Does your lawn have brown spots? If it does it might be a sign your irrigation system needs repairs. When repairs need to be made, we will ask for your prior approval. If you are considering changing your landscape, it is important to consider changes to your irrigation system. Sometimes relocating trees or shrubs will require changing or moving sprinkler heads to more effectively water your new landscape. In addition, if you have had your irrigation system for a number of years you may want to consider a tune-up. As your landscape grows, heads may need to be adjusted or relocated in order to ensure your entire yard is effectively watered. It is important to remember to protect your landscape investment with an adequate irrigation system.
