"We had a very good experience with Morris. They provided a detailed quote, explained the options and the process very well. Their installers were friendly and happy to answer questions. They did a clean and tidy job of the installation. The subs that they recommended for electrical work were also excellent. I would recommend them to anyone."

"We could not be happier with Brandon's work, punctuality, cleanliness, personality, communication, honesty, pricing, and overall character. We actually had contracted to do some extra work for a few thousand. Day 1 of the job, Brandon calls to let us know that we do not need to do the work as he took the time and effort to get other opinions on the installation of a beam. Again, character. He could have easily installed, but he took the time to do right by his customer and that, in our experience, is essentially unheard of. The work he completed for us-on schedule-was more than we could have hoped for. He really does great work, listens to the customer (we are guilty of making many changes and talking far too much), but Brandon is beyond patient and willing to work with you. If you are looking to remodel a kitchen, bath, or in general, look no further than Superior. You are hiring someone who truly cares about his work and the customer. Rare in any business these days. We will definitely hire Brandon when the time comes for our next project-no hesitation."

"I used MA Design & Construction for my kitchen remodel. Raquel and Marc were very helpful in going through the options from painting the existing cabinets through to full replacement. We started with more modest changes but after debate ended with essentially their initial recommendation. The workers throughout the project were professional and I never felt uneasy with them being around the family. As the project progressed there were recommendations that Marc or Raquel would make which led to a better outcome. Marc would also pick out imperfections in the work and insure they were addressed which was appreciated. We're very pleased with the outcome and would not hesitate to work with them again."

"The contractor added a second floor to an existing home. The addition consisted of: adding  a  TV /Family room, a master bedroom with a walk-in closet and a master bathroom. Remodeled our kitchen, replacing our old tile floor with hardwood floor, added new deck and a sun-room. Overall, My wife and I are very happy with the quality of the work, and manner in which Mr. Ivaldo; the Owner; conducted his crew and performed the tasks at hand. I would highly recommend him and definitely would use him again.

"Bay State did an AMAZING job with our house. We originally hired them to redo 2 bathrooms - then, after a different company backed out of our HVAC installation right before the winter, Bay State came to the rescue and did a wonderful job with the remodeling required for that, too. We decided to expand the scope of our home remodel (to include a kitchen remodel, opening up the floorplan, etc.) because we were so impressed with the quality of their work, and we are very happy with the results. It was a pleasure working with Marcio, Andreina, David, Marcus, Mr. Fixit, Dayna, and everyone else involved in the project. We are so glad we went with Bay State - they are professional, detail-oriented, trustworthy, and committed to quality. Also, they know how to make things look really good!"

"We hired Todd for an extensive remodel of our home and couldn’t be more thrilled with how nice it turned out, how smooth the process was, and how helpful Todd was along the entire way. The project has been complete for a while, I am just now following up with a long overdue review. Downstairs Todd removed 2 walls including a staircase to create an open living space for us. Where the walls were removed, he installed 3 new support beams per the engineer’s design, and then wrapped them with rustic oak boards to make them look like original beams, and they turned out beautifully. He installed all new trim around the downstairs windows to match the rest of the house. Todd gutted our old kitchen and built an island for us, installing all new cabinets, crown molding, and the appliances. He even custom modified 2 drawers in the island so that we could conceal the electrical outlets behind part of the drawer panel but not lose the entire storage space of the drawer. He did such a great job with the drawer modification they look like they came that way from the factory. The entire kitchen turned out perfect. During the same remodel, we also hired Todd to combine 2 bedrooms into a new master suite. This involved removing walls, installing a beam, and installing new walls for the new master bathroom and closet. While the ceiling was opened up Todd noticed a drip coming from above on a rainy day, and after finding the source, he offered us a very reasonable price to replace a small section of siding to ensure we wouldn’t have any water issues. We are grateful he was so observant and willing to go the extra mile for us by fixing this issue that was not originally in our scope. In the new master bathroom the extensive amount of tile and the new glass shower enclosure that he installed couldn’t have turned out any nicer, all the lines were perfect. He took great care in his tile usage, minimizing waste with his cuts which we appreciated especially on the expensive tile he installed in a decorative strip. Todd was great to work with throughout the entire project and very professional day in and day out. Being such a large project, as it progressed there were several things we realized we wanted to add to the workscope while everything was opened up. Todd was very accommodating and gave us reasonable prices for each addition we threw his way. We appreciated his flexibility very much. Todd also helped us with various design considerations, and had some great ideas that helped us work with the engineer to get the upstairs beams laid out in a way that optimized our new space. He pays close attention to detail and worked hard to ensure we would be happy with the end result of the project. Overall Todd is a real pleasure to work with and we highly recommend him and the quality of his work."

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

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.
