Donald was available on short notice, spent three hours at the house, and spoke with me a few times after the inspection to answer some of my questions. He's clearly very knowledgeable, and tough, though he may have been too tough on a few issues. There were some significant issues in the inspection, so I paid to have two other subject experts come out to get a second opinion on some of Donald's concerns. Neither expert had the same level of concern. So, maybe he was right, and maybe not - I'll let you know in 5 years after I've lived in the house for a while and know its true condition!
