Jersey State Insulations

I was very pleased with the work done by this company. They were very cooperative and easy to deal with. Their price was very reasonable. I would hire this company again - in fact, after they finished my project, I asked them for a quote on another.

Excellent price. Excellent communication in a job done perfectly..

Very professional service. I called for two estimates and Sebastion is the only one who showed up. He showed up on time, let me know he was coming and did the same on the day of the service. He came with a great crew, they were fast, efficient, polite, and cleaned up after themselves. I will not hesitate to use them again.

⭐⭐⭐⭐⭐ Excellent Work by Sebastian – Jersey State Insulations We recently had insulation work completed by Jersey State Insulations, and Sebastian and his team did an outstanding job. From the beginning, Sebastian was professional, knowledgeable, and very easy to work with. He took the time to explain the process, recommended the right insulation for our space, and made sure everything was properly sealed and installed. The workmanship was clean, efficient, and done with great attention to detail. No shortcuts — just solid, quality work. Sebastian was punctual, respectful of our home, and left the area clean after the job was finished. We’ve already noticed an improvement in comfort. I highly recommend Sebastian and Jersey State Insulations to anyone looking for reliable and professional insulation services.

These guys are the best! The job was done on time and very professionally. The results have been excellent. When they left, our home and yard were so clean that you would never have known they had been here. They are very polite and the price for the work was very good. We highly recommend them.

Great experience. Sebastian was a pleasure to deal with. Great communication start to finish. Everything started and ended on time. Great job as far as I can tell. No problem using him again for the next project.

The entire crew was personable, professional, punctual and very experienced. I was kept informed of progress, informed of any issues and "kept in the loop"at all times. They assayed the job and did it very well without wasting time or material. The cleanup was done very well. I would hire them for any additional work I may need in the future without a seconds' thought. I also thank Angi for having N J Insulators in their list of contractors.

They did a great job and were very thorough. Also cleaned up everything. I would highly recommend them!

Sebastian and Team, They arrived on time and ready to work today. They removed the old insulation and trucked it away in sealed bags. The fiberglass was placed in their truck and they installed the new foam insulation. They took several pictures and send them to my wife and she was very pleased. Sebastian charged a fare price and would recommend him as a insulation Pro.

I recently hired Sebastian and his company to install new fiberglass insulation and Densepack in my attic. I found them to be extremely professional. They did the work as quoted, cleaned up after they were done and took all the trash away. I would highly recommend them.

I can’t say enough nice things about Jersey State Insulation. Sebastian and his crew are absolutely amazing. They work very hard and are very conscientious of your home. When they did the insulation on my home they were very careful when moving things around and cleaning up after the job was done. Sebastian is very friendly and made every effort to explain everything and make sure I was happy with the work being done. I met with other insulation companies, but none seemed nearly as competent as Jersey State. The others wanted to charge me a lot more for something I didnt think I needed. The others though my problem was only the attic. Sebastian inspected the attic and said there was nothing it needed. Other contractors didn’t even want to attempt blow-in insulation, but Sebastian and his crew did it and the result is fantastic

Sebastian and his team did a great job on insulating our sun porch. They went way above and beyond. I would highly recommend them.

Seba. Sabastian and his crew did an excellent job,better than expected. They will very polite and cleaned up afterward. I would definitely hire them again and recommend them highly.

Sebastian and his team were absolutely outstanding! From start to finish, they demonstrated exceptional communication, responsiveness, efficiency, and professionalism. They truly went above and beyond, even completing the project ahead of schedule—a rare feat in construction! Their attention to detail was remarkable; they took the time to thoroughly explain the materials and process, ensuring we were comfortable every step of the way. The team maintained an incredibly clean worksite and delivered flawless results. I couldn’t be happier with their work, and I’ll 100% be hiring Sebastian for all my future insulation and painting projects! Highly recommend!

Sebastian was very thorough with his job proposal and explanation. Very neat clean and prompt with work and his crew members were very cordial and professional.

This company far exceeded expectations. When I asked them to install the attic insulation in a way that was more labor intensive than what we agreed to in the original contract, they did it without asking for a penny more. They power washed the vinyl siding where their installation had left some dirty smudges, but didn’t stop there, and power washed the entire house. This was not in the contract at all, but they offered it because they wanted to do a good job. Again, not a penny was requested for this extra work. My wife and I decided to give them a large tip, but even with that the cost was far less than the estimates we got from other contractors. I would give them my highest recommendation!
