I was really insistent. One email after the other. Three times the workers came the long distance but did only some insufficient and incomplete repair. At last I offered to pay additional fees for proper work. In my opinion the main thing is the mice won't be able to enter the insulation from underneath.

I assume the company hasn't had a customer like me before - someone who is crawling under the house! An Australian wouldn't do it ever. But now I'm satisfied. Even silicone around the pipes.
