A four-point Inspection (4-point insurance inspection) is typically performed for a homeowner when requested by their insurance company. The inspection is often a requirement when obtaining a new homeowners insurance policy or renewing an existing policy.
 
The inspection includes a limited scope evaluation of the following four systems: (1) roofing, (2) electrical system, (3) central heating system, and (4) plumbing system. The intent of the inspection is to determine the age and general condition of these systems.

Note: this type of insurance inspection should not be confused with a "standard home inspection" which is broader in scope in regards to the areas of the home which are covered and in detail.
 
Note: inspection requirements for insurance may not include all the systems of a 4-Point Inspection; sometimes all that is required is the evaluation of a specific system of the house, such as the roofing, or a specific combination of systems. Partial inspection services are available to fit your specific needs.
