"My son owns a rental property in Old Bridge NJ. Although he had it inspected prior to purchase there were a few plumbing issues left behind. In his efforts to repair those issues promptly and correctly, he hired MrFixit CNJ Home Service located in Manalapan, NJ. Rob at MrFixit was very helpful and sent a technician. In the end everything was done properly, fairly and even included a discount! We are very pleased with the great service and fair pricing! Services: Find & repair leak, Repair toilet"

"While looking for a plumber to inspect and replace a leaking water heater, I found Rapid Repairs.  I called the number, and was directed to send a text message if I needed a emergent response.  After only a few minutes, I got a response in a text message addressing my issue.  They were professional and answered my questions as best he could without being at my house.  I even got estimates based on my answers.  The only reason I did not utilize their service was that I needed hot water immediately, and they were already on multiple service calls, meaning the earliest they could come out would be Monday.  
I would definitely use them in the future, I was very happy with the response and appreciated that he was polite and understood that I couldn't wait for them to become available.

My husband and I just bought a new house and in the basement the washer, dryer and utility sink were all in different locations in the basement so this is something we wanted to fix before purchasing new machines and moving in. Since we have an unfinished basement all of the pipes are exposed so we thought it would help make the job a bit easier to do. Even though we played a bit of phone tag with Rob in the beginning he was able to come out and give us a fair estimate. He showed up on time and was very friendly, with a big smile on his face. We knew this is someone who enjoys what they do. We talked through different options and it was clear he wasn't trying to over sell us on work we didn't need. He was trying to come up with the most cost effective way of getting done what we were looking for. He was able to write up an estimate while he was at the house which was way faster than anyone else. Other plumbers we have to wait almost 2 weeks for the estimate back. He was very reasonably priced and came in right where our budget was and what we thought it might cost so we hired him.

He was not able to come out the day it was scheduled because we had some bad weather and there were other plumbing emergencies in the area and since ours wasn't an emergency, we understood. But he was able to come the next day which was just in time for our new machines to be delivered. He showed up on time, was again very professional and friendly. He got the job done in the time quoted and we were very pleased with the results. His work was very clean and he walked me through everything he did when it was all done.

This is someone I would definitely hire again in the future and would recommend to anyone.

FAQs for plumbing installation for a remodel or addition projects in Neptune, NJ

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.
