Discuss the warranty before choosing this company.
I had to have my main shut off valve replaced, as it was very old and not properly closing anymore. I had some small jobs to complete that required proper water shutoff, it also made me nervous that if there was an issue the water could not be shutoff. Obviously that was a disaster waiting to happen.
Pro-Star was very accommodating as the city had some challenges finding the main shutoff on my property and created some scheduling issues. The plumber showed up on time and the work was completed quickly, although I felt it was a expensive.
Unfortunately, one of the welds above the new ball valve let go within about 36 hours, and released a fair amount of water in a semi isolated space in my basement, and subsequent water damage. Fortunately I was able to turn the water off after discovery, and Pro-Star made it a priority to come out and fix it right away.
The resulting damage is not something that I cannot fix myself. I spent several hours with a rented rug doctor to suck up the water in the carpets, and then shampoo the carpets with an oxy based cleaner to prevent mildew and mold from forming in the future. I need to replace several baseboards and framing boards as these are all MDF, and do not take well to water. Not overly expensive to replace, but will cost a little, and my time to repair. The Ikea bedframe in the room took some damage as well, (particle board/MDF) but it is older, and seems as though it will survive.
Although I have given several reasons why I was happy with the service of Pro-Star, and their response to the issue, I have given them a two Star rating due to their warranty and response to my request that they revisit my bill due to the issue. I made an inquiry two weeks ago, requesting a discussion on the situation. I have not received a response at all, even to tell me they would not be giving me a discount or any reduction on my bill. Although I appreciate that the warranty does state that they will not be held liable for damages caused by workmanship, I think that this was an instance where at least a conversation would have been appropriate. I paid over $530 for this valve replacement, which as I stated, I felt was a little expensive. For example, I had one of my hot water tanks, all new copper piping, valves and new venting (to code) all done for only 1500 (including the new high efficiency tank, old tank removed etc.), and the workmanship is exceptional.
I would encourage a buyer beware in this case, as the warranty does not cover damage to your home if there is a workmanship issue. I was not looking for a full reduction of my bill, just enough to cover the costs of the material for repair. I know that Pro-Star never had any intention of causing the damage that resulted from their work. Unfortunately, I did not even warrant a call back to check on the subsequent repair, any damages, nor in response to my inquiry.
