Eco Energy Solutions added blown in insulation to my attic floor. They also went above and beyond and added insulation to the walls of my upstairs rooms and a thermal shield. Extremely thorough and professional. They were in and out in a day and I can tell a huge difference inside the house ever since. The work was also very reasonably priced. I am very satisfied and would use them again.
The two man crew arrived and set up quickly. They went through the steps for the application like a "well oiled machine"! My 16 x 20ft shed is sealed tight. I appreciate what Eco Spray Foam did for me. I recommend them to all who need insulating done the right way.
Eco is a wonderful company to work with. They did everything they promised they would do plus did an outstanding job cleaning up when they were finished. I was completely satisfied and would highly recommend them again and again.

Sunlight Contractors did an outstanding job spray foaming under my house. Their entire team was extremely professional, kept the workspace clean, and left everything neat when the job was done. They communicated clearly throughout the process, keeping me informed of the progress and next steps. The quality of the work and the service exceeded my expectations. Highly recommend Sunlight Contractors!
Sunlight Contractors best Spray Foam company in the South. This is my Second New Construction Home I have built in Mississippi and this is the second New Construction home I have had Sunlight Contractors install Spray Foam. The first home was about 4 yeas ago and I found Sunlight Contractors searching for hours on the internet and reading review’s on many contractors. After talking to Ira several times, I was convinced I had found the company I had been searching for. When it came to the second home I contacted Ira again to get an estimate which he was happy to give me. I contacted several other Spray Foam installers and got my normal 4 Quotes for a Job. Some were less expensive than Sunlight Contractors but after talking to the other companies and there process I soon knew Sunlight Contractors was the only choice out there. I had some problems with the City Code inspector and was delayed 4 months after signing the contract before I was ready for the Installation. Ira stayed in contact with me the entire time and told me to let him know when I was ready for the installation. I contacted Ira on Friday that I was ready for install and he had the crew at my door the following Monday morning. Sunlight Contractors crew did a fantastic Job and I would highly recommend them for your Spray Foam Installation needs. I haven’t used any of there other services but if they say they can do it I have all the confidence in the world that they can get the job done.
After our home was destroyed in 2021 to Hurricane Ida and having to completely rebuild, I dealt with many sub-contractors during that process. Fast forward to 2023, we experienced one of the hottest summers ever in south Louisiana. My two brand new AC units simply couldn’t compete with the heat and lack of airflow in my attic. I decided to have our attic spray foamed but, with the industry being unlicensed in the state of Louisiana, I came across countless companies that simply didn’t have the credentials to back them up. Until a friend suggested a larger company, Sunlight Contractors. Well, they may be a big company but they sure don’t make you feel like it. The owner, Mr. Ira, called me back personally and gave me a very detailed run-down of the process and how it would all work. His communication was thorough, clear, and accurate. They did exactly what they said they were going to do and did so exactly when they said they were going to do it. Even in 100+ degree heat, they came in and removed all of my old insulation, bagged it up and hauled it away, sprayed my attic and added a level of comfort for my family that we had yet to experience since living in our home for the last 9 years. His crews were professional, clean, and I barely knew they were even there. My electric bill, previously $600 a month, was cut in half and I’ll pay for my foam investment in a couple of years. Of all the contractors we used during our rebuild, there wasn’t one in the same sphere as Mr. Ida and his team. If you’re considering foam and are unsure, give them a call. I can guarantee that you won’t regret that decision.

Fontenot Insulation insulated my home. What a big difference it made! My home is much quieter & the AC runs half the time it use to which saves a lot on my energy bill. I’m so glad they did my home! They are a family owned company and are so very professional & friendly who really cares about there services they provide to all its customers. I would “Highly” recommend Fontenote Insulation & their services……
Excellent customer service and top notch work. They make sure it's done right the first time. They also take time to explain what is going to be done. Highly recommend!
I was so happy with this awesome team from Fontenot Insulation! They removed all my old attic insulation and blew in a R-30 rating. OMG!!! My central air unit is now running half the time it did previously. The house stays cool finally! And these guys clean up after themselves. The cost and quality workmanship are terrific! If you are tired of sending your money to Entergy… call Jennifer at Fontenot Insulation. My only regret is all these years I paid high light bills when insulating could have saved me so much money!

Had open cell spray foam retrofitted to an existing 50 year old home. Workers seemed competent, and were friendly. Looks like a good install to my untrained eye. There were a few mistakes that had to be rectified. Nothing big, and it was properly repaired. Properly. More importantly, the very experienced painter ended up repairing more of my garage acoustic ceiling than he needed to. So now my whole garage looks better, not just their 2 accidents. This was in a truss roof, with 2x4s instead of 2x6. I will say that from the first night the temperature felt more even in the house. Will not install spray foam in summer. I'm one of the last this year, sorry. It's just 130° up there and these guys are wearing non breathable suits to protect their clothing and arms and respirators with face shields. The real deal masks. I feel like that decision is geared toward protecting their talent. And I like it. We should all have a boss making sure we aren't asked to do dangerous things.
The best heat treatment company in all of New Orleans, highly recommended.

WOW! Extremely happy with our spray foam attic! I was very hesitant in having this done after reading so many bad stories on the internet where people have had issue with odor and health problems after spraying their homes. I expressed all of my concerns and questions to Ira and he answered all of them and encouraged me to do my own research as well. (These problems tend to be from bad installation by untrained and uncertified individuals) He is very knowledgeable and informative as is his entire crew. Everyone that came to the house was professional, courteous, well prepared, knowledgeable, and just made me feel at ease. They were all able to answer any of my questions and I had a bunch. The process was expedited quickly. They were very prompt to come out and inspect, provide the quote, and then get started right away with the installation. I glad I made the call to Sunlight Contractors and will definitely use them in the future for my contracting needs.
Absolutely the best experience. Extremely knowledgeable. They were timely and honest! I will admit I was worried about surprise fees but they were true to their word. There was even an unforeseen issue that popped up and the owner said they should have caught it and he covered the extra material costs and didn’t charge me a thing extra. I highly recommend sunlight contractors and will be using them on a different house we own.
Incredibly professional company. I had insulation that had degraded after a 100 years and was a mess. The folks at Sunlight got me fixed up in no time and made sure I was always happy. The entire staff that worked on my project were incredibly hard working and very friendly. They were also very fairly priced. It is with pleasure that I would highly recommend Sunlight. These guys know what they are doing!

J’rell and his crew member did an outstanding job! J’rell, the team lead, explained every step of the process and answered all of our questions as they made our home more energy efficient. They arrived on time and were friendly as well.
Received excellent service from Diversified. I can tell the difference in the air quality of my home. More importantly, J’Rell was so knowledgeable and worked diligently to complete the job. I highly recommend them for your duct cleaning.
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.

I really appreciate Coastal Insulation. Mr.Joe knew exactly what was needed to Insulate our home. I really appreciated his professionalism & the price was fair. He kept me informed about the timing schedule and any delayes. The crew was incredibly nice and knew exactly what needed to be done.They worked quickly and effectively to accomplish it. I wish all home improvement companies worked quickly and showed respect for home owners and their property. If you have an insulation needs, call Costal Insulation.
Please learn to park omg. If they do work as well as they park go somewhere else
One of their drivers in truck 5299 almost ran me off the road on Hwy 607 by Stennis Space Rest Stop when the lane changes because he or she was in a hurry and I mean over 90 mph. At 8:30 in the evening and slick roads, this person is a hazard to themselves, others, and the company they work for. This isn’t the first time I have had a bad experience on the road with this company over the past few years, but this time I was able to get a picture of the truck number. A company that has this little care about how their drivers treat the public makes me wonder how they treat their customers.
