"My old boiler was 53 years old! On its last legs. I got In town plumbings number from a neighbor who had her boiler installed by them. I called and the next day Guy was in my home assessing my situation. The next day I had a reasonable quote and the next week he was ordering my new boiler. He installed a new boiler and water tank in a day and a half! With his two employeesâ ¦.Frank and Carl. All these guys are amazing. Full disclosure I am a pain in the behind retired police officer. I ask all the silly questions. And Guy answered them all. This experience with our new boiler could not have gone better. I could go on and on. I highly recommend them for any plumbing situation."

"Steven was the absolute best… arrived at the very start of only a two hour window, fixed the problem in about an hour. Very polite and courteous. I called three plumbers and he was the first to call me back and the only one who would give me a ballpark figure over the phone. The others wanted to come out and have a look for $70. even though I accurately described the job in detail. I’m thrilled to have a reliable plumber! A more than satisfied customer, Lora Harrigan"

"Jimmy Nilaj and his team are the contractors we have ever worked with. He started by gut renovating my parents’ apartment for us and we have heavily leaned on him on the work needed in our almost 100 year old house. He is completely honest, thoughtful, patient and always willing to talk you through the project. The work is always delivered on time and with the care of an individual that not only stands by their work, but also treats the job as it were for his own home. You could not do any better than Jimmy - thank you!"

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