"I found Ralph on Angie's list and contracted him for a clogged drain. I was pleased that he responded quickly and he took care of 2 clogged shower drains. The following week, my hot water heater broke and Ralph called back five minutes after I sent him a text. He replaced it with a superior model (which cost only a little more than the cheap model that I had and he explained the features which made it superior. I later found a YouTube video which confirmed everything that he said). The warranty was better also. He came back the following day to replace two toilets which had been causing leaks in my kitchen ceiling. I'm very happy with my new water efficient toilets which flush with more force than the previous ones, and, no more leaks! While Ralph was replacing my water heater, he noted problems with the installation of my 35 year old boiler and pointed out issues that a more modern and energy efficient boiler would address. There was no hard sell, just a matter of fact recommendation that I might consider replacing it before next winter. I've been hiring contractors for the past 22 years, and I'm impressed by Ralph's knowledge, experience and professionalism. If you call for service, you will get Ralph himself, not a random plumber that a larger company will send. I've already booked Ralph again for my broken sump pump!"

"We have a very complicated hot water heating system with 5 valves. We called WaterMac because 2 of our zones were not working correctly as recommended by Home Advisor. Igor and his assistant came to analyze very shortly after. The specialists took care making sure that they knew what the problem was. They came back on the next business day and fixed the problem. They were efficient, effective and professional."

"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."
