"I highly recommend Octagon Cleaning and Restoration. We recently purchased a house on the water and discovered that we had a mold issue in our basement. Matt and his crew were professional, informed us what needed to be done and completely eliminated the mold and the musty smell. Matt was very responsive to my texts, answered all my questions and a great representative of Octagon."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."
