Portland sprinklers did a phenomenal job installing a new sprinkler system in our entire yard with extensive mature established landscaping. They had to hand dig around existing walls, paths, structures, lighting, trees, shrubs and all types of terrain. There was no damage of any kind. It was almost impossible to tell what areas were dug to install the water lines and sprinkler heads. We would definitely use them again, they are a superb team.
