CMB ENERGY is an insulation company with a 2-star rating on Google from 4 ratings. A 2025 customer said a confirmed appointment was a no-show and that phone calls went unanswered. A 2024 customer said the salesperson who quoted the job had left the company by the day of the work, and that the work was not done as quoted or explained: the ceiling was not reinforced, the old packed-down cellulose was not cleaned out of the attic, insulation got into a new bathroom vent, and spray foam got on a new washer and dryer in the basement. In 2024, that customer also said the gables were not filled and the bill's itemization had to be fixed three times. In a separate 2024 account, a customer wrote that the installers did not complete the scope of work, packed the furnace intake with insulation and left broken siding pieces and debris, including large staples in the driveway. That 2024 customer said owner Kevin had been supposed to reimburse $650 for the incomplete job for 9 months. In 2023, a customer said the men who came were hard workers who showed up when they said they would, and that a wall cracked in a small accident was fixed immediately.
Had an appointment scheduled, confirmed the day before. They never showed up, and wouldn't answer my phone calls when I finally got in touch with someone I was told they "would look into it" never got an answer..
This was over a year ago, but I received a postcard thanking us for our business, and would we do a review- here it is. Horrible experience! Lots of workers running around, seemed to know what they were doing. Key word -seemed. The sales person that came out and quoted our job, we found out- day of scheduled work- no longer worked for the company. Requested to reschedule more than once. They had no idea some of what we were quoted. Kevin had to come to our house to see what was up. My husband went and bought lumber, and had to go up in the attic to show them what was supposed to happen. They had no idea how to do what was quoted, but acted like they did. They should have said they didn't know how to do it. We would have stopped the entire process and done it ourselves, and just let them do the part in the basement. They didn't do what was explained, or quoted. My ceiling didn't get reinforced, we don't have a usable platform in the attic, on top of the cellulose. They were supposed to clean out the old cellulose that had gotten packed down, and clean out the junk that was left underneath by previous owners. Didn't happen. They got insulation in our brand new bathroom vent that they said they knew how to install. Now we have to take a lot of it out and do it again. Basement workers did ok, however they got spray foam insulation on my brand new washer and dryer, and left quite a mess. They were packing up, I asked how they insulated the gables? We have a dutch colonial. The sales guy had said they would cut holes from the inside and fill them, which I was willing to deal with. So we moved furniture, and my office all around, worked on my dining table while they were here, - but they didn't do it. They said they couldn't access from the attic, so they didn't do it. Since then, we have asked another company, and have been told they should have known how to fill those cavities. Also, did a horrible job on the attic hatch. Husband will redo it. It is not insulated. Still just a sieve. I had to argue with Kevin and his "billing" person regarding the bill. She tried to tell me that they gave me a discount, and I told her, as a fellow business owner, they did not do everything on the bill, and we were going to have to redo a lot. As it was, I had to get him to fix the itemization, 3 times. The final bill still did not show what was actually done. He said he would come back personally and fix the hatch... I told him I didn't want him in my home ever again. So, no. Red flag should have been when researching, they have a storage address in Maine, but their actual business seems to be in NH. How can they justify being a Maine energy efficiency business. Web site doesn't want to connect either. When the sales person left- Kevin should have contacted all of the customers that were quoted, told them he needed to review their scope of work, as the sales person, unfortunately had left, and he wanted to be confident they would be able to perform the work needed. Transparency. Horrible.
Bad experience. Installers were complete hacks. Didn't complete scope of work. Owner Kevin was supposed to reimburse me $650 for incomplete job for 9 months. Now completely dodging me. They didn't complete blower air test before work, so no idea if the insulation even did anything. I have broken siding pieces all over my house , they left tons of debris around the house including huge staples in my driveway. They also managed to pack my furnace intake with insulation. Call Kevin and CMB you want to get ripped off and your house hacked up. Maine efficiency should remove CMB from the program, ripping off the state for incentive $.
the men that came and did my house were very hard workers very reliable they showed up when they said they would, got the job done there was a little accident crack wall but they fixed it immediately . thank you guys for doing a great job i will be warmer this year Debra
