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)

"DMV were the contractors for a series of renovation projects in my home -- renovate a powder room, complete renovation of the kitchen, renovate a closet space, install a skylight, repaint several rooms and the staircase, and refinish the floors upstairs. Javier and the crew were outstanding: very communicative throughout the project, attentive to my concerns and the integrity of the house, and very accommodating with my neighbors. Javier offered many helpful suggestions for tiling, fixtures, and colors. I'm thrilled with the results -- the quality and precision of the work is excellent, and the skylight has transformed my home and my life. Perhaps the most amazing aspect of the project is that I could not be on site as I was posted overseas during the work. I had to trust Javier and his team completely to carry out the work without my hands-on presence. My trust was well-placed. They took care of my home and its contents, and the project was finished in budget and early. Javier was also super-responsive and helpful once I was able to return home. I can't recommend DMV highly enough! S. Boswell"

"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."

FAQs for plumbing installation for a remodel or addition projects in Gaithersburg, MD

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.
