We compared it against the distilled water that we had and the results were appalling. Installation was scheduled and their technician Adam Marjason completed the installation in less than 2 hrs.

He answered all our questions post installation and practically went through the dos and the don'ts of the system. I will update this review in an event of any issues (if any) and how it was handled. But until then, overall we have good experience right from the start.

But our most recent experience reminded us why we trust this company so much. On a Saturday night around 8 p.m., we discovered a leak on our main level--every homeowner's nightmare. I was terrified we wouldn't get help until the next morning. Instead, dispatch quickly sent Eric, a capable, kind, and highly skilled plumber. He was thorough in finding the source of the leak and stopping it, and he did so with a calm professionalism that instantly put us at ease. I've been a fan of Marine Plumbing for years, but I have no words for how much it meant to have a well-qualified person show up exactly when we needed help the most. Their reliability, expertise, and genuine care for their customers continue to set them apart. Highly recommend.

Chuck has a lot of experience in water systems and I highly recommend Nova Water. I will certainly use them again in the future whenever needed.

I had a plumbing issue that was starting to stress me out, and from the first phone call, I felt like I was dealing with professionals who genuinely cared about helping -- not just booking another job. They responded quickly and showed up right on time, which already put them ahead of a lot of contractors I've dealt with before. The technician was respectful, knowledgeable, and took the time to actually explain what was going on instead of just throwing out technical terms. I really appreciated that. It made me feel informed and confident about the repair. What stood out most to me was the honesty. There was no pressure to upsell anything unnecessary. They focused on fixing the actual problem and making sure it wouldn't turn into something bigger down the road. The pricing was clear and fair, and there were no surprise charges at the end. The work itself was done efficiently and with obvious attention to detail. Everything was cleaned up afterward, and you honestly wouldn't even know work had been done -- except that the issue was completely resolved. It's hard to find reliable service companies these days, but Crown Plumber exceeded my expectations. If you're in Ashburn and need plumbing work done right the first time, I wouldn't hesitate to call them again. Definitely five-star service in my book.

We have had two experiences with Crown Plumber and the latest was so exceptional I wanted to…read moredocument it here. We had a leak in our basement and believed it to be caused by a toilet leaking. A plumber came (not Crown) and fixed the toilet but the drip persisted. When I tried to call this unnamed plumber back, he said he was out of town for a week. Ugh! Crown to the rescue! I called crown and they sent Elvis over to explore our problem. Elvis quickly determined that the toilet was not our problem and set about exploring other options. After some good detective work, he discovered a very slow leak inside one of our walls. He expeditiously fixed it and explained the cause. This guy knows his business! We also appreciated his being upfront about the cost of his visit had was careful to document the itemized bill. He even carried a book of possible repairs and their cost for transparency. It is hard to find a good plumber but I have high praise for Crown and recommend them without hesitation.

What an amazing experience with Mark from Lyons!…read more 5+ stars for service, quality, and value. My husband asked several plumbers for quotes, and Mark was the first to reply, right away. He gave us a fair estimate based on the problem description and scheduled a visit immediately. True to his word, he quoted the exact cost when he arrived. During his first visit, Mark was thorough, answered every question, and explained everything clearly. He fixed half the issue on the spot and returned the next day to finish the job. Because the old valve was badly installed and the surrounding "box" cracked when it was removed, Mark went above and beyond. He replaced the whole box and the new valves, a service that would normally cost an extra$200, but he didn't charge us a cent for it. He tested everything before leaving, and when I mentioned our weak‑pressure shower, he instantly diagnosed the cause, explained what caused it, and showed me the issue, and fixed it at no additional cost. I also asked about the slow draining sink, and Mark handed me a tool to remove the debris and showed me how to access the clog. Again, this was free of charge. Mark assured us that Lyons' labor and parts come with a one‑year warranty and that the components used are built to last. In today's world, it's hard to trust someone you don't know, but Mark made us feel completely comfortable and at ease. We're thrilled with the service and will gladly refer Mark and Lyons to anyone needing plumbing or drainage help! We will no longer be looking for another plumber again.
