"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 "

"Thought I’d put this out there for any of you who are deciding that you need a plumber in the Atkinson area. I would definitely NOT RECOMMEND Matt from Happy Home P&H. In my opinion he performed an incomplete job, overcharged for it and made an unprofessional comment to me. You’ll have to decide if this is the kind of plumber you want for your job. On Friday 7/13/2023 I discovered a leak in my home. Water was coming through the kitchen ceiling. I did not know what was causing this. I called Happy Home P&H. I do have to say Matt responded quickly. Matt arrived and identified the issue as the toilet tank supply line between the toilet and the wall on the second floor. He mentioned that he recently had some other jobs in my condo complex as he acknowledged that our homes are on the older side. He turned off the water to the toilet, replaced the toilet tank supply line and completed the job in less than 20 minutes. I don’t know if he took a few extra minutes to check any other plumbing parts around the leak area to ensure all was in working order...but apparently he did not. I was charged $250 because it was deemed an emergency which I gladly paid. That evening I noticed that water was still dripping from the area of “The Fix”. I called Matt at Happy Home P&H and arranged for him to come back as I felt he did not completely fix the issue I had paid him $250 for. When Matt returned, before he even looked at the leak, he said he thought it was probably a nut that needed tightning at the water shutoff as the materials were old. He completed the "tightning of the stop packing nut at toilet" in under 5 minutes. I don’t know if he took a few extra minutes to check any other plumbing parts around the leak area to ensure all was in working order... but apparently he did not. He told me the charge would be $100 for coming back to fix the leak. I suggested the fix was something he touched the day before and should be considered as included in the original fix. He did not agree. I paid Matt $100. I told him I was disappointed about having to pay a second time and would be posting my disappointment on the Atkinson Community Facebook page and passing my experience onto my Atkinson neighbors. That evening I noticed that water was still dripping from the area of “The Fix”. I notified Matt of the continued leaking. Matt said he was busy today but offered to come back the next day. However he prefaced it by saying “even though I don’t want you as a customer” I will fix my work. I have decided to not allow Matt back into my home given his unprofessional comment and the fact that after two visits there is still water leaking from my toilet. I feel uncomfortable and do not want to allow a worker into my home who quote "does not want me as a customer". This was my experience with hiring Matt of Happy Home P&H."

FAQs for gas piping projects in Londonderry, NH

Plumbers with proper licensing and credentials install and relocate gas lines. When hiring a professional, verify they have experience with gas systems and all required certifications. Some homeowners choose to work with plumbers specializing in natural gas installations, as they have extensive experience with similar projects and understand the safety requirements.

The timeline for gas line relocation varies based on project complexity, permit processing, and inspection scheduling. The physical labor takes a few hours to one day, depending on the line length. However, the actual installation work represents only part of the overall project timeline. Your contractor should provide a specific timeframe based on your circumstances and local permitting requirements.

Your gas supply must be shut off during the relocation process. This safety measure prevents gas leaks while connections are being modified. Plan for this temporary service interruption by making alternative arrangements for cooking, heating, or other gas-dependent systems in your home. The shut-off generally only lasts for a portion of the work, often a few hours.

Relocating gas lines to connect new appliances is a common reason for this type of project. Whether you're installing a gas stove, fireplace, dryer, or outdoor grill, a professional can determine the best route for extending your existing gas system. The cost will depend on the distance between your current gas line and the new appliance location.

Gas line work is not suitable for DIY projects. Natural gas is highly flammable and potentially lethal if not handled correctly. Gas leaks can be difficult to detect without specialized equipment. Professional plumbers have the proper training, tools, and experience to safely relocate gas lines while ensuring compliance with local building codes and safety standards.
