"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"The professionalism and quality that the Insulation Labs team demonstrated from beginning to end should serve as a Master Class for any other service oriented company. Scheduling the estimate was effortless with clear, helpful and efficient communication from Diana, their first line of contact. Abraham arrived to do the estimate visit with kind patience and knowledge. He took the time to help us figure out how best to approach the insulation and was more than willing to answer all of our many questions. When we received the estimate we were appreciative of how easy it was to read and understand what the plan was. We knew exactly what to expect and how much it would cost. Today was the day of the insulation. Chris, Tzoc, and Moises spent a long full day doing the entire job. Throughout they were kind, professional, and did an outstanding, neat job. At all times, they cared for our space as if it were their's. We are so glad we chose Insulation Lab. There is no question we would recommend them to anybody."

"We had no problem or issue with this company. They came and did exactly what they said and promised. The service was fast too. We were able to schedule them for the same week and the work was completed after 2 days of work. According to the technician that worked at our house, it was better to use the opportunity when the attic empty from the old insulation and to replace the ducts as well. For the price that we were able to got, we decided to do that too.
so overall, we are in the stage that we will use this company in the future and we will refer them to people that we know and might need the same kind of work to be done.

"We just completed our remodeling project with Best Builders Group and it was a great experience overall. We added a master suite (appx 350 sq. ft.) to our house. We got several estimates from several construction companies and we decided to hire Best Builders Group for that because of their big experience in design, great price and great approach. The addition project was not simple at all but Zohar handled each stage of the work very productive and he always kept us up to date about the entire progress. His design was a huge advantage and it was the main thing that we couldn’t fins in the other ones. Our bathroom addition is definitely stunning and it’s our favorite part at the house now. Zohar also recommended to have a tile wall and floor tile that made the bathroom a beautiful one! More than that, he was very hard working worked extra hours because of our long schedules. Zohar and his professional crew were very respectful of our time and space. Overall, we are excited with the addition and thankful to Zohar and Best Builders group."

"At this point, i can recommend this company in case you need to have someone professional, reliable and not expensive to work at your attic in case you will have any issues there. This company came over and replaced the insulation due to several problems that i had there.
Their price was good too and they came to my house in the time frame that was set ahead of time by their office.

"This is part two of a review for NRG Heating and Air Conditioning. The first evaluation was written as a complaint for a job completed but one that did not follow the all of the stipulations of the contract. This review is written to thank the individuals from NRG who took the first evaluation to heart and then dispatched a team to fix the areas of concern. I am delighted to report that the work completed today was done per the contract. Not only was the barrier wall built between the two condo units as originally promised, the attic was insulated with the additional blown in material, the old attic door sealed and caulked, pictures taken, and the area left clean and tidy. I am most grateful to the general manager, the quality control manager, as well as the insulators who made sure the job was finished per the original contract. NRG should be recognized as a company that not only took the time to read a customer service review but then acted, in a timely manner, to resolve the issues addressed in the complaint. I am most grateful for NRG's time and willingness to take responsibility for and to complete a job as promised. Thank you!"
