Installing a sprinkler system is a great idea if you want to keep your yard looking nice. The nice thing about a good sprinkler system is that you can pre-program a timer to start your sprinklers any time day or night. If you are out of town, you do not have to worry about asking a neighbor to water your lawn. Go with a professional company to do the job. If they are reputable and professional they will complete an estimate for you before they even begin the work. Many can even design the landscape and work that into the cost of the estimate. Installing the system may be more than just putting in the water system. You may decide to redo your yard completely.
