I’m dropping one star since two of the 4 sprinkler values failed and they way they were installed, the entire manifold system needed to be removed and reinstalled. Very disappointing considering the amount of money I paid to have this done. FIRST Review Overall Great Value! Bob and his team are wonderful to work with and I would recommend Bob’s Grading for their grading skills for anyone’s backyard. When we first bought the house, there was an addition added to the house. The former contractors didn’t do the proper job with the excess dirt after the project. The addition left extra dirt pushed in places it shouldn’t have been and the drainage of the entire backyard was leaning towards the house. With Bob’s extensive knowledge of grading, he was able to propose a solution to the drainage issue, and offered great ideas to make things even better than our original landscaping plan. The proposal was to lower the entire backyard by several inches and add drainage. I have to admit that I was skeptical about such a dramatic move, so I asked a lot of questions and Bob was happy to explain why and the overall process. By removing the excess dirt, the yard was transformed into a workable space for future landscaping taking into account several factors of grading, drainage, design and the surrounding yards. They were flexible with changes and offered suggestions from years of experience of how to improve our design when asked. His staff were professional and efficient in their work. I also had comfort in knowing they were securing the fence to ensure the safety of our dogs nightly. We did get lower quotes, but I was confident that Bob had the closest vision to what I saw of the landscaping. I am confident that the value of the dollars spent on the grading and drainage was superb and worth every penny.
