"I called the number. The person confirmed the appointment. The plumber was at the location at the precise time, inspected. Called me for the expected expense, we agreed over the phone. He got paid via Visa card and did the job. All done so professionally. Can't get better. I think he was little high in price but because its 5 degree F outside, its OK for one job."

"The service from Alliance Service Pros was fantastic! Tom Kensinger was my service pro and he delivered above and beyond my expectations. The flower bed in front of my house next to the foudation was very soggy and water was coming through the foundation into my house; assumed a water or sewer leak. Chalres from Alliance pros investigated the situation, throughouly examined the situation, checked all township/state codes and then provided a compeitive quote. Two days later Tom was onsite for the repair, it was around 90-95 degrees. He hand dug 6 ft of earth to uncover a broken water line in the foundation. Tom overcame serveral challenges with main water line shutoff not working, significant flooding while digging to get the job down. He also brought a change of clothes, before coming into the house to not muddy up my house/basement. He repaired the waterline outside and through the house and then sealed the water line and the sewer line in the foundation in and out. He took care on digging to separate the mulch and dirt, so upon refilling the hole he could leave it as he left. Lastly, he hosed down all areas of my porch, driveway and sidewalk. Basically looked liked it was never touched. He worked 12 hours and promised to not leave until we had water that night. I have never seen this dedication from a trade professional before and my long review is a return in kind for the level of work he showed my family. They will be my go to plumbing professionals from now on."

"Joe is the excellent plumber! He figured out smart plumbing system for my bathroom remodel, set up stand alone faucet, hooked up jacuzzi and plumbing for the sink. Also I asked him to fix other plumbing issues around my house and I'm very satisfied with all this plumbing knowledge and workmanship. I would highly recommend Aqua Joe plumbing services"

"KSP Plumbing went above and beyond. I cannot recommend Kyle more highly. The developer installed our roman tub in a manner that now years later when the faucet and handles needed replacement there was no easy access. KSP had to literally cut through the tile to have access for replacing the faucet. The work was so expertly handled you can't even notice where they cut and then replaced the tile. This saved having to get a mason or carpenter. KSP's work was above and beyond excellent and at a fair price point. Five star."

"New kitchen was done over by Artisin Contractors that I would not recommend to anyone. New kitchen sink was installed by them and was not done correctly. After months of leaks and water telling them they need to get a real plumber at my house and not a carpenter to fix a plumbing problem he finally called Grade A and got me a real professional plumber. His name is Roy and very professional and knew exactly what the problem was. Roy fixed the problem. He respects your home, when he interned my home he covered his shoes. Very nice man. Thank you."

"We could not be happier with the Puronics Hydronex iGen Whole home treatment system and Micromax 7000 drinking water system provided by Orbit Water Solutions. Justin, the marketing rep who sold us the system, was very professional and accommodating. Justin took about an hour to demonstrate a series of tests which reflected to quality of our water which had more chlorine and hardness than we expected. If you have concerns for lead, Orbit standard demonstration does test for it so you will need to have a separate test done. After some negotiation, we were able to settle on a deal which got us the system and financing for the next 10 years. Orbit provides annual maintenance services on the machine and there is a lifetime warranty on parts which really assured us we were making an investment to improve our water. The best part about it is that the system travels with you. For a small fee, Orbit will pack the system up and ship it to your next home if you move which was a big selling point for us. Orbit also threw in a subscription to PureSelects soap for the next 10 years which was a nice add-on. PureSelects provides every kind of soap or cleaning product you could ask for so it will be nice not to have to purchase additional soap products in the near future. Within a couple days, the installation team came out to install the system. They arrived on time but the installation took a little bit longer than expected. Turns out our the installed garbage disposal was too large to fit with the RO unit tank under the sink. Orbit was very accommodating though. Orbit purchased a new garbage disposal and installed it free of charge which I bet many companies would not have done. I highly recommend getting the larger of the under sink tanks for the RO unit. Even with the two gallon tank, my family has used up all the water in the tank. A 1 gallon tank would just not have been enough. The water in our house has been incredible since we installed the system a few months ago. We noticed an immediate impact to our skin and hair after using it and our drinking water certainly tastes better. Best of all, we feel confident in the quality of the water we use throughout the house to keep us safe and our appliances in good condition. We highly recommend the investment in the water treatment systems through Orbit."

Ed, the owner of the company, was the plumber who completed this work at my house.  He was professional, experienced, and very respectful of my home.  He completed all of the work I needed.  He knew exactly what the toilet leak problem was and he was able to get the part to repair it.  I purchased the kitchen faucet that I wanted installed, and he did this work well.  He was also able to tighten the toilet in my main bathroom and even caulked it along the floor to add stability.  My previous contractor forgot to do this!  I was very grateful for Ed's knowledge and expertise.  I have used other plumbers in the past, but now I feel like I have found the one I want to use all the time when I need plumbing work.  I highly recommend Ed's company (EFD Plumbing).  Service costs were reasonable and Ed was considerate of costs as we discussed pricing for all of the work. Everything about this experience with EFD Plumbing was excellent.  I will recommend this company to my friends and family!

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