New Reasonable price **If I could give Omni Plumbing and John 10 stars, I would.** I first met John almost 10 years ago at Home Depot. We were both looking at Halloween decorations, and somehow we started talking. What started as a quick conversation turned into almost an hour of talking about our love of decorating for Halloween, and eventually our families, spouses, children, and what we each did for a living. That’s when I found out John was a plumber. I remember really enjoying that conversation, but what stood out to me even then was the way John talked to me. As a woman, I’ve had plenty of experiences with men in traditionally male-dominated fields—plumbing, electrical, automotive, etc.—where they feel the need to “mansplain” things to me. These are subjects I’m actually pretty well-versed in, and being talked down to is something that really bothers me. John never did that. He spoke to me as an equal. He listened to what I had to say, took my thoughts seriously, and never made me feel like I didn't know what I was talking about simply because I wasn't a professional. Over the years, I've used Omni Plumbing for quite a few things. John installed my mom’s hot water heater, and he has helped me with numerous plumbing and heating issues. One experience really stands out. Almost two years ago, my boiler failed during one of the coldest weeks in January—and it happened to be my birthday weekend. Anyone who has ever lost heat in the middle of winter knows how stressful that is. John initially told me he couldn't get to it until the following week. I completely understood. I knew he was busy and that I'm certainly not his only customer. But then, **he showed up on the weekend.** He gave up part of his weekend and came out to replace my boiler so that I wouldn't have to go through the weekend without heat. I will never forget that. Another time, my downstairs level wasn't getting heat. I had a feeling I knew what the problem was. John was at another customer's house, and after a short conversation he had me send him a picture of the part I thought was bad. He told me that if he finished early, he'd stop by; otherwise, he'd come the next day. It was getting late, and I honestly thought there was no way he was still coming. But he did. And because I had sent him the picture, he already had the replacement part with him. I was right about the problem, he replaced the part, and I had heat again. These experiences are why I continue to use Omni Plumbing and why I recommend John to anyone who tells me they need a plumber. **John is knowledgeable, dependable, honest, respectful, and genuinely cares about his customers.** He doesn't make you feel like just another job on his schedule. Whether you have a planned project or you're dealing with a plumbing or heating emergency, John is the person you want to call. I've trusted him with my home, and I've trusted him with my mom's home. That says a lot. **Omni Plumbing is absolutely a five-star company, and John is the kind of plumber you hope you'll find but don't always expect to.** If you need a plumber in Cornwall and the surrounding area, **call Omni Plumbing. You won't regret it.** Services Service not listed

Jon took time to explain my tankless system, providing me details about maintenance and general function. All of it was new to me and the education helped me feel empowered. He is honest and upfront about the work needed. No sugar coating to win the business. He is knowledgeable about his trade and offers an expansive network beyond plumbing. I appreciate being able to support a small business and a family. Especially a small business with such credibility.

Jon helped me out with a plumbing problem I was having recently and I would recommend him to everyone. He'll help you out with what you need rather than try to sell you more services. - much appreciated

In the period of one month, we endured plumbing, auto, and lead plaster issues. The plumbing issue proved to be the most daunting of the three. There were moments, which we didn’t know the way ahead, with regards to the plumbing. Out of nowhere, Jon came to the rescue and immediately addressed all of our plumbing issues. His professionalism, talent, and attention to detail are unmatched; furthermore, Jon treated our problem, as if it occurred in his own home. Take down his number and call him for your plumbing needs. He is fast to respond and supports Veterans. He is simply the best. C&R B. Services Plumbing pipe repair, Sewer repair

Amazing, detail oriented and quality service. I had 3 licensed and supposedly legitimate companies come to look at a toilet that would not work. They were all telling me that I needed to tear out a newly tiled floor, that it was a trap problem. I called Omni. After asking me some questions, Jon diagnosed the problem correctly over the phone! Not only was he correct, but he addressed a problem that had been an issue for years and that other plumbers had never caught. The problem was not even under my floor, so the other guys would have wreaked my floor for no reason.Since then, I've called Omni for other issues, including an emergency. Excellent service every single time.

Jon of Omni Plumbing helped me out of a jam! My under-mount sink fell out of its bracket mounts and compressed all the plumbing beneath the kitchen sink. I was able to reattach the sink, but the trap and drain still leaked. Jon came over and instead of overcharging me for a new trap, simply replaced the gaskets and saved me the cost of the trap. That was very honest of him, he could have taken advantage of my limited plumbing knowledge.
