Econo-therm is a top-tier family business. Our 90-year-old home had zero insulation in most of the house, leaving us freezing and relying on space heaters to supplement our radiators. Louis, his son , Vinny, and the crew completely transformed the house in just 1.5 days--insulating everything from the walls to the rim joists and crawl space. Louis came by to look at my house, used thermal imaging and brought pictures to show me what to expect. Very thorough, knowledgable, trustworthy and truly helpful. Honestly, I was a little anxious about them drilling into the mortar of our brick exterior, but decided to trust the process. Their work is seamless. I can't even see where the holes were! They left the house spotless, can't even tell they were here. We felt the comfort levels improve immediately. Highly recommend this team if you want honest, expert work from people who actually respect your home and know what they're doing! read more

Beyond impressed with this company. They delivered on every level. Louis Eisenberg has an amazing team. The head guy in the field has been with the company for 18 years or so. He more than knew what he was doing. He was extremely thorough, showed and explained to me what he was doing and why, and was OK with me checking in regularly to understand the process. I've already recommended to others and will continue to do so. Bravo. read more

Thank you so much for your amazing work today insulating the attics of our old 1960 house. The worker showed the beginning draft performed of 4444 vs 3500 when the job was completed. Together with the new thermostat that National Grid installed, we hope that our heating bills will be less in the future. The workers were extremely professionals, from covering rugs, furniture, etc. To addressing several issues found during the installation.  Thank you again! read more

Vinnie and his crew did a great job today insulating my old 1880 attic.floor. They worked fast and .cleaned up SO good after all the work .. Very Very pleased Thank you Vinnie and your workers. read more

I just realized that more than a year after I had my insulation done by Econo-therm, I hadn't posted a review. I had used them once before for my house in Queens many years ago. (Look for an earlier review from me that was very belated.) This blown-in cellulose job went very well also. They were neat, courteous and cleaned everything up. I highly recommend them and would use them again. read more

I am extremely grateful having used Econo-Therm Insulation. It has greatly lowered my gas heating bill considerably. Lou & staff were professional, clean, quick, & competent. I couldn't recommend them higher. A very happy customer for sure. read more

Never replied to my emails, texts or phone calls. They said the owner would call me back to schedule an attic insulation replacement but he never did. read more

These guys were great! Lou explained everything and was very helpful in assessing the heat loss in my finished attic space. He was even able to come evaluate the space the same day I called!. I was able to have the work done only a couple weeks after. The guys were Super professional, very neat, and added so much warmth to my finished attic! I highly recommend! read more

Great company. Workers are great very polite. Geoff was there to do all work as discussed. Great price . Couldn't be better. You won't be unhappy. read more

Louis and his crew were true professionals. They went above and beyond what was asked of them. Louis is an honest, hard-working professional which is a rare find these days. We would definitely recommend Econo-Therm to anybody looking to have an insulation project completed. Again, we couldn't be happier with their work. read more

To Louis and the crew, I can't thank you enough for the job you did over 2 days . Blowing the walls with 2 different products and leaving no mess is an accomplishment in itself. As winter comes I expect to reap the benefits of all your hard work. read more

Very professional. I called the owner to inquire about an insulation job with my brick home. The owner is very knowledgeable and advised me that based on the construction of my home, it is not suitable for insulation without ripping the walls apart and do from scratch. He proceeded to give me suggestions on how I can add some thermal value to my home and offer to speak to me again if I have any other questions. I wished my house was a candidate for insulation because I'm confident these guys will do a wonderful job. read more

Louis & his team are truly professionals @ their trade. Econ-therm did the 1st & 2nd floors of my home & now I am saving a lot more energy, the upstairs feels like we live in the Caribbean when the heat is on now for a house that was built in 1920 with absolutely no insulation. There was an issue where an are did not get done, this was no fault of their own, but Louis came back & checked the area himself & in a few days the crew came back & the area was done free of charge. If you have a home, new or existing, you can contact Econo-therm for all you insulation needs, you would not regret this. Thanks again to Louis & the entire crew for making this possible & for making my home much more comfortable. read more

Louis came to give me an estimate. Let me first start off by saying 1) he was on time. Lateness is a big pet peeve of mine. 2) it was a rainy day and when he came into my house he came prepared with booties so his wet boots did not destroy my house. 3) He was very knowledgeable as to what insulation would work best for the different areas of my house. The guys that came to do my job were on time, were all very courteous, worked neat and did a job that far exceeded my expectations. Much better than what I would have done myself. They even helped move around items in my attic since I could not due to my broken arm. I would highly recommend you spend a few extra dollars to have experts like Econo Therm do your project. read more

Econo-therm performed the free New York Home Performance with Energy Star Audit, applied blown in insulation to the attic, and closed all air leaks in the attic, garage wall (found problem) and crawl space. Then Ecotherm performed another audit to verify the results. The whole experience went very well. I actually chose Econo-therm based on the materials that they used and the professionalism of the audit staff. The Econo-therm Staff showed up on time, applied all the insulation and waited for the after insulation audit in case any leaks were found. Not only did the house show a 20% improvement, the how was 50% more air tight after their work. That means the actual savings in heating will be more then was proposed. The clean up after the job was well done and I do not have any complaints. Everything was either as advertised or better than advertised. read more

Econo Therm came out to Insulate my Flat Roof in Astoria. They are busy so getting an appointment as fast as I was able to before winter set in was fantastic news to begin with. The Crew were all very professional and very efficient. They were able to gain access to my roof, create the holes they needed and fill the crawl space with enough insulation to properly insulate my home. When the crew was finished they cleaned up and properly covered the Holes with Mushroom caps to properly ventilate the space. We felt the difference immediately and have saved since saved on energy costs. The cost was reasonable and worth every penny spent. If your looking for a home Insulation company check them out and give them a call. read more

I have recently used Econotherm to insulate my 70 year old house. Last year when the weather was cold, my bedroom's temperature could not get above 60 degrees. Since the insulation job was completed, the temperature has never gotten below what I had set the thermostat for. From the moment I met with Lou (the owner) when he came to my house for an estimate, I could tell how professional his company was. He explained very clearly what needed to be done to fix the issue. I received a detailed and very fair estimate that day. The company completed every single detail that they promised. Furthermore, the workers were very diligent and nice. I would highly recommend Lou and Econotherm to anybody in need of insulation work. read more
