"The original project I hired them for was to replace leaky faucets in both the kitchen and bathroom. Frank, the owner, was responsive and professional. They scheduled the work promptly and showed up on time. Unexpected issues were discovered that required a second trip and additional work. They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."

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 plumbing installation for a remodel or addition projects in Round Hill, VA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
