How do I make footer at the bottom of static page?

I'm creating a static page for my home page, but I still want the "home box left, home box center, home box right" to show up at the bottom like it does everywhere else on my site. Is there an easy way to do this or a plug-in that allows it to happen.

Here is a link to my site:

(if you click on any menu items you will see what I want at the bottom)

Thanks
