"The perimeter drain around my foundation was no longer working. Every time it would rain, I had water behind the foundation wall and developed a good size crack and that would be where the water came in. Also from the chimney door. Richard called me on a Sunday morning, came out later that day and explained it all! He explained every detail about what needed to be done .Excavating, drainage, crack sealing, and coating. By the way this was done January-February. I can't say enough about Richard, Zack and Brad. I would highly recommend Forrest Excavation. Thank you Richard"

"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."
