Home checks are usually conducted by certified home inspectors or professional engineers.  Home checks usually include checks of the exterior, interior, structure, electrical system, plumbing system, and heating and air conditioning systems of a home.

Finding out what types of checks a home may need is a good bit of information to know before hiring the services of a Professional Engineer.  Although these services are mostly suggested for those buying a home, it doesn't hurt the seller to know what to look for as well.  Assessing which additions or improvements a home may need (if any) can save both parties time and money.  A check may also be good for those planning on remodeling or making general home improvements.
