Hmmm. I would probably be doing some due-diligence prior to hiring a company called "Inspecta-Homes" lol.
Do you know if the inspection company is licensed/certified (a requirement in most states)? Bonded and/or E&O insurance? (also a requirement in most states)? Is that license/certification in good standing? Any previous or outstanding licensing/certification board complaints? Are they ASHI members? BBB rating? Any Yelp reviews? Etc. Etc.
Also, in a lot of cases, home inspectors are not allowed to do "intrusive" inspections (which is BS IMO). They have legal grounds to stand behind not removing switch plates, or looking behind fixed appliances, etc. However, that is not an excuse for incompetence and/or negligence.
If you have "intentionally hidden" items, then it sounds like you don't have an inspection issue, as much as you have a seller disclosure issue. If you can prove that the seller intentionally hid potentially dangerous problems/defects, then you have a bit of leverage. Disclosure is one of the few things that a seller can get nailed to the wall for, and one of the few things that can include criminal penalties, not just civil.
