I've used Diversified Energy twice for an energy audit and duct sealing, and once to fix insulation issues and air seal a subfloor. They've been fantastic every time. Jeff is incredibly knowledge, friendly, and thorough. I really felt like he took pride in ensuring the work was done to the highest standards. I wouldn't hesitate to hire him again for any additional work!

These folks don't just lay and spray. The folks at Diversified, especially Jeff, are building science experts. Professional, knowledgeable, and fair. Look no further, especially if you have an older home or a tricky insulation situation. Diversified won't steer you wrong.

Steve B.
Absolutely the best in New Orleans metro for wind mitigation work. The foam spray was done professionally and customer service was top notch. I would recommend Diversified Energy to anyone trying to lower their homeowners insurance and solidify their roof.

Thankful for Jeff and Diversified Energy! I called Diversified Energy on a Friday afternoon to start to learn about options for insulating our floor. Jeff spoke to me for 45 minutes ensuring all my questions were answered and I knew what I was getting into. Thanks Jeff!

Jeff is exactly the kind of contractor you hope to get when you’re researching any job. He’s personable, transparent, and thorough and his company is a testament to the same principles. My experience was unique in that I had talked to a couple of companies already but Diversified Energy was the first to tip me off to the Energy Smart program which would foot a large portion of my bill. Jeff took the time to explain the process and the best way to go about it for me - eliminating any uncertainties I might have had. He explained the intricacies of the work and sent me links to articles/white-papers on the pros and cons of certain methods. Never at any moment did I feel I was in the dark and I felt fully in control of the improvements that were to be made to my house. Throughout the process Jeff was always just a text-message/call away. Before the install he touched base with me to ensure we were all on the same page. He was present the day of the install to help his crew and came back a few days later by himself to round out the job. His crew exemplified the same characteristics as Jeff and I was very impressed with their work and dedication. I wouldn’t hesitate to recommend Diversified Energy for any service they offer and I look forward to working with them again as necessary.

J’Rell and Xavier were excellent!

Caleb B.
Jeff and his people did any amazing job! Couldn’t have asked better, after me and my wife dealt with a shady contractor who we found out was a convicted felon for fraud and also frauded us out of thousands of dollars, we were hesitant to get our attic fixed cause we felt it was an actual crime scene. It also put a very sour taste in our mouth dealing with contractors ever again. Jeff changed that for us. He made me feel like he actually cared and gave a very in depth view and his expertise on the work from the previous POS contractor. Highly recommend them, they stay true to their word and keep you up to date with any changes and did an amazing job!

Jason M.

Tron and J'rell were able to accommodate me with my appointment by arriving early. They worked hard and were knowledgeable of what they were doing. They did a great job!

Brandy P.
Niki and Ricky were very knowledgeable and helpful as they made my house more energy efficient. They both thanked me for welcoming them into my home when they were the ones doing a service for me. The things they pointed out to me were very important and informative. They fixed the issues they found and this service was completely free. I am most grateful that they took the time to test so thoroughly for any interferences with my duct work that were affecting my air condition units. I highly recommend you contact Niki and Ricky with Diversified Energy for your home.
