“They were very thorough in their initial quote. They provided evidence of the kind of work that we needed. They explained everything very clearly. They installed some insulation, as well as a new fan in our bathroom. I'd rate it an A. Their quality of work was great. We have really good quality insulation that's clean. We don’t have all the fluff going all over the place that you have with you know, the traditional insulation and our basement has been much warmer.”

“They were in and out quickly and they did the job that they said they were going to do. It went fine. They insulated an exterior room in our house. It was a full insulation, not your typical insulation. An A is fine.”

“I had a positive experience.”

“They were on time, reasonably priced, and did what they said they were going to do. They removed old insulation and installed new. I'd give them an A.”

“They seem very knowledgeable. Comfenergy did some insulation in my basement. It's really a B+. They're very busy and it was very hard to schedule.”

Review by

“They came and did a good job, very nice and very good. They added more insulation to the attic. I have noticed a difference in my energy bills. It's an A.”

“Their work made it positive. Comfenergy did insulation. They did excellent with no issues across the board. I've already recommended them.”

“It solved my problem. They used foam insulation. The comfort of the home is probably better. I'd rate them an A.”

“Comfenergy provided the service that they bid for within the budget that we had agreed. They were careful and they were quite professional. They put insulation in the attic. I'd rate the experience with an A.”

Review by

“They did insulation in the attic. Their professionalism made it positive. I have noticed a difference in the comfort of my home and energy bills since it was completed. I'd rate it an A.”

Review by

“He was easy to get a hold of, and we did a lot of communication back and forth so I think communication was a plus. We had some heating discrepancy between the rooms, so they did some insulation and venting. I would give an A-. It was a tough problem. It wasn't something we were expecting a quick fix.”

Review by
10/05/2017

“Initially when they did the job, there was supposed to be a deck with some walls on the side. They didn't put the walls to keep the insulation from falling into the deck area. Once I contacted them, they sent another guy back and he added it. I guess I'd rate it a B.”

Review by
10/05/2017

“They explained the bid very well. They came in at a very competitive price, did the work on time, came back and fixed something that I asked them too. I think it was a positive experience. They installed insulation in our second floor. I think I'd give them a B+.”

Review by
10/05/2017

“Well, they kept at it. They had to come back a few times, and they weren't weird about pricing and all that. Comfenergy wanted to solve the problem. They did some sealing up of some insulation in my house. I was having some leaking. I would say it's a B+.”

Review by
10/05/2017

“I think the way they did the work and their customer service when they're here was positive. They cleaned up well after themselves, and they just got the job done when they said they would. They put in insulation in the attic area. I'd give them an A.”

Review by
10/05/2017

“It was very good. They did everything they said they were going to do. They were informative, and they handled themselves professionally, great deal of help. They used foam insulation. It was A+. They did everything they said they were going to do.”

Review by
10/05/2017

“Just the salesman and then the workers made it positive. They always kept me up to date on what was happening and got the job done pretty quickly. The most thing that I really noticed was the lack of water under my house. That was what I was really concerned about. The insulation, I really didn't notice because that is in my kitchen. I have tile floors and it just absorbs the cold anyway. My big thing was dehumidifying underneath and the two sump pumps they put in. I give them an A. The insulation experience, I do know that it has taken a lot of the dampness out of the house, inside the house and all. I have no complaints at all. A across the board.”

Review by
10/05/2017

“I did have my roofing and siding done. I'm not sure if it was the contractor that did the insulation, but if it was part of that then that whole experience was positive. Of course, my roofing got taken care of. It got damaged in the storm and my siding got damaged also. So all in all, I'm happy with the work that was done to the house. If it's the insulation, I would say A. I didn't have any issues with the insulation.”

Review by
10/05/2017

“They did their work quickly and did a very good job and all of the interactions with everybody was very good. They did some insulation repair because there were certain parts of the house that weren't insulated. I would give them an A. They didn't step into the house. They did everything outside and they cleaned up after themselves. It was almost like they were barely there. They were very knowledgeable.”

Review by

“They're a wonderful company. I come across a company like them very seldom in my life. Everything that they did was honest. They did what they said they were going to do, when they said they were going to do it, and they did it well. They're A+. I can't say enough good stuff about that company. I also met the owner. He's why that company is the way it is. I certainly would recommend them.”

Review by
09/14/2016

“They'd get an A. I would be highly likely to recommend their services. As a matter of fact, I might call today to try and arrange some more work that needs to get done at the house, but I've been so busy lately I thought I'd try to get it in before this price increase goes up. It's not that I knew anything about them, but I knew about other companies, and I heard bad things about other companies, so I decided to go with this company. So far so good.”

Review by
09/14/2016

“The work was done in a timely fashion. The people I corresponded with were professional. They knew what we needed and were able to get the job done well. They were also willing to come back when we'd had some spots that they missed, some insulation spots. They came back and touched it up in a timely fashion. It was a good experience. I'll give them an A+.”

Review by
09/14/2016

“The people that were working there were fine, but what was promised did not happen. It was a big issue. The quality of work was mediocre. When they came out, they were fine. Their cleanliness was great. We have not seen a big change in our bedroom. They said there would be a big change and we have not seen that. I wouldn't recommend them unless they come back and solve the problem.”

Review by
09/14/2016

“I can't think of any problems we had with Comfenergy. They did the insulation work for us in February, and they were excellent. I'd give them an A+. They did the work for us just before we put the house on the market. We were very pleased with their advice, counsel, and the quality of their work. The guy who set up the whole project and the people who did it were all excellent.”

Review by
09/14/2016

“They  were punctual. They got the work done efficiently. Everything was cleaned up beautifully. They did everything they were contracted to do. I'd give them an A. The differences in my energy bill have been marginal if anything, but their punctuality was fabulous. They had expertise, and it seems to be working.”

Review by
09/14/2016

“They put in some insulation above my garage. I'd give them a B+. The quality of the product is effective. It solved the insulation problem that we had. In fairness to the crew, the work was done on Christmas Eve, on the 22nd or the 23rd of December, so there was a hubbub of stuff in a cold time of the year. Some of the clean-up was not done to immaculate standards, but, overall, I was very satisfied with the work that was done, and what we needed to achieve with it. I have no complaints with the quality of the work. Punctuality was fine. We had some clean-up work we needed to do on our own. Clearly they were experts in what they were doing.”

Review by
09/14/2016

“I think the quality of their work will result in more work in our complex. There are 155 units over here, all of them ten years old, and other people already have had more problems and challenges. I've recommended Comfenergy to other people in the area. I'm the chairman of the HOA, so I think we'll be seeing more of them. I would give them an A+, but there were a couple lessons learned—no big deal. They're committed to excellence, so it's a very good firm. I think they realize they've got other opportunities in this complex so they're treating the challenge with pretty good respect.”

Review by

“I still have a roof leak and now I have further damage to my home that would require mold remediation. I will have to pretty much gut the bathroom where I have the leak. They did the work, you know, you paid for the work, the work was ineffective. You called them because you have a warranty. The owner is rude. They string you along. So there are some red flags and the way that, what I experienced and the way that he handles my calls or my request for warranty work and having gone through a review at BBB and the way that he responded quite erroneously, very obviously - things like saying he'd been to my home, he'd never been to my home. There are a lot of red flags about this person and roofing, I deal with a lot of contractors. This was my home but not my only property, a lot of contractors and this guy really. Nobody should have to go through this. That money was hard for me to come by and I could have just torn it up or lit it with a match. And when it rains here, and we had some horrible flooding in Houston in June. I'm up every two hours, nighttime or doesn't matter, just like a newborn baby because it’s between the walls and it seeps into the baseboards so it's not like I can put a bucket under there and go to sleep. I have to put towels on the floor and then put them in buckets and throw them in the washer. I mean it's involved and it has damaged my house and no resolution with this guy.”

Review by

“They ran the insulation all in my clothes closet and it was a real nightmare. They didn't check to see if anything was sealed in the ceiling, which I told them about, and I had to make them stop the job because they just totally made a mess in my clothes closet and they had to take my clothes out and blow them off at the warehouse so I wouldn't recommend them to anybody. I would not recommend them to anyone. The owner was very rude and I thought they should knock the biggest portion off after what I had paid and they weren't willing to do that. They came and demanded I give them the payment right then when they brought my clothes back so I wouldn't recommend them to do any type of service. The customer service was poor because they started the insulation and they didn't check anything and they just had my clothes closet which I had linens, bedsheets, towels, and all my clothes and shoes in the closet. They just totally destroyed them and they had to take them out and blow them off. The cleanliness and expertise were poor as well. It was just poor service. The owner or manager was very rude. They came one day and then the next morning when they got here I told them I didn't want them to finish the work because it didn't live up to my expectations after they'd totally ruined my closet. I had to throw away shoes and everything.”

“I'd give them a solid A. You have to walk on water to get an A+ from me. They worried about everything. They were on time. They did exactly what they said they were going to do. They did a beautiful job; it looked great. We're very happy.”

Review by

“I don’t live in either house I've had done with Comfenergy, but I have clients who do and they seem to be very responsive. They come and do their work neatly, and, as far as I can tell, very completely. I have no complaints overall.”

Review by
09/14/2016

“I'd give them a B-. The quality of work was OK. It wasn't the greatest. The customer service was pretty good, and the punctuality was good too. I had to have them come back and clean up. I had to call them back and they had to bring people with vacuum cleaners.”

Review by

“They're excellent. They insulated a crawlspace and an attic, and the servicemen who showed up were courteous and very professional. The gentleman that I met with, who had the sales information, was absolutely perfect. It was a great experience all the way around. I would grade them an A+.”

Review by
08/11/2015

“They were very, very good. They were very careful about making sure that they put material down on the floor in the house when they were working, and they checked in with us many times when they were doing their process. They were very professional. They came and reviewed the job—it was a very large, complicated job that we needed five contractors for. We had a leak develop under our roof; we just had a new roof a year ago, and we discovered a huge leak in one of our walls. When they opened it up, they discovered that all three floors had mold and that the studs had been rotten down to a pencil’s size. So, we had five contractors who came and met with our main contractor, who found them because they were willing to do a smaller job for the insulation. A lot of other big companies weren't going to be bothered with it. They called because we couldn't give them the exact time that they needed, so they stayed in close contact so that it wouldn't take us longer. It was a nightmare, but they were great contractors—I would grade them an A+.”

Review by
08/11/2015

“They insulated kitchen pipes for me. We decided on what we needed based on what was happening in my kitchen—the walls had exposure to the outside, so we were able to assess what we needed. They were able to determine it, and they pumped insulation into my drywall. I just had a good experience with their technician. I got more quotes, but I thought they were more professional. I would give them an A. They were very professional, and the crew was accommodating.”

Review by
08/11/2015

“They turned my crawlspace into condition space, they did an audit and everything. It's too early to tell we are waiting for winter to tell. Overall it looks good it's neat we did not interfere they just did their work. I would grade them an A-, there is just a small thing that they should have taken care of but they left it. Overall it's fine.”

Review by
08/11/2015

“I remember using them. We had them do some spray insulation in our garage area. We had some issues with freezing pipes above the garage—we had two burst in three years. They came in and confirmed some of our thoughts and concerns about the lack of insulation and the areas where we had issues. They came up with a game plan for how to execute it and correct it, and in a couple of months, they were completed. I would grade them an A+.”

Review by
08/11/2015

“They were insulating a bonus room and fireplace. It was kind of half of an audit they didn't run the system but they looked at a variety of places. The estimator knew his stuff and he knew the places to look at first, that was pretty positive. The work was OK it was pretty messy, they screwed something up and came back and fixed it. I had to call them back to fix it. I think they just knew their stuff. I would grade them a B.”

Review by
08/11/2015

“They insulated crawlspace and sealing attic space. They did an audit, there was a little bit of a disconnect between the audit and the actual insulation. So there was an issue with some of the areas that the person that did the audit didn't see that the installer saw and they wanted me to pay more. But they deducted 20% off the price and did what they could. I would grade them a B+.”

Review by
08/11/2015

“They upgraded the insulation through the entire house, above the family room and the main attic and crawlspace under the family room. They did an audit, no it's because I investigated about three companies, they're the ones that made the most sense. Yes I talked to three people and they were very comprehensive and they were very reasonable in their pricing and so I went with them. I would grade them an A+.”

Review by
08/07/2015

“They were very professional—everyone that was here was professional, and they did a great job. I appreciated everything. They insulated a crawl space that had been giving me problems; it made a huge difference this summer, and I'm hoping it will make a big difference this winter. I would grade them an A.”

Review by
08/07/2015

“Yes that was a long time ago, I never saw or heard them, they came in did the job they were great. The only problem that I would have is that they didn't come back and do the bay windows that they said they would. I have four bay windows three of them were accessible they were supposed to come back and so the underside of the bay windows. They were a recommendation from subcontractor we hired. other than that I was impressed, they were concerned with spray foam and on all four walls of an internal room but what they didn't realize was that as an architect I tend to be a little over the top and wanted acoutic and not just thermal once I explained that to them they were fine. I would say the second one, they just never came back and followed up with the bay windows. I realize that it was a small amount and area.”

Review by
08/07/2015

“They did work many, many months ago for me. They insulated my attic, I found them on through the internet. Well I thought their customer service was very good. They were generally on time but one guy quit on them so they got delayed. They did a good job but I asked them for quotes on other work but they never got back to me on that. I thought that was a little odd. I would grade them an A-. I think on the work they did I would grade them a solid A, there was one part that they didn't design to their own satisfaction and the owner of the company came spent a day there correcting the work himself which I was very impressed by so they did a great job on that and the salesman followed through on the other work.”

Review by
08/07/2015

“They're great, they are very prompt, they are very organized and if there is a mistake or something got broke, they fixed it immediately. They've done several things for me they did a foam injection in the walls and they did insulation rework in the attic. I would grade them B+ can I do excellent with slight issue. When they were working on the attic they had someone step through the ceiling that they had to repair and when they injected the wall it bowed so they had to repair. I would give them a B+.”

“They were very responsive. They just put insulation in my attic after we had a pipe freeze—that's supposed to cure that problem. They were just very responsive; if you had a question, they would respond to it and answer right away. They’re grade-A.”

“It was very good. They were one of the only companies that I could find to do the actual work. It was great. We had insulation put under a bay window. He showed us how he did it, and when he came, that's exactly what he did. I would grade them an A.”

Review by

“I called them, and they did the work—it was very straightforward. They were suggested by a realtor. Overall, I’d say I had an A- experience.”
