"Chris G and John did an excellent job! DB’s Plumbing and Drain is an outstanding company. This job may seem a bit expensive but I ordered 2 higher end toilets and they had to deliver, install, and haul away old toilets. I have also hired them in the past to fix my water heater. All the technicians I’ve met are very professional and punctual! I will definitely hire for any future work!"

"The boys at R Plumber came in on short notice and took care of a messy gas rerouting line I was dealing with. Before others had even responded to my inquiry, these guys were finished with the job. Later on when Best Buy dripped the ball and couldn t install my gas range, the owner of R Plumbing Rene himself came and did it in less than an hours notice. I highly recommend this company and I am glad I hired them. Professional and experienced and great price for the job. G.T."

"OK, so Mr. Frank was very professional. All his team was very professional, very polite. They were on time and they went far and beyond of what they were supposed to do and did not charge me more than what they said, so I am very very very satisfied with the work that Frank did, and I wanted to thank him team for being so wonderful and such a great People, we don’t get that anymore in America, but he definitely gave me that. And I’m so happy that I hired him. I had five different people that I got proposals from, and I called all of them multiple times to check on things. And definitely Frank. He definitely made this right. So if anybody needs a Plumber, that’s the guy needs to be hired once again. Thank you very much for all your services. And I recommend Frank to anyone that needs plumbing work done Thank You,"

"Review for 10-19-20 Silver Spring, Md. home I called Douglas & Son Plumbing to replace an old frost free outdoor faucet. Shawn Douglas plumber installed the new frost free exterior faucet that was twelve inches long and inside my house installed a shut off valve; furthermore, the plumbing code recommended. He neatly cut a small square box in the panel in the Den to find the pipe. After he found the pipe he installed a shut off valve for the frost free exterior faucet. His measurement was exactly correct to find the hidden pipe behind the outdoor wall. He explained that the exterior faucet should have a separate shut off valve. He had great rapport with the customer that is me and I was impressed that he used a lever to balance the frost free exterior faucet. I do not about any customer that was not satisfied with his work but he receive a five star rating for this job."

"Juan Carlos came out and was very professional. He called before arrival and explained everything he saw that was wrong. When he installed the water line he noticed some more problems and showed me. He recommended how to fix them an then we proceeded. He was decently priced and honest. I recommend him to anyone. We have found our plumber!"

"What a great experience! Scheduling was a breeze; and the plumber, Owen, arrived on time, well within the window after a call that he was on his way. I originally scheduled them to install a touchless kitchen faucet I had purchased; when he was here, I inquired about replacing the garbage disposal and then he noted some issues with my current kitchen sink traps (which were clear to see when he pointed them out). Owen was friendly, knowledgeable, and professional; and he immediately flexed from my initial faucet installation request to add the other two items to the scope. Overall, I couldn't be more pleased with the service... Owen did a great job and I'll definitely reach back out to The Pipe Doctor for future plumbing needs!"

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