"My buderus system wouldn't stay running when we started it up for the season. We gave fellowship plumbing and mechanical a call and Kyle was super busy but still found the time to help us out. Working with him and his team was seamless from the office to his helpers all went smooth and made a potential nightmare just a dream. Wouldn't hesitate to call them in the future for HVAC or plumbing"

"Upon contacting Ocean Point Plumbing I was greeted w a very friendly voice. I explained my problem, and need for some help and was offered immediate assistance. When Steven arrived he was very professional. He looked at my new shower and quickly went to work. I was very impressed and will definitely use his services again in the future!"

"They had to dig out and replace a section of the cast iron drain out through the fieldstone foundation of my house and added an exterior access clean-out. They came on time, were courteous, did a fine job, and cleaned up afterwards. They also charged me less than the estimate! I was very pleased... I couldn’t 't ask for better."

"We took out the old tiles, removed the toilet and baseboards, and bought the tile before they came to do the installation. The work was done on 9-01-16. When I went to wash off the remaining haze a couple of days later, I discovered that the tiles were two different shades. It was obvious when they were on the floor. The person doing the installation should have seen this. We think he did but, since he didn't speak any English, might not have known how to communicate that to us. We called Pacific Stone & Tile and they said that they would come and replace the tiles that needed to be replaced. We could not match either shade of tile and had to buy two more boxes with a different shade number. Twice an appointment was made and canceled. The third one, 9-26-16, was kept and they redid the whole floor with the new tile. Before they started, all of the tiles were laid out on the garage floor to check for any variations. We had to buy the material to install the tiles, but they did not charge for any additional labor. The floor was checked before they left and everything looks fine. Tomorrow I will wash down the tiles to remove any haze and we can start thinking about getting everything back together again."

"IT was great! I have never had a problem working with this company. The people (from the customer service reps to the billing to the drivers) have all been honest and realistic with expectations, answered all of my questions and never charged me more than what is advertised on their website. Patricia and Victoria have gone out of their way to return my many phone calls on the weekends too. You just don't get customer service these days anymore like the bullbag provides.They came when they said they would, did what they said they would do and did it professionally and pleasantlly. It is a pleasure working with such an honest and reputable company. Especially since the dumpster industry has not been know for this! These guys are definitely setting the bar high for all their competition."

"Platinum Carpentry was great to work with. The owner Dean is a very nice guy and easy to work with. The quality of his work is outstanding. We were out of town when the project was scheduled to start and Dean kept us updated on the progress and a few delays that were encountered due to weather, etc. We are very pleased with how the deck turned out and we would not hesitate to hire Dean and his crew again for future projects."

FAQs for plumbing installation for a remodel or addition projects in Block Island, RI

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.
