"Chris and his co-worker were very good. My hot water heater was in a very tight space. With that being said they did a nice job on the sodering. Chris replaced a valve he didn’t like. They did a great job cleaning up. Once installed and powered up they waited outside for 30 minutes to make sure the water got hot."

"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"

"They came out on a weekend and we're our saving grace during one of the most frustrating experiences we've had in this house. We couldn't use any plumbing without flooding the basement with sewage, it was early stay at home days, and we felt like we would go mad. They showed up and gave us an price for replacing the broken pipe, and set in to work. They worked for the entire weekend essentially, staying extremely late at night and showing up early the next morning, and at one point driving far out at night to get supplies since their usual local place was closed (again, quarantine time) . The reason it took so long was because after opening up the floor to get to the end of the pipe to replace it they found more damaged pipes, and replaced those as well. By the end of it they had spent the entire weekend on a job they expected to only last an afternoon, had charged us not nearly enough for the amount of work they did, and fixed a leaking bidet we had for free for good measure. They also advised us to do camera scan to look for any other problems, which they couldn't do until the water drained out, and even did an initial mop of the basement (which, remember, sewage flooding). I'm honestly half convinced these people are magic helpful brownies or something, it's unreal how helpful they were! Somehow our drier which has not succeeded in drying clothes for over a year has started working in a single cycle since they left, despite the fact they didn't even do anything with it, and in fact specifically said they don't do driers and offered to recommend someone else when we mentioned it. Suffice to say, I cannot recommend them highly enough"

"Rich is amazing. He shows up when he says he will. He is versatile and can do just about anything. For me: flooring; tile work; painting; kitchen closets; granite countertops; lighting and other work all done very well with attention to detail. An added bonus: he makes good suggestions and will even meet you at the store to pick out materials. I have referred him to others and they were all very happy with his work, his professionalism and his reasonable prices. A pleasure to work with."

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