I am very pleased with the service we received from Octagon. From the start, Jason was very involved, professional and able to address our concerns about evidence of mice in our basement and crawlspace. He designed a plan to deep clean both spaces, removing any lingering odor and purify the air. Michelle and Tim were an efficient and thorough team, and I would heartily recommend them and this company.

We had Amber from the Barrington office here on September 23, 2025 for water damage related cleanup and she was just amazing. Communicated with us on every step and performed the work in an excellent manner. She also cleaned up thoroughly when she left. Highly recommend her and will ask for her next time we use Octagon.

I recently hired Octagon to handle mold remediation at my home, and I couldn’t be happier with the experience. From start to finish, Jason, Chris, Tim, Cooper, and Bo were professional, knowledgeable, and thorough.They responded quickly to my initial inquiry and scheduled an inspection right away. During the assessment, Jason explained the problem clearly and walked me through their proposed plan step by step, which immediately put me at ease.Chris, Tim, Cooper, and Bo arrived on time each day, worked efficiently, and took great care to protect the rest of my home from contamination. They were respectful, courteous, and made sure to clean up thoroughly after completing the work.What impressed me most was their attention to detail and commitment to ensuring the mold issue was completely resolved. They even followed up after the job was finished to make sure everything was satisfactory and to answer any lingering questions.I highly recommend Octagon to anyone facing mold issues. It’s rare to find a company that combines technical expertise with such outstanding customer service. I’m grateful to have my home safe and healthy again — Thank you!

Kitchen flooded, I called Octagon and they were in my house in an hour. Amber and Michelle were VERY clean and professional. I didn't have to lift a finger and they cleaned up, got me dry and ready for the next step! Steven help organize everything with my insurance, again I had to do very little to help with that as well. 10/10 would recommend!

Amber, Anthony, and Michelle did an incredible job on our attic mold remediation and insulation removal project - under very uncomfortable high temperature conditions. They were hard working, efficient and extremely respectful. They arrived on time and did not leave until the workspace was clean and vacuumed, and all furniture was moved back into their original place.This was my second project with Octagon and I will be using them again in the future. I highly recommend you use them as well.
