I can only say wonderful things about Jim. He's very honest and knowledgeable. I hired him to do…read morethe plumbing in a bathroom that we are installing in our basement. He did an amazing job. I recently called him back when we installed the toilet because it was leaking and we couldn't figure it out and he was incredibly reasonable trouble shooting it (Turns out we had a bad toilet from Home Depot). We will hire him for some additional work next year! Will absolutely recommend all day long.

Had a complete, new boiler installed in June, Jim talked with me for hours to help me decide the…read morebest solution. Very professional installation, and naturally, no leaks! During my research phase, Jim always presented the answer to my questions with a complete, long term benefit as the focus, his suggestions were made based on many boiler and heating details that we lay folk might not grasp, so understandably, a complex situation may not initially present a clear and simple explanation which a lay person will grasp. Jim will help you with that. Jim did a first class job of fixin... no, correcting my original plumbing kluge job - I personally installed the boiler which he replaced. He personally stands by his work, and has no problem with answering your calls. I know this because I've hired and consulted CARNIC for over 10 years, including having them clean my first boiler every few years. BTW, yes, I know it should be cleaned annually, but Jim does such a thorough job, it runs well for much longer than one year. I selected a modern design pin type boiler (New Yorker), I added a tank type hot water heater which uses a circulation zone for the source of heating the water (SuperStor Ultra, indirect heating), and 2 microprocessor control systems. Yeah, didn't need all that, but the controller which adjusts burn time according to outdoor temperatures was a key component which does not come with the boiler. Looking to this coming winter, hoping to see greatly reduced fuel consumption (compared to my original Weil-McLane when it was at its' peak).

A nightmare. I hired both Ryan and his dad for a brand bew build. Appeared to being going along…read more as scheduled. Then Ryan's dad passed away. Didn't see much of him after that. When he finally returned. We had many setbacks. Alot of back and forth with threats on both ends. I was left with mini splits that had no heat. He came out to repair. When I reported that I still didn't have heat. I haven't seen him since. This is after giving him 24 000 dollars. Then my ceiling had a major leak. We had to tear down all the sheetrock and insulation. I sent him pictures. Still no response. 2000.00 repair. I'm preparing to go to court after I get all the receipts. This review is with RJK plumbing and heating.

His sub was unprofessional, indicating every step of the way that this was a "favor". I spoke to Ryan about my installation concerns repeatedly throughout construction. We finally got to finish and needed to open up every wall because at every shower location and two sinks the piping needed to be redone. We had a water fall into the first and second floor at two locations. DO NOT HIRE. My family and I are currently without heat.

My niece wanted to file with bbb. She research this company and he had his license suspended. I was like what ? She showed me. The company is shady. They also come into our house with dirty feet and not cover over their shoes. We don't like that. They need to respect people's house.

Something lets go, there's the sound of rushing water, and the whole downstairs fills up with steam. It was so thick I couldn't even see a foot in front of me in the basement as my plumber, Darren Powers, talked me through on the phone how to shut the furnace down, and which valve to turn to get the water to stop. Man! What a mess.... Darren was such a help to me. Though he had been up since early that morning working a job when I reached him at around 7:00 pm, he came over as soon as he could around 9:00 pm and worked on stabilizing things until about 10:30 pm so nothing else would happen. Because it was Saturday, he wasn't able to come back until Monday after gathering all the parts and equipment needed to fix the furnace and burst pipe line. I've known Darren for years, and he's helped me on many occasions. Each time, he came as soon as he could, did great work, and cleaned up the resulting mess after. I've trusted him numerous times to come in to do his work even when I wasn't home. And he's always been more than fair with not only his prices, but also his time. It doesn't get any better than that. Thanks, Darren. You're not only a great vendor, but I'm glad to have you as a friend.

They had to come back because they didn't put the back piece of the toilet on correctly, it was rocking.They had to come back a third time because now there was a constant smell. They caulked around the toilet. For the next 7 months the smell would come back, sometimes a little, sometimes unbearable. BUT then I started getting little sewer flies. I was not calling them. I found Gardner Johnson on Yelp. It was a blessing. He listened. He looked. He fixed. The previous company had not set the ring correctly, and there was sewage literally sitting under my toilet. Anything you need plumbing wise, you would be wise to pick Johnson Plumbing. He also sent his assistant to help with another issue with my septic system. The assistant saved me at least a thousand dollars from a previous professional telling me what I needed to do. He showed me pictures proving it did not need to be done. They both were so professional, so great and they guarantee their work. But I am sure you will never .ever . have them come back for the same reason.

This review will be much like the visit I just had with my local plumber: short…read more A guy who I *think* is the infamous "DJ" came to my house to repair a small yet steady leak coming from the water trap beneath my sink. After quickly assessing the damage, he presented me with two options: rebuild and reseal the current trap or outright replace it. Since the former was the cheaper option and had a pretty good chance of ameliorating the leak, I opted for the rebuild and reseal. Total price for the job: $140. All things considered, this business is very affordable and prompt. Their response time is ultimately what led me to elect them for my plumbing repairs. Best of all, they send updates via text to confirm your appointment date and how far out they are before arrival. I also appreciate the fact they're a NH based business. See? Not all my money has to go to Mass. Needless to say....I have them bookmarked for any future plumbing needs (Re: I'll need a bidet installed in my bathroom soon). I highly recommend giving these guys a try. St Pierre Plumbing & Drain Cleaning is worth 5 leak free kitchen sink water traps out of 5.
