Certifications do not mean that you know everything about a given topic. Only that you have a good understanding of a particular topic. All home inspectors in Washington are required to have 24 hours of continuing education to renew their license. A good home inspector is always continuing his/her education through conventions, books, online courses and forums.
Why should you trust me to inspect your home? As well as the required insurances for the State of Washington, InterNACHI trusts me and they are willing to back up that trust through the Honor Guarantee for my Clients and Negligent Referral Protection for Realtors.
