Based on their outstanding Angie's List reviews, I contacted Wilson Irrigation to repair and modify my existing irrigation system. I wanted Wilson to slightly modify/expand my system to accommodate some recent landscape changes, refocus a few inefficient sprinkler heads, and repair a visible leak. However, the work recommended by Wilson was much more comprehensive. In addition to fixing the leak (which they identified as being related to the backflow), they recommended replacing every sprinkler head in the front yard, and installing an entirely new system in the back yard. I argued against the need for such comprehensive work (since I believed that my fully functional system only needed some tweaking), but the Wilson rep was insistent, and I ultimately followed his professional advice. I did so, again, based on the company?s great reviews and the rep?s assurance that the system would be VERY significantly improved. Unfortunately, after work was completed, I was extremely dissatisfied based on a variety of issues. For example, coverage in the back yard (after installing an entirely new system) was only marginally different from the coverage prior to the work. Wilson was very responsive to my concerns, and a second service professional evaluated the completed work. He agreed with all of my complaints, identified solutions, and also identified some additional issues. For example, he suggested that a section of sprinkler heads in my front yard be moved closer together as he believed that their current placement made coverage inefficient and too prone to spray onto my driveway. Based on his recommendations, a second crew redid some of the original work and also performed supplemental work (at no cost to me). After work was completed this second time around, the system was still less than perfect, and in some ways, less efficient than my original system: watering too much in some areas, not enough in others, etc. Furthermore, some of the supplemental work (although complementary) seemed totally unnecessary, as water still sprayed directly onto my driveway (the problem that was supposed to have been alleviated), etc. At this point, I opted to stop working with Wilson (who seemed unable to meet my needs), and I hired a different irrigation company (at a fraction of the price) who very successfully performed the simple tasks that I originally wanted Wilson to perform: refocusing heads to improve coverage and reduce waste, etc. In all, my initial instincts (which I should have followed) about this work were accurate: there was no legitimate rationale for replacing (or significantly modifying) an existing system that was fully functional (ie, if it ain?t broke, don?t fix it). The only portion of the Wilson job that I feel was successful (and necessary to begin with) is the backflow repair (a few hundred dollars of this nearly $2000 expenditure).
