"We had our master and hall baths completely gutted and rebuilt. We bid the project out to several companies, and DMV was immediately the most helpful. Pricing was very competitive. Luis and the team completed both bathrooms in about 6 weeks - and this was a full demo. The crew was extremely kind and courteous, and worked hard to minimize the mess and impact to our home. One weekend we had a party, and they helped make our home look like there wasn’t a major project in-progress! Craftsmanship was impeccable. The tile work in particular is beautiful - details I hadn’t even thought of were done for me. Like any job, we had some changes to scope (our choice), and some minor hiccups. They were extremely helpful navigating through scope changes, and more than fair on pricing. And on the minor hiccups, they made it extra clear that the job wouldn’t be wrapped until we were satisfied - and that’s what happened. Honestly this experience was a 10 out of 10, and I hope we can have them out for another project soon. Our bathrooms went from blight to bling in 6 weeks - I look forward to getting ready now!"

"Extremely disappointed with this company. They do not stand by their guarantees. Did install shower in one day. Was not provided with the shower head I ordered. Calking and trim work was very sloppy. Went through the shower wall into my bedroom, did sparkle wall and left it. Shower doors have leaked and was finally told six months later that there is nothing they can do to correct the issue. Originally quoted $24,000.00 for the walk on shower, eventually agreed to $11,500.00. Completely dissatisfied with my shower. Once they get their payment, they are done."

FAQs for plumbing installation for a remodel or addition projects in Rockville, 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.
