"I can't thank Steve enough for the work he did for us.  We had a few small parts of our Central AC system that had fried on us.  When we called Steve the temperature was 95 degrees and he understood the need to repair the system as soon as possible.  He came out within 24 hours, diagnosed the problem and returned with the proper part to fix it.  He was the 4th person we had look at our system and his quote was by far the cheapest.  My only regret is that I am just now writing this review instead of doing it after the work was done.  We found Steve to be professional, prompt and very nice to deal with.  We will certainly use him again if needed.

"The job was fairly straightforward and I had already procured the sink and most of the additional supplies but the job required some replumbing of both the water supply and drain. The master plumber worked efficiently and professionally and the job was completed in a few hours. The cost was determined from a standard table in a notebook but does not take into account the complexity of the job or whether materials are supplied by owner. Since I supplied most of the materials (plumber supplied valves and pipe and drain fittings) the price seemed rather high for around 3 hours work. However, I've had no professional plumbing work done recently and thus have nothing to compare it to. The plumber was very pleasant and professional and the work of high quality. I have no other complaints."

"I hired Derry Plumbing and Heating to come to my house to do some work in the bathroom. They were extremely professional, polite, and very reasonably priced. The owner, Dave, was very professional, knowledgeable, and was able to answer all my questions. The technician that came to my house was very respectful of my property and did an amazing job. I would highly recommend Derry Plumbing and Heating for any plumbing you need, and I will definitely use them in the future."

"The water heater replacement went really well but they haven’t called me when I wanted more services.  They went above and beyond to make it elevated in case my basement flooded again.  Two or three people came out."

"We hired Superior Kitchen and Bath to replace our existing bathroom and bathtub with a completely new bathroom with a walk in shower.  They were selected based on their very detailed cost estimate that demonstrated that they were experienced professionals and knew exactly how to approach this project.  The work involved demolishing the entire bathroom, expanding the bathroom area by taking an adjacent closet, relocating the air stacks, relocating the bathroom door to allow for expanding the shower area. After reframing for a new ADA compliant walk in shower, new plumbing and electrical connections were made and a new vanity, toilet and tiles, and plaster completed the project.  The end result was excellent.   Jane and Brandon and their team did a fantastic job.  They worked very closely with us throughout the project to make sure the vision we had for our new bathroom met our expectations.  I highly recommended this company for anyone considering remodeling their bathrooms

"We also took the opportunity to upgrade the kitchen lighting and back splash. Ivaldo and his son, Angelo (who did the work) did a great job pricing the job and even had an electrician they worked with do the lighting installation. Very nice and professional people and we would most certainly call on them again for other jobs we have planned at our house. It's comforting to know that there are still honest service people out there!

FAQs for plumbing installation for a remodel or addition projects in Amherst, NH

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.
