I called WaterWorks after reading the reviews on HomeStars. My original call was what I thought was a leak behind a wall. When Larry, the technician arrived, he immediately knew what the issue was (expansion), explained it to me, and mentioned it didn't need to be fixed.
I then asked him to install shut-off valves in my kitchen and upstairs bathroom as well as check the dishwasher hookup, which the previous owner had covered with an old cloth and elastic bands. He explained that the hookup had an old valve and was leaking water when it was turned. He explained what work needed to be done and provided a quote before he began. He then quickly went to work and fixed all issues cleanly and promptly.
Although I perhaps could have called around for a more competitive quote, I'm glad I chose WaterWorks. (The price I have listed includes their service plan.) Their customer service is outstanding, and Larry was very friendly, courteous and clean while in my home.
If I had another plumbing job, I would call WaterWorks first.
