I think an underrated way to deal with this phenomenon is proper self-marketing. Talk endlessly what you have done to prevent catastrophe. Describe the avoided catastrophes vividly so that people get a clear picture.
Sometimes you can't quantify actual avoided things. For example you can't prove that a regulation stove actually prevented what could have been a kitchen fire.
The caveat to this is to make sure hope doesn't turn into expectation. Expectation can turn into sourness when the others don't reciprocate. Also, some people feel when you do something just because you expect something in exchange, and that tends to make them not reciprocate.
