"Marcos was friendly and fast, and flexible in scheduling. He and his crew did a great job for us in removing asbestos tiles from our basement flooring so we could have interior drain tiling installed. In the process, they also discovered some mold, which they were able to deal with at the same time. He came with a large crew, so they finished a large job very quickly. The space was well cleaned afterwards, and we received the necessary clearances. Highly recommend."

"Jon at Finest Home Inspection was great. He walked us through the inspection and his findings on site as well as answered our specific questions about the house. Our inspection report was provided the same day and the radon test results were provided as soon as they were available. He let us know what he wasn't able to check because there were tenants living in the house. He gave us his honest opinion on the house when we asked him. It can be difficult to assess the thoroughness of a home inspection, but now that we've been living in our home for a while, I am confident our home inspection was thorough. We haven't run into any issues that were not addressed in the home inspection. I would recommend Finest Home Inspection."
