"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"I ended up hiring company after I shopped around for my Boiler, burner and Indirect hot water tank replacement need. I extensively researched prices and companies in my area. Lou the owner returned my call on a weekend in case there was any emergency. After he only asked to send him photos and videos. And instantly gave me quote for two scenarios (Which btw he honored all the way). This was stark difference from other companies who had to set an appointment to come measure my house with expensive equipment or software (Which size and BTU output I needed I already knew). And tried to upsell me something I didn't really ask for. Sched beat others on price which was most important to me in addition to reviews. After I picked them company clearly communicated when Job will start and were very punctual. David and Guy (I didn't catch name) where very punctual - cleaned after, daily. Clark and Enfi (I hope I spelled the name right) joined them the next day. Also very punctual and professional - all worked with minimally disturbing my day, as I had to work from home. And Job taking one extra day, they did it, leaving everything clean. Explained me and gave advice on maintenance and tune up. I'm not a professional in this area but what they installed looks good after years of watching my rusty boiler and Tank started leaking ;-). Pretty much rebuild everything with new pipes and motor pumps. I hands down will recommend company without any hesitation. Definitely shop around. But have no doubts Schede will do the Job as well if not better than others with great quality to price ratio."

FAQs for plumbing installation for a remodel or addition projects in Old Greenwich, CT

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.
