We purchased a home with an irrigation system installed by Oliver Irrigation. A few weeks ago my husband was doing some landscaping and when Oliver Irrigation came to do the spring startup noticed that there was an issue with one zone. They asked me to have the area dug up and to call them and they would come and fix the issue. We did so, they were here within the same day and fixed the issue in the most courteous and professional manner even when my husband didn't dig in the right location. Wayne & Mike got in the dirt elbow deep, found the issue fixed it, tested everything and replaced some heads to get optimal coverage and all with smiles and pleasant conversation. Cannot say enough good things about this company. We've had 3 visits from them and each and every one is fast, efficient and really nice guys.
