Hey Brian,
Your header block had a bunch of extra lines in it. This happens sometimes from time to time when a plug-in conflicts with the page editor. I just went directly to your block page:
http://www.wall2wallhomeinspections.com/admin/build/block and edited the block for your header (note: this only works because you're still logged in).
You can go ahead and continue working on it. If you continue to have problems, make sure you don't have multiple browser windows open while you're working on your site and turn off any plugins you have running.
