I don't have personal experience with a next door dry cleaner, but I do know that the older ones used nasty chemicals that travel.

Chemicals can accelerate corrosion.

It sounds like you can pay to treat the outside of the property with some kind of chemical spray that keeps the bugs away, but I've heard that spray will quickly wash away and lose its effectiveness6) Crawl space - open the vents in the summer and close in the winter to promote air flow in warm weather and keep heat in during cold weather.

Yes, it's an extra expense, but if the well has failed, you can be in for a significant bill.If the property is on private septic, you should also check for proper separation from the leaching field (100 feet around here) as well as purity (chemicals, e.coli, etc).When I bought my home here in Plymouth, I tested the well water. 

As for the staining, it is common for our systems to change color if sulphuric acid or some other chemicals hit them continuously.

The cleaning company used the wrong chemicals to clean dirty spots and have damaged the carpet in several places (seems like permanent damage).

Good chemicals that are agitated into the carpet and then extracted will take a lot of stains out. 

They use Termidor, which seems to be more "once and done" compared to some of the cheaper no name chemicals.
