I'm looking to purchase a home that is only 10 years old, but has a finished basement. There's various home inspection "packages" that are offered with the companies I've looked into. The mid-line features an "Infra-red scan" that can theoretically detect potential water problems behind the basement walls (this is about $200 extra), as well as an "air quality" test where they identify allergens in the home (which is, like, $400 extra).
Are either of these tests worth it, or, rather, are they actually able to find anything important? Would the infra-red scan really be able to find water behind finished basement walls? Would the allergen test be able to discover hidden mold or anything like that?
My family is moderately allergic to dust, and has some mild mold allergies... On a 10 year old home is there are real danger of having abnormal levels of mold/dust that would be found with the whole home air quality test?
