Yesterday I was at an inspection and saw some white powdery substance on the rafters then saw the same in the crawlspace on some floor joists. The crawlspace floor was wet in a large portion. Any ideas what it is and if I should call it out in my report?
Looks like reused lumber, looks like white wash
From NE Oklahoma it looks like form boards being re-used.
Common practice around here.
I was thinking that as well. But wanted to make sure I wasn’t missing something. Especially with the crawl being damp/wet. And it isn’t wide spread. The foundation walls were poured concrete with lumber forms. Thanks
Look at the pattern… do you see the well defined, abrupt and random, interruptions of the white substance? That does not normally happen with mold/mildew. Mold and mildew don’t just stop, they’ll have a more uniform spread pattern.
Just verifying my thoughts. I appreciate the input. And tutorial, I love this forum for that purpose. Inspectors helping inspectors. I’ve only been doing inspections just under a year and always want to make sure I’m accurate in my thought process. Thank You for your response.
Just wondering what you said about the wet and lack of a vapour barrier?
I wrote the moisture issue up along with other moisture related issues. And recommended a moisture barrier along with a further evaluation and correction by a qualified professional.
