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!
We chose Sunlight Contractors after thoroughly researching the market, and we’re so glad we did. From the very beginning, Ira and his team stood out with their excellent communication and transparency. They gave us all the information we needed to make an informed decision, even sharing what to look out for if we ended up going with another company. We needed old insulation removed, but Sunlight also gave us great advice about additional steps we might want to consider, like treating the wood to protect it moving forward. They spent a lot of time helping us think through the project and discussing different options to make sure it would be a success. Sunlight provided a great estimate, and on the day of the job, the crew arrived on time and were incredibly professional and friendly. They worked with care and efficiency, and we were so impressed by their attention to detail—especially how thoroughly they cleaned up after a big job on such a hot and humid day. We were very happy working with Sunlight Contractors and wouldn’t hesitate to work with them again in the future. Highly recommend!
After our house was damaged by a motor vehicle accident, we contacted sunlight contractors to help us with the repair. They did an inspection and also gave us excellent referrals for people in unrelated areas of house maintenance. Ira and his team were very communicative, always respectful, and always looking out for the best for us and our home. During the work, the damage was noted to be more extensive than previously thought. Ira would call me and keep me up-to-date, and we got through these difficult times respectfully as a team. They let me know what was most important, were understanding of our financial situation, and were not quoting additional unnecessary services to price gouge us. The final product is beautiful, you could never tell that the house went through an accident. I would 100% recommend Ira and sunlight contractors for any repair. This is a honest, hardworking, and skilled contractor company.

Thanks to Intech my home has been much cooler in the summer and i have saved over $200 on my electric bill.
I cannot say enough wonderful things about In Tech Insulation and its owner, Greg. From start to finish, Greg proved to be honest, extremely knowledgeable, and genuinely dedicated to the quality of his workmanship. It’s rare to find someone who takes this much pride in what they do, and it shows in every step of the process. Before any work began, Greg took the time to fully evaluate my home, discussing in detail what was needed and why. He carefully listened to my concerns and made sure I understood all of my options. What impressed me even more was the way he coordinated with the other contractors involved. He didn’t just show up and do his part—he communicated thoroughly with everyone to ensure that the entire team was aligned and working toward the same goal. My home was built in 1900, which meant it required several different types of insulation to be effective. Greg approached the project with exceptional skill and attention to detail. The results speak for themselves—my home is more comfortable, efficient, and protected than it has been in years. I highly recommend In Tech Insulation to anyone seeking a professional who truly knows his craft, stands by his work, and delivers outstanding results. If you want honesty, expertise, and pride in performance, look no further than Greg and his team!

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.

PolyCo did an amazing job insulating my attic with spray foam. The difference is unbelievable my home feels cooler, and my energy bills are already lower. The team was professional, quick, and super clean. I highly recommend them if you’re looking to upgrade your attic insulation in Baton Rouge!
I love this company! They are top tier and very professional! They are also very quick and efficient when getting the job done. I was worried about clean up after the spray application but they handled it’s all! I will be using for any future needs!
Excellent service and noticeable results! I hired PolyCo to insulate my attic with spray foam and was very impressed. The team was punctual, professional, and the difference in indoor temperature was immediate. Highly recommend them if you’re looking for quality and energy efficiency!

Excellent communication, provided all that was agreed to in a prompt and professional manner. Did a thorough job, including taking time on prep work prior (doing it the right way - with baffles and depth gauges). The installation of the blown insulation was up to or exceeding the spec, and we have the photos to prove it! 1 week later - attached is my daily report from Entergy for the past week - even better than I hoped. BTW, Monday's high was 93 degrees.
Incredible work, and fast too! Their insulation job brought my HVAC's kWh/CDH from 0.075 to 0.055, saving me about $20 per month in cooling costs (in the peak of summer too..)
I am writing to express my complete satisfaction with Koala of Baton Rouge. From the initial consultation to the completion of the work, my experience was excellent. The salesman was thorough and knowledgeable, and the work crew did an outstanding job. My 25-year-old house is now significantly more comfortable, and I anticipate a considerable reduction in my Entergy bill. I highly recommend Koala of Baton Rouge to anyone considering insulation updates. You will be very pleased with the results!

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!
