Owners of all older homes should consider having their ground rods/electrodes replaced by a licensed electrician.

Updating Residential Grounding
This installation may have met code in years past, but now needs to be updated. The single electrode of undetermined length should be replaced with two code-compliant grounding electrodes, unless testing proves just one has a resistance to ground of 25 ohms or less. Otherwise, there is a good probability that the house isn’t well grounded which could be a danger to life and property.
