"Woke up to major water damage on a Sunday. I called Octagon and they were on site within 2 hours. They immediately set up to control the damage and handled everything with regard to my insurance claim. The staff were extremely professional and very pleasant. They arrived on time and kept me informed every step of the way. They clearly went above and beyond to make sure the job was done right. Their expertise is obvious and the caring they have for the customer is evident. Once I called them, all I had to do was wait till my house was dry again, they handled everything. would recommend Octagon with out any reservation! Cost of $2500 reported is full cost, I only paid the insurance deductible."

"A great team. They not only did the work, they coordinated with floor refinishing crew and insulating crew. They also let us know when we had heating problems. They have more work to do for me; I certainly wouldn't hesitate to call on them in the future. This is a very responsible team. Highly recommended."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."
