on the design, drainage, and overall scope. Not only was it quick, but the bid was very reasonable, and Julio made us feel at ease with the choice of design, scope, timeline and price. Our design included Nicolock Blue Ridge Pennsylvania Blue pavers with Holland Stone Granite City-Blend edging, custom curbing, Pennsylvania Blue Stone stepping stones, and reseeding the grass (where it was dug up or mowed over with the forklift). Shortly after Julio left the house, we were encouraged to choose our pavers from a supplier of our own choosing, and on the day I chose to go to the supplier, Julio met me there to make sure that I was able to get the pavers I wanted, in the right amount and contractor's pricing. I handled the ordering and Julio's crew handled the install. Within the week, work began. The crew showed up early and stayed late, and was supervised by Julio's son (who also worked). They went above and beyond to get things done quickly, and made sure that the overhanging roof of our home was properly supported when they removed the columns to install the pavers (and then replaced the columns with our new selections). The only thing that delayed the project was a little afternoon rain. Even so, the work was done on schedule. Each day, everyone showed up on time, if not early. All of the crew members worked together like a well oiled machine and the project went off without a hitch. And every afternoon, Julio would show up to ensure that there were no issues and that we were satisfied with th eprogress. He even waited for me to get out of work, which was sometimes after 6:00 PM. We can't think of a single complaint during this project. The crew also created a walkway from the front to the rear of our home, with Pennsylvania Blue Stone stepping stones, and even asked me exactly where I wanted the stones (within the reach of my own steps, which I thought was very considerate. When the stones and drainage were complete, they brought in fertized soil and applied frass seed and cover to ensure that the lawn would grow back as if the patio and stepping stones were always there. We highly recommend Julio Calderon and Tun Tun Construction for any hardscaping/landscaping project, and plan to use them again when we are ready to resdesign and add to our yard.
