"Barbara installed a new kitchen faucet and strainer plus had to make some changes under the sink with pipes/connections. (Just had new sink and countertops installed) We have used Barnagat Plumbing several times. She listens when you tell her the problem and then offers options - some times only an adjustment is needed and not a total replacement. We are 100% satisfied with her work and appreciate her honesty when it comes to providing options for fixing a plumbing problem."

"As always, it went very well. A message left with the home office was answered quickly and an appointment made to review various options. The sink was put on order and the job was completed in less than 1 week. Tim was polite, professional, precise with both the measurements and the installation of the new sink and willingly explained each step in the process. Mako has been my go-to plumbing company for many years. I have always been happy with both their professionalism and quality of work. I have referred several friends all of whom have been equally pleased with their work and would not hesitate to recommend to others."

"I had an excellent experience with Hakim from Haque Plumbing. I found him through Angi, and he was the first to respond to my service request. He arrived promptly, quickly diagnosed the problem, and clearly explained what needed to be done. One of my plumbing valve handles had broken, leaving me without water. Hakim repaired it efficiently and made sure everything was working properly before he left. He also fixed an issue with my outdoor hose connection that wasn't working correctly. Hakim was professional, knowledgeable, courteous, and took pride in his work. It's not easy to find someone who responds quickly and provides such quality service. I highly recommend Haque Plumbing and will definitely call them again for any future plumbing needs."

"My kitchen sink in the store I managed in Tribeca was constantly getting clogged and would leak all of the time. The pipe under the sink was so old and eaten away that when he began to remove it, it broke away instead. He got us a replacement and fixed the sink and even repaired our toilet that would also clog occasionally free of charge. I?d hire him again."

"I can not say enough about Egli plumbing. Finding a good plumber is like striking gold. And the definition of a good plumbing company in my mind is someone that thoroughly inspects the situation, takes there time with the estimate, thoroughly explains the damage with what is needed for repair or replace, and gives a honest estimate for the work. Then lastly follows through with good work. Egli plumbing is 5 stars across the board. They took the time to not only evaluate the issue but stayed until the job was done right. We took on major damage to our main sewer line in the basement. They did a full replacement, installed new traps, and put in check valves to prevent further flooding issues. Our situation was dyer and they never once tried to take advantage of our situation with price gouging or doing un necessary work. We will be using Egli plumbing for all future projects, as well as calling on them annually for maintenance checks."

FAQs for plumbing installation for a remodel or addition projects in Flushing, NY

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.
