We hired Ernesto Duran to build a backyard retaining wall (from 3 quotes with other builders in the area). He built a beautiful, well crafted and high quality wall (see pictures) which was about 50 feet long and 36 inches high, turning an original 45 degree hill slope to an almost level foundation. He and his crew built the retaining wall in about 3 full days of work. We chose the Manorstone blocks (6" x 12" x 16") from Mutual Materials. In addition, Ernesto fully landscaped our backyard by removing the old grass and all of the weeds and replaced it with new grass and planted about 30 new plants as well as moving/replanting the existing bushes and trees. If you are looking to top quality, then Ernesto Duran is the Retaining wall/Landscaper" to hire. Feel free to contact me if you have any questions.
