"No invoice transparency at Sila Heating, Cooling, Plumbing, and Electrical. I had an appointment on February 16, 2026, to troubleshoot a no-heat issue on the second floor of my home. I was told the repair would be $1,500. Although hesitant, I agreed to proceed because I needed heat. The repair was completed, I paid $1,524.90, and the technician left. I later realized I had not been provided with an invoice, so I called the company directly at 781 438 4114. The person who answered the phone emailed me an invoice. The invoice listed an HVAC diagnostic fee of $69.00, followed by ?HYD 170,? with no price or itemized breakdown provided. I understand that professional services and parts can incur significant costs, it is unreasonable that the part alone could account for the entire charge without any supporting documentation. I respectfully requested a detailed breakdown of the invoice through multiple phone calls and emails; however, the responses I received were dismissive and failed "

Custom Painting Contractor providing Quality, Service, and Value since 1986

"It has been a week since Bob Gagnon (whose business is named Architectural Coatings) finished painting my bedroom and hallway, and I find that his masterful work delights me more each day. Because Bob is meticulous in his work, the ceiling, moldings, and doors with their precise edges and fresh new tone provide a clear contrast to the walls now smoothly coated in a delicate grey-violet. This new look replaces the tired wallpaper and worn woodwork of this room previously. Bob worked hard to give me this smooth look, having had to remove two coats of wallpaper in the hall and patching over gouges created in those walls in the past. Fortunately, the wallpaper in the bedroom was removed more easily but needed prepping and patching nonetheless. I liked how Bob prepared me for this job by leaving me with a variety of color samples on this first appraisal visit and giving me suggestions about what might work well for me as the light changed on the painted surface during the day. Because I am environmentally conscious, I was delighted when Bob told me he uses paint with zero Volatile Organic Compounds (VOC’s) and primer that easily gasses off and can be removed by a fan. When he was on the job, he also offered possible changes: would I like full louver doors instead of the half ones on my closet; would I like different pole arrangements to hang the clothes there; would I like the small top shelf to be replaced with a larger one? I saw the work in progress day by day and saw how painstakingly Bob went through each process. I also enjoyed having such a cheerful, kind, professional person as Bob in my house each day, and I enjoyed the snatches of conversation I would catch with him here and there. When the job was finished, Bob charged me his original estimate, which took into consideration any problem he might encounter, telling me that he would lower the estimate if possible negative things did not happen. He stated that the wallpaper in the bedroom was removed easily; however, the two layers in the hall with the gouging underneath balanced out what he had anticipated in the bedroom. I could sense that he was a man of integrity. Bob left my house in pristine condition: vacuuming, dusting, and moving the furniture, so that I could move back in without lifting a finger. Before he painted, he left the bed and two dressers in the middle of the room that were very securely covered with plastic so nothing touched them. He created his work area in the basement with all the appropriate tarps, which again was left pristine. No one would know a painter had been there except to see my beautiful new bedroom and hallway. Bob was recommended to me, and I thank the person who did so, and, in fact, just today, I recommended him to a friend-of-a-friend who was looking for a painter. I just can’t say enough good things about Bob Gagnon! It is a treat when we encounter someone to come into our home to make it more beautiful who is as truly excellent as Bob is."

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