I had Ram Insulation help with my attached garage project. They showed up on time with three-man crew and completed my 20' by 20' garage insulation within a day. They have done very nice and detail-oriented work and my garage looks brand new and ready for the next step.
Miguel and his team were referred to us by our HVAC vendor. We had them remove and replace the insulation in our home. Miguel, Adolfo and the crew were punctual and professional throughout the project. The entire project took 3 days and they did a great job of prepping our home, covering areas to protect and keep clean, removing the old insulation, and cleaning out any remaining debris before installing the new material. Adolfo took the time to explain what would happen during each part of the process including what things I can expect from having the work done. They were also good about the cleanup work when they finished. I already notice the difference in how much the new insulation is helping block out the heat inside my home. Hard working and dedicated crew. Would highly recommend using RAM for your home insulation needs.
Miguel’s team, Hector and Alfonso did an outstanding job of insulating our attic. They came bright and early and blew in insulation as well as laid rolls of insulation throughout our space. They were professional and courteous. They even had to deal with sharing space with a painting crew that was at our house to finish up a project. Super good folks and the insulation project was priced very competitively. Give Miguel a chance to bid for your business. You won’t regret it.

Attic Shield was awesome! Elliott Hadida was super helpful and easy to work with and the team did a really clean and professional job on my whole attic. What really impressed me was that after they finished they sent me over 160 photos showing everything they did. It gave me a lot of confidence that the job was done right. The attic looks great totally recommend Attic Shield!!!
They were very fast to respond with an inspection to service. Great price and customer services from Elliott and Christine. Great crew with Justin as a leader who came on time and worked hard all day. John came quickly to inspect and follow up after the service. Everything went very smoothly and I feel so good to know that my attic is clean! Thank you for explaining about tax credit and answer ing all the questions I had, Elliot.
Everything about Elliott and his team is fantastic! Where do I start? His most impressive quality is his honesty. Always putting the customer first! I used to run a business and my experience with Attic Shield is who I want to do business with! Personable, great price, exceptional work, great communication! 10 out 0f 10! Phenomenal job! 👏👏
