This Weeks Discoveries. 5/9/2018
Wenatchee Home Inspections

Another addition in a week of discovery.

As a Home Inspector, Structural Pest Inspector and Home Inspection Licensing Instructor I try to keep up with new products, manufacturer or trade information, code information or just interesting content that may help those who are in the profession or looking to further educate themselves.  The material may be articles, documents, video link,vendor sites, technical materials or even an interesting code questions.

Below is a list of some interesting items found in the last week.
