 4 POINT INSPECTION PURPOSE AND WHAT INSPECTORS LOOK FOR DURING A FOUR POINT INSPECION. 

A 4 point inspection is requested by an insurance company on a house most of the time that is 30 - 40 years old when switching insurance or in the course of the house being insured with your current insurance company.  This inspection lets the insurance company verify that the four major system in the house are in good working order.  These systems are Roof, AC / heat, Electrical, and plumbing.   

ELECTRICAL

  • The electrical system should be in good general condition. All receptacles should be working properly.
  • Main electrical panels and sub- panels should have proper covers and labeling. 
  • Main electrical panels and sub panels should be of sufficient service size.
  • All wiring should be properly covered and protected. 
  • If you have a main electrical panel with a service size of less then 100 AMPS an insurance company will most likely not insure you. 
    
CONDITIONS OF THE ELECTRCAL SYSTEM THAT MIGHT WARRANT AN INSURANCE COMPANY NOT TO INSURE YOUR HOUSE.

  • There are several brands / types of panels that have been proven over the years to be fire hazards and are not made anymore.  These panels are still in existence in homes everywhere. These panel types include: Zinsco, Challenger, Federal Pacific Stab Lock, and old Edison style screw in fuse panels.
  • Knob and tube wiring.
  • Aluminum branch circuit wiring.
  • Cloth wiring

PLUMBING


  • There should be no active leaks present at the time of the inspection.
  • Polybutylene piping if installed most insurance companies will not insure you house.
  • Water heater should have the TPR valve present and no active leaks.
  • Sinks and toilets should have adequate water pressure and drainage.
  • Although not a requirement all sinks and toilets should have quick shut off valves installed.
  • Copper is acceptable piping but CPVC piping is better.
  • Lead piping will not be insured.
  • Galvanized piping is questionable. Some insurance companies will insure it.
  • Black iron piping is questionable. Some insurance companies will insure it.

Part of a 4 point inspection is looking at the water heater.  Insurance company wants to know:

  • Location of the water heater
  • Water heater age, brand, and capacity.
  • They want to know that the TPR valve is present.
  • What kind of supply piping is installed.
  • Note whether quick shut off valves are installed.
  • There should be no active leaks at the time of the inspection.

AC / HEATING


4 point inspection will also report on your AC / HEATING system.  The insurance company want to know:

  • If there are any active leaks.
  • Thermostat location.
  • Adequate drainage of the condensate lines.

I also test the difference between the supply and return vent with an infrared camera.  There should be at least 14-22 degrees difference.


ROOFING


The insurance company wants to know:

  • What type of roof covering exists on the structure. (metal, composition shingles, 3 tab shingles, roll roofing etc.
  • Age of roofing or estimated age. Preferably permit information can be found and included in the report. Sometimes permit information cannot be found.
  • No active leaks at the time of the inspection.
  • House elevation pictures. (Front, back, and both sides of structure. Wind mitigation report goes much more in depth on the roofing and hurricane protection features of a structure. See our article on wind mitigation.

SUMMARY:  A  four point inspection let's an insurance company see that the 4 major systems of a house are in good working order.  This report will make you eligible for insurance on houses over 20 years old. The roof, AC / HEAT, plumbing, electrical. Typically this report just lets the insurance company know that the house is insurable.  Pictures are required as documentation of every system checked during the inspection.
