Home Inspector 5 Star Review

Bob S.

Nick Onega was excellent. He was on time and well-prepared, and he worked methodically and efficiently. My wife and I were present during the inspection and he explained his findings and observations at each stage, and he answered all of our questions in a clear and understandable manner. He prepared his inspection report promptly, and it was clear and well-organized. We were 100% satisfied and would highly recommend his services to any seller looking for a home inspector.
