"RightNow Plumbing reliably provides competent, scrupulous, trustworthy service. Recently I engaged Andy to service our well-water acid neutralizer tank, because I questioned the reliability of service by another company 13 months earlier. Andy tested our water and found that its pH value was 6.97, which was consistent with previous readings over the past six months when he did other work for us. Because our well-water pH is essentially neutral, Andy explained the acid neutralizer tank is not necessary. He offered two options: 1) remove the tank (thus leaving us with only the water softener tank) or 2) empty it, which option I selected. He also reduced the cost of the service call. Andy’s approach starkly contrasts with the other company that for years took advantage of an unsuspecting customer by charging almost $300 to “service” the tank and unnecessarily adding expensive calcite. For competent, scrupulous, trustworthy service, call RightNow Plumbing. Posted May 14, 2025"

Here at Best Homes, our company is based on the belief that our customers' satisfaction is of the utmost importance. Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez

"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

"I just had Potts Brothers redo my bathroom and basement, and honestly, they killed it. The whole process was super easy, and the results are amazing. Youssef and Peter were awesome to work with. Youssef helped me figure out the design and had some great ideas that made everything look even better than I imagined. Peter oversaw the work and together with omar and the rest of the team, and they made sure everything was done right and on time. The bathroom is now my favorite part of the house—it’s modern, functional, and just looks so good. The basement went from being a storage dump to a space I actually want to hang out in. The quality of the work is really solid, and you can tell they care about the little details. What I really appreciated was how communicative they were. Youssef and Peter kept me in the loop the whole time, answered all my random questions, and made sure I was happy with how things were going. If you’re thinking about a remodel, I’d definitely recommend Potts Brothers. Youssef and Peter are a great team, and they made the whole thing stress-free. 10/10!"

DMV Kitchen and Bath Inc is a family owned and operated Full Service General Contractor specializing in Kitchen & Bathroom Remodeling and Design/Build Services. We ensure a high quality finished product with flexible and attentive service at a competitive price. We pride ourselves on having the ability to make our clients visions come to life with great design ideas and execution. Showrooms: Chantilly, (VA) (703) 657-0997 and Gaithersburg, (MD)

"Awful, awful experience. A true nightmare. They charged tens of thousands of dollars and messed up basically every aspect of our bathroom remodel. Given multiple opportunities to fix their problems, they did not. Extremely sloppy, low quality work. The work on the bathroom was clearly done by someone who has never seen a bathroom or used one, much less built one before. The shower leaks, the tile was so crooked and bumpy it had to be ripped out twice, the radiators were badly reinstalled and dripped water down through the floors into to kitchen below, the walls and ceilings they built are not straight or square, the sink handles immediately fell off, they caused a $1000 plumbing clog and our basement to flood with sewage by flushing construction debris down our toilet. Instead of replacing pipes, they kept the old pipe which we had asked them to replace, and then tried to hide and cover it up. They would also show up unannounced and let themselves into our home on days when they had not told us they would be coming or that we were supposed to expect anyone to be in our house. So on multiple occasions I would hear an unexpected noise and I'd look over and see someone in my house who I had never seen before in my life. And every time we raised an issue to them, they either ghosted us or tried to convince us it was fine and that their work had been done correctly. I have pictures to document all of these issues. I will never let anyone from DMV enter my house again and I will tell everyone I can to never do business with this company. Scammers, liars, incompetent, I hope they go out of business."

FAQs for tankless water heater installation projects in Round Hill, VA

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
