"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."

Our project, which was completed in January 2025, consisted of a complete remodel of two full bathrooms which were vintage 1983. Amanda was our designer, Mark was the lead installer, and John was the project manager. All three of them provided welcome suggestions, good guidance and advice throughout the process… starting with clear and transparent service agreements. Select was very accommodating with scheduling and access to the house / workspaces. Questions were answered promptly by Amanda, Mark and John, and any concerns were addressed to our satisfaction.

"We were 100% satisfied with Washingtonian and with their work building our addition and deck. Not only was the workmanship and quality of the construction outstanding, but they operated with honesty and integrity. Their goal was our satisfaction and building a quality addition and deck. They accomplished all three and were reliable, dependable and conscientious. At no time did we believe that they had over-committed or were unable to deliver on what they had promised. They never cut corners to rush to another job nor did I ever feel that they were not spending the necessary time to ensure that the work on our job was thorough and complete. Travis, Kris and their crew were 100% professional, communicative and transparent. We will be using Washingtonian again, without hesitation. Our experience was excellent and they did an awesome job."

In addition, we help you with design, planning, permit, and construction process. We take great pride in our top-notch remodeling services in Rockville and ensure that every project we do turns out perfectly.

"Our place had good bones but didn’t work for our daily life. Every room felt cut off from the next. Ben and Teddy from Top Remodeling sat with us and came up with a better layout without changing the size of the home. They moved the hallway, opened the living area, and added a custom touch in almost every room. They rebuilt the inside from the studs and used solid-core doors and clean finishes. We went with soft white walls, bronze handles, and natural maple cabinets. Now, it all feels open and calm. Every room has a purpose."

"DMV Kitchen and Bath just finished the second project at our home. The first in late 2022 was a major upgrade and enlargement of a primary bathroom and creation of a walk-in closet. We love it and it turned out gorgeous. The second project was finished in November 2024 and the results are even better. We needed to repair a room in the basement that had had water damage. We decided to include a variety of other updates for our home at the same time. DMV worked closely with us to bring our vision into existence. In the basement we now have a new fourth bedroom, including 2 large new closets along with new lighting, paint and doors in other rooms on that level. The large laundry room was gutted with new kitchen cabinets and pantries installed along with new lighting. The other 2 bathrooms in the house were upgraded to the same vanities and cabinets as the primary bathroom. Javier provided great assistance helping us with the design, selection of materials, and practicality of various ideas and solutions. David, as leader of the construction crew, was exceptionally good at communicating with us and coordinating and supervising all of the workers involved in the project. David and his staff did great work. We are very pleased with the final project. We highly recommend DMV."

FAQs for plumbing installation for a remodel or addition projects in Washington DC, DC

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.
