"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."

" I had A&M service my On Demand hot water heater. He did a great job. I decided to have additional work done. I have an older home and decided to have some old valves and pipes replaced. I would definitely recommend A&M"

"This is the second time we have used Bill. On both occasions, Bill was friendly, professional, since my son and I aren't really plumbing friendly, he was very thorough when explaining everything he was doing. Bill gave us different cost-efficient options, told us which he thought would be the best way to go. If you are looking for a plumber who knows what he is doing and is also trying to help the customer save money as well, Pipe Doctor Plumbing is the way to go. After our experiences with Bill, how honest and knowledgeable he is, and how once his work is complete, we have NEVER had to call him back to fix something he had already fixed, I do not think I would ever be comfortable with trusting another plumber after Bill. I have had my own home for many, many years and have dealt with many contractors, electricians, and plumbers and I have never felt comfortable like I do with Pipe Doctor and listen to his advice. I also have never let any workers in my home do any work while I was not present and that says ALOT. I would recommend Pipe Doctor Plumbing to anyone in need of a Plumber. FIVE STAR RATING"

"They arrived on time, removed the old water heater and installed the new water heater. They reworked some plumbing to have the water lines connect to the new heater. Cleaned up all sweated joints, cleaned up the floor where the work was performed and then made sure everything was working. I would definitely call them for future plumbing work."

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