"I have had several projects completed by Jakob and his company since buying my home in 2017. From little jobs to big jobs, Jakob is the only person I will trust with my home projects. His crew is reliable and hardworking. Jakob is hands on about EVERYTHING. From material orders placed, to deliveries, to getting permits, to scheduling inspections, to coordinating his crew for different jobs….. I honestly don’t know how he keeps it all running so smoothly. He built us a BEAUTIFUL paver/deck patio a few years ago, and this year he built us a STUNNING covered porch/portico with paver walkway which matches the backyard aesthetic. My neighbors have stopped to tell me how beautiful it is and they couldn’t believe how quickly it was finished. I very much appreciate how Jakob works with me to plan and make my vision come to life. He does the job well, and doesn’t cut corners. I feel confident and secure in his work, which is why he is the only person I will call when I need something done. "

"The repair to my leaking toilet was fixed well enough, after telling me my relatively new toilet water shutoff valve was broken and would need to be replaced for an extra $100. Foolishly, I did not verify this for myself. Afterward, when I was summoned to inspect the repaired toilet, I was told my toilet tank float valve that shuts off the water inside the toilet tank once it fills was broken, and that it would cost me another $50 to fix. It was NOT broken prior to his arrival. He left and said he'd contact me later that evening to arrange for a return visit to fix it. In the meantime, I found the top cap loose and tightened it. Then flushed the toilet 4 times, each time observing that the float worked as designed and the water that fills the tank shut off properly at the designated level. It has worked great ever since. He did not contact me later that night but the next day, when I told him I fixed my own shut-off valve for free, and would not need his services."

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