We moved into our current house in July 2010, and it came with an inground sprinkler system. I had no idea how to set it up nor how to repair some of the issues the system had. I found Richmond Hill Sprinklers online, read some reviews and called. They are now my regular "go-to" people for the system. They helped me get it going, taught me how to use it, repaired everything that needed it and they handle seasonal chores.
They are prompt, flexible around my schedule and their fees are very competitive. Al and his team are professional and obviously know what they are doing. I would highly recommend them to anyone needing this type of service.
