"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."

"Huge shout out to the crew at Main Stream Mechanical. Eric came out, reviewed my current system, and gave me his recommendation for replacing my furnace and hot water heater with a new, energy efficient furnace/hot water heater. Brenda, as always, was a pleasure to deal with. Answered all my emails and calls promptly and gave me all the information I needed in a timely manner. She even went out of her way to register my new furnace and provide me with all the information I needed to apply for my rebate! Nick and Marcus did a great job installing my new furnace/hot water heater. Both were very friendly and professional. Nick answered all my questions, gave me a “tutorial” on the emergency shut off procedure for my new furnace, and did a fantastic job re-plumbing all the lines needed for the install. I highly recommend Main Stream Mechanical for all your HVAC needs."

"have used Pettigrew Plumbing and Heating in the three homes I have owned in Portsmouth NH. Some jobs were constructing a new bathroom, remodeling an old one, installing a washer dryer set, moving a hot water heater, and installing a new HVAC system. The owner, John Pettigrew, and his skilled employees, are alway professional, know their trade, show up on schedule, work neat and clean, and are courteous and willing to answer questions. I would highly reccomend Pettigrew plumbing."

"I noticed a bit of water near my hot water heater.  <br /> After some research, I found that the relief valve required replacing.  I had used Happy Home Plumbing  previously so I called them. I called on Monday afternoon, and was told that someone will be contacting me.  A day went by and I hadn't heard back.  My problem wasn't urgent, but I did want it taken care of. <br /> Wednesday morning, Matt Boucher called and asked if he could check out the project. He arrived in the time frame promised and scoped out the work.  He agreed that the relief valve needed replacing, but recommended a water pressure valve install due to my high water pressure. Being in Haverhill and at the bottom of a hill, my pressure has always been extremely strong.  Matt had mentioned that it is now code. Although I could have passed on this, I agreed to have it installed. (I also had a water hammer problem and was hopeful that this would correct that problem.) <br /> Matt gave me a verbal estimate.  I agreed and asked him to proceed.  He then left to pick up the valves and some tools.  In about an hour and a half, he was all done.  He showed me the finished product and wrote up an invoice. <br /> I'm in good shape now. Thanks Matt and Happy Home Plumbing. <br />"

"Martel replaced our hot water heater four years ago (in less than 24 hours on Fourth of July weekend, no less) and I noticed today that it had started to leak. I called in to their office at 11:15 am spoke with a very kind and friendly woman who transferred me to Jeff. I left a message and had a call back in less than an hour. The heater was still under warranty, they had one in stock and the technician, Mike, was at the house in less than an hour and by 2pm the job was done! I have always had more than amazing experiences with Martel, but this one takes the cake. Jeff was very informative and helpful in diagnosing the issue and Mike was an absolute pleasure to have working in my basement. If you are looking for a stand-up company for any of your plumbing and heating needs, do not hesitate to call the friendly folks at Martel!"

"I spoke to Jay Sebastian on the telephone about corrosion on my water pipes. I told him I thought I might need my house re-plumbed. Jay said I probably had a high level of acid and I should consult with a water company. I did this and ended up getting an acid neutralizing system installed. The corrosion issue is gone! Thanks to Jay's advice I probably saved many 1,000's of dollars on a needless re-plumbing job. <br />"

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