Issue with display of blog page

Hi,

I've got an issue with the way my blog displays. It doesn't always do it, sometimes on a specific blog, sometimes the main blog page, sometimes when I access it from the nav menu, sometimes the main menu. I know this is kind of random, but that's what it is. See attachment for the image. My website can be found at www.all-american-remodelers,com

FYI - web design is new to me, I'm better with swinging a hammer... You may have to be very specific in answering my question.

Thanks a bunch!

Roy
