This was our second time using Waterworks, and most definitely, our last.
Now, in 2016, a hum started which seemed to come from the same shower fixture or the adjacent Jacuzzi tub. We called up Waterworks again owing to their HomeStars' rating. The plumber arrived and said that based on the location of where the sound seemed to emanate, he needed to make a hole in the ceiling to look at the pipes. He told us that qualified as a "plumbing diagnostic (major)" and the cost was $509.06. We were desperate and so we approved the cost. The plumber found nothing amiss, and decided the hum was coming from the Jacuzzi tub, and Waterworks does not repair Jacuzzi tubs. The plumber spent 20 minutes in total in our home, and in addition to the "diagnostic" charge, the service call charge was $39.00 for a total of $619.30 with tax.
I would not be writing a negative review except for the fact that the second company I contacted, did a fantastic job. He determined that the hum was a result of a faulty valve on our humidifier attached to the furnace and the sound traveled up the wall pipes to the upstairs bathroom, and when I told him that the shower upstairs was broken but the previous plumber from WaterWorks who had worked on it could not identify the brand, he just picked up the shower wand and said, "It's stamped 'Aquabrass.'" It did take the second plumber 5 hours to determine the cause of the hum, but he charged us only $672.35 for the whole day's work.
This suggests to me that WaterWorks is overpriced and simply capitalizes from its misleading ratings on HomeStars. I will _never_ use them or recommend them again. Initially, we didn't know that we had been overcharged off until the work was fixed by another plumber at a significantly cheaper rate.
