If you have any questions about the quality or structure of your foundation....contact Everdry Waterproofing of Columbus Ohio for a free foundation accessment.
However, an alternative might be to ask the builder to provide you with documentation from a qualified/certified engineer to verify the basement floor is sufficient per the building code. This is another way to get a third-party approval without paying for a full home inspection.
Again, I'd still recommend getting the inspection. The peace of mind alone is worth the $295.
Get an inspection. FYI, these are my opinions and I am NOT an inspector and I'm not represent you in any way.
Best of luck!
