I hired the services of Upgrade Insulation to insulate my home and they seem to have done a great job. More importantly, they did the job timely and I am impressed. I will certainly be recommending them to friends, relatives.
We just finished renovating our home and needed new insulation throughout, and Upgrade Insulation took care of the crawl space, attic, and walls. They used batt insulation in most areas and closed-cell spray foam in the attic. Everything passed inspection, and the rooms are cooler and quieter. They worked fast, didn’t leave a mess, and respected our home. Such a reliable crew.
The crew from Upgrade Captain did an excellent job with my home insulation installation. They showed up on time as scheduled, thoroughly went over the details of the project, completed the job per our demands, and even cleaned up everything afterwards. Thank you, John!!

We chose Armour Hawthorne Insulation based on their strong local reputation, and they lived up to every bit of it. Their team was knowledgeable, honest, and focused on solving our specific comfort issues rather than just selling a service. The installation was flawless and the cleanup was impeccable. Our home is now cozy in the winter without the heater running constantly. The improvement in both comfort and energy efficiency has been dramatic. Highly recommended.
Our experience with Armour Hawthorne Insulation was excellent. From the initial consultation to the final walkthrough, everything was handled professionally. The crew was skilled, efficient, and respectful of our home. They transformed our under-insulated attic into a properly sealed thermal barrier. The results speak for themselves: a more comfortable living environment and lower monthly utility bills. A reliable and trustworthy company that does exceptional work.

In November 2024, we hired Top Energy to install ductless mini-splits in two studio spaces and the garage on our property. Leor was very responsive and knowledgeable, and helped us determine the location and size of the systems. Installation was one day; pricing was fair. The crew even returned to do several other handyman projects, which went well. Adding climate systems to these rooms has been a game-changer in how we use the space. Highly recommend Top Energy!
When both of our AC units unexpectedly stopped blowing cold air Top Energy Solutions was able to get a tech out quickly to diagnose the problem. It was discovered our system had a leak in the lines running under a patio. Leor came up with a solution for us and the next day removed the old systems and installed 2 new systems. The crew was efficient, professional, and did quality work. Because of that we had Leor and his crew come back the next day and insulate the attic and install an attic fan. I couldn't be happier with the communication, efficiency, and professionalism of Leor and his crews!
Top Energy Solutions is the best contractor I have hired. Leor is responsive and professional. I acquired three quotes to have my HVAC system replaced. I accepted Leor’s quote, and the installation started, and was finished by the end of the next day - amazing. A crane was required to remove and replace the AC unit on a three story house. His installation crew was very friendly and very good natured. He beat the other quotes by more than two thousand dollars for the same equipment. Leor is a general contractor and has crews for most home repairs. I will be hiring Top Energy Solution again soon.

Great service.
Got three quotes for attic insulation and radiant barrier installation. Thermal Wrap was competitively priced but their knowledge set them apart. The estimator spent time explaining the science behind radiant heat transfer and why reflective barriers work differently than mass insulation. Installation crew was efficient and left zero mess. Our home stays cooler all day and the AC actually cycles off now. Great experience from start to finish.
These experts are in a league of their own. We built a new home and wanted the highest performance possible, so we had Thermal Wrap Insulation seal and insulate all of our exterior walls and roof before the drywall went up. Their attention to detail was remarkable—creating a continuous thermal barrier with no gaps. Now that we live here, the difference is astounding. The house is silent, draft-free, and unbelievably efficient. This is next-level building science applied perfectly.

I've used RBH twice for insulation at my house and have had nothing but great experiences with them. Both times I worked with Mike who was very thorough explaining the various insulation options. The install crews also did a great job. For insulation RBH is the only company I'll use
this place has more insulation and more soundproofing products than anything else because they are specialized in this so they have great prices and a great staff ask for Susie she's amazing.
The experience was great. Working with the estimator was very easy and professional; his knowledge was invaluable in making decisions and planning the next phase. The front office as extremely professional and helpful; they were extremely effective in helping solve problems and scheduling installation. The installation crew was professional and quick. Overall, the company is one of the best I spoke with when interviewing for my project.
