"Great experience. Tawn was excellent - he knew what he was doing, got the sump pump removed, cleaned out the sump, repaired a pipe, then installed a new pump. Very happy, will definitely call Tawn back for any future plumbing needs!"

"A+++++ Service. 5 Stars for sure. You should definitely check them out. I am so glad I've taken my time to find good, honest, trustable and fair plumbing company, and I finally found this R-Plumber company. A few months ago, my place had a water leak in the shower on upstairs bathroom and it caused ceiling damage, etc. so I needed to a ceiling drywall repair, bathroom tile repair, CPVC pipes reconnect, water pressure reducer install, etc. I took my time to compare various popular local plumbing companies in the DMV area and this is, by far, the best I've found due to many reasons: 1. They are licensed, bond, and insured -- They sent me a copy of their license, bond, insurance, and worker compensation. This gave me a relief because I wanted to make sure I hire a professional. You'll need it in case if anything happens. 2. They really care about you and HONEST -- Rene, Luis, his apprentice, and other staff use the best brand and told ,e really honest and professional opinion. I have a limited budget and they told me I can just fix the issue for now. The other companies recommended me to remodel the whole bathroom, which would cost at least $4,000 or much more. 3. Their price is VERY REASONABLE and FAIR -- They do not overcharge at all in compare to other companies in this area. I compared 6 other plumbing companies. Other plumbing companies seem to take advantage of you especially if you don't really know much about plumbing. They either: - could only offer to fix the plumbing and I had to find my other contractor to repair the tiles and dry wall - offer me to fix this issue for $4,500 or more - R Plumber offer me about 40-50% less than other companies. - another well known company (they were featured in local Costco) gave me a price to fix my sink popup assembly for about $700 but I went to home depot and bought the parts myself for $17. 4. They really guarantee that they carry their work by the correct local regulations and to the high standard. -- you can see the photos for reference. - I ASKED them a lot of questions and researched the way they do they work online and everything seems to be done very correctly (e.g., using the right glue, chemical for connecting my CPVC pipes, copper pipes) - They went above and beyond in installing my water pressure reducing pipe by anchoring my water supply pipes so it doesn't get shaky. - They have 1 year labor warranty. Their shower MOAN is lifetime warranty on parts. In fact, I am so impressed that I literary have to write my appreciation on various social media in a hope to help others who are in the same situation as me. This company doesn't spend on marketing but just spend on high quality so I'm really trying to help get this company to top review to help others who are in the same boat. Best wishes to you guys who are looking for a good plumbing company. This is some company you should consider."

"Rema was very thorough when installing my new kitchen faucet. He came to my home at 6:15pm, which surprised me. In my experience, it’s difficult to get a plumber past 5pm! My faucet works perfectly and he was very nice. He said he has been doing plumbing for 20 years! I think I have found my “go to” plumber!"

"We hired Kozan Construction to do some major plumbing construction work moving the plumbing for a washing machine and utility sink and reworking the plumbing for a bathroom sink. They provided a fair bid and so we hired them and were told the project would take a week. Faruk was respectful and hard-working and would accommodate all of our requests to have pipes or the levers moved and straightened. Our main issue was scheduling, as he had a number of other plumbing emergencies that delayed our project and left us without laundry for two weeks. The work was good and done all up to code, so if you have some flexibility with your timeframe, or it s a emergency call then I definitely recommend. If not, just make sure you work out a schedule ahead of time so you know what to expect."

"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."

"I contacted Mr. Jackson and he promptly responded to my residence to assess the condition of my old water heater that stopped working. Mr. Jackson took the time to explain to me in detail, my options to repair my current water heater or purchase a new water heater. I decided to replace my old water heater with a professional grade water heater Mr. Jackson had recommended. Mr. Jackson procured my new water heater on Columbus Day and installed it the same day in compliance with local codes for water heaters. Mr. Jackson followed up with me via telephone to make sure my new water heater was functioning to my satisfaction. My response was indeed it is! Mr. Jackson was a true professional and took his time to ensure my installation was performed correctly, a job well done."

"First I would like to say I would NOT HESITATE to hire Miracle Method Surface Restoration from Kensington, MD again. The office receptionist (Margaret) and the two gentlemen that did the cut out and install (Carlos and Luis) were EXCELLENT and I would rate them an "A" in all aspects of their roles in the company. The C responsiveness and C Punctuality related to the following: (1) a prearranged appointment resulted in a no show by the company head (this is not our residence); and (2) the representative that did come the next day did not have any photos of previous work or paperwork to move the project ahead. If it wasn't for Margret in the front office we would not have used this company; however, she went out of her way to get a photo of a cut out, ensured that the proposal was revised for details, and scheduled the work. Like I said in the beginning, I would gladly hire and recommend this company. Just be sure to confirm appointments."

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