Hello all! Have appreciated reading all of the helpful comments usually found on the forum.
I inspected a home with masonite/hardboard siding which had significant waves with no other indications of issues. Thinking that some of you migh have seen something similar and could enlighten me on possible causes. This is a home built in 1978 with a crawl space with minimal to no cracking in the foundation and minimal movement inside.
Thanks in advance for your input!
