"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..."

"We were getting very frustrated about trying to get someone to fix this toilet. A similar repair some years ago cost about $150,
but the new super in our building said this repair would cost about $400! We considered it....then logged on to Angie?s List.
Rapid Repairs referred us to a plumber near to us and he arrived that afternoon. He assessed the problem, left to buy the needed part and fixed the toilet when he returned. The bill: $160.
We were so grateful for the speedy, efficient help we got and highly recommend this company.

"Ty Salazar is a nice guy, very knowledgeable, and a great kitchen designer. The work that eventually got done was of high quality, and his people were very responsive to our requests. The problem was in the scheduling and timing. Essentially, Ty seemed to lose touch with the project about halfway through, and that's where it all went south. We had timed everything so that the work would get done over the summer and we'd have a functional (if not 100% complete) kitchen by Labor Day, after which the kids would be back in school and we needed a working kitchen. I asked about this repeatedly and was repeatedly told that this would happen. I pushed hard to get all of the materials and appliances ordered so that they would be delivered on time. Well, we went away for 2 weeks before Labor Day, and when we got back, the work was nowhere near complete -- yet I was invoiced for the completion of the project. Several times I asked for a project schedule, not once was I given one. I gather that part of the problem was that we had to have permits for plumbing and electrical work and the "prima donna" behavior of the licensed plumber and electrician, who didn't show up when they were supposed to, left jobs uncompleted, etc. At any rate, we didn't have a working kitchen until late September, and the finishing cosmetic work took another few weeks to finish up. The final piece of the puzzle, a shelf that had to be custom made for a corner base cabinet, wasn't ready until January, and I got so tired of waiting for it to be delivered that I went out to Forest Hills myself to pick it up. No question about it, we love the new kitchen. But I was really not happy with the timeliness or the lack of communication over the scheduling."

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.
