"Count line replaced some plumbing pipes that where failing. The work done was professional and the experience was exceptional. I will be recommending county line plumbing to anyone in search of reliable a plumbing company. County line also has replaced my oil furnace system with propane furnace. The job done was very well planed out with shut off valves for servicing and organized routing of pipes. "

"Cody and his crew were amazing-- we had a complicated issue that required multiple visits and coordination with the city's engineers. Cody was professional, knowledgeable, and as dedicated to getting the job done right as if it had been his own home. His quotes were accurate and competitive, he and his crew were on time (and often stayed late!) and kept the work area clean and safe. We will never call anyone else!"

"Great, as always. Sila is outstanding. We have a service contract with them for our furnace and AC and they keep them in tip-top shape. And when we have an urgent or emergency situation (heating, cooling, plumbing, electrical), they're who we call."

"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

"Terrible. Just terrible. Whenever we had a conversation about what was included in our purchase or not, he was ALWAYS switching up his statement. Lou is full of empty promises and we had a poor experience with him. He recommended his brother, Chris Mellilo, to be our contractor. Upfront he seeemed like a good guy but it was our mistake. It took this guy over 6 months to complete 1/2 of our kitchen. BEWARE of Northeast kitchen and his rude and flakey brother who ruined our lives for over 6 months. Find another place to get your cabinets and do not listen to these guys. Terrible, just terrible."

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.
