:) Thanks for your reply...
It's "Water Everywhere" and "Explosions", I've responded either with immediately calling for the professional repairman (wow, those are expensive) or going there myself. The events so far have always ended with praise with my quick response, the lot is praised and it's rating has risen, those are good, but they also occur once a week or more. My sims own house doesn't have so much attention and yet it's never had so many problems in such a short time. I've maxed out the repair skill in just a short time doing this. This can't be intended, or I wouldn't think so at least. Maybe this has no bearing on the situation but I even have the Sprinkler System there, thought it may or may help influence or prevent the No Skills townies from Burning my other house down trying to feed themselves.
