I wanted to install additional insulation to lower my heating bills. The team came out, and although they couldn't add additional insulation because of the type of insulation I already had, they were professional, knowledgeable, and answered all my questions. They didn't charge me for coming out and surveying my home. read more

Met with RISE Energy / Mass Save for Home Assessment, needed to have a wall in my house checked out as were experiencing pipes that were freezing. Per the inspection, our assessor determined that wall with the pipes did not have any insulation and there were other walls in the house that were also lacking sufficient insulation. At the recommendation of Mass Save, they put me in touch with 5C Energy to perform the work which hasn't gone well to say the least. First, they missed the appointment day. They called me later apologizing for not coming and would come back the next day. Next, the individuals came out and started to perform the work. They first confirmed the bay for which the pipes were were freezing was uninsulated and began the work to plug the hole in the basement with foam insulation so that the insulation up top would not spill down to the basement. Soon after, 5C as they were pulling the siding off, they said the house was insulated but didn't have the scanning tool to check more accurately. They had to request one be brought out to them (not sure why they wouldn't already have this tool?). Once that came, they scanned the house and did confirm there was insulation in many of the walls (not counting the bay with the water pipes) but was really spotty. Showing numerous spots without sufficient insulation. Soon after the workers came to me (after speaking with their boss Matt Russell) - he told them that the job wasn't worth performing even though I had a wall that was confirmed to not have insulation with water pipes. Exact words he said to the guys was "I'm not going to have my guys out there to insulate 16 square feet". Wow. I asked to speak to him for which he immediately hung up on me. He pulled the guys and wouldn't allow them to finish the job and left me high and dry. Still have a wall that is uninsulated with water pipes. I did escalate to the company representative I had dealt with and she did contact Matt and gave a different false story as to why they wouldn't perform the work. Also, wouldn't admit to straight up hanging up on me. Be a man and talk to me if you want to cancel the job. Terrible company. Terrible Service. If your job turns out needs less work than their bottom line, they will feel free to CANCEL the job on you. Hang up on you and send you on your way. How they heck did they get connected with Mass Save and RISE Energy is beyond me. Stay far away from this company! read more

My prior review may not have posted, computer issue, and want to make sure my terrific experience with 5C gets recorded. I went out for 4 bids. 5C was the lowest which concerned me, but the ended up exceeding my expectations. Cleaned everything up, the building inspector passed them immediately (and he is tough), professional crew, on time. They may be the only enjoyable experience we have had on our addition. 5 stars + Charles Kelley read more

The 5C crew spent 8 hours insulating my house, (no lunch). Toby, Ryan, Eric & Rob worked on the house. All are exceptional workers, very professional, patient & kind. They all took the time to explain any question I had and to explain what & why they were doing what they were doing!! Whoever does the hiring at this company should be applauded as these are the best "workers" I have seen in a long time. I couldn't be happier with the time, effort and thoroughness of their work. (They even 'discovered' 2 of my bathroom vents that the original builders had not vented correctly and remedied that situation read more
