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.

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.

I live in College Park, and I knew that my water (municipal water) was leaving gross scale on our…read morebathroom fixtures and was therefore hard water. I also noticed that our water smelled very heavily of chlorine. I wanted to hire a company to soften our water and install a reverse osmosis drinking water system, but I honestly didn't know where to start. Something like 20 years ago in a different state we had purchased a Culligan water softener system, so I started my quest to look into water softener companies by calling Culligan. I am a member of Costco, so I also called Costco's water treatment folks, who happen to be Carroll Water in my area (who sell EcoWater systems). Both the Culligan and the Carroll Water systems seemed nearly identical; both use electricity, have electric timers for their salt water washes that you have to pre-set and worry about re-setting if the electricity goes out, are rather large systems, etc. One was a bit more expensive than the other (it actually annoyed me to no end that EcoWater/Carroll Water/Costco have some kind of buy-a-water-system-get-a-HUGE-Costco-gift-card thing going on...just seems way too gimmicky). My father, an engineer with tons of patents, lives in another state and had purchased a Kinetico water softener system and loved it. He told me I really needed to try to find a Kinetico dealer in my area so I could take a look at them, also. So I found Mermaid Water. I was impressed that their system didn't use electricity and that the salt water backwash system kicked in because of usage and not because of electric programming. To me, this seemed much more efficient than having a system that just always backwashed on Sundays at 3 am or whatever. The Mermaid Water representative who came to my house initially (Ed Owens) was also very flexible about the installation process - far FAR more than the Culligan or Carroll Water folks. I also LOVED that the Kinetico system was so much smaller and had such a smaller footprint than the Culligan or EcoWater systems, for we were limited on space. Even though Kinetico/Mermaid was a bit more expensive than Culligan and Carroll Water, I chose them. I'm very glad I did, but I didn't really understand why until after I had the installation team come in with our new equipment. The Kinetico installation team was absolutely amazing. Truly. Brad King, the son of the owner, did the install, and he is absolutely a master plumber. No one could have done a better job. He came into my house, created phenomenal ways to get the job done while minimizing the footprint of the machines and maximizing the benefit to my house - I am so grateful to him. And as he did the install, I asked him a thousand questions and he was SO patient and answered them all. And it was during this time that I became much more educated about the equipment and so grateful that I had chosen to purchase it rather than anything else. For example, I watched while Brad set the clockwork discs/gears that tick down to when the softener enters a backwash cycle. Basically what happens is that as you use water, the machine slowly ticks down via a small clocklike gear until it's time to start a backwash cycle. Then one part of the machine backwashes while the other is still filtering your water. The cool thing is that the Kinetico equipment actually backwashes itself with treated water (the others don't), which lengthens the life of your equipment. And since only one side of the water softener (there are two sides - basically two water softener units that sit side by side) regenerates/backwashes at a time, the other side is always still filtering your water. Whereas with Culligan or EcoWater, their machines don't do this - the whole setup backwashes all at one time, leaving untreated water coming into your house. Also, because usage is measured via a mechanical clockwork gear and not an electrical panel in the Kinetico systems, there are less electrical parts that can fail in the future, and you don't need an electrical outlet nearby to plug the machines into (which made me happy - I didn't have to get an electrician out to run wiring for a new plug). The Kinetico system typically backwashes more frequently than the other systems, since it backwashes based on usage, leaving me to surmise that you could absolutely be put in a position with units that only do this based on timers where your system is gunky and needs to backwash but hasn't yet done so because the timer hasn't told it to. And the Kinetico system uses far, FAR less salt during backwashes, thus FAR less salt overall. I would much rather have equipment that backwashes when it knows it needs to based on its own usage than a system that backwashes once a week based on a timer. Their reverse osmosis system is also stellar; it has powerful water pressure - much better than other RO systems. We are THRILLED with our Kinetico equipment and THRILLED with Mermaid Water! The best brand of equipment out there.

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.
