I saw this video several years ago when I first leaned of Corbett Lunsford. Shortly after, I purchased his book, Home Performance Diagnostics, a book on different testing methods for evaluating a home’s performance. You can check out Corbett’s YouTube channel here, (1171) Home Performance – YouTube
The video struck a nerve with me, there are so many rural homes built in my area that have no inspections or performance testing conducted, they really are like the video. If you are a homeowner, ask the contractor for performance testing, and if you are a contractor, find someone in your area to partner with, they may help to make you a better builder.
