A large white space below the footer but only for one page!

Hi…

I’m working on this website with wordpress …. http://www.idipac.com and experiencing problems with the home page size; there’s a massive white space below the footer. It doesn’t appear on any other pages, just the home page.

I’ve seen other forums and there seem to be a similar issue when there are post and comments, however with my website, it only occur on the home page 🙁

Any ideas?
