They did a wonderful job. They arrived on time and went straight to work. They consulted with us regarding the different zones for our sprinklers and explained how they could improve the water flow and performance. They were very efficient and did exactly what they said they were going to do, which included replacing a few sprinkler heads. The price was actually a little less than we had discussed when we scheduled the work. It has been several months since they came out, and our sprinkler system still works perfectly.
