The website of the National Association of Home Builders has an entire section on mold.
Also, on the same site, they do NOT suggest going for a professional mold assessment.
We aren’t pointing fingers, but we would like to note that a bad builder can be the victim of a mold lawsuit. So when a builder (who can be sued for causing mold by installing bad plumbing, a bad roof, faulty moisture barriers, building a leaky basement or whatever) might not want someone stuck with a poorly built property to get a qualified, legally sound assessment. I’m just sayin’. We’re not defaming the industry–There are some fantastic and honorable builders out there, but Caveat Emptor.
If you’re in California, you might want to give us a call and see about getting an assessment from Byebyemold.
