"Shawn was very professional, timely, and informative. He performed a thorough/comprehensive full house, radon, and termite inspection on my new construction home. The report was extremely helpful for negotiating with our builders. Shawn found problems that their inspector had not. He even made ergonomic recommendations. Shawn was very prompt too. We had our inspection report the same afternoon as our inspection. I also found that he was extremely reasonable price wise when compared to similar professional inspection companies. I definitely recommend that you use Eagle Eye Inspection services! Thank you Shawn!"
