"I had an Absolutely Fantastic Experience!! My husband & I were so lucky to have gotten Jason Scharf to come out to our home, he was very insightful, helpful, courteous and very professional. Jason explained step-by-step what he was doing along the way & what would work best within our home with 4 different price ranges that would work for us. Jason was very informative. He mentioned and advised me on some items that would require attention on a monthly basis which I was grateful for. Upon completion, he reviewed the bill and explained any questions that I had. I was very pleased. Overall, Jason’s work was outstanding. I would recommend Jason from Astar to anyone I know that is in need of a central air system in their home. He was one of the kindest, funny and coolest Design Specialists by far. Thanks again Jason you're the Best! We can't wait for everything to be completed."

"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."

"Found J&J Plumbing and Heating to purchase and install a gas heaterand the owner Josh showed up did a wonderful job and was very helpful to male sure i knew how to use it before leaving and did a complete walk through with it. Josh was very polite and professional. Over christmas weekend i had a toilet plug in one of my apartments. After calling two local companies i began looking online and reached out to J and J forgetting they did plumbing and heating. After speaking with Josh he said he had a busy schedule but would squeeze me in. Josh was here quickly and was able to help me out for over half the price of other companies. I highly recommend J andJ for your needs. They are there to help quick and very professional. You couldnt ask for a nicer guy very friendly and down to earth guy. He will continue to jave my business. Thanks J&J"

"I required a new water heater installed and Diana builders were able to give me the exact water heater I wanted at the most competitive price. Dave took the time to explain what he thought the best solution was in plain English, gave me a quote a few hours later after researching his exact costs and stuck to his quote."

"High Tech recently re-brownstoned the co-op that I live in on 83rd Street and did an amazing job.  The price that we got from High Tech was about half of what we were quoted from the next lowest bidder, but the work ended up being so beautiful that people walking by our building are stopping to take photos.  High Tech reconstructed all of the old brownstone details that had been worn off and totally lost over the years.  These guys were artisans and asked me for very old photos of the building, which they used to re-create the designs of the building details.  It took a bit longer than I expected but It turned out so great!!!  I never expected that they could bring our building back to it's former glory, especially given the reasonable price.   Come walk by and take a look.
A couple of years ago High Tech had done our stairs, which also came out beautiful.  They got the detail right on that too.  The brownstone stairs look so nice, they have rounded edges like the most expensive brownstones have.  But again High Tech's price was the most reasonable of the bidders.  The have also done some other smaller jobs for us such as re-pointing and again I was very satisfied with both the quality of the work and with the price.
Oh, I almost forgot.  The electric company did some work on our block and chipped tiny bits off of the new stairs and High Tech came and repaired it at no cost.  I was very impressed with that since it totally above and beyond.

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